Heliostat correction system based on celestial body images and its method
A heliostat correction system includes an image acquisition module for acquiring the image of a celestial body in a field of view and sending the image to a data analysis module which analyzes the deviation value between the celestial body image and the image center in an image coordinate system and transmits the deviation value to a correction calculation module which decomposes the deviation to a corresponding rotation axis according to the rotation mode of a heliostat to obtain the deviation angle of each rotation axis; a data storage module is used to store the correction result of the heliostat and the single correction period control command list of the heliostat; a communication module reads the single correction period control command list from the data storage module, sends the list to the heliostat, and simultaneously controls the image acquisition module to shoot according to the rotation period of the heliostat.
