摘要
利用ADI公司的DSP评估板,结合数字图象处理技术,设计出了一套实用的车道偏离检测系统平台。该系统采用两个CMOS摄像头采集图像信号,输入到DSP评估板中,先利用图像平滑技术滤除噪声,然后采用边缘检测技术识别出车道识别线,结合速度传感器、转向传感器的信号判断汽车是否将要偏离跑道,在LCD模块中,并实时显示车的偏离状态。如果将要偏离或者已经偏离,就会有蜂鸣震动提示。
A set of practical lane departure detection system platform is designed by using ADI's DSP evaluation board, with digital image processing technology. The system uses two CMOS camera to acquire image signal which will be input into the DSP evaluation hoard. Firstly, the system filters out noise by the image smoothing technology, and identifies lane identification line by the edge detection technology. Then, it will decide if the vehicle will or has departed the lane with the signals of the speed sensor and the turning sensor. The LCD module displays the real-time image. If the vehicle has deoarted the lane. there will be vibrating alert heen.
