| Abstract: | The photogrammetric processing of lunar rover' s stereo image is a most important method to obtain lunar surface information and navigate the rover.Image matching is key technology to realize the data processing automatically in close-range photogrammetry.This paper studied on the multi-core CPU parallel matching algorithm based on integral image.Matching results of lunar simulative stereo image could be obtained quickly.It was proved by experiments that this method could remarkably reduce matching time to achieve higher speed-up ratio and efficiency. |
