Description
Technical field
The present invention relates to technical field of traffic control, and in particular to a kind of intelligent transportation violation information harvester and collection
Method.
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 big
Big 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 supervised
Control system is an important subsystem of wisdom traffic, plays an important role in the construction of smart city.With Chinese society
Meeting 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 always
Traffic route constantly extends and widens, but Current traffic infrastructure construction and traffic law popularization all relatively lag behind, and road is handed over
Lead 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 pacified
The solution of congruent problem seems severe and urgent.Statistics shows that more than 80% traffic accident is not observed to hand over by driver
Caused 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 prevent
Traffic accident occurs, and fast and effectively carries out traffic accident treatment, prevents traffic jam, and recording traffic violation event information is
Become 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 me
State's intelligent traffic administration system level provides strong technology and product is supported.Intelligent traffic monitoring system be using advanced signal
Detection means obtains traffic related information, forms effective traffic control scheme by effective traffic control model, with multiple
Mode transmission information, makes traffic control equipment or administrative staff and the user of road obtain road information and traffic administration side
Case, 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 processed
The developing direction of energy traffic surveillance and control system.It is acquired to traffic video stream by video camera, then using computer video
Image 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 row
For purpose.This mode has simple installation, does not destroy road surface, is protected from weather influences, and arranges flexibly, and monitoring project is many, covers
Lid scope is wide, the advantage such as accuracy of detection height.With the development of computer hardware technique, video frequency graphic monitoring mode will become
Mainstream 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 signal
Control, and when signal lamp is for green light signals state, monitoring main frame just will not gather green light signals data, can not realize for
The 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 masters
Machine and HD video are obtained respectively, and during proof, convincingness is also not easy to be recognized；Again, the technical scheme adopts digital camera
