Method and device for video surveillance

Abstract

The invention discloses a method and device for video monitoring. A monitoring area is divided into a plurality of areas, and each area is provided with sole image collecting point identification. The method includes the steps that a monitoring server obtains images collected by all image collecting devices and identifies image collecting point identification contained in all the images; according to the image collecting point identification contained in all the images and the image collecting point identification arranged in all the areas, the monitoring server judges whether a blind zone not covered by the image collecting devices exists or not; if yes, adjusting parameters of the image collecting devices are determined, therefore the blind zone is covered by the image collecting devices, and the image collecting devices are indicated to perform adjustment according to the adjusting parameters. The problem that the monitoring blind zone appears in the video monitoring process is solved, the monitoring server is used for automatically judging the monitoring blind zone and adjusting the image collecting devices intelligently, so that the monitoring blind zone is cleared in real time, and safety performance of a video monitoring system is improved.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a video monitoring method and equipment. Background technique

[0002] At present, the most common monitoring front-end equipment in the video surveillance market is composed of image acquisition equipment (such as cameras) and PTZ equipment. The administrator of the video surveillance system controls the monitoring posture of the camera by remotely sending the PTZ control command, captures the required monitoring images, and conducts real-time monitoring. In the monitoring scene, public areas, such as traffic arteries, squares, public places, etc., are often equipped with multiple image acquisition devices to achieve all-round and multi-angle monitoring effects. Such as figure 1 As shown, three image acquisition devices are set in the monitoring area, and each image acquisition device is arranged at a preset point, and their respective monitoring ranges complement each ...
