The invention discloses a method for enhancing and extracting high stars and other sliding fixed stars in the view field of a telescope. Aiming at the problems that high background stars and other sliding fixed stars are low in detection rate and not high in positioning precision in the celestial positioning process, the astronomy and an image processing technique are combined, the sliding tracks of the fixed stars are calculated by using astronomical information, and reliable enhancement and high-precision extraction of the high stars and other sliding fixed stars are realized by using a background equalization method, a quasi-randomized orbital determination method, a noise normalization method, a double-threshold orbital determination correlation method, a two-step centroid extraction method and other image processing techniques, so that technical support is provided for the celestial positioning. The method has the benefits that the false detection rate and the misdetection rate are extremely low; the influence from interference factors among fixed stars, of other celestial bodies and background noise and the like can be better overcome; weak high stars and other fixed stars are extracted; information about the number, the size, the position, the precision and the like of the fixed stars are synchronously obtained; besides, fewer parameters are set and the set parameters are simple, and real-time processing can be realized.
