Clayton. This is just fantastic. Thank you so much for putting this stuff up for all to learn from. Cheers from a 'Land Downunder'. If I could give a million thumbs up I would.
This is awesome, I appreciate your work and thank you for sharing this with us. Love the way it runs, so smoothly :). Again, thank you a lot for sharing, this help me a lot to keep learning.
Hi Clayton, I would like to install your project on an ESP32 cam. My question is it possible?
There isn't a simple solution for something like that. You would need something similar to the OpenCV library to do the object detection and image manipulation, but a very reduced and streamlined version to run on the ESP32. I haven't seen anything like that. Memory is going to be a problem. Most image libraries want to hold a full image in memory in order to work on it.
Thank you for the quick reply. Then I will try it with the PI 4. Maybe you can make a video how to install everything exactly in what order. Please continue to do so that helps many users who are not so fit with the software
I've never tried it, but I think a Pi4 should work, although you might not get as high of a frame rate as you could on a larger machine.
Thank you Clayton! Especially for sharing the code. and how to find the object`s center point and the farthest distance from the center point
That was really helpful, thank you so much, keep up the great work.
Thank you Clayton! Especially for sharing the code. For anyone who wants to write the lengths file, the variables are ylen, xlen at #503-508ish in camruler.py. If it outputs too much data maybe adjust line 360 'time.sleep(0.1)' to something bigger? Another cheers from Down under.
Nice Project! Thanks for making this available for those of us learning. I hope to use this to measure the size of peony flowers this summer for my girlfriend's small flower farm. She will think I am a genius!!
Nice! Hey, are those your CNC tools in your videos? Do you have a CNC shop?
@@ClaytonDarwin I set up a high end MakerSpace for a school in Shanghai the last five years. Couldn't get back because of Covid--so now I only have my own 3D printer, cricut cutter and Maslow CNC router to play with. Need to find another school to set up here in the States.
Very cool. Did you see my recent SCARA plotter ( th-cam.com/video/djyMaqPY0tQ/w-d-xo.html ). I was trying to come up with something that anybody could build (i.e. teenagers). I would like to develop that more and do some other education-oriented projects at some point. Working on an ESP32 funboard at the moment (in my spare time).
@@ClaytonDarwin Your plotter is nice.
I had just started working with the Chinese Homework Machine and was going to have kids try and make one of them. www.scmp.com/yp/discover/entertainment/tech-gaming/article/3060907/chinese-schoolgirl-caught-using-robot-write
It is another simple plotter that costs about $100 over there. A clever mechanism for x-y motion.
I've seen those. Haven't had time to make one.
This is awesome. Thank you so much for this. Could you please make a video about the how you plan the architecture for a project like this?
Thanks. Glad you like it. I'm not sure about an architecture video. I'm self-taught for the most part, so I don't have much theory. I just work in parts, getting each function to work correctly, and then try to combine them into a logical, orderly, and efficient whole. I re-write many times, and I often write my own wrappers and libraries if the ones available don't do what I want. Lots of trial and error. Lots of failures. Lots of reading. Lots of Google queries.
Well done Clyton. Good job and thanks
Beautifully explained !!
Nice work Clayton!!! I was wondering how can you implement real time angle meauserement in this project ??
You would have to identify 3 points and then do a little trigonometry. OpenCV has quite a few options for things like that.
This is awesome. if you have more time it will be very good if you make series tutorial of camera measurement of any object, for example key measurement as the object to measure the length and the height of each part of the key like the notches depth, the ridges height, the shoulder distance etc. Thank you very much.
Good idea. I haven't had time lately to return to this project. But this can certainly be a template for a more complex project like what you are describing.
Hello clayton
Nice video, Can you Tel what camera and Lense you Are using for This project?
Also what version of openmv Are you using?
I have a USB3 camera somebody sent to me. I think it's 1080p, up to 60fps. There is a video about it. I pit an adjustable lens on it, and it was probably set at about 22-25mm. But pretty much anything will work.
I just bought a webcam with a built-in ring light, to help prevent shadow issues. Also, am experimenting with round stickers at each corner of the white background sheet. Since these have a fixed diameter, circular object diameter can be measured as a percentage of the diameter of the round stickers, then actual size and position can be calculated even when the camera is moved, by constantly recalculating positions and sizes in a live video stream. Have you tried anything like this?
