Geometric
A geometric sub inspection model is configured in the same way as a PatMax
model. See
the relative positions of the found items and the corresponding alignment hit must
be trained.
Required hits defines the number of hits with the sub inspection model within the
inspection area that are required for the result to be considered as accepted.
Deviation limits defines the allowed deviations from the trained positions.
After a search and the items are found within the inspection area their positions
must be trained. The relative positions are listed as xDiff, yDiff, and AngleDiff.
Click Train to save the positions of the found items relative to the alignment hit.
Geometric subinspection parameters in item targets
The parameter Number of hits can be selected for the target storage.
Blob
A blob sub inspection model is configured in the same way as a blob model. See
Configuring blob models on page
be configured.
Required hits defines the number of hits with the sub inspection model within the
inspection area that are required for the result to be considered as accepted.
Blob subinspection parameters in item targets
The parameter Number of hits can be selected for the target storage.
Histogram
The histogram tool measures the color or the gray level within any given area.
While using a monochrome camera the histogram tool measures the gray level
within a given area. Similarly, if a color camera is used each of the three color
channels (Red, Green, and Blue) is measured separately. The histogram tool is
useful when the objects to be identified and classified have similar shapes but
different colors.
