本文介绍了一种嵌入式车载交通标志检测与识别系统的设计与实现。此外，它还讨论了驾驶员辅助技术的最新进展，并强调了智能车载嵌入式系统的安全动机。提出了一种对RGB图像数据进行处理、提取相关像素、对图像进行过滤、标注潜在交通标志并与模板交通标志图像进行评价的算法。描述了一种可重构的硬件系统，该系统使用Virtex-5 Xilinx现场可编程门阵列和软硬件协同设计工具来创建嵌入式处理器和必要的硬件IP外围设备。该实现在时间和精度方面都显示出稳健的性能结果。
This paper presents the implementation of an embedded automotive system that detects and recognizes traffic signs within a video stream. In addition, it discusses the recent advances in driver assistance technologies and highlights the safety motivations for smart in-car embedded systems. An algorithm is presented that processes RGB image data, extracts relevant pixels, filters the image, labels prospective traffic signs and evaluates them against template traffic sign images. A reconfigurable hardware system is described which uses the Virtex-5 Xilinx FPGA and hardware/software co-design tools in order to create an embedded processor and the necessary hardware IP peripherals. The implementation is shown to have robust performance results, both in terms of timing and accuracy.
