Embedded guiding star processing system

Abstract

The invention discloses an embedded guiding star processing system, relates to a space target guiding star-oriented embedded processing system, and aims at solving the problem that the existing imageacquisition and processing systems are difficult to answer huge real-time data size and difficult to guide stars so that the main visual fields cannot observe space targets for a long time. The systemcomprises an image acquisition module and a guiding star calculation module, wherein the guiding star calculation module adopts a guiding star processing system constructed by FPGA and DSP heterogeneous processors; the image acquisition module acquires video signals of an sCMOS camera in real time and stores the video signals to a DDR3 SDRAM; and the image data in the DDR3 SDRAM is transmitted tothe guiding star calculation module. According to the system, strong image processing and calculation analysis abilities are provided, space targets can be recognized and accurate mass center positions of the space targets can be obtained, the calculated error vectors are converted into practical miss distances of telescopes, and the practical miss distances are fed back to pointing control systems of the astronomical telescopes. The embedded guiding star processing system is capable of improving the stability and accuracy of the guiding stars and achieving the long-time observation for the targets.

Description

technical field [0001] The invention relates to an embedded processing system for space target guide stars. Background technique [0002] For the precise observation of space targets, if the main field of view of the telescope is relatively small, and the space target prediction error is large, the target cannot enter and stabilize in the main field of view. At this time, a large field of view guide star telescope is needed to image a large range of airspace, search for targets, and guide the targets into the main field of view. [0003] Therefore, the guide mirror is a telescope attached to the main telescope barrel to monitor space targets. It plays the role of the main telescope to accurately track the space target. Once the space target in the field of view deviates from the correct position, it can be corrected by the driving device of the telescope. [0004] According to the target forecast file, the program tracking method is adopted to guide the telescope to track ...
