Problems solved by technology

[0003] Most of the existing technologies are based on the video fusion of a single 3D engine. Compared with the video fusion of the 3D geographic information system, it is limited in the scope of application and cannot form a 3D visualization application platform for the whole city, the whole country or a larger scope, and is limited to the application of a single scene. The display is just a splicing scene in a small or large display area on the basis of video fusion, and the information and functions provided are also very scarce.

Abstract

The invention provides a multi-source information fusion visualization method and system. The method comprises the following steps: acquiring sensor data; fusing the sensor data with the three-dimensional geographic information; performing linkage switching on the fused three-dimensional geographic information and the two-dimensional plane map; and carrying out reality simulation and video fusion on the three-dimensional map roaming scene. According to the multi-source information fusion visualization method and system provided by the invention, a function of positioning in a three-dimensional map while video fusion in a large scene is realized on the basis of a three-dimensional geographic information system, a monitoring video can be played to a window, multi-window joint monitoring is realized, a specific small scene can be switched to roam, and fine monitoring is realized; therefore, the video analysis and artificial intelligence application value is improved.

Description

technical field [0001] The invention relates to the field of three-dimensional visualization of geographic information, in particular to a multi-source information fusion visualization method and system. Background technique [0002] At present, the augmented reality system based on video fusion provides a good way for people to quickly and intuitively understand multi-channel video images, and is widely used in video surveillance, virtual simulation of cities, and remote control of robots. However, the current method of merging video and 3D scenes is to simply embed the video into the 3D scene, seldom considering the spatial position and spatial information of the video, and the lack of realism cannot achieve the effect of practical application. At the same time, in the process of video-enhanced 3D scene rendering, when large-scale 3D models and video data are loaded, the display speed of the scene will slow down, which will greatly affect the display efficiency of the scen...