Two good ideas. 👍 The lens distortion is fixed, so once you have it calibrated, you should be able to adjust based on the stickers. I think.
Hi Clayton, very interesting project, would you please elaborate on the logic on how the menu system works. Your code is very neat and tidy, superb!
I'll have to go and look at it. Can't remember off hand.
All events are handled by either the key_event() or mouse_event() functions. The mouse event function must be registered as a callback, while the key event function can be called at the bottom of the main loop. The event functions basically read event data a set global variables. The main loop, then uses the variables to decide what action to perform (and also what values the use).
Hey Clayton - Amazing work!! Do you know the equivalent command for windows to check on the camera ID piece by chance?
Sorry. Haven't messed with windows for a while. Isn't there a devices list?
I don't know what was going through the minds of the people who rated this video with a thumbs down, but I, like a host of others, appreciate your making these videos.
Thanks, boss.
Too much satisfactory to watch this
Dearest Clayton Darwin ;
could I use this code for my purpose of measuring objects?. Is it working in windows? thanks in advance
Excellent. Yes. Use it however you like.
@@ClaytonDarwin thanks with full respect dear
Hello Clayton, ive a question and may you would like to answer, if i use 2 cameras which one for detect and measure reference object and other one for detect and measure another object that i wanna know that dimensions, could it be working on? I wanna make the camera which detect object measure can be adjustable
I think you can combine the ideas in this video with the ideas in my triangulation video and do what you are describing. I haven't done it, but I have thought about it.
@@ClaytonDarwin i wanna make it for my final project in school, thanks for your info. But now I'm stuck on how to use a USB camera when I've done put it in port USB, because when I tried your code I can't change the camera set, please let me know which code that I have to change for setting the camera to camera USB, not camera laptop webcam?
You have to edit the code and set the camera number according to your setup. This is an OpenCV setting.
Could this be used for measuring people's arms length, leg lenghts, etc in real time or from an image?
This uses geometry/trigonometry to calculate distances based on a known distance (the distance from camera to table). You can use a similar algorithm to do the measurements you describe as long as you have a known distance to target measurement.
Cool, I'm glad i get to watch this!. is it possible to rewrite or just add the code and measure the circumference of the circle?
Yes. Any distance could be treated like a diameter and multiplied by pi.
Hello, it's very nice. Your development seems to work very well with square and rectangular objects. Now, what happens if the object doesn't have that shape? For example, a wood shaving, a small piece of paper cut by hand, some shapeless pieces of plastic.
Like the title says, "try it yourself" and then you will know what it can do. Then you can take the code and improve it.
Dear Clayton, this is an amazing video! I would like to use a camera to detect twp things: a fiber tip and the edge side of a metal plate. Could you give me a tip how to make the image recognition best?
Sorry for the late reply. You could definitely add edge detection or image recognition to this using opencv. The best results will be had by closely controlling the environment and lighting to get a clear image.
Thank you for your helpful lesson!
Could you please recommend which camera is better to use for this task and generaly for computer vision? Thank you in advance.
Any USB camera will work. Higher resolution allows more accuracy. Also, I like CS-mount cameras because they give you a lot of high-quality lens choices.
@@ClaytonDarwin How do you zoom in the image in your video? Is it optical zoom or just digital one?
In the video I use digital zoom. It's a feature of an OpenCV window. Will zoom to the sub-pixel level. If you change your zoom manually, you will have to re-calibrate your camera.
Please Help Me Sir!
I just want ask, if I have several object with different size & weight. can I convert the size of bounding box to weight? for example : 12.4 Cm x 5.9 Cm = 1KG. or something like this. " if width 12cm to 13cm and height 5cm to 6cm, print (1KG).. Thanks.
If a 2D area has a direct relationship to weight for the specific objects that you are measuring, then yes. However, this is not the case for random objects.
Great video! You currently rely on a known distance between the camera and the object to identify the dimensions of the object. Would it be feasible to modify the program to infer a distance between the camera and the object if the dimensions of the object are known?
Sure. Same math, just using different variables.
I LOVED THE TUTORIAL. However what units are objects measured in?
Whatever you use during the calibration, that's what it is.
