摘要/Abstract

摘要： 研制了一种在线快速错帖检测系统。该系统的硬件部分使用了TM320DM642处理器，通过EPMA方式实时获取CCD摄像头的N制式图像，外扩了FLASH、SDRAM存储器、CPLD作为逻辑控制器。硬件部分还带有键盘和液晶屏等外部设备。错帖检测算法采用灰度相关的方法固化在FLASH中。该系统实时检测文字、图形帖中存在的错误书帖。实验表明，该系统检测精度约为99%，具有较好的检测稳定性和准确性。

Abstract: In this paper，an online fast video system for page checking is developed.The hardware of this system is with the application of TM320DM642 video processor，and it obtains CCD video N type image real time by the mode of EPMA.In this system，it extends FLASH，SDRAM memorizers，and uses CPLD as logic controller as well.In addition，it has other keyboard and screen peripheral equipment.A detecting algorithm developed via image recognition theory is stored in FLASH.This system detects dynamically wrong pages located in many word pages，graphic pages.Experiments show that precision of this wrong page-detecting system is about 99% and it posses fine stability and veracity.
