SearchBreadth Property

Applies To
Vision Objects: GeometricPlus

Description
Specifies the level of detection candidate count to pass from coarse search to detailed search, or from coarse search to final search.

Usage

    VGet  Sequence.Object.SearchBreadth, var
    VSet  Sequence.Object.SearchBreadth, value

Sequence

Name of a sequence or string variable containing a sequence name.

Object

Name of an object or string variable containing an object name. The object must exist in the specified sequence.

var

Integer variable that will contain the value of the property.

value

Integer value or expression for the new value of the property.

Values

• 1 - Low
  • Vision constant: VISION_SEARCHBREADTH_LOW
• 2 - Medium
  • Vision constant: VISION_SEARCHBREADTH_MEDIUM
• 3 - High
  • Vision constant: VISION_SEARCHBREADTH_HIGH

Default:2 - Medium

Remarks
The SearchBreadth property adjusts the level of detection candidate count passed from coarse search to detailed search, or from coarse search to final search. For GeometricPlus objects, after performing coarse search, the search result coordinates are passed to detailed search or final search to calculate more precise coordinates. Not all coarse search results become the final output coordinates, only the results that are deemed more accurate are output in accordance with the value of the NumberToFind property. When there are many coarse search results, processing time tends to increase. For images with little noise or edge variation, setting the SearchBreadth property to 1 - Low and reducing the coarse search results can sometimes reduce processing time. However, if the coarse search results are fewer than necessary, there is a possibility that the correct detection position cannot be output. Therefore, when increasing the value, set it to 3 - High. Adjust by balancing processing time and detection results.
