Description

Fixed intersection monitoring system

Technical field

The invention belongs to the supervisory system technical field, particularly a kind of fixed intersection monitoring system.

Background technology

Utilize technological means to realize strong improvement is carried out in the driving against road traffic regulation behavior, can effectively prevent this type of break in traffic rules and regulations behavior, reduce the accident that causes thus, can play very big deterrent effect to driver violating the regulations again, promote traffic order to benign cycle, while can be separated the part traffic police and be put down from the sentry box, alleviate the contradiction of police strength deficiency to a certain extent, the real infinite strength from police strength to science and technology that want that embodies.

In the research and development of electronic police system solution, though more existing successful stories, but these products all are by setting up monitoring violating the regulations and the hypervelocity system that deploys to ensure effective monitoring and control of illegal activities, the management that realization is carried out the information of real time monitoring, candid photograph, warning, recorded and stored vehicle pass-through and vehicle flowrate data and concentrated vehicle current in the guarded region on the road, but to monitoring track all-weather registration of vehicle licence plate and vehicle panorama characteristic image, sensing range is smaller, and catch rate and picture show that Chinese character, letter, number intelligibility are lower.The ordinary electronic policing system solution system information processing function is not really powerful, the system extension inconvenience, and the storage of picture is also undesirable, and under a lot of situations such as weather, light, the vehicle pictures naked eyes can not be distinguished its vehicle characteristics.

The time that is embedded in the parallel inductive coil of road below according to the vehicle process is calculated the moment violating the regulations, judges whether to break rules and regulations, and camera shooting evidence-obtaining.The shortcoming of this detection method is to be that ground buries the great in constructing amount of inductive coil underground, in case road surface change then the circle of need heavily sunkening cord, the high latitude bad place of phase and low latitude road surface in summer and pavement quality of thawing all is huge to the maintenance work of coil in addition.

Summary of the invention

The invention provides a kind of precision height, wide ranges, captured target standard, sharpness height, flexible operation, adaptable fixed intersection monitoring system, use this invention can be under city intersection unmanned situation, driver's act of violating regulations comprised make a dash across the red light, one way traffic drives in the wrong direction, hypervelocity etc. is carried out long-term uninterrupted automatic judgement and image recording, and image and violation information real time remote is transferred to Surveillance center.

A kind of fixed intersection monitoring system, comprise hardware components and software section, described hardware components comprises three video cameras and a crossing industrial computer (for two-way traffic) that is arranged on the portal frame of crossing, the central server that described crossing industrial computer signal connects, described three video cameras comprise two close shot video cameras and a distant view video camera, described video camera is connected with crossing industrial computer signal, described software section comprises that image keeps in module, the digital transmission module, image processing module, trigger module and database module, described trigger module touches video camera according to the traffic violations situation and carries out image acquisition and violation information record, the image information that collects is temporary by the temporary module of image, and image acquisition and violation information are transferred to central server by the digital transmission module, after described image processing module processing, together enter database module with violation information.

Described trigger module comprises two virtual coils, be arranged on the position of vehicle generation act of violating regulations on the image, when a certain direction is red light, according to virtual coil condition is set, detect vehicles peccancy, panorama and corresponding feature video camera violating the regulations are captured 1 Zhang Quanjing and 2 features, constitute violating the regulations true.

Fixed intersection monitoring system mainly adopts digital image processing techniques, with high performance industrial control computer system is core, adopt the high-resolution digital camera photographic images, adopt technology such as electromagnetic induction, Computer Image Processing, digital communication, database, under city intersection unmanned situation to driver's act of violating regulations (comprise make a dash across the red light, one way traffic drives in the wrong direction, hypervelocity etc.) carry out long-term uninterrupted automatic judgement and image recording, and image and violation information real time remote are transferred to Surveillance center.Law enforcement agency can punish driver violating the regulations according to profile, the license number of the vehicle that document image provided.This system has remedied traditional optical camera photo and can not transmit and ccd video camera sharpness deficiency on the low side.Adopt between the variable region and the multiple strategy of vertical and horizontal, improve the accuracy rate of capturing; Adopt intelligent image identification treatment technology, not only improved accuracy rate but also improved confidence level, increase the extraneous adaptive faculty of system simultaneously.Adopt high explanation acquisition technology, have continuous candid photograph ability.In observation process, adopt gray-scale map effectively, greatly improved the reaction velocity of system.Adopt panorama to combine, make illegal vehicle information record more abundant with focusing.The multi-usage pattern arbitrarily is provided with control mode by use occasion.Disobey the barrier record and adopt computing machine picture and text management mode.Adopt the digital camera shooting technology, on the storage card of photo storage in camera, can use repeatedly.
