Cylindrical panoramic image stitching method based on multi-cameras

摘要

Panoramic stitching technology is the focus of current panoramic technology, and cylindrical panoramas are commonly used because of their ease of capture and storage. Moreover it is a simple method for constructing panoramic video. This paper presents a cylindrical panoramic generation method based on multi-cameras. First, we use a backward-division model, which can rapidly solve the distortion of fish eye lens. Second, in order to maintain consistency of stitching, use the cylindrical projection. Third, we apply SIFT feature detection method to image mosaic process. To ensure the accuracy of matching, we use the RANSAC algorithm to purify the detected feature points. In addition, we use an image fusion method based on Lapalace pyramid. The original images captured by fisheye multi-cameras device are processed according to the procedure described in this paper, and then the cylindrical panoramic image is obtained.
