Geographic information guide method and system based on augment reality

Abstract

The invention discloses a geographic information guide method and a system based on augment reality, which mainly solves the problem that the existing map-type geographic information guide method has poor intuition and needs to identify geographic direction. The guide method of the invention is as follows: firstly, collecting a plurality of images from different angles, and determining the projection coordinate of a target space point on a specified initial image plane by geometric calculation; secondly, accurately determining the coordinate of the target space point in a real-time video by geometric calculation on the basis of the projection coordinate of the target space point on the initial image plane and the real-time angle information of a camera; and finally, overlaying virtual geographic information at the position of the target space point in the real-time video, and fusing the virtual geographic information and real scenes in the video through video treatment, thus ensuring the target to be more visual and intuitive and easier to be identified by people. The invention has the advantage that the virtual geographic information provided by the invention is intuitive and effective, and the invention is applicable to places requiring geographic information guide.

Description

technical field [0001] The invention belongs to the technical field of information processing, relates to a geographic information guidance method and system, and can be used in places requiring geographic information guidance. technical background [0002] Augmented reality (AR, Augmented Reality) is a technology that uses virtual objects to enhance the reality of real scenes. It is based on the real physical environment collected by acquisition devices such as cameras. Mark on the objects in the real physical environment displayed on the display screen, so as to realize the annotation and description of the real physical environment in which the user lives. Augmented reality technology gives users an experience of combining virtual objects and real environments, which can effectively help users recognize the surrounding environment and add information about the surrounding environment. [0003] Geographic Information System (GIS) is a system that uses electronic computers...

AI Technical Summary

Problems solved by technology

[0005] 1. The flat map display is not intuitive enough, it is only suitable for people who often look at maps

[0006] 2. It is necessary to identify the geographical direction first when searching through a flat map, but for many people, it is not easy to accurately identify the direction in an unfamiliar place without using other tools or external factors

[0007] 3. There is a lack of expression means for the detailed geographic information guidance of large buildings such as shopping malls, government office buildings, and school teaching buildings
