Python and Java API / Creating XYZ maps for each pixel of an image
« on: March 01, 2023, 07:25:00 PM »
Hi, I am looking for an efficient way to export XYZ maps for each image. Metashape can export depth maps that are camera-model distance projections for each pixel in the image, and I need this for the XYZ information.
Alternatively, can the Metashape python API convert a depth map into an XYZ point cloud? Third-party modules like open3d can do this in camera-relative xyz space for a pinhole camera, but I need this in the model's global XYZ space while accounting for camera distortion.

This question is similar to the following threads, but it doesn't look like they fully resolved the need.
