| description | The invention discloses a ghosting removal method and system for a microsatellite sun sensor, and the method comprises the steps: S1, enabling light to form an image on an image sensor through a panoramic fisheye lens; s2, performing line-by-line and pixel-by-pixel processing on the formed image from top to bottom and from left to right based on cpld, and calculating weight data of solar facula; and S3, transmitting the weight data to the mcu to calculate a solar facula centroid position so as to obtain the solar facula centroid position. According to the method, the sun image and the ghosting are processed from the software level, and the influence caused by the ghosting is reduced. After the method is used, the influence of ghosting can be successfully filtered out by the too sensitive number, and the precision problem of a specific angle is solved in the subsequent calibration and use process.
