摘要
本文主要讨论微机图象处理的图象输入的硬件系统.与一般的图象输入系统不同之处是,本系统用价格便宜、性能可靠的录相机代替了磁带机作为记录与回放设备.下面以超声电视测井系统为背景来说明系统的构成.图1是系统框图.从录相机中回放的图象数据经放大整形、同步提取后经接口电路输入微机.由于放大整形及同步提取已在另文中介绍,所以本文仅讨论接口电路的设计.
With an ultrasonic borehole televiewer system as the background, the hardware design of interface for a video-recorder-microcomputer image processing system is discussed.This system is characterized by two sets of memories working alternately. Hence the time for data input to the computer is greatly shortened. Experiments show that the design is feasible and the system performance is satisfactory.
