Searching and Matching

Creates a description of the template image for which you want to search during the matching phase of pattern matching. This description data is appended to the input template image. During the matching phase, the template descriptor is extracted from the template image and used to search for the template in the inspection image.

Searches for a pattern, or template image, in an inspection image. Run the IMAQ Learn Pattern 5 VI before this VI to configure the template image for the matching phase.

Retrieves the information used to learn the template image.

Calculates the defect map between the template image and the match image. For each match found, a corresponding defect map is created in Defect Images Out.

Sets parameters that are used during the learning process. Run this VI before using the IMAQ Learn Geometric Pattern 2.

Creates a description of the template image for which you want to search during the matching phase.

Sets parameters that are used during the matching process. Run this VI before using the IMAQ Match Geometric Pattern 2 VI.

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

Sets parameters that are used during the color learning stage. Run this VI before using the IMAQ Learn Color Pattern VI.

Creates a description of the color template image that you are going to look for during the color pattern matching stage.

Sets parameters that are used during the color matching process. Run this VI before using the IMAQ Match Color Pattern VI.

Searches for a color pattern, or color template image, in the input Image.

Reads an image file, including any extra vision information saved with the image. This includes overlay information, pattern matching template information, calibration information, and custom data, as written by the IMAQ Write Image And Vision Info File 2 instance of the IMAQ Write File 2 VI.

Writes an image, along with extra vision information associated with the image, to a PNG file. This extra vision information includes overlay information, pattern matching template information, calibration information, and custom data.

Searches for rectangles, lines, ellipses, or circles in an image.

Finds objects in an image whose shape matches the shape of the object specified by a template.

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

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