Description
Technical field
The present invention relates to a kind of intelligent side snapping system for rule-breaking vehicle.
Technical background
The capturing system that is used for the traffic violations supervision generally includes video camera and the vehicle speed detector device that is used to capture, red light pick-up unit and central control unit, obtain speed information by vehicle speed detector device, the red light pick-up unit obtains red light information, by central control unit these information are handled, judge the unlawful practice whether vehicle exists hypervelocity and make a dash across the red light, and the violation vehicle captured shooting, the candid photograph direction of capturing at present video camera all is (this to) consistent with vehicle heading basically, minority opposite with vehicle heading (oppositely), the illumination preferably under the situation by day of this candid photograph mode, generally can both obtain high-quality picture and/or video segment, but under cloudy day and the bad situation of light at night, because background is too dark, it is very big that the relative brightness of red light will become, large-area dazzle can appear on picture that this moment, forward was filmed and/or the video segment, vehicle identification number is unintelligible even can't offer an explanation, if as the law enforcement foundation, its conviction property will be had a greatly reduced quality with this.Therefore, the applicant according to existing video camera particularly high speed one spherical camera (can abbreviate the ball machine as) take characteristic, various candid photograph modes have been carried out a large amount of experiments, discovery is under the mode that side direction is taken, can reduce the red light dazzle under the situation of background dim light significantly, obtain high-quality picture and/or video segment, propose the technology of side direction grasp shoot, adopt the side direction video camera to carry out the candid photograph of vehicle in violation of rules and regulations, eliminated dazzle capturing the influence of image.But, existing this technology has only single default Maximum speed limit, because according to existing regulation, for the higher road of many Maximum speed limits, Maximum speed limit will descend significantly when foggy weather occurring, and existing capturing system can't obtain the situation of change of this Maximum speed limit, still carry out the monitoring of overspeed of vehicle according to the Maximum speed limit under the normal condition, cause many over-speed vehicles not to be found, influenced driving safety, particularly on highway, owing to can't control car speed under the inclement weather such as dense fog by effective means, often to cause serious blocking up directly with the highway sealing.
Summary of the invention
For overcoming the defective of prior art, the invention provides a kind of intelligent side snapping system for rule-breaking vehicle, this control system not only can realize the effect of side direction grasp shoot, eliminate the red light dazzle to capturing the influence of picture quality, but also can be according to the variation of weather, automatically discern weather condition, Maximum speed limit is set on the corresponding setting of weather condition, changed the situation that the Maximum speed limit of big greasy weather system's Maximum speed limit and regulation is not inconsistent thus, realized monitoring effectively over-speed vehicles.
The present invention realizes that the above-mentioned purpose technical scheme is: a kind of intelligent side snapping system for rule-breaking vehicle, comprise the side direction grasp shoot device, vehicle speed detector device, visibility pick-up unit and central control unit, described side direction grasp shoot device is made up of to video camera plurality of side, each side direction video camera carries out the candid photograph of respective direction according to the instruction of described CPU (central processing unit), obtain the video image of over-speed vehicles and send into described CPU (central processing unit), described vehicle speed detector device is used to obtain vehicle speed data, described central control unit receives this vehicle speed data, and it is compared with Maximum speed limit, when actual vehicle speed during greater than Maximum speed limit, judge overspeed of vehicle, and the video camera of instruction grasp shoot device is captured, described CPU (central processing unit) is to the video image analysis computing of over-speed vehicles, obtain the number-plate number of over-speed vehicles, described visibility pick-up unit is used to gather the visibility data, and deliver to described CPU (central processing unit), described CPU (central processing unit) reads the Maximum speed limit data corresponding with the classification visibility range that prestore, and with this as the Maximum speed limit of judging whether vehicle exceeds the speed limit.
Because the present invention has adopted the side direction grasp shoot device, not only overcome long-term puzzlement people's red light glare problem, avoided the red light dazzle to capturing the adverse effect that image produces, guaranteed to capture the quality of image, and by being provided with the visibility pick-up unit, can obtain the visibility data in real time, thus on the different road of the different Maximum speed limits of visibility, CPU (central processing unit) can be according to the data of visibility, find out corresponding Maximum speed limit data, make real judgement so that whether vehicle exceeded the speed limit, avoid because of not changing failing to report that Maximum speed limit brings in real time at the lower weather of visibility.
