Spatial Subsampling -SS not copying Image Pose Information
Posted: Mon Oct 28, 2024 8:09 am
Using Alpha 2.14 (Oct 14 2024)
When Spatial subsampling a point cloud, the image pose information is not copied (the images are), so the resultant exported scan images are not recognised in other software.
How to replicate:
1) import E57 with images
2) spatial subsample scan (any density)
3) export scan as .e57
4) reimport exported scan (into cloud compare or into E57 inspector)
5) compare the folder structure of the original (not SS) to the new (SS) scan
6) key differences are that the image pose information is missing (there might be other differences)
When comparing the two scans folder structure, there is no pose information copied for each of the cube face image. When then importing the output into the cyclone register, faro scene, e57 inspector or any engineering package i have tried so far, the E57 no longer imports with images in the right location with the scan.
The two attached images show the original scan folder structure with image pose information (Top) and the new folder structure of a scan, which was exported as e57 and then reimported into cloud compare (bottom).
If you need any other information, please let me know, I can also provide samples.
Thanks!
