Large-scene multi-target tracking shooting video monitoring system and monitoring method thereof

Abstract

The invention relates to a large-scene multi-target tracking shooting video monitoring system. The large-scene multi-target tracking shooting video monitoring system comprises a large-scene camera shooting sub-system and a target tracking camera shooting sub-system, wherein the large-scene camera shooting sub-system adopts a high-point fixed focus camera used for shooting a video in a large-scene vision field; the target tracking camera shooting sub-system adopts one or more PTZ (Pan / Tilt / Zoom) cameras used for shooting a local video of a moving target in the large-scene vision field in a tracking way; the output end of the large-scene camera shooting sub-system is connected with the input end of the target tracking camera shooting sub-system. The invention further discloses a large-scene multi-target tracking shooting video monitoring method. According to the system and the method, accurate interaction and control between the large-scene camera shooting sub-system and the target tracking camera shooting sub-system are effectively achieved, the corresponding PTZ camera is designated according to a preset priority sequence for movement shooting, a tracked target is located in the imaging center of each PTZ camera all the time, the complexity of the system is reduced, and the image quality and the target tracking reliability of the monitoring system are greatly improved.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a large-scene multi-target tracking and shooting video monitoring system and a monitoring method thereof. Background technique [0002] In the application of video surveillance, in some cases, for example, in public places such as squares and stations, it is necessary to perform video surveillance on objects in a large scene range. Due to the limited angle of view of ordinary fixed-focus cameras, wide-angle cameras are usually used to cover larger scenes. In use, there is a defect that the resolution of the target object is low, it is difficult to see the details of the target object, and the image distortion is very serious. [0003] One of the existing solutions is to use a large number of fixed-focus cameras to cover a large scene, and stitch the pictures taken by these cameras. The disadvantage of this solution is that it needs to increase the number of cameras, wh...

Problems solved by technology

One of the methods is to manually operate the rotation and zoom of the PTZ camera to scan the large scene, but this method is too much work, and it is easy to miss important target information; the other method is in the case of unattended , let the PTZ camera scan the large scene according to the preset trajectory, and turn to the next position after staying at each predetermined position for a certain period of time. In this way, because the PTZ camera can only move along the preset trajectory, some objects Possibility to completely avoid PTZ camera surveillance
