Depth

The depth map is a video that represents distance to surfaces.

A value of 0 (black) means the surface is at 0 m; a value of 1 (white) represents 10 m. Currently, the maximum is 5 m, which matches the LiDAR range.

Confidence

The confidence map shows how reliable each depth value is.

Level of confidence by color:

Blue: High Green: Medium Red: Low

For example, you can use the blue channel as a mask to keep only high-confidence depth values.

How to use

Depth maps let you recover positions for things that can’t be scanned. For example, if you film a moving object or character, you can infer its position in space from the depth map.

In Nuke, you can use the DepthToPoints node to get a point cloud from the depth images and camera.

Important

Multiply the depth by 10 to match the scan scale.
