Python and Java API / Re: cam.project, cam.calibration.project and cam.sensor.calibration.project

« Last post by pts_and_clouds on Today at 10:34:57 AM »

cam.project seems to be the recommended way now (see the last response from Alexey in the thread below), but doesn't seem to work here for some reason.

Python and Java API / cam.project, cam.calibration.project and cam.sensor.calibration.project

« Last post by pts_and_clouds on Today at 10:25:39 AM »

Are these three commands supposed to produce the same output, i.e. the 2D projection of a 3D point on an image?

I am getting the same output for cam.calibration.project and cam.sensor.calibration.project, but cam.sensor returns empty for the same exact point.

In [25]: cam.project(temp_b[0])

In [26]: cam.calibration.project(temp_b[0])
Out[26]: 2022-11-30 12:53:57 Vector([226.91737982171833, 3066.876461424863])

In [27]: cam.sensor.calibration.project(temp_b[0])
Out[27]: 2022-11-30 12:54:04 Vector([226.91737982171833, 3066.876461424863])

Thanks in advance for your help.

General / The buildings in the 3d model are not clear and contain distortions

« Last post by Majdoleen Awadallah on Today at 09:50:30 AM »

Hi All,

After we generated the tiled model from depth maps, we found that their is a distortion in the 3d model and the buildings are not clear as seen in the photos, May you please tell me how to solve this issue to get better result?
P.S: The total area is around 12000 donums, total images (7800) and the required gsd is 3cm

DO you have any manual or video that may help showing how to edit the mesh?

General / Re: Agisoft and opencv calibration.

« Last post by frenezulo on Today at 09:21:51 AM »

Helo Paulo,
thank you for your reply and clarification.
Do you know, why is f=fy in Agisoft? And why is b1 defined in this way?

My final application is to use camera calibration intrinsics from Matlab in Agisoft and because there is no direct import of these parameters from Matlab, I started to look into various definitions of intrinsics in different softwares and it seems there are quite a differences despite the same notation.
Based on Agisoft Manual (https://www.agisoft.com/pdf/metashape-pro_1_8_en.pdf) and Matlab documentation for camera calibration (https://www.mathworks.com/help/vision/ref/estimatecameraparameters.html) it seems that p1 and p2 coefficients are inverted. Is my understanding correct?

Thank you
Tomas

Python and Java API / Export profile of shapes using script

« Last post by Corensia on Today at 08:35:39 AM »

Hi,

Using the GUI, it's possible to select a line shape, right click and 'Measure', and finally click the 'Profile' tab to see the profile of the line. Additionally, you can save the profile as a shapefile.
Is this task possible using python scripting? Im having trouble finding it in the python API guide.

Any help/tips would be appreciated. Thank you!

David

General / Re: network parallel processing

« Last post by jetdog6 on Today at 02:00:57 AM »

It looks like if I run multiple nodes on one computer (metashape.exe --node --dispatch 10.0.48.142 --root "\\dowl.com\FWE-Projects\Reno\Survey\Aerial Processing\Agisoft Metashape"), I can run jobs simultaneously.  Can anyone see a reason this will be a problem?

General / Re: Assign the proper camera location and orientation to the single image

« Last post by alobo on November 29, 2022, 08:42:42 PM »

Thanks, excellent, it works very well. We've been able to create a shape file with this information to locate the original photograms on the mosaic.
I suggest Metashape produce this information as a regular output, it is very useful. If you do, please save the Z agl that is estimated by Metashape for each photogram
(height = photo.sensor.height I guess).

Hola frenezulo,

in Agisoft camera calibration format:
f = fy
b1 = fx - fy or b1 + f = fx.

As for inverting tangential distorsion it is certainly possible as it is the same for Pix4d calibration vs Agisoft. Maybe support can confirm,

Hope this helps,

General / Cloud Server

« Last post by sfrederickson on November 29, 2022, 05:51:53 PM »

Hi there,

I was wondering if anyone had any experience or knowledge regarding running Agisoft Metashape in a cloud.

I am currently working on a project with ~4TB of images and running processes on our machines  has taken weeks.

Would running this on a server make the process go faster?
