6.1.9 “Edge” Measuring Program
Use the “Edge” program to measure a straight edge in a point cloud.
Note: The “Edge” 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 ). Move the measuring program such
that it comes before the “Edge” 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 edge measurement (see below, section “E” and Chap. 3.16.4 and 3.16.5 ).
Make 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 edge and such that ex-
actly one edge is in the ROI.
-
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 “Edge” program in order to ob-
tain valid measurement results.
Note: Unlike other measuring programs, only one ROI can be used in the “Edge” measuring program.
