Title: Exporting Dense Cloud as Points; No Point Confidence Field
Post by: Bolli on July 18, 2022, 03:36:21 PM

Hi All,

I'm exporting dense cloud points for viewing in another application. The other half of my workflow requires point confidence to be included in the exported PLY file. My exports from the GUI with the AIP generated dense cloud are just fine when I have all the boxes checked, but my exports from the API lack the required Point Confidence field in the PLY despite using the TRUE argument (below). The API exported PLYs look fine otherwise.

Code: [Select]

    chunk.buildDenseCloud(point_colors=True, point_confidence=True, keep_depth=True)
    doc.save()
    print(proj_name + " Dense Cloud built")

    #Export Local points
    if chunk.dense_cloud:
        chunk.exportPoints(export_path + '/' + proj_name + '.ply',
                           source_data = Metashape.DenseCloudData,
                           save_normals = True,
                           save_colors = True,
                           save_classes = True,
                           save_confidence = True)

Any advice on the this issue?

Hello Bolli,

Which Metashape version you are using?

I have tried to use your export code from the project with generated dense cloud with confidence values and the confidence is properly saved (dense cloud imported back to Metashape, for example, shows the confidence).

Hello Bolli,

Can you please check if the problem is resolved in the newly released 1.8.4 version: https://www.agisoft.com/downloads/installer/

Hi Alexey,
Thanks again for the support. The issue was in the other program I was using to view the point clouds and not with the agisoft generation at all. It ended up not knowing what to do with the classes field and failed on both the GUI generated PLY and the python generated PLY. All is good on our end with this issue.
Thanks,
Bolli
