基于信号注入仿真的红外成像导引算法评估系统

在红外成像导引算法性能评估中,信号注入式仿真不用将真实导引头引入闭合回路。计算机成像系统模拟战场环境,产生包含目标、背景和干扰的红外图像源,通过视频输出接口注入到图像处理器,图像处理器按照成像导引头的工作方式,对目标进行捕获跟踪。以反舰导弹为仿真对象,介绍了系统的构成,阐述了以提取天水线为准则的图像分割算法和模糊综合评判目标识别算法,分析了形心和相关两种跟踪算法的适用场合和工作过程,最后给出了评估准则。

An Evaluation System of Infrared Imaging Guiding Algorithm Based on the Signal Injection Simulation

In the evaluation of the infrared imaging guiding algorithm, the signal injection simulation doesnt take the actual guider into the loop. The computer image generation system (CIG) simulates the battlefield. Series of infrared images which include the target, background and interference are generated by the CIG, then are injected into the image processing unit (DSP) with the video out interface. The DSP acts as the guider to simulate the guider to detect and track the target. The consistence of the system was introduced. The sea-sky line was picked up to divide the image. The fuzzy synthetic judging method had been used to recognize the target. Two tracking algorithm, relative and centroid, had been compared with each other. In the end, the evaluating principle was introduced.
