What is intelligent analysis
Refers to the computer image visual analysis technology, which analyzes and tracks the objects that appear in the camera scene by separating the background and the objects in the scene. According to the video content analysis function, the user can preset different alarm rules in different camera scenes. Once the target has violated the predefined rules in the scene, the system will automatically send an alarm, and the monitoring workstation will automatically pop up alarm information. A warning tone is issued, and the user can click on the alarm information to realize the scene reorganization of the alarm and take related measures.
What is automatic tracking
When the moving target enters the camera's field of view, a high-speed DSP chip is used to perform differential calculations on the previous frame of the image and the current image. When a certain value is reached, a particular part of a frame is determined as a moving object, and then The ball machine automatically issues instructions to the ball head, so that it cycles back and forth, thus controlling the ball camera to achieve continuous tracking of moving objects without human operation, and does not require the support of computer systems!
What is a video surveillance device?
On the same structure, there is a parent ball and N sub-guns (selected according to the application scenario).
Foreword
The current intelligent video surveillance system has been able to automatically lock and effectively track the detection target. This type of intelligent monitoring system greatly reduces the number of monitoring personnel, greatly improving work efficiency and tracking performance. Automatic tracking is to perform differential calculation on the basis of intelligent recognition, automatically recognize the direction of target movement in the visual range, and automatically control the PTZ to track the moving target, and at the same time, it can cooperate with high-definition automatic zoom lens when the target is entering the intelligence. All video is transmitted to the monitoring center within the sight of the dome camera until the time of departure. Once an alarm occurs in a certain area of ​​the system, the related fastball will automatically rotate to the alarm point to start tracking, and it can be set to start the video or capture and start the surrounding lights, alarm bells and other linkage functions. However, there are some problems that cannot be solved by the single camera tracking system, such as the occlusion problem of the target of monitoring the scene, the limitation of the visual field of the camera, and the incapability of three-dimensional tracking of the target.

On the same structure, there is a cue ball and N sub-guns (according to the application scenario). The ball and the gun are linked by an intelligent algorithm. The monitoring range (especially the feature discriminating area) of the bolting machine is expanded, and the ball machine is also expanded. Solve the problem of missed shots during rotation. The intelligent gun body has the same body, high reliability and simple installation. Both material cost and engineering cost can be saved. The intelligent sub-matrix has a special design that integrates and creates a new surveillance camera shape. According to different application scenarios, the contractor can choose different models, such as 1+2 for ordinary streets, 1+3 for T-junctions, and 1+4 for crossroads or squares. The machine is not a mechanical combination of a bolt and a ball machine, but an intelligent combination. It can be seen that the original design of the intelligent mode is not to achieve automatic tracking, but to solve the defects of traditional cameras and combine their advantages. For the "Safe City Construction" to provide quality products.
principle
In the intelligent model, the “spinner†part completes the monitoring of the fixed angle. The “cue ball†can simultaneously acquire the video data of the bolt machine for intelligent analysis, automatically adjust the angle and focal length, lock the target image, and track the target.
A number of intelligent analysis scene algorithms have been embedded in the unit's factory. For example, "remnant detection" can be used for illegal parking monitoring of vehicles. When the "sub-gun" detects roadside parking for more than a certain period of time, it sends instructions to the "parent ball." , "Cue" to adjust the appropriate angle and focal length, you can identify the license plate of the illegal vehicle; "Abnormal run detection" can be used for a variety of security incident monitoring, such as snatching the incident, when the "sub-gun" detected square or road The person who runs fast, that is, sends instructions to the "cue ball", and the "parent ball" adjusts the proper angle and focal length to recognize the facial features of the running person and make automatic tracking as the running person's movement is constantly adjusted. In the traditional monitoring of bolts and bolts, the range of “feature recognition areas†that can characterize people’s vehicles is very limited, and it is often seen that there are cases but it is impossible to know the license plate number in the case and the facial features of the suspect. The machine has greatly improved the practicality of the "Safe City" system. The machine adopts panoramic technology, intelligently splicing several “sub-guns†images, and can output single-channel images and panoramic mosaic images. At the same time, the details captured by the dome can be displayed through “picture-in-pictureâ€. . Because of the gun and ball, using the same structure, the same main board, the same network module, the same power supply module, and only one network interface, only one pole is needed during installation, and the cost is greatly reduced.
Although the intelligent mother-in-one camera is not a purely tracked surveillance camera, it offers a new perspective for tracking cameras.
in conclusion
The cross-camera tracking system is a comprehensive monitoring of the target. The monitoring line is long, and its feature recognition area is wide. Because of the combination of multiple cameras, its structure is flexible, and different structures can be adopted according to specific conditions. However, its outstanding problem is that it is prone to missed shots and it is costly. The intelligent master unit solves the problem of missed shots of the dome camera and gives full play to the respective advantages of the dome camera and the bolt camera. The installation is simple, the reliability is high, and the cost is lower.
