Best Scanning Practices
Walk through the property
Try to get a rough (or specific) idea of where you’ll be placing the camera, and the “path” the camera will take that will create the most seamless point cloud possible.
For precision, consider using tape or another type of “marker” to individually mark scan points on the floor.
Distance & Line of Sight
Place the camera 5 to 8 ft (1.5 to 2.5 m) from a previous scan.
The maximum distance can vary depending on the actual property.
The maximum distance may also be dependent on the device. Follow user manual guidelines.
Keep a clear line of sight to a previous scan.
Keep the camera 24 in (60 cm) away from walls and objects.
This will help avoid slices, warps, and distortion.
Scan before a door and after entering but not directly inside the threshold.
Scan in a clean, clear grid pattern for a professional look.
Specifically for photogrammetry devices:
Turn on all the lights in your property before scanning
Cameras will have a hard time scanning dark rooms - make sure every room is well lit, either from natural sources (open windows) or actual lights.
Keep in mind, certain lighting conditions will cause your tripod or camera to cast a shadow ahead of your viewfinder - if this happens, adjust the angle of the shot.
Try to avoid extreme light differences
Though the Pro and Pro2 cameras have HDR (which assists in balancing uneven lighting), it’s best to try to avoid extreme light differences when possible.
Example: A candle-lit bedroom, and an incandescent-lit bedroom.
Minimize direct sunlight
Direct sunlight can blow out the image and/or disrupt the image sensor - this will result in poor 3D geometry (otherwise known as “holes” in Floorplan or Dollhouse views).
Use 360° Views to compensate for excess light
If you must perform your 3D scan in direct sunlight, we recommend using 360° Views instead.
