Feature Requests / Import ASCII Pts (as laser-like scan)

« on: July 19, 2024, 07:03:50 PM »

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.

General / Decimated Model not aligned to original

« on: November 17, 2023, 08:42:52 PM »

I produced a model after aligning multiple laser scans to supliment the photogrammetry. I selected the resulting model (with an [R] alignment designation) and decimated it to create a 2nd smaller model. The resulting decimated model is tilted at an angle and not aligned to any other model or point cloud in the project (even in other chunks). This of course makes it impossible to build new textures from the images.

Bug Reports / Refine Mesh: Kernel Failed: invalid argument (1) at line 99

« on: November 08, 2023, 06:14:48 PM »

I am trying to refine a mesh. I ran it with the settings of Ultra High, 10 (also previously tried iterations, and 0.5 smoothness

The project has 126 aligned images but disabled 40 of them and am trying to only run on 86 images that were cross polarized and not the 40 that were not polarized. All images are 50MP (8272x6200 and 16 bit/channel TIFFS).

Here's a copy and paste from the console:
