Abstract
PURPOSE:To detect the position of a subpixel precision by performing matching between a correlation value pattern of the subpixel precision and a correlation value pattern in the vicinity of the position where the correlation value is maximum at the time of matching. CONSTITUTION:When the position where the correlation value is maximum is obtained with the precision of 1/4 picture element in case of template matching of 7X5 picture elements, the inside and the peripheral part of a template 2 of 7X5 picture elements are interpolated with the precision of 1/4 picture element to obtain an interpolated image S. Matching between the template 2 and the interpolated image S is performed with the range of + or -6 picture elements from respective centers in X and Y directions as candidate points on the interpolated image S to obtain a correlation value two-dimensional image pattern C13 of 13X13 picture elements. In the figure, the oblique line part indicates the candidate point area on the image S, and grid points surrounded with circles indicate sampling picture elements at the time of matching at the center candidate point.
