摘要:

针对现今采用PC机实现的车道偏离预警系统实时性低的问题,介绍了一种以FPGA为核心的车道偏离预警系统的纯硬件语言实现方法。整个系统由纯硬件语言设计,主要包含图像采集模块,中值滤波模块,Sobel边缘检测模块和Hough变换模块。每个模块均采用并行结构同时系统以流水线方式运行,充分利用了FPGA的并行处理优势,显著的提高了数据处理的速度。结果表明,系统边缘检测效果良好,能清晰地检测出车道线;同时系统响应速度满足实际需求。

关键词: FPGA, 并行处理, Sobel边缘检测, Hough变换

Abstract:

In order to,a system based on FPGA is proposed for improving the speed of a rapid lane departure warning system based on PC.The whole system consists of several modules including the median filtering module,the Sobel edge detection module,and the Hough transform module.Each module is achieved by using Verilog HDL Language and designed in the way of parallel structure so as to make full use of the super power in parallel processing of the FPGA.The system is demonstrated to be fast enough to detect the lanes departure and applicable in daily life.

Key words: FPGA;parallel processing;Sobel;Hough transform
