Setup3D
coordinate system
- Reference - select a 3D reference for position
and results
ROI
- X,Y,Z position
- Center - ROI box center
- Size - ROI box dimensions
- X,Y,Z angle - ROI box rotation
Point cloud decimation (x & y)
- Factor - keep only every nth sample in x and y
directions
Point cloud filter
- Contrast - element 4 in a 5-element point cloud; set min and
max allowable value
Constraints
The plane fit can run a two-pass fit procedure. The first option is used
to turn this on or off.
- Ignore points further from plane than - if activated, points
further from the initially fitted plane will be ignored in the second
pass. If not activated, only a single pass is run, using all points
within the ROI.
- Max fit RMS for accept - RMS filter to accept/decline the
result
- Min fit percent for accept - fit percent filter to
accept/decline the result (only effective if two-pass is run)
- Min number of points for accept - point count filter to
accept/decline the result (only effective if two-pass is run)

Remarks
Plane
A plane is given by the equation ax + by + cz + d = 0. The constants
a, b, c and d are given as the results Plane.x, Plane.y, Plane.z resp.
Plane.w
NormalLine
The plane normal is a unit length line with its point p
located at the center of gravity for all points used to fit the plane
(of course projected down on the plane). The vector v points
perpendicular to the plane.
