An Automatic Space Target Measurement System Based on Active Search Strategy

Abstract

The invention relates to an automatic measurement system for space targets based on an active search strategy, which belongs to the technical field of automatic measurement of space targets. The system includes a system monitoring platform, an optical image acquisition device, and a target identification and tracking platform. device, tracking frame, angle measuring unit, electronic control unit, target recognition and tracking platform includes image acquisition card, image recognition and tracking unit, system monitoring platform includes automatic guide file generation unit, guide data display and control unit, active search control unit, Data processing and recording unit. The invention can automatically generate plan files, automatically load guidance data, automatically guide according to time information, and automatically identify space targets after guidance is in place; when there is a large error in the guidance data, the preset active search strategy is used to search for targets, further improving Improve the measurement efficiency of space targets and improve the automation level of the optical measurement system.

Description

technical field [0001] The invention relates to the technical field of automatic measurement of space targets, in particular to an automatic measurement system of space targets based on an active search strategy. Background technique [0002] Since the advent of the first optical telescope, optical telescopes have provided important assistance for the development of astronomy and military affairs. With the continuous advancement of science and technology, optical telescopes have also been updated rapidly, and their apertures have gradually increased. Especially since the 1980s, the application of CCD cameras and computer control technology has changed the way of measuring space objects. Space target measurement has changed from visual observation and hand-drawn recording by observers to a servo system guiding equipment to maneuver, a CCD camera to collect and record, an encoder system to read azimuth information, and a master computer to comprehensively process and record. ...

AI Technical Summary

Problems solved by technology

However, since the space target to be measured has no obvious difference in geometric characteristics and brightness from other stars, the identification of the target requires the observer to monitor the whole process and manually select the target. This method has high requirements for the operator, and the accuracy and efficiency are not guaranteed

At the same time, the existing target guidance method only guides according to the forecast guidance file. When the target guidance data has a large deviation, there is no effective means to search for the target outside the field of view. Human workload leads to measurement failure

In terms of the generation of guidance files, the generation of observation plans still adopts the method of manual planning, which consumes a lot of manpower
