Building display sand table for teaching

Abstract

The invention discloses a building display sand table for teaching. A plurality of 3D projectors are disposed above the sand table body, and air screen generation systems are placed to be opposite tothe 3D projectors. The air screen generation systems are divided into two groups, wherein one group of air screen generation systems are disposed at two sides of the interior of the sand table body, and the other group of air screen generation systems are disposed at two sides of the exterior of the sand table body. The periphery of the sand table body is provided with a plurality of sound devices, and the interior is provided with a lighting interaction system. The 3D projectors, the sound devices, the lighting interaction system and the air screen generation systems are all connected with amain unit in a machine room. The main unit is connected with a wireless terminal controller through a wireless signal. The external surface of the sand table body is provided with infrared multipointtouch recognition devices in a circle, and the infrared multipoint touch recognition devices are connected with the main unit. The sand table can truly simulate a full-3D and vivid urban environment to build an urban planning model and a building model, also can achieve the man-machine interaction, changes the passive learning into semi-active learning and greatly improves the learning interest ofstudents.

Description

technical field [0001] The invention relates to the field of teaching aids, in particular to a building display sand table for teaching. Background technique [0002] The 3D digital city can not only accurately express the urban spatial form, layout, color, skyline and other information through virtual reality technology, but also provide users with rich and accurate urban spatial attributes, geographic surveying and planning and other information through 3D geographic information technology resource. And use its powerful spatial data organization, management and spatial analysis capabilities to provide users with technical means such as information query, spatial analysis, information statistics, and information mining. Therefore, there are many cases of using 3D digital city technology to assist planning management and urban construction at home and abroad, and digital sand tables are generally used to realize it. However, there are still some defects in the traditional ...
