| Abstract: | Based on TMS320DM642 DSP,video processing technology and wireless transmission technology,an embedded obsta-cle alarming system aimed at railway monitor was designed in this paper.The overall structure and individual modules of the sys-tem 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. |
