适用于导弹及武器控制系统的具有自动跟踪能力的各种视频信号处理技术已经研制出来。特别令人感兴趣的是那些既能和实时成像系统联接,又适合于标准电视制式的技术。 本文首先介绍自动电视跟踪装置的功能及其结构,然后对电视自动区域跟踪装置的原理及应用进行深入地讨论。文中介绍了由光栅扫描信号综合出跟踪特征信号的技术。也介绍了将实时跟踪特征信号和存储的参考特征信号加以比较,从而得出跟踪误差的算法,并用实验数据举例加以说明,另外,还讨论了由距离闭合误差引起的传感器扫迹变化对跟踪精度的影响,以及减少这些误差的方法。
Various video signal processing technologies with automatic tracking capability for missiles and weapon control systems have been developed. Of particular interest are those that are compatible with both real-time imaging systems and with standard television formats. This paper first introduces the function and structure of automatic TV tracking device, and then discusses the principle and application of TV automatic area tracking device. In this paper, we introduce the technology of tracking the characteristic signal by raster scanning signal. The algorithm of comparing the real-time tracking characteristic signal with the stored reference characteristic signal is also introduced to derive the tracking error. The experimental data are used to illustrate the algorithm. In addition, the variation of the tracking error The impact, and ways to reduce these errors.
