FindTransformPatternOptions

NI Vision for LabWindows/CVI Function

FindTransformPatternOptions

An array of angle ranges, in degrees, where each range specifies how much you expect the pattern to be rotated in the image. To decrease the search time, limit the degrees of rotation in which you expect to find the template image. Set this element to NULL to allow all angles.

Description

matchMode MatchingMode Specifies the technique to use when looking for the template pattern in the image.
minMatchScore int The minimum score a match can have for the function to consider the match valid.
subpixelAccuracy int Set this element to TRUE to return areas in the image that match the pattern with subpixel accuracy.
angleRanges RotationAngleRange* An array of angle ranges, in degrees, where each range specifies how much you expect the pattern to be rotated in the image. To decrease the search time, limit the degrees of rotation in which you expect to find the template image. Set this element to NULL to allow all angles.
numRanges int Number of angle ranges in the angleRanges array.
showSearchArea int If TRUE, the function overlays the search area on the image. If you do not want this information overlaid onto the image, set this element to FALSE.
showFeatureFound int If TRUE, the function overlays the locations of the center of the pattern and the bounding box of the pattern on the image. If you do not want this information overlaid onto the image, set this element to FALSE.
showResult int If TRUE, the function overlays the position and orientation of the coordinate system on the result image. If you do not want this information overlaid onto the image, set this element to FALSE.
