基于嵌入式系统的图像采集系统

Image Collection System Design Based on Embedded System

介绍使用Freescale公司MC9S12XS128单片机通过中断功能,控制OV7620摄像头采集图像并利用上位机软件在pc上显示的设计过程。硬件上使用XS128单片机为主控系统,利用OV7620数字摄像头采集图像;软件上用单片机中断功能控制行场扫描,采用隔行扫描的方式采集图像。

This paper introduces how to use MC9S12XS128 microcontroller of Freescale company, by interrupting function, to control OV7620 camera and use the PC software to acquire images in the PC. Then images are displayed on the design process. In hardware,one can use XS128 microcomputer as the master control system, use the OV7620 digital camera to acquire images; and in software, one can use the microcontroller＇s interrupt function to control line field scans, and use frame - rate way to collect images.
