6.1.3 “Plane Fit” Measuring Program
Use the “Plane Fit” program to calculate a plane at 3D points. Proceed as follows:
-
If applicable, select the input data for the program (see below, section “1” and Chap. 3.16.3 ).
-
If necessary, limit the range for the plane calculation in order to eliminate interfering points (see
section “E” and Chap.
3.16.4 , 3.16.5 and 3.16.6 ).
-
If required, activate the optimized fit and enter a suitable threshold for the optimized fit (see below,
section “2”).
-
If applicable, select measured values that are to be used later for calculation, OK/nOK assessment,
logging and output (see below, section “H” and Chap.
3.16.8 ).
The measuring program outputs the following measured values:
-
Angle to x axis: The angle of the calculated plane with respect to the X axis.
-
Angle to y axis: The angle of the calculated plane with respect to the Y axis.
-
Angle to z axis: The angle of the calculated plane with respect to the Z axis.
-
Distance to origin: The distance between the plane and the origin of the coordinate system.
-
Center of gravity x: The X coordinate of the center of gravity of the points that were used to calcu-
late the plane.
-
Center of gravity y: The Y coordinate of the center of gravity of the points that were used to calcu-
late the plane.
-
Center of gravity z: The Z coordinate of the center of gravity of the points that were used to calcu-
late the plane.
-
Number of points: The number of points in the point cloud that were used to calculate the plane.
-
Sigma: The standard deviation of the distances between the points that were used to calculate the
plane and the calculated plane.
-
Peak to Valley (PV): The distance between the highest and lowest point relative to the calculated
plane. The highest and lowest point is determined from the points that were used to calculate the
plane.

Display Elements and Parameters in the “Plane Fit” Program:
A “General” toolbar: Using this toolbar, you can select the data source (see Chapter 3.4 und 3.5 ),
save and load parameters and reset selected parameters to default settings (see Chapter 3.17 ).
B List of active measuring programs: This section displays the active measuring programs from
the “Find objects” and “Combine objects” groups. You can add and remove measuring pro-
grams/measuring program groups (see Chap.
3.13 and 3.15 ), move measuring programs (see
