Research And Design Of Red Light Runners Recorder Based On Video Detecting

As the global economy develops at a high speed,the number of car in cities increases rapidly,traffic jam becomes more and more seriously,monitoring the state of road traffic in real time has been significant for us to collect traffic information, standardize the management of traffic ,city layout and so on。Here, combining the task "Redlight runner recorder based on video technology"cooperated with Jing'an Corp. in Guangdong province, after analyzing respective strongpoint and shortcoming of some video detecting methods, two kinds of ideas are put forward, and then an effective algorithm of peccancy surveillance based on video technology is brought forward to settle this problem. Practical result validates the algorithm. The method of vehicle peccancy surveillance is usually achieved through inductor buried in the ground or axle sensor. This will damage the road surface, and bring much inconvenience for construction and fitting. Also they often need to be examined and repaired, all these bring lots of inconvenience. Here a method based on video technique is employed, and a new concept of loop detector which we call it virtual loop is brought forward for traffic surveillance instead of the old one which buried in the ground. The thesis explains the structure , the function of "Redlight runner recorder based on video technology"and questions appearing on program debugging in detail. Experience of accumulation and procedures on testing algorithm under the real environment are especially introduced . Using many kinds of video detection technique synthetically , problems of miscarriage and escape of justice resulting from such as car headlight and environmental change are solved . Test run shows the cameraing percentage and validity of pictures reach the fixed demand of national standard GA/T 496-2004 . The system is exploited on the flatform of Win2000 with C/C++ language, its setting up deals with image process, multithreading, GPRS and serial port communication and so forth, all the parts work in line to bulid a banausic and steady system.
