5.1.4 “Plane Alignment” measuring program
Use the “Plane Alignment” program to align a point cloud. This step allows to compensate for changes to
the pitch the object in different measurements. Therefore, ROIs that are used in subsequent measuring
programs are not affected by the pitch changes and can be used at defined positions relative to the ob-
ject.
The object is rotated about a selectable rotation point so that the reference plane is equal to the xy plane.
Additionally, the position of the object may be compensated. By this the object will be translated so that
the rotation point is equal to the center of the coordinate system.
Note: In addition to the input point cloud, the “Plane Alignment” measuring program requires a reference
plane and a rotation point as input data. These objects have to be computed with the “Plane fit” measur-
ing program (see Chap.
6.1.3 ) which has to be in a previous program group. Alternatively you may use
another measuring program for computation of the rotation point (see below, Section 1).
Proceed as follows:
-
First, if you have not already, activate the “Evaluation” view (see Chap. 6 ), insert the “Plane fit”
measuring program and configure the measuring program in order to obtain a reference plane and
a rotation point (see Chap.
6.1.3 ). Alternatively you may use another measuring program for com-
putation of the rotation point (see below, Section 1).
-
Now, create a new program group (see Chap. 3.15 ) and insert the “Plane Alignment” program in
the “Data preprocessing” section.
-
Select the input point cloud, the reference plane and the rotation point for the program (see below,
section “1” and Chap.
3.16.3 ).
-
If required, activate the position correction of the object in addition to the pitch correction (see be-
low, section “2”).
