All-sky autonomous star map identification algorithm based on Delaunay triangulation cutting algorithm

  • In the field of geophysical model building,Delaunay triangulation cutting algorithm has been widely used because of having a very important characteristic which is the result of this triangulation cutting method being unique in a specifically set of points.This character was adopted, the algorithm to identify star map for the first time was used.Making use of the invariability of cutting in all-sky star atlas and adopting the boundary recursive method for constrained triangulation of surfaces,the guidance stars database which was arranged under specific rules and whose size was comparatively small was constructed;the recognition algorithm utilized the result generated by Delaunay cutting star map in a specified field of view to match and identify quickly.The simulation results show that compared with the current star map identification algorithms,this algorithm has a high rate of discrimination,the advantages of real-time properties and robust;and it only needs a small content database and searches more rapidly.
