Owning Palette: Searching and Matching
Requires: NI Vision Development Module

Use the Geometric Matching (Feature Based) VIs to locate regions in a grayscale image that match a template of a reference pattern.

Palette Object Description
IMAQ Setup Learn Geometric Pattern

Sets parameters that are used during the learning process of feature-based geometric pattern matching. Run this VI before using the IMAQ Learn Geometric Pattern.

IMAQ Learn Geometric Pattern

Creates a description of the template image for which you want to search during the matching phase of feature-based geometric pattern matching.

IMAQ Match Geometric Pattern

Searches for a pattern, or template image, in the inspection image.

IMAQ Setup Match Geometric Pattern

Sets parameters that are used during the matching process of feature-based geometric pattern matching. Run this VI before using the IMAQ Match Geometric Pattern VI.

IMAQ Read Multiple Geometric Template

Creates a new multiple geometric template from the file specified by File Path.

IMAQ Learn Multiple Geometric Patterns

Combines the descriptions of the patterns you want to search for during the matching phase into a multiple geometric template. Use the multiple geometric template to search for these template images in the target image.

IMAQ Match Multiple Geometric Patterns

Matches the templates specified in the Multiple Template control to the target image.

IMAQ Dispose Multiple Geometric Template

Destroys a multiple geometric template and frees the space it occupied in memory.

IMAQ Write Multiple Geometric Template

Writes a multiple geometric template to the file specified by File Path. This VI saves the exact state of the multiple geometric template.



Subpalette Description
Geometric Matching Advanced (Feature Based)

Use the Geometric Matching Advanced (Feature Based) VIs to optimize and fine-tune advanced parameters used during the learning and matching phases of feature based geometric pattern matching. These functions are intended for advanced users. Improper use may cause unexpected results.
