摘　　要：针对疲劳检测算法中大数据量、高速传输、复杂运算的实际需要,设计了以SAA7115为视频采集A/D、DSPTMS320DM642为核心处理器、SAA7105为视频输出D/A,并以FPGA控制输出来实现增强显示功能的实时视频处理系统。该系统采用双摄像头控制采集数据,可以满足多路视频的实时采集、处理、显示需求,可以作为疲劳检测算法、视频处理和图像处理的硬件平台。Aiming at the needs of large data, high transport and complex operation, a real-time videobased processing system using SAA7115 as its capture A/D, TMS320DM642 as its core,SAA7105 as its display D/A ,is designed, and FPGA is used to control the display to achieve advanced function. The system using two cameras to capture image data can fulfil the demands of capture, processing and display of multi-channel video. Furthermore, it can be used as the video and image processing platform.
