摘要
为了达到比较理想的预警效果,对基于视觉的车道偏离预警系统进行了研究,开发出一套基于车载环视驾驶辅助系统的车道偏离预警系统。通过环视系统获取车辆的俯视图像,然后采用适当的图像预处理方法和有效的车道线边缘检测算法,快速的对车道标志线进行识别和定位,最后基于TLC(time to lane crossing)预警算法,建立了一套完整的车道偏离预警系统。实验结果表明:该系统具有较好的可靠性和实用性。
In order to get an ideal warning effect,lane departure warning system based on machine vision is studied and a lane departure warning system based on surround view assistance system is developed. Through the surround view system,get the overlooking images of vehicle,then by means of proper pre-processing and effective lane line edge detection algorithm, the lane edge is recognized and located. Finally, based on TLC warning algorithm, one complete lane departure warning system is established. The experiments results show that the system has good reliability and usability.
