摘要
针对目前图像处理系统传输速率高、数据量大的特点,提出了一种实时图像采集模块设计方案。该模块以TI公司的TMS320DM642数字信号处理器为中央处理器。视频采集采用飞利浦公司的SAA7115,采用CCD摄像头控制采集现场图像数据。给出了硬件接口、软件流程及总线控制等设计。系统做了初步测试,能基本实现实时图像采集。
Aiming at processing image data more efficiently.A hardware design of image capture is provided with TMS320DM642 as the central processor with SAA7115 as its video capture chip and using CCD camera to capture image data.The hardware principle graph of system,software flow chat,video capture chip SAA7115 and their interfaces are given.It is proved the system can work steadily and efficiently.
