)

Parameters

*image	Image data structure address
*figure	Figure data structure address
subPixcel	Sub-pixel 0: OFF 1: ON
standardX	Reference coordinate X
standardY	Reference coordinate Y
thresRough	Rough search candidate level (0 to 100)
thersDetail	Detail search candidate level (0 to 100)
*model	Model data
maxOutputNum	Maximum number of output point
*searchNum	Search points (measurement result)
positionX	Search coordinate X (measurement result)
positionY	Search coordinate Y (measurement result)
*angle	Search angle (measurement result)
*correlation	Correlation (measurement result)

Return Value

NORMAL(0): Successful completion

ERROR(-1): Unsuccessful completion

Description

To perform a search, perform the "search image creation for Hough conversion search" and then the "Hough conversion search" to calculate the candidate points.

Next, perform the "normalization CR search" for each candidate point, and output the position having the highest correlation value as the search position.

The search range is specified by a FIGURE structure, which must represent a rectangle figure.

Output all of the multiple coordinate values that exceed the candidate level.
