Image stitching source code, VC ++, image stitching an important role in the process of making the panorama. Multiple images for projection after a specific pattern, Strike with the constraints of the law related to horizontal and vertical phase offset, and then find the best suture line, and image stitching, Finally, multi-resolution algorithm to map the entire splicing to remove differences in exposure and ghosting. The whole process to be implemented by VisualC ++, experimental results demonstrate the effectiveness of the algorithm.
