Thanks for posting this. Super helpful for those of us trying to figure it out. Edit, never mind I see this question was already answered... Could you add, how many photos this project has, how long it took and what your computer specs are? That would give us an idea of what to expect with our computers or what we need to get the processing times down. Thanks!
@@SkySurvInc Thanks for your fast response, I will do that, and hopefully pass useful stuff to you and your viewers too, exciting stuff after I master the initial learning curve, cheers.
This video is a few years old but figured i would try to ask anyways. Just learning metashape - coming from Pix4d and dronedeploy. Got a ways to go! But I am having issues with gcp accuracy in Metashape. We've processed the same map using 7 gcps in both dronedeploy and Metashape and in DD we are achieving .057' vs Metashape .332' . Undoubtedly there is something we are doing wrong and was hoping for some direction.
Hello @MrDennisrsjr, I have been trying to make ends meet with Agisoft Metashape. I find that it takes ages to generate dense point Cloud. Are you still using Agisoft Metashape, or have you found another 3D application? If so, what are you using now?
Still using Metashape! It is by far the best we have found (for us). It affords a lot more flexibility and the outputs are great. Curious, what kind of machine are you running it on and what are the specs? @@octaviodasilva9780
Hello.... I found the metashape video very good ... Do you have videos of point cloud filters and processing with metashape ... ???? thanks for your answer...!!!!
Very helpful! I have switched from Pix4D to Agisoft and this was awesome! Question, how to I export the "filtered dense cloud"? When I filtered by confidence, then export it out to bring into Lidar360, all the original points are still there. Thanks for any help and gain thank you for the very helpful videos on Agisoft.
I meant to add, I had alot of water which the filter helped clean up. I then just used the freeform selection tool to select all the rogue points and delete them. After that I exported thinking the file would be the "filtered and cleaned" version but it was not.
@@flyinlo1474 you have to assign a point class, like ground. Then you can export that class only. Alternatively you can filter the inverse(only the “bad” points) then delete them!
Thank you for your tutorial. Could you post your machine specs here? I'm trying to optimize a local machine for Metashape and your machine seems to be a good starting point.
@@SkySurvInc Thanks for the specs, really helpful for us too judge our own machines or the ones we need to buy / build. Those specs are almost identical to mine from the computer I built in 2014. Like you said it was a hot rod back then... With that machine how long did this project take and how many photos did it have? Thanks!
Nice video, very helpful! But I have a question, what if we don't convert the references at the beginning of the process? Would it affect the entire process after that?
Thank you for the good content. I take a photo with a drone and then create 3d data with metashpae The question is I don't know how many photos for usable quality.(like animation clip for presentation) For example, how many photos are suitable for an area of 100m x 100m? In the video, 64 photos, but in my case I'm working with over 300 photos in a similar area. Of course, the work time is longer. It's my problem. I would like to hear some advice on how to reduce working time. Please advise thanks..
First of all, thank you for the advice. In my last project, I photographed a road about 100m x 150m at a height of 35m and the number of pictures was about 800 or more. And, The dense cloud process took about 20 hours and as a result the quality was good(3d data). My concern is how to get satisfactory 3d data with few photos. Do you have any advice?
@@reluxopenclass4331 It seems like you have excessive overlap. On s site of that size, the most photos I would take is ~200. I would recommend a max 90% side/overlap. 80/80 should work for most situations. If needed, you can decrease this even further(70/70) for flat areas(like your road). Bottom line, there is no absolute rule for this, as every site is different. Hopefully this is helpful.
Yes, when shooting with a drone, the camera will automatically set and shoot. and It's the good quality, but the number of pictures was always too heavy, I thought. Thank you for your advice on reducing the number from 80 to 90 photos.
Hello, i followed all your instructions step by step but my Dense Cloud is way worse than yours. Any ideas what went wrong ?

just started using metashape, like your stuff sub

Great video, thanks.
Thanks for taking a look. Let me know if you have any questions along the way!
Fantástico el video...!!!!!
Por favor podes hacer otro igual con otro ejemplo.....
Gracias 😊

Great video, il helps me a lot! If you have made a video to explain how to make contours lines and how export them, I’m really interrested.
Good work. Thanks.

Did you update and optimize after you matched the GCPs?

The difference between the value ALTITUDE 181.56m, Altitude 595.69 Is this difference in altitude real, that is, the value 595.69 represents what?
thanks , but what kind of output format r there !
can we use the model in REVIT or e57 format
Many outputs available under export - for point clouds, DEMs and TINs!
Nice video, very helpful! But I have a question, what if we don't convert the references at the beginning of the process? Would it affect the entire process after that?
If you don't convert, your coordinates will be in WGS84 Lat/Long. If you're OK with that, then no problem!
Is it tolerable if I use handheld GPS garmin device to get the GCP?.
It’s not possible to improve the positioning with a handheld GPS
Is it ok if I don't have GCP data and just proceed with the next step?. I'm aware that my accuracy might be off few meters.
Thanks in advance.
Yes, you can skip that step.

Hello, Best thing to consider is your target GSD for the end result. YOu can work back from there to determine a flying height, overlap and sidelap.

Is there any benefit of turning Adaptive camera modelling on with DJI cameras?
from what I understand, Adaptive camera modeling SHOULD be used with non calibrated cameras(DJI)
hi its very nice video.
but how did you switch from perspective to orthograpic screen ?
The Model Tab > View Mode > Select the Ortho/Perspective mode option. Alternatively, you can press the 5 key on your keyboard.
@@SkySurvInc THAKS VERY MUCH
Does this process work with the local coordinates option?
Sure, why not?!
@@kellyness7915 I suppose the additional step is you would have to unselect the cameras before optimizing and building dense cloud.
@@phoreal22 correct, in the registration tab.
can I send you an area for you to execute this command?
Sure. skysurvllc@gmail.com
IMPORTED ONLY 6 POINTS, MY FILE HAS 500 PHOTOS
6 GCPs? How many did you have? I suggest adjusting the tolerance and maximum residual.
I Will try to adjust the tolerance, thank you
DETECT MARKERS
MAKES MANY POINTS, CAN YOU TELL ME WHY?
700 POINTS
I think you should adjust your your tolorance and maximum residual.
See above comment. Adjust your tolerance and maximum residual.

Nevermind, i had to open the Dense Cloud from the Workspace Menu.
Stand back a bit from your mic. Too bassy.
Thanks for the feedback. Otherwise, did you find the video useful?
