Research on Star Identification Algorithm

In view of the traditional star identification method requires large storage space, real-time recognition algorithm is bad, and the problem of common recognition rate is not high, this paper adopts spherical triangle geometry application, basic angular distance processing methods, such as spherical triangle model was established, the star sensor imaging model, using the classic triangle algorithm, grid algorithm and combines measurement function and grid algorithm, considering the amount of calculation step by step, such factors as the position of the stars, noise interference, analyzes its recognition rate and recognition time, compared to select the optimal algorithm, implements the intelligent matching on the map. Finally, this paper selects 8 star map related data for verification, and the experimental results show that the improved raster algorithm can quickly and accurately match and identify.
