Abstract:

Proposed a triangle method to describe Harris feature points, firstly, the algorithm uses Harris operator to detect the corner points of the two images, then sorts the corner points in accordance with the size of the weights, and uses the triangle method to describe the feature of the feature points in order to identify the feature points’ corresponding relationship between the two images, and has also obtained the image registration parameters. Experimental results show that the algorithm with high accuracy, speed, and has a strong robustness.

Key words: image registration;Harris corner detection;feature extraction, console point matching
