Abstract

The invention discloses a vehicle speed detection system based on video analysis, comprising a video collection module, a GPS positioning module, a communication module, a video pre-analysis module, a central processing unit, a storage module, and an alarm module. The video collection module and the GPS positioning module work synchronously, and are connected with the communication module. The video pre-analysis module receives video information transmitted by the communication module. The central processing unit processes the analyzed video information, classifies and screens the video information and stores the video information in the storage module. The alarm module is connected with the central processing unit. Compared with the prior art, the system has the following advantages: the existing resources of a large number of front-end coding devices are fully utilized, and the process of video frame analysis is widely distributed on a large number of nodes of a network, so that the processing pressure on back-end devices is reduced greatly; and the front-end coding devices can also carry out strategic storage on the basis of video analysis, and the storage resources of users are saved greatly.

Description

A kind of vehicle speed detector based on video analysis
Technical field
The present invention relates to intelligent video analysis technical field, more particularly to a kind of vehicle detection system based on video analysis System.
Background technology
Traditional monitoring work is passive type, can not differentiate threat and whether there is, and to lean on supervisor to pass through scene picture Face is defining the generation of accident.This requires that supervisor will ceaselessly stare at screen, because they do not know critical eventss When can occur.And supervisor seldom keeps the state that attention is concentrated to check tens screens, so that when true Alarm occur when, but may the personnel of being monitored ignored.In addition, monitoring personnel will spend greatly when needing to check historical summary The time of amount finds out desired picture in huge data.
Intelligent video analysis system can be such that computer offers an explanation from numerous and complicated video image, recognize target object or judge special Determine whether event occurs.In being applied to security protection video monitoring system, useless in image or interference information can be filtered out, be divided automatically Analysis, the crucial useful information extracted in video source, so that the video camera in traditional monitoring system is not only into the eyes for people, Also intelligent video analysis are made into the brain for people.Intelligent video analysis utilize human resourcess, raise the management level and real for reasonable Now efficiently monitoring is made that huge contribution, however, due to technical immature, existing intelligent video monitoring system is not Fully up to expectations, high rate of false alarm and high rate of failing to report tend not to make monitoring personnel trust them completely.Existing intelligent video analysis System only relies on image information analysis and judges whether particular event or behavior occur, although vision is compared to sense organs such as audition tactiles The quantity of information of acquisition is bigger, but if isolated from the visual information for obtaining, the accuracy meeting to particular event description Have a greatly reduced quality, therefore with significant limitation.Secondly, existing intelligent video analysis system is rather dark or excessively strong Signal and poor signal, tend not to accurately be analyzed.In addition, existing intelligent video analysis system Working mould Formula is single, tends not to realize transmission on demand, stores on demand.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of vehicle detection system based on video analysis System.
The present invention is achieved by the following technical solutions:A kind of vehicle speed detector based on video analysis, its It is characterised by, including video collect module, d GPS locating module, communication module, video pre-analysis module, CPU, deposits Storage module, alarm module, the video collect module is connected with merging with d GPS locating module synchronised with communication module, described Video pre-analysis module receives the video information of communication module transmission, the video information after the central processing unit for processing analysis Memory module is stored in after category filter, the alarm module is connected with CPU.
One of optimal way as the present invention, the memory module is data base.
One of optimal way as the present invention, the video collect module is high definition network head.
One of optimal way as the present invention, the communication module is GPS or optical fiber.
One of optimal way as the present invention, the alarm module is audible-visual annunciator.
One of optimal way as the present invention, the video pre-analysis module includes with central processing unit for processing flow process Following steps:
(1) front end encoding device obtains in an encoding process the visual information and location information of frame of video;
(2) predefined frame of video will be met and will stamp video information label;
(3) frame of video is issued into CPU;
(4) when carrying video information mark carries out step (5);
(5) by video information tag stored data storehouse;
(6) when specified visible elements variable quantity is more than threshold values;
(7) visual information of frame of video is obtained, predetermined applied analysis rule is matched;
(8) the match is successful, and analysis result is stored in into data base as using label.
Present invention advantage compared to existing technology is:The present invention takes full advantage of the existing money of a large amount of front end encoding devices Source, will go in the widely distributed great deal of nodes to network of analysis process to frame of video, very significantly alleviate rear end equipment Processing pressure, and front end encoding device can greatly save with doing diplomatic storage on the basis of video analysis The storage resource of user.
