Scanning instructions :

• Set up your scene and lighting before shooting. Do not move furniture or doors, or turn lights off or on once you have started taking pictures.

• Our algorithm depends on significant visual overlap between the images. That means:

• • Take panoramas 1.5 meters / 5 feet apart. In larger rooms you can take pictures further apart, but ideally take at least 6 pictures per room.
  • When entering another room, always take a photo just before the doorway, one in the doorway and one just after the doorway, with ~10cm distance in between.
  • When shooting on stairs, take a shot on every stair step.
  • When shooting in narrow corridors or stairs, decrease the distance between photos to 0.5 meters / 1.5 feet. Do not take all shots in a straight line. Instead, take a step to the side (by ~30cm / 1 foot) every 3 shots. That way, visual features can be triangulated better.
  • In corners that join two corridors, take not 1, but 2 shots at ~30cm / 1 foot offset. Both shots must be able to look down both corridors.
  • You must follow these instructions, otherwise your scan will likely be incomplete.
