[SOLVED] Building dense cloud at high quality returns "problem"

[talldrinks]

Morning (or evening),

I've got a basic script like this:

Code: [Select]

print("===Match Photos===")
chunk.matchPhotos(accuracy=PhotoScan.HighAccuracy, preselection=PhotoScan.NoPreselection, filter_mask=True, keypoint_limit=30000, tiepoint_limit=30000)

print("===Align Cameras===")
chunk.alignCameras()

print("===Export Cameras===")
chunk.exportCameras(path+"/Scan Mesh/Cameras.xml")

print("===Build Dense Cloud===")
chunk.buildDenseCloud(quality=PhotoScan.HighQuality, filter=PhotoScan.AggressiveFiltering, keep_depth=True, reuse_depth=False)

print("===Build Model===")
chunk.buildModel(surface=PhotoScan.Arbitrary, interpolation=PhotoScan.EnabledInterpolation, face_count=500000)

print("===Build UVs===")
chunk.buildUV(mapping=PhotoScan.GenericMapping)
...

This fails to build the dense cloud step, and throws the error: "problem".

output:

If I manually build high quality point cloud in the GUI, it works fine.

Is this a strange memory issue somehow?

thanks.

Correction, it fails to build dense cloud at any quality level via this script.

I figured it out. My mistake.
The bounding volume region was being set far too small in some of my test scenes, so there was zero volume. This error displays as "error: zero volume" during GUI build, but "problem" displays during a scripted build.
