Star map simulation method and system, computer equipment and computer readable storage medium

The invention relates to the technical field of celestial navigation, and particularly discloses a star map simulation method and system, computer equipment and a computer readable storage medium, and the method comprises the following steps: carrying out right ascension and declination partitioning on a celestial sphere to obtain a plurality of first partitions of the celestial sphere; according to the optical axis direction and the rectangular view field of the star sensor, determining second subareas from all the first subareas, and constructing a minimum subarea corresponding to each second subarea; and determining the fixed stars in the imaging range of the star sensor in the minimization subarea as observation stars of the celestial sphere, and carrying out star map simulation according to all the observation stars. The method can reduce the discrimination range during star map simulation, reduces the discrimination frequency, and improves the generation efficiency. 本发明涉及天文导航技术领域，具体公开一种星图模拟方法、系统、计算机设备和计
