Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, give the circuit theory diagrams of Double-camera velocimeter of the present utility model, it comprises overspeed snapping camera 1, event detection camera 2, circuit part 4, ccd image sensor 4, velocity radar 7, flashlamp 8 and host computer 9; Circuit part 4 is made up of first via image processing circuit 5 and the second tunnel processing of circuit circuit 6.Shown overspeed snapping camera 1, event detection camera 2 are provided with the ccd image sensor 4 light signal being converted into electric signal, and it adopts and focuses mirror group and zoomable, varifocal mirror group respectively.The output of the ccd image sensor 4 on overspeed snapping camera 1 is connected with first via image processing circuit 5, the output of the ccd image sensor 4 on event detection camera 2 is connected with the second road image processing circuit 6, to realize the collection of picture and video information respectively.
The output terminal of velocity radar 7 is connected with first via image processing circuit 5, and the control end of flashlamp 8 is connected with the output terminal of first via image processing circuit 5.Rate signal for measuring the car speed on track to be monitored (two or three tracks), and is sent to first via image processing circuit 5 by velocity radar 7.First via image processing circuit 5 is all connected with host computer 9 by network data transmission interface RJ45 with the second road image processing circuit 6, the image of collection and video data to be sent in host computer 9, realized preservation and the picture monitoring of data by host computer 9.
First via image processing circuit 5 is by the video data on overspeed snapping camera 1 Real-time Collection road surface to be monitored, and by the judgement to the measuring speed that velocity radar 7 is uploaded, when judging to there is overspeed of vehicle, while unlatching flashlamp 8, overspeed snapping camera 1 is utilized to capture multiple high definition pictures of vehicle, to collect evidence to the hypervelocity illegal activities of vehicle, and by hypervelocity illegal picture and real-time monitor video data upload to host computer 9, to carry out processing and preserving.
Second road image processing circuit 6 carries out the detection of the traffic events in monitoring range by event detection camera 2, under normal circumstances, the monitoring range of event detection camera 2 will much larger than the monitoring range of overspeed snapping camera 1, because overspeed snapping camera 1 need obtain the video pictures on corresponding track and capture the vehicle on track, and event detection camera 2 needs to monitor the vehicle illegal in other region or act of violating regulations, as the parking of vehicle on height Emergency Vehicle Lane, vehicle drives in the wrong direction, the event such as to drop of article on vehicle, when the second road image processing circuit 6 judges to exist in its surveillance area traffic offence or violation event occurs, then by controlling zoom and the focusing of event detection camera 2, illegal or vehicles peccancy are carried out amplifying and carries out evidence obtaining of taking pictures.
After second road image processing circuit 6 photographs the enlarged image of traffic offence or vehicles peccancy, be communicated with the video information in the time of one end before and after these illegal activities, be sent in host computer 9 in the lump, together as the evidence of vehicle illegal.Such as, if the second road image processing circuit 6 is by the process to institute's monitor video picture, the 14:05 moment has judged vehicle illegal parking on high speed Emergency Vehicle Lane, then by automatically becoming and focusing on, vehicle region is amplified and vehicle is taken pictures, then the pictorial information of acquisition and the video data in 14:02 to the 14:08 time period are all uploaded in host computer 9, to form the evidence of vehicle illegal parking.
As shown in Figure 2, the Double-camera velocimeter giving utility model is installed on the structural representation on central partition, for speed-limit road section at a high speed, human pilot is having the place of watch-dog not drive over the speed limit usually, but has crossed monitoring overspeed point and then exceed the speed limit, as shown in Figure 2, Double-camera velocimeter is installed in central partition 11, not only can realize velocity survey accurately, but also not easily be found, stop the idea of leaving things to chance of human pilot.
As shown in Figure 3, Double-camera velocimeter of the present utility model is installed on the structural representation on portal frame, Double-camera velocimeter is arranged on portal frame 12, be conducive to overspeed snapping camera 1 and event detection camera 2 forms the good visual field, be more conducive to the monitoring of hypervelocity, road surface real-time pictures, traffic events.
