Abstract

Embodiments of the invention provide a digital star map simulation method and device. The method includes acquiring simulation parameters; searching a target observation star zone meeting the simulation parameters from a database based on the simulation parameters; acquiring a target observation fixed star meeting the simulation parameters from the target observation star zone based on the simulation parameters; calculating the planar coordinates and the grey level of the target observation fixed star; and outputting a star map simulation image corresponding to the target observation star zone according to the grey level and the planar coordinates of the target observation fixed star. Through simulation of a needed star map, a digital star map is generated, thus providing image data supports for star sensor technique research, and pushing research development of the star sensor technique.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a digital star map simulation method and device. Background technique [0002] Accurate measurement of attitude is an important guarantee for the smooth flight of a spacecraft, and the star sensor is currently the most accurate attitude measurement instrument. To study star sensor technology and improve its performance is of great significance to improve the design quality and operation of star sensor system. However, the study of star sensor technology requires a large number of star maps to verify the feasibility and performance of key technologies. However, not all required star maps can be obtained through actual shooting, which limits the research and development of star sensor technology. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a digital star map simula...
