Abstract
The present invention is applicable to the fields of panoramic images and videos, and provides a panoramic image and video splicing method, and a panoramic camera. In the present invention, fisheye photos captured by two adjacent cameras are mapped to corresponding seam areas of a sphere model, so as to form two strip graphs having overlapping areas; performing block template matching on the two strip graphs to obtain an initial template matching result; performing matching filtering on the initial template matching result by using an area expansion-based matching filtering algorithm, so as to obtain a final matching result; and updating a mapping relationship between the fisheye photos and the corresponding seam areas of the sphere model, and performing panoramic splicing according to the updated mapping relationship to obtain a seamless panoramic image.
