IMAQ Learn Geometric Pattern 2 VI

Origin Offset specifies the number of pixels the VI shifts the origin of the template from the center of the template image. The origin offset is used by the IMAQ Match Geometric Pattern 2 VI to set the Position element of the resulting Matches cluster for each template match within a target image. The default value is (0, 0), which sets the center of the template image as the origin of the template.

Template Image is a reference to the template image for which you want to search in the inspection image during the matching phase.

Learn Geometric Pattern 2 Setup Data is a string that contains information obtained from the IMAQ Setup Learn Geometric Pattern 2 VI or the IMAQ Advanced Setup Learn Geometric Pattern 2 VI. If this input is not connected, the VI uses default parameters during the learning phase.

Learn Mask is an optional, 8-bit image of the same size as the template that specifies where to search for edges in the template. Use the following pixel values when constructing the mask:

• 0—Maintains the default behavior. The corresponding pixel in the template image is considered an edge only if it meets the conditions specified by the Curve Parameters in the IMAQ Setup Learn Geometric Pattern 2 VI or the IMAQ Advanced Setup Learn Geometric Pattern 2 VI.
• 1—The corresponding pixel in the template image is never considered an edge.
• 2—The corresponding pixel in the template image is always considered an edge.
• 4—The corresponding pixel in the template image is not used when computing the Correlation Score.

error in (no error) describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

	status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

Angle Offset specifies the angle by which each match is rotated round the origin of the template. The angle offset is used by the IMAQ Match Geometric Pattern 2 VI to set the Angle element of the resulting Matches cluster for each template match within a target image. The default value is 0 which does not change the angle of the matches.

Template Image Out is a reference to the template. This template image contains the data that defines the template pattern for the matching phase.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
