摘要
本文介绍了基于DSP的驾驶员疲劳瞌睡检测系统,详细介绍了以SAA7115为视频采集A/D、DSP TMS320DM642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的硬件平台。本系统具有结构紧凑、调节灵活、计算准确、可靠性高、实时性强的特点。
The article introduced driver weary sleepy detection system based on DSP. The real time video processing system which used SAA7115 as video acquisition A/D, the DSP TMS320DM642 as processor, SAA7105 as out put of video signal was described in detail. The system used the double camera for controlling gathering data, may satisfy the multi-charred video＇s requirements where were real-time gathering, disposing and displaying showing, may be used to be the hardware platform of the weary detection algorithrm. The system has many characteristics, such as close structure, agilely adjusting, accurately calculating, strong real-time.
