4.3 Object overhangs, object bulges
This chapter describes the function of overhang suppression and the detection of bulges. For the
settings of these functions in WebConfig, see Chapter 8.2.2.
The evaluation of measurement objects for projections and bulges is always carried out in 2 steps.
4.3.1 Operating principle
In stage 1, the system determines overhangs in length, width and height from the raw object data and
suppresses them according to the threshold value entered. The suppression serves to ensure that
overhangs on the object that do not interfere with further handling do not influence the object
measurement.
In stage 2, the system determines the cuboid corner points of the object from the overhang-reduced
object data and calculates the bulges between the corner points. The determination of the bulges is
called deformation detection.
Deformation detection can only be selected in conjunction with object overhang detection.
Example
Figure 5
shows an object with overhang and bulge. The overhang has the width ∆A. The bulge has a
maximum length of Xnet-Xmin.
