Evaluate scanning problems on your site

Your device may not be able to scan or recognize some items or areas in your site effectively. Many scanning and recognition problems have workarounds.

Notes:

  • Devices with LiDAR can recognize objects in the environment within a 30-foot radius.
  • Devices without LiDAR can recognize objects within a 5- to 10-foot radius.

Problem areas for scanning

Problem areaWorkaround
Very bright lights or very dark shadowsBefore scanning the environment, walk through the area and adjust the lighting. If you can’t change the lighting, avoid having bright lights or dark shadows within the recognition radius on screen.

Mirrors or shiny metals

Why is this a problem?
Mirrors or shiny metals cannot be scanned. Light reflected back to the camera can affect a larger area in the scan.

Avoid scanning mirrors or shiny metals. Avoid pointing the camera at these surfaces if they are within the recognition radius, especially while you are moving.
Highly waxed floorsYou can add non-reflective objects, such as cardboard, cones or pieces of equipment, to a highly waxed floor.

Visually complex, repetitive areas like patches of grass

Why is this a problem?
Can cause part of the image to move as you move (“wormhole effect”).

Avoid pointing the camera at these areas, when aligning the model. Avoid using these areas for alignment.
Outdoor areas without overhead structures to block the sunSet up something overhead to provide some shade (a tarp will do) or avoid using these areas for alignment.

Clutter (Devices without LiDAR)

Why is this problem? May produce holes in the scan mesh because the device cannot recognize the objects in the clutter.

If possible, remove the clutter.

Inadequately scanned or empty areas can cause a model to drift out of alignment. For causes and workarounds, see Fix scan related model drift.
