Search Processing Mechanism
Reference image patterns are registered as models and then search is performed for the parts of input

ue, inspection for defects and different parts being mixed in can be performed.
The search process is performed over several distinct stages.
1 Register a reference model.
Register the package
marking as a model

Model Status and Measurement Processing
• Measurement time and accuracy may be affected by the status of model in the following
ways. Please select measurement objects that are in good condition (clean) for Model Regis-
tration.
- In the case of large or complicated models, processing time is prolonged.
- With extremely small models or models without features, search processing is unstable.
2 Perform rough search of overall measurement region.
