Implementation of Real-time Detection Algorithm for Space Debris Based on Multi-core DSP

Abstract

Abstract The purpose of this paper is to implement a real-time detection algorithm for CCD star image on multi-core DSP platform. It can effectively identify weak stellar targets and space debris. It mainly includes two parts: the space debris detection method and DSPs’ project. there are several steps in this algorithm: background suppression, smear removing, stellar targets detection, space debris detection, track establishment. As for implementation, This project includes three parts: communication port design, pipeline design and memory partition. The final results show that the platform given in this paper can successfully detect weak stellar targets and space debris in real time, and establish tracks with high-accuracy of the space debris in complex environment. The maximum time of processing a 2048*2048 (in gray 16-bit sets) image is approximately 600ms.
