Object in shade, sky overcast. Beam interruptions, severe heat shimmer and
moving objects within the beam path can result in deviations of the specified
range noise and accuracy.
* Range noise describes the standard deviation of the scan points
residuals to the modelled surface:
•
Plane surface target
•
Perpendicular orientation of the plane target to the measure-
ment direction
•
Modelled plane best fitted into the point cloud
The absolute position accuracy of a modelled surface is similar to an RL single
measurement:
