A novel method for subdivided locating of star image in star identification

A novel method is put forward in subdividing locating of star image in this paper, which is based on super resolution image reconstruction that can generate high resolution image with more information contained by using one or more low resolution images. There are methods of super resolution reconstruction and camera calibration introduced in order to simulations results, and researching the angular distances obtained systematically. By comparing the angular distances with real angular distances in star database, the results show that angular distance achieved from super resolution reconstruction star map is closer to real value, with the precision 21.70% improved than that from original star map.
