Method and apparatus for associating actual object information in video monitoring image

Abstract

The invention discloses a method and apparatus for associating actual object information in a video monitoring image. According to a monitoring scene of a video monitoring unit, a three-dimensional model is established; and a virtual camera with information consistent with position information and parameter information of an actual camera is set in the three-dimensional model. The method comprises: receiving a position coordinate inputted into a video monitoring actual image; according to the established three-dimensional model and virtual camera, obtaining a virtual object corresponding to the position coordinate in the three-dimensional model; and searching object information corresponding to the virtual object and superposing the information on the actual image for displaying. In addition, the apparatus consists of a three-dimensional model establishment module, a receiving module, a matching module and an information superposition module. According to the invention, with three-dimensional model establishment, association of the target object and the actual objet information in the video monitoring image is realized, so that the user can obtain object information at an actual situation monitoring picture.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, and in particular relates to a method and a device for associating real object information in video monitoring images. Background technique [0002] With the application of 3D technology in the field of video surveillance, many functions have new solutions, which may be more intuitive and convenient than traditional implementation methods. Traditional video playback is difficult to intuitively reflect the state information of real objects, and the connection between the information that can be conveyed on the image and the real objects is poor. For example, a building seen in an outdoor image cannot be directly associated with the detailed information of the building, and the equipment in the computer room in the indoor image cannot be associated with the name and status of the equipment, such as whether it is faulty or not. [0003] In the prior art, the relationship between the target...

Problems solved by technology

However, in this way, it is impossible to directly view the real object information corresponding to the target object in the existing video surveillance, and it needs to be operated and viewed in the 3D simulation software. connection, it is inconvenient to check directly
