摘要
基于TMS320DM642 DSP、视频处理技术和无线传输技术设计并实现了一种嵌入式铁路路障视频报警系统。给出了系统的总体结构和各个组成模块,分析了图像采集、图像处理和无线报警部分的具体功能。采用基于Canny边缘检测技术和聚合接续法的铁路框架提取方法,实现了铁轨曲线区段的提取。
Based on TMS320DM642 DSP,video processing technology and wireless transmission technology, an embedded obstacle alarming system aimed at railway monitor was designed in this paper. The overall structure and individual modules of the system were introduced in this paper, as well as the specific features of image acquisition, image processing and wireless alarm. By the method of abstraction based on canny edge detection and poly-connection, the abstraction of curve rail-framework was achieved.
