Remarks

The "height" of a range image pixel relative to a base plane is defined as the signed distance from the center of the range image pixel to the nearest point on the base plane, measured in selected space 3D coordinates.

The user can specify a minimum height threshold so that pixels with a small height (e.g. noise about the base plane) can be excluded from the volume computation. Only pixels with a positive height that is greater than or equal to the user-specified minimum height threshold contribute to the computed volume.

Note that height threshold does not affect the amount a pixel used in the computation contributes to the volume. The height threshold only determines whether or not a range image pixel is used.
