Abstract: The image fusion as well as high—precision measurement method is applied to astronomical image processing，In processing the final image the efective point spread function can be obtained，and the star’S position and brightness information can be got by the e—PSF fitting astrology．The mean precision of x directions was 0．036 pixels，the mean precision of Y directions was 0．044 pixels，and the mean Photometry precision was 0．015magnitude．The measurement results verify the effectiveness of the algorithm．

Key words: Image fusion；e-PSF；High precision measurement
