Point-to-point distance (at the sweet spot)

The average distance between two neighboring points in the point cloud of a plane located in the focus distance of the camera. Alternatively, the square of the point size is the average surface sampled by a single 3D point on the plane scanned in the focus distance of the camera.

The point size linearly decreases with the distance. Therefore, it is possible to calculate the approximate point size using the optimal scanning distance (sweet spot) and the point-to-point distance (at the sweet spot) values, which can be found in the datasheet. If the point size (P _s
) is at the optimal scanning distance (D_o
), then we can calculate the approximate point size (P
) at the desired distance (D _d
) as follows:

P
= (P _s
/ D_o
) × D _d