大叔这么厉害 这视频真的是太棒了
Clayton when will you make the real-time object measurement video I am stuck that how to measure the distance from camera using opncv and pytorch?
Distance from camera generally requires 2 cameras unless the target object is of a know size. Like my triangulation video. Also, this script is real time. You can make it an iterator and yield the data rather than plot it if you need to.
Thank you Clayton! I'm just wondering what is the precision of measurement? Is it more than ± 0,1 mm?
Accuracy depends on the camera pixel count, the lens, and how well you calibrate.
Awesome project.
Excellent video sir.
Iam trying with a PTZ camera (analog). Which line in the program will call camera function? By default whether the program takes Laptop camera (inbuilt)? Thanks many
The camera is defined in OpenCV by a number. You can change that near the top of the script. It is marked with a comment.
Due to the nature of video analysis, measurements often change slightly. Is there any way to correct this part?
Higher resolution cameras, better camera calibration, better lighting (and contrast adjustments). Those are main factors that affect measurement.
@@ClaytonDarwin I've seen some document cameras on Amazon that apparently compensate for the distortion issue. These have much higher resolution than most web cams and can focus very closely. On the down side, the depth of field is not great, i.e. these are mostly suited for relatively flat objects such as books or other documents.
Interesting. Might work in this situation.
good video, I appreciate your work. I've a question please, how can I reduce the size of the window which displays the camera's view, because it appears only a part of the writing of modes and configurations... please respond as soon as possible.
You can change it with an OpenCV parameter, or by changing the camera resolution. Or by dragging the frame corner with your mouse.
@@ClaytonDarwin which parameter of OpenCV
Try googling "OpenCV python change window size".
Hi Clayton, This is very piratical and informative, can you point toward references on the topic? BTW, I like these technical topics but I miss the interesting gizmos you build... Cheers, Mitch
Hi Mitch. I don't really have any specific references other than the OpenCV docs. I do lots of googling and reading, and then go back to the docs.
Yeah. You're right. I need to get back to making stuff. I've just been really busy with work the last couple of years and not able to spend as much time in the shop. But making goofy robots is what I like to do. Thanks for reminding me.
Hallo clayton i have a question, from this video why you don't use reference object?
A small reference object assumes that the frame has already been normalised, which is what we are doing with the measurements. Once the frame is normalised, you could use a reference object. Alternatively, you could use a full-frame reference object to normalize the frame. I don't like the one in OpenCV, and I didn't have time to write one myself the day I made this video. This code is just an example, not a product.
Hello, I would like to measure some cylindrical rock samples, in order to know which is the shortest side of the cylinder if the sample is broken and the broken face is diagonal. It would be a kind of irregular polygon where one side would be smaller. How do I make the code create an outline and identify the shortest side, putting the measurement in centimeters?
Probably you could use opencv to detect edges/lines, or possibly a closed polygonal shape, and then build your dimensions from that. That's the way I would start tackling the problem.
Hey Clayton thank you for you file How i can add the capture mode with photos had included detail of x,y axis and width,length of object and then save into our drive?
Do you know how to program? You would have to change the code.
Good job. I want to change your code to make an alarm system.
for example, if the size is smaller or bigger of x start alarm. could you please let me know how should I do it?
Thank you so much.
You will have to add object recognition to prevent false alarms, and then insert the alarm routine after the measurement is calculated.
I'd like to do something like this from a distance but get the GPS location of the pixels instead of their size. Do you think it can be done?
I think so. With a single camera you will need a fixed reference point some exact distance from the camera, and then I think you can work out the distances as done in this video using some trig/geometry. You could then convert it to GPS coordinates from a known point.
Hii, great video, Is this code works on windows, vscode ?
I do not know. I only work on Linux.
would using a single camera like this and something to measure the distance such as a IR distance sensor be able to calulate 3d dimentions of an object such as a mail parcel? My plan is at a larger scale, having the camera approx 1m away from the base. I am unsure if the maths will still work when the distance from camera changes by large amounts.
Yeah, for 3D you will want 2 cameras, and some type of object recognition. You could use two of this setup, or or one of something like the triangulation video. From either, you can get the dimensions you need.
@@ClaytonDarwin so knowing the distance from the camera will still not provide an accurate measurement? i will need 2 cameras to achieve this?
