description The invention discloses a star map registration method and system. The method comprises the steps of obtaining a reference image and a to-be-registered image and performing block division; selecting a template image from each block of the to-be-registered image, and performing template matching on the template image and the reference image to obtain a matching coordinate point of integer pixel precision; constructing a curved surface model according to the matching coordinate points of the integer pixel precision, and calculating the curved surface model to obtain a sub-pixel matching result; calculating a homography matrix of the image to be registered according to a sub-pixel matching result; and performing target detection on the to-be-registered image, and registering a target detection result by using the homography matrix. The system comprises a block division module, a template matching module, a curved surface construction module, a calculation module and a registration module. According to the invent
