A geographical information interaction method, system and storage medium based on VR technology

Abstract

The invention relates to a geographical information interaction method, system and storage medium based on VR technology. The geographic information interaction method includes: establishing a three-dimensional geographic model in a VR scene; acquiring the position and attitude of the VR device; and determining a marked area aligned with an alignment line of the VR device according to the position and attitude; judging whether the marked area corresponds to a virtual slice The preset area; if so, when the VR device controls the movement of the virtual slice, the virtual slice is used to obtain the 3D image slice in the 3D geographic model. In the embodiment of the present invention, by acquiring the position and posture of the VR device in the three-dimensional scene, the region aligned by the alignment line of the VR device is determined, and when the region aligned by the alignment line is the region corresponding to the virtual slice, the Virtual slicing obtains 3D image slices in the 3D geographic model, and obtains local slices in the 3D geographic model in real time through interactive means, which is convenient for users to observe and process the details of the 3D geographic model.

Description

technical field [0001] The present invention relates to the technical field of VR display, and in particular, to a method, system and storage medium of geographic information interaction based on VR technology. Background technique [0002] A geographic model refers to a physical model or a mathematical statistical model that abstractly represents the state of a regional geographic system or the characteristics of its constituent elements. It is one of the important tools and methods of geographic scientific research. However, due to the complexity, variability and openness of the regional geographic system, many factors affecting the regional geographic system and their functions cannot be accurately determined. And geographic models are relatively rare. Geospatial models established using maps and remote sensing techniques are unique tools for geographic research. [0003] On the computer side, some 3D software can process the visualized terrain data, such as taking the...

[0004] However, the various images or processed data information displayed on the computer side are all flat display diagrams, and users need to constantly adjust the images displayed in the 3D software to construct corresponding 3D scenes in their minds. The displayed scene may have areas that cannot be displayed, and users cannot effectively obtain global image changes
