Interactive digital globe and interactive method

Abstract

The invention discloses an interactive digital globe and an interactive method. The digital globe comprises a player, a high-definition projector, a fisheye lens, a spherical screen and an action capture tracker; the output end of the player is connected with the input end of the high-definition projector; the player is used for playing world topography and plane graphs; the high-definition projector is located behind the spherical screen; the fisheye lens is fixed to the front part of a projection lens of the high-definition projector; the high-definition projector is used for projecting theworld topography and plane graphs to the spherical screen through the fisheye lens; the spherical screen is a screen of a 1 / 4 spherical surface; the output end of the action capture tracker is connected with the input end of the player; the action capture tracker is used for capturing arm actions of a user; and the player is further used for adjusting the playing effect of the world topography andplane graphs according to the arm actions of the user. By adopting the digital globe, the cost is greatly reduced, the availability and universality are higher, and the popularization and applicationare facilitated.

Description

technical field [0001] The invention relates to the field of digital globes, in particular to an interactive digital globe and an interactive method. Background technique [0002] At present, research on electronic globes at home and abroad is mainly focused on holographic analog globes made using holographic projection technology, such as Orboot globes, geography popularization simulation demonstration globes, and 180-degree holographic interactive electronic globes. [0003] (1) Orboot Globe is a virtual globe developed using AR augmented reality technology, which has three major features: 3D stereoscopic animation, real voice, and AR interaction. The globe is based on iOS or Android devices, and depicts a three-dimensional earth through AR programs. At present, the product is mainly used for popular science teaching. [0004] (2) Geography popularization simulation demonstration globe, mainly has two products, one is a large suspended globe, which uses electromagnetic r...
