4.3.9.4 Configuring inspection models
Introduction to inspection models
Inspection models make it possible to combine several models of PatMax, blob,
histogram, Caliper, and external models. This is sometimes referred to as Inspection
II.
An inspection model always consists of an alignment model. The alignment model
can either be a PatMax, blob, or external model and works as the reference for the
inspection model. It is this model's position and rotation that is the pick/place
position and rotation for the item.
Inspection areas are defined relative to the alignment model and either blob,
PatMax, histogram, Caliper, or external analysis can be done within each of these
areas. Conditions such as number of found items and location relative to the
alignment model can be set.
For a found item to be classified as accepted, all inspection areas and the alignment
model must be classified as accepted. If one of the inspection areas does not fulfill
the given conditions the corresponding item is classified as rejected.

Tip
A more advanced accept or reject decision can be implemented with a user hook.
By adding a selection of upto 5 vision parameters for storage in the item targets,
a user hook can implement an advanced accept or reject decision based on the
selected parameters and other item target data (for example, position and
orientation). For example, the combination of 5 measured caliper distances can
be evaluated for the accept or reject decision instead of having a fixed allowed
maximum or minimum interval for each caliper distance.
