中文摘要：

该文提出了一种并行的快速车道线检测系统。该系统包含一个32×32的处理器单元（PE）阵列和双RISC子系统。PE阵列实现车道线图像像素级并行预处理,获取图像边缘特征,双RISC核子系统根据边缘特征实现两条车道线直线参数的并行检测,从而使得检测过程的每一步都是并行进行,显著提高检测速率。该系统用FPGA实现。实验结果表明本系统具有良好的鲁棒性且可达到每秒50帧的检测速率,满足了车道偏离预警系统实时性要求,具备重要的应用价值。

英文摘要：

This paper proposes a parallel fast traffic lane detection system. The system consists of a 32×32 Processing Elements （PE） array and a dual RISC core subsystem. The PE array performs pixel-parallel image preprocessing and outputs edge features, the dual RISC core subsystem performs two lanes parameters detection in parallel based on edge features. In this way, every step in the detection process is in parallel and the detection rate is rapidly increased. The system is implemented with FPGA. The experiment shows that it has good robustness and can reach up to 50 fps. This meets the demand of real-time for lane departure warning system and makes an important sense for practical application.
