An interactive digital globe and its interactive method

Abstract

The invention discloses an interactive digital globe and an interactive method. The digital globe includes: a player, a high-definition projector, a fisheye lens, a spherical screen and a motion capture tracker; the output end of the player is connected to the input end of the high-definition projector, and the player is used to play the world topographic map plan; the high-definition projector Located behind the spherical screen, a fisheye lens is fixed in front of the projection lens of the high-definition projector. The high-definition projector is used to project the world topographic map onto the spherical screen through the fisheye lens; the spherical screen is a quarter-spherical screen; the action The output end of the capture tracker is connected to the input end of the player. The motion capture tracker is used to capture the user's arm movement, and the player is also used to adjust the playback effect of the world topography map according to the user's arm movement. By adopting the digital globe of the invention, the cost is greatly reduced, the usability and universality are stronger, and it is beneficial to popularization and application.

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...
