Pattern Recognition The M3 pattern recognition function teaches specific image patterns to the system for automatic detection during program playback. Program playback can be improved using a soft-fixture based part alignment routine, utilizing this pattern detection mechanism. Patterns can be measured or taught as datum patterns where the skew and zero positions are set automatically, or as standard pattern features where the part or machine coordinate pattern position and orientation are reported for the pattern feature. NOTE Pattern recognition is supported in CNC systems or in manual systems that also have the Digital Comparator option enabled. Pattern recognition is also supported in non-CNC Field of View systems discussed in Section12: Field of View Functions. Teaching a pattern Select the desired pattern to be used for detection in playback. Ideal candidate patterns should contain image characteristics that are unique relative to the rest of the field of view in which they are taught. In addition, target pattern regions should contain reasonable light to dark pixel contrast and be relatively free of image noise and distortion.
