Problems solved by technology

The system cannot automatically capture, track, magnify and collect these targets actively, and cannot obtain the detailed information of the targets
[0006] Although there are also a few intelligent video systems that can intelligently identify and track targets, they can only be carried out on a single area, which is not ideal in terms of monitoring area range, efficiency, or accuracy
At the same time, due to the lack of accurate judgment on suspected targets, additional actions of the system were generated, and there was no secondary verification of true and false targets, resulting in many false alarm messages, which caused monitoring personnel to be lazy in handling system alarm events, and when danger really occurred, delays Processing time, resulting in such security systems not playing their true role, resulting in irreparable losses

Embodiment 1

[0088] A first implementation of an intelligent visual perception system:

[0089] The intelligent visual perception system includes a variable focal length camera and a false target feedback feature information library in the designated monitoring area. Firstly, the false target feedback feature information library of a specific monitoring area is established, including the position information of the false target and the description information of the false target feature. A video image acquisition is performed on the monitoring area with a first resolution. Specifically, such as figure 1 As shown in , the system adjusts the direction and focal length of the camera's field of view, and sets the PTZ parameters so that the video image covers the preset monitoring area that needs to be monitored. The large field of view and small resolution perform video image acquisition on the designated monitoring area. Using a target detection algorithm, the video image collected by the c...

Embodiment 2

[0100] On the basis of the above embodiments, a second implementation of the intelligent visual perception system is also provided:

[0101] Establish a false target feedback feature information library for a specific monitoring area, including false target position information and false target feature description information. Such as figure 1As shown, the system adjusts the direction of the camera's field of view. By setting the PTZ parameters, the video image covers the area to be monitored, and the video image is collected for the first preset monitoring area with the large field of view and small resolution. A target detection algorithm is used for the video images collected by the camera to perform a target detection in the first preset monitoring area. A target detection combines the information of the false target feedback feature library. If the image features of a certain area have a high degree of matching with the false target feedback feature description of the ar...

Embodiment 3

[0121] On the basis of the above embodiments, a third implementation of the intelligent visual perception system is also provided:

[0122] An intelligent visual perception system includes one or more intelligent visual perception devices. A structure of the intelligent visual perception device is composed of a visible light camera, a transmission mechanism, a data processing unit, a communication interface unit, a power management unit, and a protective shell. There is a window and a power supply and signal line interface in the shell, and the window is sealed with a light-transmitting material, which is used for video image acquisition by the camera. The transmission mechanism adjusts the horizontal and vertical field of view positions of the camera through the control commands sent by the data processing unit, including driving motors, horizontal rotating shafts, vertical rotating shafts, control lines, etc. The driving motor drives the camera to rotate horizontally 0-360 ...

Abstract

The invention provides an intelligent visual perception system, which includes a variable focal length camera and a false target feedback feature information library in a designated monitoring area; the camera collects video images of the monitoring area with the first resolution, and adopts a target detection algorithm , performing a target detection in the area, including: judging whether the designated monitoring area contains a suspected target based on the false target feedback feature information library; Carry out video image acquisition, and use the secondary target detection algorithm to perform secondary target detection to determine whether the suspected target is a real target or a false target; when the suspected target is a false target, update the false target feedback feature information according to the information of the false target library; when the suspected target is a real target, track and monitor the real target. The intelligent visual perception system improves the precision and accuracy of the system in capturing environmental anomalies.

Description

technical field [0001] The invention relates to the security field, in particular to an intelligent visual perception system. Background technique [0002] Common movable cameras include PTZ cameras, PTZ cameras, etc., which usually have three control parameters: horizontal rotation, vertical rotation and focal length change. By adjusting these parameters, the movable camera can not only change the focal length to obtain different resolution information of the target or area in the shooting scene, but also change the angle to obtain different field of view information of the target or area in the shooting scene. However, these cameras, when shooting scenes in different areas, control the direction of the camera's field of view through the pan / tilt, and the direction of the field of view is pre-set. This method only realizes an automatic monitoring. [0003] A multi-camera is a commonly used imaging device. The body of the multi-camera is equipped with multiple lenses, and t...
