Abstract
The invention relates to a capturing method and system for digital video signal and sharp digital picture of breakthrough vehicle. It adopts industrial level digital camera to capture video or picture automatically under working state and could decrease device investing and improve reliability.
Description
Technical field
The present invention relates to a kind of electronic Police Realization Based method and system thereof, especially a kind of electronic police implementation method and system thereof based on digital communication technology, the acquisition methods and the system of specifically a kind of vehicles peccancy digital video signal and high-resolution digital photo.
Background technology
Along with the development with traffic management technology of improving constantly of scientific and technological level, using electronic equipments such as electronic police and electronic cards jaws equipment to monitor road traffic condition automatically in a large number at traffic block port and crossing is a kind of important means that improves traffic management level.Video acquisition wherein, picture catch automatically and automatically storage be wherein key equipment.Equipment in the past adopts simulation camera or video camera to produce the video image of NTSC or pal mode more, and the input computing machine is stored, transmitted and handles after adopting video frequency collection card with the video signal digitization of simulation.There is following shortcoming in this method:
One, video of Chan Shenging and image are same TV signal, and resolution is low.Because no matter be pal mode or TSC-system formula, image all can only reach the level of hundreds of thousands pixel, is difficult to obtain the large-scale picture of the clear degree of high-resolution.This does not still consider the situation under the interleaved situation of TV signal.Because in fact the staggered scanning characteristic of TV signal is poorer for the effect vehicle of running at high speed.
Two, in the transfer process of the transmission of simulating signal and analog to digital signal, the loss of signal is bigger.
Three, each video camera needs a vision cable transmission signals, makes the quantity of signal wire a lot, causes difficulty for construction and maintenance.
Four, the adjustment inconvenience of camera or video camera, such as, parameters such as aperture and time shutter can not be adjusted according to outside light conditions.Just need to use external mechanical hook-up and motor if must adjust automatically, increased the complexity of system like this, increased probability of malfunction, also increased the difficulty of cost, volume and the maintenance of system.Reduced reliability.
Five, catching by the software of computing machine of signal finished, and in order to save often a lot of cameras (having a plurality of multi-channel video capture cards) of computer control of cost, so image acquisition often can not in time be finished.
In view of the above, as can be seen, obtain vision signal simultaneously and in time catch the core that high-quality picture is an all problems.For this reason, have on some traffic monitoring equipment and to adopt video camera to add the mode of digital camera.The core of this method is to adopt analog video camera to provide video information to adopt digital camera to carry out image capturing in addition, produces high-quality image.Owing to needn't produce image from video information, therefore video information can be transmitted after by video switcher again, can reduce the quantity of video transmission line so effectively, simultaneously because digital camera itself often has the USB interface that is connected with computing machine, if obtain the support of camera producer, also can adjust the parameters such as aperture, time shutter, gain of camera with program.The picture of catching can transmit by computer network after entering computing machine.Therefore this scheme is from having solved the deficiency of original system to a great extent.But this method has been introduced new deficiency again:
One, increases digital camera, increased the complexity and the cost of system, reduced the reliability of system.
Two, because this scheme must obtain the support of digital camera producer, therefore often can only use the fixedly digital camera of the fixedly model of producer, otherwise just need write the control program of digital camera again.
Three, because digital camera adopts the USB mouth to be connected with computing machine, and the content of transmission is a picture, data volume is bigger, can not adopt the USB connected mode of low speed, must adopt the USB2.0 high speed protocol to carry out communication, therefore the length of USB cable is subjected to bigger restriction, and the travelling speed of computing machine required also than higher, therefore in this case, often 1 digital camera will be equipped with a PC, handle, so the complexity of system, cost, failure rate all can increase substantially.
Four, most digital cameras all are civil goods, and failure rate is very high under high temperature, low temperature, unattended situation, have therefore also increased system's factors of instability.
Summary of the invention
The objective of the invention is poor reliability at existing electronic police implementation method and system's existence, the problem that failure rate is high, but a kind of all weather operations of invention, reliable and stable vehicles peccancy digital video signal and the acquisition methods and the system of high-resolution digital photo based on digital technology.
Technical scheme of the present invention is:
The acquisition methods of a kind of vehicles peccancy digital video signal and high-resolution digital photo is characterized in that it may further comprise the steps:
The first step is installed a digital camera at road monitoring point, and this digital camera is linked to each other with control computer by connecting bus;
Second step, near installation triggering senser element road monitoring point, and should trigger senser element and link to each other with aforementioned control computer by connecting bus;
In the 3rd step, resolution, aperture, the time shutter of being adjusted road monitoring point video camera by control computer automatically make it to adapt with surrounding environment and be operated in optimum condition;
The 4th step, make digital camera work in the video capture state, when triggering senser element and sense signal violating the regulations, notify control computer immediately, control computer makes digital camera work under programmed control immediately and sends into the control computer storage for calling after the digital camera state is also taken the high-resolution digital photo of vehicles peccancy immediately, after taking end, digital camera changes the video capture state once more under the control of control computer, waits for and triggers conversion next time.Wherein the reserve capacity of video data and time can be according to the requirement of traffic control department by procedure auto-control.
Realize system for carrying out said process, it is characterized in that it is made up of the digital camera that is installed in road monitoring point, the triggering senser element, the control computer that are installed near the road monitoring point, digital camera and triggering senser element link to each other with control computer by connecting bus.
Described triggering senser element can be inductive coil or velocity radar.
Described connecting bus can be 1394 grid lines, industrial field bus or ethernet line.
Beneficial effect of the present invention:
1, adopts single technical grade video camera to carry out video and image acquisition, simplified system and increased reliability, help minimizing equipment input.
2, adopt the collection of digital video and image, reduced because the image loss that transmission and analog-digital conversion bring.
3, can obtain the lower video of resolution and can reach the licence plate picture of millions of pixels of digital camera level simultaneously.
4, the main frame of transmission that adopts bus-network such as Ethernet, 1394 etc. to carry out video and picture can be managed multiple cameras, and need not increase the quantity of plug-in card in the computing machine.System can increase or reduce video camera neatly in needs like this.
5, main frame can directly become the control video camera and gets parameter such as resolution, aperture, time shutter and do not need additionally to increase hardware device, can regulate video simultaneously and the parameter when taking pictures, and makes video and take pictures all to reach optimum efficiency.