If you know the distance to the table and the distance to the top of the package, then you have the height. If you compensate the 2D area to be accurate at the top of the package, then you have area. Area times height is volume for regular shapes. It would take some adjustments to be able to get the top area for different heights. So, I guess you could do it with one camera and a range finder, but it may be easier with 2 cameras.
hey, I'm struggling to import frame capture and draw, how do I install these libraries?
Did you install opencv for python?
Very good video congratulations. A question, I have a .png image and I would like to find a frame that has it and see how far from the edge of the image is to the edge of the square. Can you make a video helping me? Thanks
Unfortunately, I don't have the time to investigate this at the moment.
@@ClaytonDarwin ok, thanks.
Awesome video.. Would like to know how I could use two cameras to get real time three dimensions of an object using opencv
👍 OpenCV has a distance mapping method included.
Great job, I immediately subscribed, one question, how could i automate measurement and save it in a excel file to do computations consequently?! Thank you sir
In the main loop, about the same place where it writes the values to the frame, you could also write the values into a database or append to CSV file (imports into excel). There are other options, and you may also want to have something you click, otherwise you will have all the stray measurements going into your data.
This was really just a template that you could use to make another application. If you want to automate, you will have to do a lot of filtering to get just the data you want.
@@ClaytonDarwin Thank you so much for the reply, I'll be trying to measure inhibition of bacteria in a culture medium representing a no growth halo, kudos to you, so this video and your project helps me a lot, I can't thank you enough sir, God bless you, peace and love from Iran
One very nice thing about OpenCV is that it has a relatively easy way to train for object recognition. So, you always have the option of adding image recognition into the application. Or maybe more simply shape recognition. This might help you pick your targets automatically. It may be more programming that you are able to do if you are a microbiologist, but if you are in a university or research environment, there is probably a programmer that could help you.
@@ClaytonDarwin indeed sir I am grateful for your advice, I am new to the AI field and I appreciate your work and you sharing your knowledge, God bless you and your family🙏
@Lonesome Herd how did your writing to CSV go, can you share? Thanks
Hello sir, do you also put a list of components that you use in this project into the zip file?
USB camera, desktop PC, ruler.
Hello sir, I want to measure the dimensions of a multi-sized object in one with the measurement frame still in which line do I need to edit?
This is just a demo script. You will need to write your own to adapt to a specific task.
Hello sir, I'm a beginner in software programming and I'm interested in the measurement program you created. I've also accessed the program file through Git Hub. but in the program, I'm confused about how the steps are taken to get the actual unit of measure. can you explain it to me?
The unit of measure depends on what measure you use during calibration. In the example I used mm.
Thanks sir, thats great 👍
when I measure the camera out of focus, how do I make the camera focus?
I use a camera with a resolution of 720p
I can't answer that. The software is not making the camera out of focus.
hey clayton, i have a question, can it detect local image instead of real time? if so, how?
thanks in advance
Sure. You can modify the script to not loop, but instead modify one frame and stop. Just use the OpenCV-Python function to open a file instead of starting the camera. But you will have to go through the same calibration process for the camera you use. Everything depends on the camera setup and calibration.
@@ClaytonDarwin cool, thanks, oh also can it somehow output the detected width and height to terminal?
Yes, just the same as I print other values.
That should be interface for engraving fiber laser program.. Would be awesome
hello sir, I apologize in advance if my English pronunciation is lacking. I would like to ask about the automatic measurement program. especially in the camruler_cal.csv file. I understand that the conversion process is carried out for every 10 pixels based on pixel_base = 10. but I am confused, where are the pixel and scale values in the .csv file obtained from?
When you do the calibration the file is created.
@@ClaytonDarwin However, if I use your program on Git Hub, the .cv file already exists. This means that if I rewrite all your programs, so that mean a new .csv file will be created containing pixel and scale data for calibration?
Whenever you do the calibration a new calibration file is created.
The other csv file is the setup variables.
The calibration do you mean is a measurement to get the cal_range value in config mode?
I have made a setup using a raspberry pi 3b+ and using your code. my issue is the camera quality while running your code is too low for anything to be measured. when turning on the camera by itself the quality is fine. is this due to the processing speed of the pi? and how do i fix it?
I am also getting this error, im not very adept in python so was wondering if you knew what it was or how to fix it?

