Geographic information teaching demonstration device and method

Abstract

The invention discloses a geographic information teaching demonstration device and method. The device comprises a teacher end, a cloud server, a geographic information database, an audio and video display system, a 3D printing system, a holographic projection system and student ends, the model data output end of the geographic information database is connected with the 3D printing system, and theimage information output end of the geographic information database is connected with the holographic projection system. Teaching material data uploaded to the cloud server by the teacher terminal isconnected through the geographic information database, and the geographic information is output to the 3D printing system through model conversion to print the geographic information model of the entity, students can actually touch the accurate geographic information sand table, an accurate three-dimensional model can be projected through holographic projection to be displayed in space, and finally, the audio and video information of the geographic information is displayed by combining the two systems with the existing audio and video display system, so that the student terminal can check thestored audio and video data at any time and integrates entity, space and audio and video display, and the learning interest of students is improved.

Description

technical field [0001] The invention relates to the field of geographic information teaching, in particular to a geographic information teaching demonstration device and method. Background technique [0002] Geographical information is the geographical meaning contained and expressed by geographic data. It is the general term for numbers, texts, images and graphics related to the quantity, quality, nature, distribution characteristics, connections and laws of substances related to geographical environment elements. Geographical information belongs to space. Information, the identification of its location is associated with data, which is the most significant sign (spatiality) that distinguishes geographic information from other types of information. Secondly, geographic information has the characteristics of multidimensional structure (multidimensionality). In the prior art, for geographic information teaching, most of the demonstrations can only be performed through audio ...

AI Technical Summary

Problems solved by technology

In the existing technology, most of the demonstrations for geographic information teaching can only be performed through audio and video systems. The demonstrations are not intuitive enough, and students are not interested enough, resulting in poor teaching effects. Therefore, there is room for improvement
