Rami, your videos are helpful and practical. I'm from Brazil and applying some techniques in my work here.
love your videos helping me with my career in land surveying a lot. i’m the youngest in my department and i implement a lot but not all of these pointers to get the job done 👍🏼 if only they allowed drone surveying in my area (maryland, D.C). keep up the good videos!
Best of luck!
Thank you for this! Super cool video! A+++
Great Videos Rami, Keep up the educational material. Needed in all segments.
Rami thank you very much for your work
Excellent video, Thank You.
Really appreciative work to be connected and updated with advanced technologies.
👍👍
You rock!
thank you bro thank you
Hey Rami,
Have you used the IPhone Lidar to survey utility poles. I am curious how accurate you could get the length of a wood pole above ground and at what distance the iPhone starts to lose the ability to return points.
fwiw as a professional Land Surveyor in the UK I am very impressed by your ability to communicate. Is the next step to correctly colourise the geo-referenced point cloud (to resolve the mis-alignment between camera and LiDAR sensor) by geo-referencing the photogrammetry solution and then combining it with the LiDAR. This might be why the apps I have tried so far give you one or the other and not a single point cloud.
VOCÊ É O MELHOR
Cool👍🏻
Very informative, thank you Rami.
AFAIk the iphone 13's LIDAR scanner doesn't have the intensity feature, does the iPhone 14 comes with the intensity enabled?
Thanks for these informative videos. Which app do you recommend for building scanning with an iPhone 14 PRO
Cool job Rami! What will be the accuracy of the model? Can you use it for larger areas with bigger control points? Maybe if you can hold the iPhone 2-3 meters above your head? Greetings from Greece!!
I'm also curious about the answer to these questions!
Rami, thanks for the video! Is IPhone 14 Pro max compatible with vidoc?
Your all vedios are awesome ❤️
And voice quality in best❤️
Love from Bangladesh❤️
Hey Rami , is there a lidar sensor that i can buy to connect to an android phone
and if so , can you recommend on for me ?
all workеd
Hi did you make a traverse?
Can you make a video for using ipad in survey working and tell us if it really helpful
Hello
Thanks for your video ,
But you don,t have any check points ?
Thank you, very informative I will go purchase an iPhone 14 now
Glad it was helpful! You deserve this phone!
Hi Rami,
I am thinking to buy an iPhone 14pro to utilize the lydar in my drone projects. My question is if it's worth the money for the new gyro and accelerometers that it has over the iPhone 13pro
Hi, I made this project with an i13Pm and a drone, it is a factory, visible control points were marked, you can see the results here. th-cam.com/video/rYC3WnJBOY4/w-d-xo.html
Rami do you give live in-person classes?
Hi, which one is the camera sensor, which one do you cover up ?
Can you please explain to us how to use yusense ms600 multisepctra gimble to dji matrice 300 rtk throw dji pilot 2 application because when i check the type of camera inside the application I don't see this type of camera
What app i need to download?
what the file size of raw point cloud data from iphone 14?
Great job, once again! Please, advise me on the laptop brand, ram, processor, video specs you use…
I am using a Thinkpad X1 Yoga. It is my travel laptop and can handle cloud compare.
Great; thanks so much!
I experience that the cloud mirrors after tranformation, do U have any experience of that? If so, do you know what could be the cause?
What in your opinion is best ios app for scanning building interiors accurately with 12 pro max
Of the paid applications, Dot 3D is better. The program is able to optimize point clouds and correct shifts.
Made reasonably and conveniently. The perfect solution!
Look:
th-cam.com/video/oWB0kEoaGmA/w-d-xo.html
Samsung devices also have Lidar sensors
Can we use that too?
What coordinate system are you using for your control points?
Looks like state plane, I think he's in the Detroit MI area so EPSG 2253 is my guess
Doesnt the iPhone use a scattered light pattern of infrared red dots rather than lidar? So the reflectivity will not be optimised using the targets.
BUMP. Can I get more info from this? Because I wanted to know about this too.
I'm currently prototyping my own SLAM-LiDAR for mobile devices, and wanted to know the specs of iPhone's lidar if their intensity sensitivity is good for my purpose.
The targets have been unavailable on Amazon for a while. Has anyone found a good low-priced substitute? Also, I realize the target is made of reflective material, but would targets printed on plain paper give the same results with the iPhone?
wondering the same thing about paper targets. I have paper targets (~standard/A4 size) tht have been laminated, hoping they will be able to be used for georeferencing
Have you noticed any difference between the LiDAR sensors on the iPhone 13 and 14?
Yeah I’m here to question both this and it’s not like the LiDAR is different either is it? It’s been the same since introduced. This is just saying he’s got last weeks new phone!!! This will work on iPhone 12 Pro and beyond. You don’t need a 14.
@@computationalcinematographer , its because users search "iphone 14" much more frequently than "iphone 12/13" for now
@@staskozak8118 oh totally get that, but don’t give Apple more credit than they deserve! Keep up the great vids.
Finally a video where x coordinate is before the y 😋
Not by choice, it should be Northing (Y), Easting (X), Elevation (Z)
@@RamiTamimi wash your mouth out sir! This is blasphemy 🤣
Wow. Do you accept interns? Would love to learn a lot
is the radar on the 14 better than the 13
We'll have to find out, more testing coming soon
Plz tell me exporting format from IPhone sir
i exported in pts for this video
@@RamiTamimi sir I'd like to export RCP format. Plz tell me which in 3d scanner app.
Sir why u deleted that video on photogrammetery with iPhone, in which multiple photos are being collected!
It's still available.
Hi Rami. Is it possible that you didn't export the intensity values. When i export in PTS Format the Intensity Value is 0 for every captured point. After importing the data into cloud compare. The software uses the blue value as scalar field. Maybe you can check in your data. Did you use the 3D Scanner App in Lidar Advanced Mode, then processed and exported the data as PTS File?
Yes, I use it in advance mode, the light intensity is export with a PTS extension, I’m not sure if it comes out with other extension files. I didn’t realize that when I brought this into Autodesk recap as an LAS file the intensity values were all zero.
@@RamiTamimi Alright, thanks for the fast response. I wonder if it may happen because i use the iphone13 pro max. Can you test if you have intensity values when exporting in PTS with the iphone13?
The information would be very helpfull for me. I plan writing my bachelor thesis about a laserscanning comparison including i phone lidar data.
7:25 typo
The error is under 10 millimeters?
The error is about 30 millimeters.
@@RamiTamimi There was a tiny typo in the 1st ref point :) 1349407.77 instead of 13494077.77.
@@RamiTamimi yes it’s true. You did a typo by deleting the 7 at 7:12 in the video. I wonder what is the new accuracy now.
iPhone 14 Pro LiDAR is more accouracy than 13 model ?
Not sure yet, we will find out soon.
@@RamiTamimi thanks😉
Why do this like hard with expensive phone normal DSLR cameras can get more than accurate point LiDAR is not a good solution
You made a mistake with the first reference point coords yet your errors were good? Some background editing perhaps? 🤔
You got me, 77.77, for some reason the last 7 before the decimal got deleted. We caught the error when the alignment failed the first time, but you know, background editing hides my mistakes. 😄
@@RamiTamimi knew it! 😁
Can I say IPhone Pro is the cheapest Lidar Scanner devices ? 🤔
