目前,使用电视技术及其相应的仪器对运动目标进行跟踪测量,是国内外科技工作者研究的“热门”课题。如何利用波门对运动目标进行搜索和捕获,乃是其基础技术之一。本文简述了波门搜索目标的各种方式及波门自动搜索运动目标的原理。笔者曾采用简单的电路完成了波门的半自动和自动搜索。本文着重叙述光笔引导波门搜索方式及从左至右、自上而下的搜索方式,并报告其实验结果。 Currently, the use of television technology and its corresponding instruments to track the movement of moving targets, scientists at home and abroad to study the “hot” issue. How to use the gatekeeper to search and capture the moving target is one of the basic technologies. This article outlines the various ways that Borland searches for targets and how Boltzmann searches for moving targets automatically. I have used a simple circuit to complete the wave of semi-automatic and automatic search. This article focuses on the light pen to guide the search method and from left to right, top-down search, and report its experimental results.
