Prewarning positioning monitoring device of multi-directional monitoring area

Abstract

The invention provides a prewarning positioning monitoring device of a multi-directional monitoring area, which can monitor a panorama region with a larger monitoring range under the condition of low illumination level. The prewarning positioning monitoring device comprises a vertical prewarning mechanism, a horizontal prewarning mechanism and a warning part. The monitoring device directly detects trends in a plurality of prewarning video images through acquiring prewarning videos in multiple directions, thereby determining position information of a movement object to be monitored, marking an outline and a movement curve of the movement target in a monitoring area, and carrying out illumination warning and sound warning on the movement target; meanwhile, warning signals are added in the corresponding video images, retransmitted commands control a main control device to generate a warning action, and a plurality of prewarning videos marked with the outlines and the movement curves of the movement target are stored and transmitted to a display device of a video monitoring system. The monitoring device has a function of regulating the multi-direction monitoring area and is remarkably improved in applicability and flexibility.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, and in particular relates to a multi-directional monitoring area early warning and positioning monitoring device. Background technique [0002] 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. [0003] At present...

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 collect wide-area video in the monitoring area, and use, for example, a PTZ camera to collect local centralized video in a certain monitoring area in the wide-area video. The above-mentioned video surveillance front-end equipment is often used to track and monitor moving targets, but the 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

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