Fusion method and system of mobile video and geographic scene and electronic equipment

Abstract

The invention provides a fusion method and system of a mobile video and a geographic scene and electronic equipment. The fusion method comprises the following steps: selecting a video key frame from terrain image data determined according to position information of an unmanned aerial vehicle camera; extracting a matching point of the video key frame and the terrain image; calculating pixel coordinates of video key frame corner points according to the matching point coordinates and a perspective transformation formula, and converting the pixel coordinates into latitude and longitude coordinates; and obtaining a three-dimensional scene model of the mobile video fused to the terrain image by utilizing an interpolation method according to longitude and latitude coordinates corresponding to theangular points of the video key frame. According to the method, the unmanned aerial vehicle video and the geographic scene image are used as the original data, the high-precision matching point of the key frame and the geographic image is obtained according to the ASIFT algorithm, fusion of the dynamic scene of the dynamic scene model of the corresponding video area obtained based on the unmannedaerial vehicle video is achieved through the matching point, and high precision and practicability are achieved.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a method, system and electronic equipment for fusing mobile video and geographical scenes. Background technique [0002] With the continuous development of video technology, there are more and more applications in different fields, such as emergency disasters, etc. When natural disasters such as earthquakes, landslides, and mudslides occur, drones have low cost, strong mobility, and safety. The advantages of small risk factor are widely used in terrain surveying and mapping, oblique photography, scene detection and other fields. However, the current conventional monitoring system, due to the problems of mass video dispersion, isolation, incomplete perspective, and unclear location, especially the integration of mobile video and geographical scenes, security-oriented video monitoring, and emergency disaster reduction, is the solution to this current situation. derived fro...
