NavVis VLX Quality Map Checklist

Prev Next

Before finishing a scan, check the quality map using the following checklist:

General scan quality checks

  • Trajectory continuity: Check the path is continuous; no visual breaks or sudden jumps in the quality map.

  • Overlap trajectories: Check that across rooms/hallways there is sufficient trajectory overlap.

  • Loop closures: Completed loops visibly connect; start/end paths meet cleanly.

  • Control points (if used): Placed and captured.

  • Coverage: All intended areas visited; no blind spots.

Panorama quality checks

  • Panorama icons are visible: Confirm (360° display on the quality mapthroughout the scanned area.

  • Sharpness: From the scanning screen, open each panorama and rotate or zoom to check for moving people or objects. Confirm there is no motion blur.

  • Even panorama distribution: Check that panoramas aren't clustered in one area with large gaps elsewhere; coverage should be reasonably consistent across the whole dataset.

  • Coverage: Confirm major junctions, thresholds, and key assets are represented on the map. Add supplemental panoramas where documentation value is high.

  • 360° panoramas placed where needed: If full 360° coverage was required (e.g. for specific deliverables), confirm 360° panoramic icons are present at those locations.

  • No panorama-free dead ends: Check that corridors or rooms that were scanned to the end and turned around still have a panorama captured before exiting.

  • Consistency: Panorama spacing roughly follows the plan; density increases only where complexity warrants it.

  • Point cloud will be colored: Since panoramas drive point cloud colorization, any area with no panorama icons will have an uncolored point cloud.
