Evaluate scanning problems on your site
Devices can recognize objects in the environment within a 30-foot radius, however, there may be areas or items within the recognition radius that your device cannot scan or recognize. See the following workarounds.
Problem areas for scanning
| Problem area | Workaround |
|---|---|
| Very bright lights or very dark shadows | Before 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? | Avoid scanning mirrors or shiny metals. Avoid pointing the camera at these surfaces if they are within the recognition radius, especially while you're moving. |
| Highly waxed floors | Place non-reflective objects, such as cardboard, cones, or pieces of equipment, on highly waxed floors. |
Visually complex, repetitive areas like patches of grass Why is this a problem? | 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 sun | Set up something overhead, such as a tarp, to provide shade. Alternatively, avoid using these areas for alignment. |
Inadequately scanned or empty areas can cause a model to drift out of alignment. For causes and workarounds, see Fix scan related model drift.
