Abstract
In order to solve the problem of image matching, the points matching in the fields of digital photogrammetry and computer vision is researched very deeply. The accuracy of the feature points plays an important role in making right matching results. The paper introduces a method of 3-D Harris detector. An algorithm of Gaussian smoothing is applied for eliminating sudden gray change. Corners of all pixels are detected in a video using Harris. The results of experiments show that the 3-D Harris detector is accuracy and efficient.
