Abstract

The Multi-Hypothesis Tracking (MHT) method is one of the most promising approaches to realize automatic tracking of small and dim targets in complex space scene. However, the number of hypotheses generated by this algorithm has an exponentially increasing relationship with the number of trajectories, measurement data, and the number of image frames. In the paper, the automatic detection and tracking method of judging the confidence coefficient of the trajectory obtained by the MHT which is based on the characteristics of dim targets, has been realized in the IRST system. The performance of this method is greatly improved.

Summary

INTRODUCTION

Automatic tracking technology based on image is one of the important research inspects of Machine Vision Application, and key technology of automatic target detection. Infrared Search and Track (IRST) based on obtaining 2d infrared images, has the advantages of large field of view, small size, and working all day to be used Detecting and tracking space targets by receiving infrared radiation from targets and background. It is commonly used in space craft to realize automatic detection of target for Engineering Applications.
