AV-2550 Pattern Recognition System
The AV-2550 Pattern Recognition System (PRS) magnifies the workpiece and displays it on
the computer monitor. The AV-2550 can be used with either FMW or FMDOS.
The AV-2550 has a Cognex
®
Vision Processor in addition to all of the same hardware as the
AV-700 described above. This vision processor can recognize certain shapes, called
fiducials, on the part or substrate and can be taught to recognize them on other parts for
quick, accurate pattern placement. Specific light levels and fiducial-find handling can be
specified for each fiducial. .
Light Source
There are two light source options available on the AV-2550: the Light Ring (see
Figure 9 1), and the Dual Light Source, which is better suited for the edge detection
method of fiducial location. The computer on a system equipped with the Dual Light Source
option has a Moritex
Control card in place of the light ring card.
