为了解决因疲劳/瞌睡驾驶而造成的交通事故,研究了各种疲劳检测算法。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AD,DSP器件TMS320DM642为核心处理器,SAA7105为视频输出DA,利用FPGA控制输出,以实现增强显示功能的实时视频处理系统。该系统可以满足多路视频的实时采集、处理、显示的需求,可以作为疲劳检测算法的硬件平台,同时也可以作为视频处理、图像处理的硬件平台。
In order to resolve crashed accidents caused by fatigue or drowsiness various fatigue detecting algorithms are investigated. Aiming at the needs of large data, high transmission speed and complex operation, a real-time video-based processing system using SAA7.115 as its capture AD, TMS320DM642 as its core, SAA7105 as its display DA ,is designed, and FPGA is used to control the display to achieve advanced function. The system can meet the needs of capture, processing and display of multi-channel video. Furthermore, it can be used as a video and image processing platform.
