METHOD FOR CALCULATING HAUSDORFF DISTANCE BASED ON GRADIENT ORIENTATION INFORMATION

摘要

According to an embodiment of the present invention, a Hausdorff distance calculation method based on gradient direction information includes: (a) extracting Harris corners from a visible image and an infrared image; (b) classifying the Harris corners into a plurality of corner subsets according to a gradient direction of each corner; And (c) calculating a weighted Hausdorff distance based on the Hausdorff distance of the corner subsets, thereby improving the registration accuracy of the multi-sensor images since the Hausdorff distance can be accurately calculated .
