Dynamic Object Filtering

People or objects moving nearby while mapping is in progress can cause artifacts to be generated in the Point cloud data. Dynamic object filtering removes these artifacts and uses information from other scans to remove fringes. This results in cleaner point cloud data.

Dynamic Objects Visible	Dynamic Objects Filtered Out

Dynamic object filtering is enabled by default during post-processing. In addition, thin structures are more likely to be retained than with our previous dynamic object removal algorithm.

Note: Dynamic object filtering is set by default to balanced mode. To achieve results similar to our previous dynamic object filtering algorithm, set the filtering mode to aggressive mode.

If dynamic objects or very fine or reflective structures are removed when they should be kept, disable dynamic object filtering using the disabled option:

• On the command line:

  navvis-postprocessing.sh --dynamic-objects-filter-mode=disabled \
    --proc-base-dir=/PathToProject/datasets_proc /PathToProject/datasets_rec/*

• In SiteMaker, add the following to the customs arguments field.

  --dynamic-objects-filter-mode=disabled
