模拟路标识别及其FPGA实现

Simulated Road Sign Recognition and its FPGA Implementation

针对路标信号的多变性给驾驶员行车途中带来诸多隐患,提出了基于FPGA辅助驾驶中的模拟路标识别系统,该系统实现了实时检测和识别路标信号,并将识别结果显示出来,以便驾驶员做出相应的响应,在一定程度上维护了交通安全。实验结果表明,基于硬件编程语言Verilog设计的硬件电路可快速、稳定地对图像进行二值化处理,且该系统可实现识别向左、向右、禁止停车、禁止通行4种路标,对辅助驾驶系统的研究具有一定的意义。

Complex road signs pose hidden dangers to drivers. A simulated road sign recognition system is proposed for FPGA-based auxiliary driving to offer real-time detection and identification of road signs and signals for the driver to respond appropriately. Experimental results show that the hardware circuitry designed using Verilog realizes fast and stable image binarization processing. The system can identify the four signs of Left, Right, No Parking, and No Entry.
