摘要	A fast radial featured star pattern recognition algorithm with compensate code was proposed to solve star model that constructed by traditional radial featured star pattern recognition algorithm could be vulnerable to position noise, lead to low recognition rate. This algorithm adopt byte vector form to construct radial feature vector, meanwhile neighbor angle distance and compensate information were added to feature vector to reduce guide star catalogue capacity and to effectively increase stability and recognition rate of star pattern recognition algorithm. In addition a minimum similar difference matching method was formulated according to the characteristics of byte vector thus completing initial matching between the observation star and the guide star. Fathermore, the characteristic of position information coherency of stars in the same field of view was applied for accomplish exclusive recognition. The result of the experiment shows that recognition rate is 97.8% under position noise of 0.5 pixel, and under magnitude noise of 0.8 Mv is 96.4%. For recognition of real star images, the recognition rate of this algorithm achieves 94.2%. Compared with the triangle algorithm and the traditional radius recognition algorithm, the recognition rate and time of this algorithm are improved in various degrees. 2017, Science Press.
