Key Points for Test Measurement and Adjustment (Shape Search+)

The following content is displayed in the "Detail result" area as text.

Displayed items	Description
Judge	Judgement result
Count	Count
Correlation value	Correlation value
Measure X	X coordinate of the position where the model is detected
Measure Y	Y coordinate of the position where the model is detected
Angle θ	Angle of the position where the model is detected

Select the adjustment method referring to the following points.

Parameter to be adjusted	Remedy
Model parameter	Register the model from the following two perspectives. Register the model figure frame enclosing the boundaries of the target. In order to detect based on the edge information, improvement is made by including boundary information in the registration. When a model is registered near the boundary of the image or measurement region, some targets may be impossible to detect. Register the model leaving space from the boundary of the image or measurement region.
Measurement parameter	Specify a larger value for "Candidate LV". Specify a smaller value for the "Search skipping Level" in the detailed settings. These two settings have a trade-off with speed. Make the setting taking the affect on speed into consideration.

When a model is registered near the boundary of the image or measurement region, some targets may be impossible to detect.
Register the model leaving space from the boundary of the image or measurement region.

Measurement parameter

Specify a larger value for "Candidate LV".
Specify a smaller value for the "Search skipping Level" in the detailed settings.

These two settings have a trade-off with speed.
Make the setting taking the affect on speed into consideration.

Parameter to be adjusted	Remedy
Model parameter	Specify a narrower "Angle range".
Region setting	Specify a smaller value for "Measurement region".
Measurement parameter	Set the "Sub-pixel level" in the detailed settings to "Fast". This setting has a trade-off with precision. Change this setting according to what the application is used for.
Measurement parameter	Specify a larger value for "Candidate LV". Specify a smaller value for the "Search skipping Level" in the detailed settings. These two settings have a trade-off with speed. Make the setting taking the affect on speed into consideration.
