General / Re: ArchiCAD terrain profile

« Last post by Magictor24 on May 01, 2026, 11:42:00 AM »

Thank you for your reply Olihar.
I tried instead with a 3DS export but my project has no level in ArchiCAD.
I placed a terrain and the 3DS file next to it, but it is impossible to align it to the level of the terrain I drew in ArchiCAD



In plan view in ArchiCAD, we can clearly see that the project is not in normal view



Otherwise, I've put some reference points to maybe level it, but I have no idea at all how to adjust it



Thank you very much

Hello engfi,

I can see that you could enable only cameras you want to generate panorama and then generate a planar Ortho mosaic of these cameras using 3 markers on a plane parallel to one of the relevant camera's focal plane.

In example, I generated a planar ortho for only the right looking caneras for a 4-camera rig moving along the tunnel axis.

You could also consider generating Ortho with cylindrical projection...

General / Tunnel linear panoramic images from Lidar + imaging

« Last post by engfi on April 30, 2026, 09:44:07 PM »

Hi all,

Till now, i often use metashape (v.1.7.3) to produce orthomosaic from aerial nadiral images (aligning images, setting gcps, building dense point cloud, mesh and orthomosaic).

but now I would like to make a step forward, with tunnel acquisition by a mobile mapping system

i have:

- georeferenced tunnel dense point cloud (.las/.E57);
- georeferenced tunnel images taken by synchronized cameras, which take photos at a constant step (i.e. @1m), each framing a portion of the surface (arranged in a radial pattern to frame the entire tunnel, capturing images almost orthogonally to its surface).

What I would like to do is to create a 2D photo plan (linear panorama image, i don't know how to define it) for each camera that combines all the shots from that camera in a single "long" image. so that the final product is a single (real sized) long image for each camera.
The single images are undistorted (in .jpeg format); i also know the reference parameter for each image; i don't want a wonky orthomosaic projected onto a mesh, i would like to ""simply"" merge all those undistroted shots in a single 2d linear long panorama for each cameras

the final goal is to find structural defects and deterioration (and, possibly, be able to 2D/3D georeference them

(attached an example of some georeferenced and aligned shots taken by one of those cameras along the tunnel trajectory with 1m step)

Any suggestions for success are welcome, I hope we can start a good debate on this matte

thanks in advance, in the meantime I'll continue with my attempts

Hello Paul,

Thank you for reporting the problem. It will be fixed in 2.3.2 update. Meanwhile, if required, you can manually add proper values for Height and Width keys in the obtained dictionary.

Again why not transcode the files?

Which Codecs - Good Question (i am no expert).
It should be H.265 from the camera.
VLC Media Player is working, Windows Media Player isn't working.

Hello LWR,

Which codec is used for those videos?

Are you able to open such videos by default Windows video players, like Media Player, Movies & TV or Windows Media Player Legacy?

We are not yet able to reproduce the problem on NVIDIA RTX PRO desktop graphic cards.

But I saw that there is a new driver released: R595 U4 (596.36).

If anyone with the problem could check, it please let us know, if the problem is still there with the new NVIDIA driver installed. If the issue persists, please also try two things for additional diagnostics:
1. try running Metashape in DirectX compatibility mode from cmd.exe: metashape.exe --opengl angle
2. try running Metashape with administrator privileges.
If either option allows to get rid of the visualization issue, please also report here.

General / Calibration.todict() method

« Last post by Paulo on April 29, 2026, 11:30:22 AM »

Hello support,

with latest release we have the new Calibration.todict() method that creates a dictionary of calibration parameters according to given Metashape.CalibrationFormat argument.

I have noticed that for a given sensor with following Metashape calibration parameters:

Code: [Select]

Calibration interna: {'f': 4241.725572564694, 'cx': -19.744119513936447, 'cy': 25.30570870270943, 'k1': -0.04742383277638246, 'k2': 0.009341131199137442, 'k3': -0.0818087829741068, 'p1': -0.002427327074582477, 'p2': 0.0024229055174815107, 'width': 4243, 'height': 2828, 'pixel_height': 0.00848517808414172, 'pixel_width': 0.00848517808414172}
then all dictionaries generated with this method, gives Height and Width always equal to None which is clearly not correct:
