Model Registration (Fine Matching)

Register a fine image as the model.By matching this model with input images, unmatched parts will be detected as defects during inspection.

Note

Ranges that can be registered as models

The two pixels on the edge of the screen are not registered as a model.
The registering range will be lower if the images of measurement object are set with Filtering.When you set the image reading range using a camera with the partial scanning function, the range is also limited.Filtering

In the "Item tab" area, tap [Model].
When setting a new model, you do not have to tap [Model].
Use the drawing tools to specify the model registration range.
In the figure setting area, tap [OK].
The model is registered.

The range can be changed as needed to address unstable measurement results.Normally, the factory default value will be used.

After changing a setting, check whether measurement can be done properly by performing an actual measurement.

In the "Model parameter" area, specify a value for each item.

Setting item	Set value [Factory default]	Description
Boundary inspection	[Checked]	Defects around boundaries with color changes can also be detected.The edges similar to those in the model image are not regarded as defects. Check this option when inspecting defects around boundaries, such as chips and burrs. Defects along a direction different from the model image profile are detected in the range of pixels of profile ± boundary level.
Boundary inspection	Unchecked	Boundary areas are excluded from the inspection.This can prevent matching mistakes due to positional deviation of measurement objects, but defects around boundaries cannot be detected. "Boundary level" can be used to specify how many pixels around boundaries should be excluded from the inspection.
Boundary level	0 to 8 [3]	Select the degree of assimilation of variations around boundaries. Depending on the "Boundary inspection" value, the meaning is different.
