Abstract
The key in star map recognition is CCD star sensor. Taking account of this importance from the match mode of string, first passing star map through high-pass filter, then a nautical star database established with 0 and 1 method, star map recognition is carried out by KMP algorithm. Simulation results show that the identification time of the algorithm for each area is only 0.2486 ms. The faults are overcame that the discrimination is seriously lowered among many bright stars or within a visual domain of very small diagonal distance. The algorithm has a good robustness.
