Setup
3D coordinate system
- Reference - select the 3D calibration tool that
describes your camera.
Constraints
- Ignore points further from plane than - if
selected, a second pass is run to fit the plane better,
with outliers removed
- Max Fit RMS for accept - the mean error from
the points used in fitting the plane
Plane origin and direction
The origin of the resulting reference system and the
direction of the X axis is calculated from two points (after
projecting these points onto the plane). The first point
sets the origin, and the direction from this to the second
point will be the X axis.
- Calculate from first two active points - use
the first two active points, whether filtered as
outliers or not
- Calculate from first two accepted points -
use the first two points actually used in the plane fit
- Calculate from explicit points - specify
points in space explicitly
Axis size - defines the length of the 3D axis visualisation
3D Points
At least 3 points must be active for the mapping to
function. Select 3D points that are (nearly) coplanar to
create a new 2/3D reference system based on this 3D plane.
(If 3 non-collinear points are used, the fit is perfect.)
- Tool - tool delivering a 3D point (x, y and z)
- Result - tool result to use
