If the
Identity
option is enabled, the transformation matrix of the identical 2D
image is used. In this case it is not necessary to apply the settings (the
Teach

Overview
The abbreviation
3E
stands for an alignment over the 3 search edges (3 edges) that are
used to scan the inspection object.
First, a straight line is placed through the midpoints of edges 1 and 2. Then, starting
from the midpoint of edge 3, a straight line orthogonal to the first straight line is
determined.
In the following figure, the edges of the first straight line are located on the bar that is
perpendicular in the image (marked 1 in the image). The edge of the orthogonal straight
line (marked 2 in the picture) is located at the bottom edge of the inspection object.
The midpoints of the edges are represented in the image by a red cross. The deter‐
mined straight lines by orange lines.
Using this combination, it is possible to determine an origin and an angle for a coordi‐
nate system that describes the position and orientation of the inspection object in the
camera image. This coordinate system is shown in turquoise in the image. The origin
and the angle of the axes to the image edges give the position and orientation of the
inspection object.
