In order to solve the problem of insufficient recognition, in the current target identification algorithm under the prospect of sheltering and complex background interference, this paper put forward the feature point robust match algorithm based on improved brief, goals. First of all, to identify interference image analysis, Brief, algorithm and improvement ideas were put forward. And then, to improve the Brief feature point detection, fast robust Brief feature points detection operator is put forward. Finally, by expanding the scope of the filtering processing target integral image, improve the Brief description operator. Algorithm is realized and test by using C language. The test results show that compared with the traditional target recognition algorithm, the target block, the interference of background is extremely complex, the algorithm has strong ability of recognition in this paper.
