基于TMS320DM642的嵌入式实时图像处理系统设计及应用

构建了基于TMS320DM642的嵌入式实时图像处理系统，实现了多通道实时图像采集、实时视频图像处理、视频输出等功能，同时具备报警显示功能。该系统应用于智能车辆检测，并在高速公路上进行上车试验。实验证明，该系统不仅能够满足实时图像处理的需要，而且能够准确的检测出车辆目标并且计算目标车辆和本车的距离，如有追尾的危险时，本系统可发出声光报警提醒驾驶员注意，有效的预防高速公路车辆追尾事故的发生。

The design and application of embedded real-time image processing system based on TMS320D M642

A embedded real-time image processing system based on TMS320DM642 was designed in this paper. The system has function of real-time multichannel image collecting, real-time image processing, image output and so on.It also has the function of alarm and display. The system was applied in intelligent vehicle detecting, and we did the experiment in high way. It proved that the system not only satisfied the need of real-time image processing, but also could detect the target of vehicles and calculate the distance of the target correctly. If it is endangered, system can send out acousto-optic alarm to remind the drivers. The system also can prevent the accident effectively in hish way.
