Locate Tool Parameters

 

The Relaxed, Normal, and Precise settings of this parameter are all designed to set the Accept Threshold and Conformity Tolerance automatically. You can still adjust the Accept Threshold and Conformity Tolerance settings, but re-training the tool will cause these parameters to revert to the recommended values for Relaxed, Normal, or Precise fit quality. This behavior may not be appropriate for all applications, however, and you may wish to adjust the Accept Threshold and Conformity Tolerance manually to achieve the best location performance. In such a case, you should select Manual from the Fit Quality dropdown menu. When Manual is selected, you can set the desired Accept Threshold and Conformity Tolerance and those values will not change.

 

 

 

 

 

 

Hint: The Locate Tool is configured to handle 360 degrees of rotation by default. However, reducing the Allowed Rotation (± Degrees) will speed up the tool's performance considerably.

Locate Tool (Locate Shape) Advanced Parameters

 

Effort Level provides a mechanism for adjusting the recognition effort for the tool. There are five options available: Lowest, Low, Normal, High, and Exhaustive. This setting has a large impact on the robustness of the tool at the cost of performance. Normal is adequate for most operations.

 

 

 

Positioning Accuracy provides a mechanism for adjusting the speed/accuracy tradeoff of the positioning process though a scale that ranges from Fast to Accurate. Options are Fast, Coarse, Normal, Fine, and Accurate. Normal is adequate for most operations.

 

 

 

Enable Scale Search enables scale intolerance searching to locate the object if it is larger or smaller than a trained model. Note that enabling Scale Search increases search time similar to enabling rotation search.

 

Minimum Scale sets smallest search size of model. A value of 0.5 corresponds to 50%.

 

Maximum Scale sets largest search size of model. A value of 2 corresponds to 200%.

 

Conformity Tolerance allows you to set custom conformity tolerance. This is the width of the band +/- in pixels within which the contour is allowed to vary and still be found. If part shape varies slightly between parts, increasing conformity tolerance allows it to be located more easily.

 

Example: The image below shows a large conformity tolerance. The cross edges can vary anywhere within the yellow boundary and still be considered part of the model.

 

 

 

Min % of Model Match is the value for which a possible match will be further analyzed as a final match candidate. This should always be set lower than the Accept Threshold.

 

Model Name (Read-Only) is the name that AutoVISION automatically assigns to the locate model.

 

 

Locate Tool (Locate Blob) Advanced Parameters

 

 

See Count Tool Parameters for details about blob functionality. Locate Blob parameters are the same as the normal settings for the Count Tool, which also uses blob algorithms.
