Astronomical positioning and automatic tracking method and system for space target and electronic equipment

Abstract

The invention provides an astronomical positioning and automatic tracking method and system for a space target and electronic equipment. The method comprises the following steps: acquiring an astronomical image of a space target and preprocessing the astronomical image; inputting the preprocessed astronomical image into a trained space target astronomical positioning and automatic tracking model based on satellite laser ranging (SLR) to obtain real-time position information of the space target output by the space target astronomical positioning and automatic tracking model, wherein the space target astronomical positioning and tracking model is used for determining position information of the space target by extracting an image centroid and a predetermined negative film model, and generating position correction information of the space target in real time based on the position information so as to correct the position information of the space target; and realizing automatic tracking of the space target based on the corrected real-time position information of the space target, and generating position correction information of the space target by performing background threshold calculation, target detection and / or star map matching on the astronomical image.

Description

technical field [0001] The invention relates to the field of astronomical positioning, in particular to a method, system and electronic equipment for astronomical positioning and automatic tracking of a space target. Background technique [0002] Space objects include orbiting spacecraft and space debris, most of which are space debris. In recent years, human space activities have become more frequent, the space environment is deteriorating day by day, and space debris seriously threatens the safety of spacecraft. It is urgent to conduct in-depth research on how to identify and track space targets in real time and accurately. As the most accurate means of monitoring space debris, laser ranging has been used by various countries to monitor space debris and ensure space safety. Compared with spacecraft in orbit, the orbit prediction of space debris is poor, and it cannot be quickly and accurately identified and tracked. Therefore, image recognition and positioning of space t...
