Video monitoring in the future the Intelligent analysis of the application of

Intelligent video analysis system is the monitoring of the development direction, this technology is far away from us, the Qinghai-Tibet railway line 1300 channels using video analysis, conducted on line railway; just intrusion protection opened subway line 5, with a focus on regional use of bombed detection and intrusion detection; Beijing aeronautical information centre of the engine room, the use of intrusion detection and guards; Metro line 13, the use of video analysis caught stealing thieves; Pudong airport, airport and has more than one under construction projects, budget using video analysis technology ...

Intelligent video system to resolve the problem, there are two: one is the security operations personnel from tedious and boring "on screen" task, the machine to complete this part of the work; the other is in a flood of video data in the quick search to find the image.

The operations staff at screen television display more than 10 minutes will miss a 90 per cent of video information and make this work in meaningless; London underground, the security staff spent 70 hours before in a large number of tape to find the information you need. As a result of the above two points, you must select a video analysis system, video analysis system will in future become standard with the monitoring system.

Video analysis of the background is very simple, that is, when the person on duty in the face of ten, a hundred, a thousand cameras, not real in risk prevention or intervention arise, most rely on subsequent playback related image; the second is a non-security applications, such as commercial traffic statistics, to prevent theft and so on.

The risk analysis and recognition to the computer or chip, so that the person on duty at the "dead" monitor out of work when the computer finds a problem, generate alerts, and the person on duty to respond.

The main advantage of intelligent video monitoring:

• Fast reaction time-millisecond response time of the alarm trigger

• More effective monitoring – security operator only needs to pay attention to relevant information

• Powerful data retrieval and analysis capabilities, can provide a fast response time and investigate time

1. incident detection and behavior analysis: video with perimeter monitoring and exception behavior analysis, used for testing, classification, track, and record past pedestrian, vehicle and other suspicious object, to determine whether there are pedestrians and vehicles in a closed area occurred a long time wandering, stay, retrograde, behavior detection officers, in addition to run, such as unusual behavior in the fight.

2, advanced video motion detection: the weather in complex environments (such as rain, snow, fog, wind, etc.) accurate detection and identification of a single object or multiple objects of the movement, including the movement direction, movement, etc.

3, object tracking: detect moving objects, depending on the movement of objects, automatically send PTZ control directive, so that the camera can automatically track the objects in the object is out of range of the camera monitoring, automatic notification objects in the region of the camera to continue tracking.

4, illegal detention: when an object (such as a box, parcel, vehicle, person, etc.) in sensitive areas stay for too long, or more than predefined time length produces alarm.

Typical application scenarios including the airport, railway station, subway station, etc.

5. number of statistics: statistics through the portal or the specified range of the number of persons or objects.

For example, calculating a day for owners to patronize their shops in the number of customers.

6, crowd control: identify the overall movement of people, including speed, direction, and so on, to avoid congestion, or timely detection of abnormalities.

Typical scenarios include supermarkets, railway staff gathering place.

7. traffic flow control: for the highway or link monitor traffic conditions on the highway, such as statistics by car, average speed, whether it is illegal to dock, faulty vehicle and so on.

8, lens protection: for fixed camera monitoring sites, such as the camera is blocking, the camera is moved, the camera appears fuzzy, in similar cases promptly notify maintainers.
