6.1.7 "Circular Pad" Measuring Program

Use the "Circular Pad" program to measure a circular pad in a point cloud.
Note: The "Circular Pad" program also requires a reference plane in addition to the point cloud as input
data. This reference plane can be calculated using the "Plane fit" measuring program (see Chap. 6.1.3).
Proceed as follows:
-
First, if you have not already, insert the "Plane fit" measuring program and configure the measuring
program in order to obtain a reference plane (see Chap. 6.1.3). Please note that you should use
the points of the pad for computing the reference plane. Move the measuring program such that it
comes before the "Circular Pad" program in the list of active measuring programs (see Chap.
3.14).
-
Select the input point cloud and the reference plane for the program (see below, section "1" and
Chap. 3.16.3).
-
Define a ROI for the pad measurement (see below, section "E" and Chap.
sure that the ROI is as small as possible. You should choose the ROI such that the center point of
the ROI is as close as possible to the expected center point of the circle.
-
If required, activate the optimized fit and enter a suitable threshold for the optimized fit (see below,
section "2").
-
If necessary, change the edge threshold (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).
Note: Unlike other measuring programs, you have to define a ROI in the "Circular Pad" program in order
to obtain valid measurement results.
Note: Unlike other measuring programs, only one ROI can be used in the "Circular Pad" measuring pro-
gram.
