一、引言图象处理一般都使用CCD摄象机,其实用例子也日益增多.不过,用于图象处理的CCD摄象机大多采用RS-170标准的摄象机,每秒只能拍摄60幅图象.可是近年来迫切需要在1/60秒期间内分析不能捕获到的高速瞬变现象.根据这种需求,美国Reticon公司推出混合式摄象机.这种混合式摄象机扫描速率可调,从低速到高速扫描可灵活调节.尤其是高速扫描,采用128×128象素全帧扫描时,最多达380帧/秒.而且,利用跳越扫描功能,假若缩为一行的话,则可实现8000帧/秒.本文将介绍混合式摄象机的特点,跳越扫描专用控制器以及自动跟踪之应用实例.
I. INTRODUCTION Generally, CCD cameras are used for image processing, and practical examples are also increasing day by day. However, the CCD cameras used for image processing mostly use the RS-170 standard camera and can only shoot 60 However, in recent years, there is an urgent need to analyze high-speed transients that can not be captured within 1 / 60th of a second. According to this demand, the United States launched a hybrid reticon camera. This hybrid camera scan rate Adjustable, from low to high speed scanning can be flexibly adjusted. Especially high-speed scanning, with 128 × 128 pixel full-frame scanning, up to 380 frames / second. And, using the skip scan function, if reduced to one line, then Can achieve 8000 frames / sec.This article will introduce the characteristics of hybrid cameras, skip the dedicated controller and automatic tracking application examples.
