A kind of intelligent transportation violation information harvester and acquisition methodTechnical field
The present invention relates to technical field of traffic control, and in particular to a kind of intelligent transportation violation information harvester and collectionMethod.
Background technology
At present, technology of Internet of things is widely applied in intelligent transportation field, and the efficiency for bringing non-at-scene law enforcement is bigBig raising, the intelligent traffic monitoring system for being simultaneously based on technology of Internet of things are continuously emerged as emerge rapidly in large numbersBamboo shoots after a spring rain.Intelligent transportation is supervisedControl system is an important subsystem of wisdom traffic, plays an important role in the construction of smart city.With Chinese societyMeeting rapid development of economy and individual wealth increase, and the volume of holding of motor vehicle is also being sharply increased, although China is devoted to alwaysTraffic route constantly extends and widens, but Current traffic infrastructure construction and traffic law popularization all relatively lag behind, and road is handed overLead to crowded, traffic accident to take place frequently, the phenomenon such as continuous deterioration of traffic environment becomes the theme of the current lives of the people, road traffic is pacifiedThe solution of congruent problem seems severe and urgent.Statistics shows that more than 80% traffic accident is not observed to hand over by driverCaused by poker example.Various break in traffic rules and regulations events how are effectively monitored, the efficiency of non-at-scene law enforcement is improved, reduce and preventTraffic accident occurs, and fast and effectively carries out traffic accident treatment, prevents traffic jam, and recording traffic violation event information isBecome one important issue of today's society.
Now, various intelligent transportation function systems or equipment are used widely in traffic monitoring region, are to improve meState's intelligent traffic administration system level provides strong technology and product is supported.Intelligent traffic monitoring system be using advanced signalDetection means obtains traffic related information, forms effective traffic control scheme by effective traffic control model, with multipleMode transmission information, makes traffic control equipment or administrative staff and the user of road obtain road information and traffic administration sideCase, finally can play transport and the efficiency of management of whole traffic system to greatest extent.
With respect to the traffic surveillance and control system for adopting extra monitoring device, it is current intelligence using traffic video image is directly processedThe developing direction of energy traffic surveillance and control system.It is acquired to traffic video stream by video camera, then using computer videoImage procossing and mode identification technology are processed to continuous traffic video stream and are analyzed, so as to reach monitoring break in traffic rules and regulations rowFor purpose.This mode has simple installation, does not destroy road surface, is protected from weather influences, and arranges flexibly, and monitoring project is many, coversLid scope is wide, the advantage such as accuracy of detection height.With the development of computer hardware technique, video frequency graphic monitoring mode will becomeMainstream technology in intelligent traffic monitoring system.
Existing patent document CN102024330A disclose a kind of based on the intelligent traffic signal control system of HD video,Method and apparatus, disclosed in the literature in method and apparatus, but is merely able to realize for prison during running red light for vehicle signalControl, and when signal lamp is for green light signals state, monitoring main frame just will not gather green light signals data, can not realize forThe monitoring of green light behavior rushed by vehicle；Secondly because signal lamp data and vehicle peccancy driving information data should not be while from monitoring mastersMachine and HD video are obtained respectively, and during proof, convincingness is also not easy to be recognized；Again, the technical scheme adopts digital cameraThe vehicle for travelling is monitored etc. monitoring device, due to line fault, is artificially blocked and is destroyed, the unexpected change of fixing camera positionThe reasons such as dynamic, weather conditions occur that the video signal quality that camera acquisition is arrived is not good, and brightness or noise can not meet and regardThe requirement of frequency analysis.
Existing patent document CN10252983A disclose a kind of vehicle peccancy monitoring system based on high-definition video technology andMethod.In the publication in disclosed system and method, still continue to use and take video to be sent on main frame to be analyzed, do not haveVideo flowing is analyzed in real time, real-time processing；Secondly, the technical scheme will carry out defeated to some informations parameter of traffic intersectionEnter, more complicated；Again, the peccancy detection project that the technical scheme is realized is still more single, simply realizes making a dash across the red light and rushingThe acquisition of green light violation information, fails to reach intelligentized purpose.
Existing patent document CN102622886A discloses a kind of vehicle peccancy lane change event detecting method based on video；Existing patent document CN102622884A discloses a kind of vehicle peccancy based on tracking and turns around behavioral value method；Existing patentDocument CN102768800A discloses a kind of motor vehicle red light violation evidence collecting method based on HD video；Etc..These textsIt is to obtain high definition video steaming using video camera to offer all, analyzes and processes through computer video, single act of violating regulations is supervisedKeyholed back plate is managed, and the service efficiency of monitoring device is low, does not truly realize the intellectuality of break in traffic rules and regulations monitoring management.