I think a raspberry pi will have a hard time with the real time frame rate along with the image manipulation required for measuring and display. However, I haven't tried it on a pi, so I'm not really sure.
I'll have a look at the code in the morning. But basically the dictionary doesn't have the item being indexed.
this is just fantastic, just wanted to know how can i use this on two cameras simultaneously
You should be able to run 2 instances. You'll have to explicitly identify the cameras.

I have never used a phone camera as a webcam, but one of my subscribers said it was possible.
Hello sir, How to measure stuffs with YOLO or SSD object detection algorithms?
OpenCV has several object detection methods you could add into the mail loop.
Hello Dear , thanks for the video. Little problem when I hit the A key my scrren frezes up ! Anny idea please ?
No idea. I was using it the other day and it worked fine on my setup. Might be that you have a different key binding for A .
what should i do to store the dimensions obtained in auto mode into an excel sheet?
The easiest thing would be to write data to a .csv file. Comma separated values can be read by any spreadsheet software.
What version/ distro of Linux Are you using?
Latest version of Lubuntu, but any Debian derivative works. I'm using the default Ubuntu install of OpenCV from the time the vid was made.
Hi Clayton. I wrote a script for a non-contact animal measurement. Is it possible your program is fitted for Animal recognition and measurement thereafter write measurement to a csv file? I'm know yolov3 does recognition but I'm not sure of measurement. Kindly respond. Thank you. N.B my device is built on raspberrypi 4 with python3.
Hi Tumininu. You can definitely take my script and adapt it. OpenCV can easily handle movement detection and object recognition, and it is straightforward to write the data to a csv file with Python. However there may be some physical problems to overcome.
The script I wrote uses a single camera, and this requires that you know the distance from the target to the camera in order to determine the measurement. If you don't know the distance to the target, you will have to have a second camera and use triangulation (like my other video) to get the distance. You can then estimate size.
Another problem (maybe) will be the raspi 4. It may not be able to process images fast enough to give you the frame rate you desire. The older raspis were very slow, but I haven't tried it with a new raspi 4. Maybe they are fast enough now.
Thank you Clayton. I installed the OpenCv on my Raaspberry pi 4. It seems its to workon sbb_cv virtual memory. I copied your script from your site into my /home/pi/youtube-projects/OpenCV/camruler folder. i tried running 'python3 camruler.py 0'. it gave error on Line 12 in : No module named 'cv2'. kindly make suggestion.

@@ClaytonDarwin this will be possible if I use it on Paddy rice? I would like to use this to get their length and width.
You could use a similar idea, but not this exact program. You can only estimate size if you have at least one known distance. In thes program i use the distance between the camera and the target (it is fixed) . You would have to add a way to determine a distance. See my video on triangulation. You would need to combine these two methods.

Great vedio, how I could measure the surface of the 3D features
Because you don't know the distance to the target, 3D measurements typically requires 2 cameras and triangulation.
Hi! What camera module you used for that?
Any that will work on your system. I've used several.
Hey now what should I do when I Have to save the data in memory
Add some code to save it.
In this there is a buffer method, I can't understand it its part in the code. Can you help me please !
The script frame_capture.py is a general module that I use for many different application. It works in a separate thread and captures camera frames as they happen. The frames are put into a buffer (holding area) and stored until the main loop can use them. The modules allows the camera to be managed outside the main loop, and prevent frames that are generated by the camera while the main loop is working from being overwritten/lost. In most cases, cameras only have a one-frame buffer. They read a frame and replace the one in the internal buffer, so it you don't read it in time, you lose it.

Hi, I am currently doing this kind of project, but I really don't know how can I start my codes in Python. I already saw your codes but I can't cope up since I'm not familiar with this yet. Can you help me with this, Sir?
And what kind of microcontroller did you used? Thank you, Sir, in advanced.
This video does not use a microcontroller.
To run this code you will have to install Python and Python-OpenCV. Then it should run using a standard web camera over USB.
@@ClaytonDarwin I already have it, Sir.
Sir, can you explain your codes that you used in this video for the beginner like me? I mean, do you have tutorials video on how you write those codes?
@@ClaytonDarwin If I will make a prototype on auto-measuring, what microcontroller you can suggest?
