Abstract
The invention discloses a highway traffic information collection system in the highway monitoring field. The highway traffic information collection system comprises a camera unit installed on a highway. The signal output end of the camera unit is connected with the signal input end of a video processor through an optical fiber; the signal output end of the video processor is connected with the signal input end of a data server; and the data server is connected with a client end. The camera unit comprises a CCD camera and an optical transceiver. The highway traffic information collection system can process traffic video information in real time, and can obtain some basic traffic information of traffic flow, vehicle speed, traffic jams and road occupation rate and the like effectively; and system is tested on the traffic scene, and the result shows that the system has good real-time performance and reliability, and can be used for the management of the highway.
Description
Technical field
The present invention relates to a kind of highway monitoring system, particularly a kind of freeway traffic information acquisition system.
Background technology
In time, effectively gathering Traffic Information (flow, the speed of a motor vehicle, occupation rate, vehicle etc.) is a key link that realizes intelligent transportation system ITS (IntelligentTrans-portationSystem).At present, have for the most frequently used mode of acquisition of road traffic information: buried inductive coil, microwave, ultrasound wave, global positioning satellite (GPS), video detection etc.Wherein, video detects compared with the detection mode conventional with other and has the following advantages: (1) can provide more direct traffic scene.(2) sensing range is large, and available traffic parameter is many.(3) install, easy to maintenance, road pavement ground without damage etc.In addition, along with the development of the technology such as computer hardware technique and image processing, artificial intelligence, pattern-recognition, real-time and accuracy that video detects have reached more satisfied degree, just receiving traffic operation, administrative authority and researchist's concern, and be applied in actual traffic administration, information acquisition system weak point of the prior art is, is transferred to rate server slower after video information collection, can not obtain in time corresponding data.
Summary of the invention
The object of this invention is to provide
The object of the present invention is achieved like this: a kind of freeway traffic information acquisition system, it is characterized in that, comprise the image unit being arranged on highway, the signal output part of described image unit is connected with the signal input part of video processor by optical fiber, the signal output part of described video processor is connected with the signal input part of data server, on described data server, is connected with client.
As a further improvement on the present invention, described image unit comprises ccd video camera and optical transmitter and receiver, and the signal output part of described optical transmitter and receiver is connected with video processor.
When the present invention works, system gathers the video information at traffic route scene by ccd video camera, be transferred to video processor VIP (VideoImageProcessor), video processor carries out the information of vehicles in Treatment Analysis detection and tracking video information to video information, and then according to the actual requirements the result of detection and tracking is processed, obtain corresponding traffic parameter, traffic parameter is transferred to data server simultaneously, offer traffic control platform and use.Compared with prior art, beneficial effect of the present invention is, the present invention can process traffic video information in real time, effectively obtain some basic transport information such as vehicle flowrate, the speed of a motor vehicle, traffic jam and roadway occupancy, by system being tested at traffic scene, result shows, system has good real-time and reliability.The present invention can be used in the management of highway.
Brief description of the drawings
Fig. 1 is control principle block diagram of the present invention.
