Abstract:In view of the current car in A mixed road condition queuing time problem, designed and implemented A hybrid road condition of auto intelligent routing system based on single chip microcomputer, the system adopts photoelectric sensor for auto speed and distance measurements, using CCD camera to obtain A road car operation image video image, using SAA7113 video decoder by anti aliasing filter, A/D converted into digital images stored in the high performance computer, intelligent route choice is introduced into the between-cluster variance algorithm (OTSU) according to the vehicle and background variance of dynamic image segmentation threshold is determined, get queued vehicle image region, according to the video time for queue waiting time of the vehicle information. And to obtain the data information analysis and processing, finally realizes the auto time optimal path or road shape optimal choice. Experimental results show that the system choose the path of the vehicle queuing time and optimal waiting time matching degree reached 98%, error control within 2.5%, and the system has high stability, broad application prospect.
