Reservoir area three-dimensional real scene display method based on WEBGIS

Abstract

The present invention discloses a reservoir area three-dimensional real scene display method based on the WEBGIS. The method comprises the following steps: (1) employing an unmanned aerial vehicle toperform aerial shooting of a reservoir area; (2) performing panorama image combination; (3) performing association in pairs of scenes, and calculating position information of an associated scene of each scene through the GIS algorithm; (4) performing three-dimensional real scene generation; (5) extracting longitudes and latitudes of each scene, and loading the longitudes and latitudes on the WEBGIS in a PointMarker mode; and (6) displaying real-time information of reservoir monitoring parameters in the three-dimensional real scene. The reservoir area three-dimensional real scene display methodbased on the WEBGIS realizes scene association automation and employs a WEBGIS electronic sand table to provide a navigation function for the three-dimensional real scene.

Description

technical field [0001] The invention relates to the technical field of three-dimensional real scene display of a reservoir area, in particular to a method for displaying a three-dimensional real scene of a reservoir area based on WEBGIS. Background technique [0002] The existing electronic sand table for 3D real scene applications in the reservoir area uses a fixed-scale background image as the base image. All scene points need to be manually plotted on the background image one by one, and set by each scene The angle value of the relevant perspective is displayed to match the camera field of view inside the scene. This kind of electronic sand table cannot realize the real-time and automatic update of the base map and scene points, and it cannot achieve infinite scaling and drag navigation functions like GIS when sand table navigation for large reservoir areas. The connection needs to set information such as the horizontal azimuth and elevation angle of the associated scene...

Problems solved by technology

This kind of electronic sand table cannot realize the real-time and automatic update of the base map and scene points, and it cannot achieve infinite scaling and drag navigation functions like GIS when sand table navigation for large reservoir areas. The connection needs to set information such as the horizontal azimuth and elevation angle of the associated scene in the current scene in each scene. All hotspots in the existing reservoir panorama application can only be set with static information such as the construction of the reservoir, which cannot provide The association of dynamic information makes it impossible to intuitively integrate many dynamic data such as reservoir water level, storage capacity, and machine owner operation into panoramic applications. To view these dynamic information, it needs to be performed in another system application.
