1
Depends on ambient light, which can act as a source of noise. Bright sunshine may
shorten the actual range of the scanner to lesser distances.
2
Ranging error is defined as the maximum error in the distance measured by the scanner
from its origin point to a point on a planar target.
3
Ranging noise is defined as standard deviation of values about the best-fit plane.
4
A noise-compression algorithm may be activated to average points in sets of four or sixteen, thereby
compressing raw data noise by a factor of 2 or 4.
