摘　　要：设计了一种用于空间目标探测的红外精跟踪系统。该系统基于ADSP-TS201 DSP,系统的软件设计采用了VDK内核。针对获得的空间目标红外图像特性,综合采用了自适应背景去除、动态阈值、卡尔曼滤波的目标检测和跟踪算法。实验结果证明,本设计可满足系统对空间目标实时跟踪要求。A Space-Target IR Tracking System has been designed.The hardware and software structure are introduced.The system is designed based on ADI-TS201 DSP and the software is designed based on VDK core.According to the characteristics of Space-Target IR image,background image is subtracted from the source IR image at first,then adaptive threshold is adopted,Kalman filter is used to estimate the track of the target.It turns out that the design can meet the requirement to track the space targets in real time.
