Multidirectional early-warning positioning and automatic tracking and monitoring device for monitoring area

Abstract

The invention relates to a multidirectional early-warning positioning and automatic tracking and monitoring device for a monitoring area, which still can monitor a panorama area with a large range even under the condition of low illumination. The monitoring device comprises an early-warning positioning mechanism and a tracking warning mechanism, wherein an early-warning positioning module is arranged inside the early-warning positioning mechanism, and a tracking warning module is arranged inside the tracking warning mechanism. According to the monitoring device, a plurality of directions are subjected to early-warning video collection so as to directly detect the trends of the inside of a plurality of early-warning video images to determine the position information of a monitored moving object, and therefore, the moving object is subjected to tracking video collection, voice frequency collection, illumination warning and sound warning. Meanwhile, an alarm signal is added in a corresponding video image, master control equipment is controlled by passing an instruction back to generate an alarm action, and finally, a plurality of early-warning videos and tracking videos are stored and transmitted to display equipment. The monitoring device has a multidirectional monitoring area regulation function, and the applicability and the flexibility of the monitoring device are obviously improved.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a multi-directional monitoring area early warning positioning automatic tracking monitoring device. Background technique [0002] At present, in the field of video surveillance technology, the existing video surveillance system usually includes video surveillance front-end equipment, transmission equipment, main control equipment, display equipment and other equipment. Among them, the video monitoring front-end equipment is mainly responsible for the collection and processing of data and video signals; the transmission equipment transmits the above-mentioned collected data and video signals to the main control equipment and display equipment; The unit issues control instructions, which are transmitted by the transmission equipment to the video surveillance front-end equipment, and the display equipment processes the video signal and displays it on the display unit.

AI Technical Summary

Problems solved by technology

[0004] The first type is a fixed-point video acquisition device, that is, a fixed-point camera is used as a video surveillance front-end device to monitor a designated area. This type of video surveillance front-end device can only monitor a fixed direction, and there are monitoring blind spots

[0005] The second type is a rotating video acquisition device, which uses a device that can rotate in the horizontal and vertical directions to drive the camera for multi-directional monitoring, such as the combination of a pan-tilt device and a camera (hereinafter referred to as "pan-tilt camera") as a video surveillance front end Although this type of video surveillance front-end equipment solves the problem that the monitoring direction cannot be adjusted, it cannot monitor multiple directions at the same time, so there are still monitoring blind spots

[0006] The third category is to adopt the fixed-point video acquisition device to cooperate with the rotating video acquisition device, such as the intelligent monitoring device proposed by the patent application publication number CN102342099A and the image monitoring system using the device, which mainly adopts such as wide-angle camera (wide-angle lens and analog camera / digital camera) Combination) to carry out wide-area video collection on the monitoring area, and use such as PTZ camera to carry out partial centralized video collection on a certain monitoring area in the wide-area video. The video image collected by the monitoring device by installing a wide-angle camera such as a fisheye lens is distorted and distorted, making it difficult to identify moving targets at the edge of the video image, thus limiting the monitoring range

[0007] And because the wide-area video acquisition equipment of the above-mentioned monitoring device is fixed and cannot be adjusted, the monitoring area of ​​the wide-area video acquisition cannot be changed in direction, which affects the adaptability and flexibility of the above-mentioned monitoring device

[0008] At the same time, because the above-mentioned monitoring device does not use auxiliary lighting equipment, it cannot locate and track moving targets in the monitoring area at night or under low-light conditions.

[0009] In addition, none of the above three types of video surveillance front-end equipment can warn moving targets
