Problems solved by technology

[0005] 1. The traditional sub-camera monitoring mode has the application limitations of isolated screens and lack of correlation, and it is difficult to intuitively obtain the overall security situation of the monitoring area
[0006] 2. At present, the combination of surveillance video and 3D scenes is limited to extracting key video frames and displaying them in the 3D scene in the form of annotations. This method is difficult to display video in real time and intuitively. The viewing operation of monitoring areas and monitoring targets is complicated and not intuitive.

Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] The 3D panoramic fusion video surveillance system includes four modules: server module, video processing module, 3D scene module, and fusion processing module.

[0039] The detailed technical plan can be summarized into the following four modules:

[0040] 1. Server module: the front-end video acquisition equipment is a variety of different types of surveillance cameras distributed in different geographical locations. The surveillance video is transmitted back to the server in the network center through optical fiber. The server physically stores the videos of each channel and establishes the ID of the surveillance camera. The mapping relationship between its video stream on the server path, the GPS position of the camera, roll angle, tilt angle, yaw angle, etc., and store it in the database.

[0041] 2. Video processing modul...

Abstract

The invention provides a monitoring video fusion system and a monitoring video fusion method based on a three-dimension space scene. Video frames are extracted from a monitoring video data stream and are projected to a three-dimension space scene so as to realize full-space-time stereo fusion of video data and three-dimension scene data and change a traditional mode in which a map application can only be statically displayed; and a plurality of channels of real-time monitoring videos deployed in different geographic locations and a three-dimension model in a monitoring area are registered and fused so as to generate a large-range three-dimension panoramic dynamic monitoring picture and realize real-time global control on the overall security situation of the monitoring area.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a system and method for monitoring video fusion based on three-dimensional space scenes. Background technique [0002] With the wide application of GIS technology, video system solutions integrating spatial location information such as two-dimensional maps are gradually becoming mature. Compared with the traditional video surveillance system that simply acquires real-time audio and video information of monitoring targets, the 3D video surveillance system that inherits 3D spatial information will play a greater role in enhancing users' spatial awareness and assisting users in emergency decision-making. [0003] In terms of 3D video surveillance, it is currently common practice to collect pictures from real-time images from various places and display them in the 3D scene in the form of annotations. When the user wants to know the surveillance image of a certain place, click on the...
