For the purpose of improving the recognition rate and the anti-noise ability, a new star pattern recognition algorithm is proposed, which is based on optimal singular value decomposition matching. The algorithm can effectively solve the recognition failure caused by redundant matching results, which the triangle recognition algorithm and the pyramid algorithm can not. Compared with traditional star pattern recognition algorithms, the recognition rate and the anti-noise ability of the new algorithm proposed in this paper are improved. With the star position noise added (Gauss noise, mean=0, σ=3pixel), the recognition rate is 98.91%, and the average recognition time assumption is 20.21ms.
