摘要
研究了运动图像的实时采集方法，提出采集系统的工作原理及主要时序，对各种图像源的信号，都能一次连续采集３２幅１２８×１２８的活动图像，均有满意的结果．实验表明，按本法设计的采集板有良好的实时性，通用性强，成本低，可适合ＩＢＭＰＣ及兼容计算机，应用范围广。
A method for real time acquisition of moving images is studied and the design of hardware and software of the acquisition system is described. The hardware consists of real time preprocessing, front end timing, frame memory and interface. The functions of reading, displaying and printing are contained in the software. The principle and main working time sequences of the components are discussed. 32 moving images of 128×128 Bytes from various signal resources can be acquired each time with satisfactory results. Experiments show that the acquisition board designed has good real time performance and a wide range of application. It is cost effective and can be used on an IBM/PC or a compatible computer while promising expansion for acquisition of 64 images or even more.
