Based on the theory of the panoramic images, the panorama mosaic technology is studied and implemented. In this paper, we use the Harris algorithm with adaptive threshold to extract corners from image effectively, and give the corner multidimensional vector as feature descriptor, then make the corner point matching. After matching, we use method of RANSAC to remove pseudo-point. By least-squares fitting parameter matrix, we acquired the images' coordinate transform from one to another. At last, we obtain good visual effect of cylinder panorama. Experimental results show that the algorithm can quickly get the calibration for multi-purpose system, effectively generate 360-degree panoramic image, algorithm is adaptability and robust.
