| Abstract: | A method for space target extraction in star background image based on star image simulation is put forward. The star image simulation model of optical measuring equipment based on the foundation was established. Optical axis direction and coordinate transformation between stars and focal plane were calculated. Masks were generated by star image simulation,and background stars were removed for real star images. Experimental results show that the method can remove the background star and extract space target effectively. |
