Abstract:

This article proposed one kind of fast celestial chart recognition method. This method extracts the onedimensional feature P-which marks the triangle uniquely. Computation of P- value from the observed star map speeds up the get of the correspondence navigational triangle. This method reduces the computation process. Because of the star position error, more triangles within some scope should be selected. Then verification process is introduced to confirm the identification results.

Key words: astronomical , instrument, star , sensor,  , fast , star , identification,  , P , vector,  , star , triangle,  , principle , component , analysis
