Scope

Troubleshooting procedure

Root cause

• Not enough valid images in the post-processing stage.

• Colorize point clouds option was not selected in the processing setting.

1 Check in the datasets_rec/2021-xx-xx/cam folder

• If there are enough images that correspond to the numbering of info files under datasets_proc/2021-xx-xx/info.

• If there are not enough cam images, then the point cloud coloring stage will not have enough data to execute the colorization process.

2 Check Colorize point clouds

Check if the Colorize point clouds option was selected in SiteMaker or the Colorized option in cloud processing configurations.

3 Check which point cloud

Check which point cloud you're using:

• Datasets_proc/2021-08-21_15.56.33/pointcloud.e57 or pointcloud.ply -> should have color usually

• 2021-08-21_15.56.33/pointclouds/pointcloud-raw.e57 or pointcloud-raw.ply -> does not contain color information
