Problems solved by technology

[0002] Video monitoring is the main subsystem of the regional comprehensive situation monitoring command system. Cameras such as fixed guns and PTZ ball cameras are installed on the monitoring site. The monitoring center adopts a display mode of one camera and one window, and uses two-dimensional maps or three-dimensional maps of the monitoring area. When the model is comprehensively displayed, add an icon to the camera installation position, manually click the icon or select the surrounding area to call up the relevant camera window, because the video image only schematically matches the 3D model, the comprehensive situation in the scene of the city, park, station, etc. In monitoring and command applications, it is difficult to efficiently locate and dispatch massive video and related information, which restricts the technical upgrade and actual combat effectiveness of the comprehensive situational monitoring and command system

Abstract

The invention relates to the technical field of comprehensive situation monitoring and commanding. The invention particularly relates to a video fusion and video linkage method based on a three-dimensional scene and electronic equipment. The method comprises the steps of three-dimensional modeling of a monitoring area, planning and deployment of a scene and a target camera, enhancement, jitter elimination and correction processing of a scene video, recognition and analysis of a scene video, three-dimensional matching and fusion of the scene video and a thermodynamic diagram thereof and a hotspot target, three-dimensional matching and linkage of the target camera, monitoring and correction of pose offset of the scene camera and the like. Accurate space matching and fusion display of a scenecamera video image, a thermodynamic diagram of the scene camera video image, a hotspot target and a scene three-dimensional model are realized; the target camera is intelligently dispatched to obtaina fine image of the hotspot target; accurate space matching and fusion display of other situation awareness information, equipment facility information and task management and control information anda scene three-dimensional model are realized; full-dimensional situation fusion monitoring based on a three-dimensional scene and intelligent space positioning analysis and associated information fusion display based on hotspot inspection, planned tasks and detection alarm are achieved, and the intelligent level and application efficiency of a comprehensive situation monitoring command system areremarkably improved.
