Title: A Fast All-sky Autonomous Star Pattern Identification Algorithm
Abstract: Triangle identification algorithm for star images has been widely used in attitude detection systems that take star sensor as navigation parts at present. An improved star identification algorithm based on the traditional triangle method is proposed in this paper to overcome the low character dimensions and high percentage of redundant matches in star identification.A real-time star image simulation method based on Stellarium software is proposed for the emulational test of star pattern recognition. The computation model for star image simulation is established. The simulation test results show that star image simulation for star sensor can be achieved under various operating conditions by using Stellarium software. The elements of simulation are completed and corrected. In the process of test star pattern recognition algorithm can meet the requirements of star sensor and high precision real-time simulation test. The foundation for equipment debugging,performance evaluation and ground test are laid. There is great significance to fully test software and hardware performance of star sensor, and the star sensor precision calibration is.
