Abstract

The invention discloses an IMU-GPS assisted 360-degree panoramic photo and three-dimensional GIS scene linkage method. The method comprises the following steps: S100, estimating the position and attitude of a panoramic camera at the shooting moment through an IMU/GPS assisted 360-degree panoramic photo; S200, positioning the three-dimensional space position of the panoramic camera in a geographic coordinate system where the three-dimensional GIS scene is located; S300, matching a viewpoint of the three-dimensional GIS scene with a point location and a posture of the panorama camera; and S400, realizing real-time linkage of the photo and the three-dimensional GIS scene through a presentation platform. According to the method, the defects in the prior art can be made up, the defect that a traditional panoramic photo is linked with a two-dimensional scene only depending on the position is overcome, the vacancy of linkage of the panoramic photo and a three-dimensional GIS scene is filled up, space information is enriched, and a basis is provided for expanding a three-dimensional scene presentation mode and improving the position-based service level.

Description

technical field [0001] This application relates to the field of spatial information technology, and specifically provides an IMU-GPS-assisted linkage method of 360° panorama photos and 3D GIS scenes and a presentation platform thereof. Background technique [0002] The 3D GIS scene adopts the virtual reproduction of the real scene composed of 3D models of terrain, images, and surface coverings, which can show the real world from a 3D perspective; at the same time, the 3D GIS scene presentation platform has full-dimensional browsing, roaming, Functions such as zooming and zooming provide a rich interactive experience, and the storage of geographic information data is also diversified. The full name of IMU is Inertial Measurement Unit, that is, inertial measurement unit, which is a sensor mainly used to detect and measure acceleration and rotational motion. 360° panorama photos have relatively rich textures and panoramic perspectives, and have the potential for immersive expe...
