General / Re: Convert camera coordinates to world coordinates
« on: August 28, 2021, 11:49:45 AM »
Thanks Bzuco! I managed to transform rotation matrix from Metashape to Euler angles but these seem to be not very optimal solution because of possible Gimbal Lock (for example two cameras very close to each other have very different XYZ rotation angles, but still very similar overall angle). That's why it's probably better to keep all values in matrix.

I'm not sure about one more thing whether camera rotation matrix from cameras.xml is already in world coordinates or if I should multiply it by chunk transform (in Metashape Standard). @Alexey, could you confrim this?

General / Convert camera coordinates to world coordinates

I'm using Metashape Standard and I would like to convert all cameras coordinates calculated from alignment to world coordinates. I can extract 4x4 camera transform matrix from xml file (Export Cameras option) but I'm not sure how to do the conversion. I don't know where I can find world orientation in Metashape Standard. Is it possible?

Thank you Alexey for very fast replies and solving this problem.

Bug Reports / 1.7.1 Holes in mesh
« on: February 11, 2021, 02:22:55 PM »
Hi everyone!

I found out that new version of Metashape generates weird holes in mesh. Case is very simple: black turntable and background, camera in one position and photo every constant angle.
Also I used old depth maps generating method (from 1.6X) by setting
Code: [Select]
BuildDepthMaps/pm_enable to False and it's not generating any holes so it seems that new method is broken somehow.

Could you tell me what might be the cause of that problem? This is very simple example, but it's very annoying on more complicated models.
