Hello bassistas,
Is it possible to share any small scan example with 1/1 and 1/2 resolution to support@agisoft.com, so that we could check it on our side?
I figured out how to fix this. I had to compute the chunk transform that would ensure that the laser scans are in the correct position. To do this prior to alignment I duplicated the chunk, and then aligned the original chunk. From there I had to use the python console.Code: [Select]# gets chunks to use
non_aligned_chunk = Metashape.app.document.chunks[1]
aligned_chunk = Metashape.app.document.chunks[0]
# function to get camera based on label
def get_camera(chunk,label):
for camera in chunk.cameras:
if camera.label == label:
return camera
return None
# gets a spherical from a laser scan for both chunks
non_aligned_camera = get_camera(non_aligned_chunk, "Scan_001")
aligned_camera = get_camera(aligned_chunk, "Scan_001")
# non aligned camera is in the correct position so we work out chunk transform to equal non aligned camera position
aligned_chunk.transform.matrix = non_aligned_camera.transform * aligned_camera.transform.inv()
From reading this and the knowledge base entry I'm still not clear on exactly what effect this procedure will have on the transforms of the Laser Scans. Will the grouped and fixed laser scans maintain their position relative to each other while the entire group is still allowed to move?
Dear Jed,
Yes, the grouped and fixed laser scans will maintain their position relative to each other while the entire group is still allowed to move.
Can the entire group be locked in to place easily so that it is not allowed to move? That's something we've been asking for ever since laser scan support was introduced, e.g. this comment in the 1.7.0 prerelease thread:
https://www.agisoft.com/forum/index.php?topic=12653.msg56372#msg56372
Dear Jed,
Currently alignment with preserving absolute transform is not supported. However, even after resetting alignment for fixed laser scan group the relative orientations will be preserved and group as a rigid structure will be aligned to photogrammetric tie points.
Hello bassistas,
You have Assertion 23671468921001171 in the log, it is a different one.
Can you confirm, if you are working with the newly created project or using some old one? This assertion could be related to rare cases, when the project has been created with the laser scans added in some 2.0.0 version pre-releases.
Its not resolved, I still get the Assertion failed error in 2.0.2
Hello bassistas,
Can you share the complete log from 2.0.2 related to the failure? Either post it here or send to support@agisoft.com.
Hello bassistas,
Do you mean loading to laser scans to Metashape or uploading them to Sketchfab?
Can you share the log related to the operation, including Metashape starting lines?
Dear bassistas,
It would be helpful, if you can share the sample data (your E57 file).
If you are able to share the data, please send the download link to support@agisoft.com
Hello bassistas,
Do you use Import Depth Images or Import Point Cloud for E57 files? Also can you share the processing log related to the file import (enable Write Log to File option in the General Preferences tab and try to reproduce the issue)?
I'm using the import point cloud option for the E57 files. Here is my log file, I don't see any errors, it just crashes:
