Import ASCII Pts (as laser-like scan)

[kb2zuz]

We have been using a GOM/Zeiss structured light scanner to supplement some of our photogrammetry. It can export points as ASCII .asc files. I have had some success converting these .asc files to .e57 files via CloudCompare and importing them into Metashape, but it would save a lot of additional work if Metashape could natively import .asc point clouds.

Just a note we are using metashape for making models of objects, not geography/topography. I also know these are structured light scans and not technically laser scans but it is useful particularly when we have objects with heavy occlusions or materials that do not work as well for photogrammetry (flat areas in a solid color with little detail for photogrammetry to latch on to).

If we could import these files directly it would substantially improve our workflow.

Hello kb2zuz,

Can you share a few lines as an example of the data format?
