6.1.5 "Cylinder Fit" Measuring Program

Use the "Cylinder Fit" program to calculate a cylinder 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 cylinder calculation in order to eliminate interfering points (see
section "E" and Chap. 3.16.4,
-
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/y plane: The angle of the longitudinal axis of the calculated cylinder with respect to the
X/Y plane.
-
Angle to y/z plane: The angle of the longitudinal axis of the calculated cylinder with respect to the
Y/Z plane.
-
Angle to z/x plane: The angle of the longitudinal axis of the calculated cylinder with respect to the
Z/X plane.
-
Radius: The radius of the calculated cylinder.
-
Number of points: The number of points in the point cloud that were used to calculate the cylin-
der.
-
Sigma: The standard deviation of the distances between the points that were used to calculate the
cylinder and the surface of the calculated cylinder.
-
Peak to Valley (PV): The distance between the two points that are furthest away inwards and out-
wards from the surface of the cylinder, relative to the computed cylinder. The two points are deter-
mined from the points that were used to calculate the cylinder.

A "General" toolbar: Using this toolbar, you can select the data source (see Chapter
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.
Chap. 3.14) and select an active measuring program for parameterizing and displaying the
measured values.
