Pattern Recognition (XDLM 237)
11.Define the search area:

Position of the search area: Place the cursor in the rectangle, keep the left mouse button
pressed and move the rectangle.

Size of the search area: Place the cursor on one of the eight black points, keep the left
mouse button pressed and change the size of the rectangle.
If you automatically measure specimens that are in a row, then the search area must always be
to the right (or left) of the first specimen. This produces an automatic feed. If the search area
contains several identical specimens, then experiment with the
Algorithms > Center weight
parameter or decrease the search area.
12.To test the function of the pattern recognition, carry out the following steps:
a Move the XY-stage so that the first SMD component is in the search area.
b Click
Find in the pattern recognition window.
The XY-stage moves to the first/next measuring position.
c Repeat step b.
If the XY-stage does not correctly move to the first measuring position, then check the following:

Are the SMD components arranged equally spaced on a line?

Is the ratio of component size to distance selected so that only one component is completely
in the search area? If there are two components in the search area, for example, then exper-
iment with the parameter
Algorithms > Center weight or decrease the search area.
