Scanning mirror and glass surfaces (mirrored sliding-door wardrobe)
Mirrors and glass are challenging for LiDAR because light is reflected or passes straight through. A sliding-door wardrobe with mirrors is a typical example that easily causes errors in the model.
How to scan a mirror/glass wardrobe
- Open the wardrobe doors and slide them towards the middle.
- Start in one corner of the room.
- Scan around the room without scanning straight at the mirror or glass surface.
- Finish in the other corner.
If you scan straight at the mirror, the surface is often read from floor to ceiling as a doorway, and you get a «gap» in the model.
Note: The same applies to large window surfaces and shiny surfaces. Avoid scanning directly at them, and supplement with photos and manual measurements if needed.
