摘要
车道线检测系统是车道偏离预警装置(LDW)的核心。本文基于Xlinx的Spatran6平台,开发了LDW产业化所需的车道线检测算法和现场可编程门阵列(FPGA)电路,并通过软硬件协同仿真验证了系统性能。测试结果表明,该系统进入跟踪模式后,常规路况下识别准确率达100%,实时处理速度不低于30帧/s,能够适应弯道、夜间等工况,可以满足LDW的产业化要求。
The lane detection system is a key part of lane departure warning（LDW）systems. A lane detection algorithm and a field programmable gate array（FPGA） circuit were developed for mass production of LDW systems based on Spatran6 platform of Xlinx. The performances were validated by hardware/software co-simulation. The results show that the detection accuracy is 100% at normal conditions for tracking mode. The real time processing speed is more than 30 frames/s, which can be used under dark and curve driving conditions. The proposed system is satisfied for mass production requirements of LDW systems.
