Electronic sand table system and method

Abstract

The invention relates to a sand table, in particular to an electronic sand table and method. An electronic sand table system is strong in stereoscopic impression, visual in image, capable of simulating various landforms and urban environments vividly. The electronic sand table system comprises a scene establishment module (1), a calculation module (2), a control module (3) and a demonstration module (4). The demonstration module (4) comprises a display matrix (401) composed of a plurality of columnar display units (4011). The top plane and each side face of each columnar display unit (4011) are display screens. Through ascending and descending of the columnar display units, simulation of the landforms and simulation the shapes of ground objects are achieved. Through the display screens of the columnar display units (4011), colors and textures of the landforms and the ground objects are simulated. The electronic sand table system is realistic in effect, strong in stereoscopic impression, capable of simultaneously describing the shape and the texture of each three-dimension scene in detail, flexible in operation, capable of enabling a sand table design scheme to be adjusted dynamically and achieving real-time and synchronous display, convenient to update, and good in expandability.

Description

technical field [0001] The invention relates to a sand table, in particular to an electronic sand table with a strong sense of three-dimensionality, an intuitive image, and the ability to realistically simulate various terrains and urban environments and a method thereof. Background technique [0002] The sand table is a model made of sand, war chess and other materials according to a certain proportion relationship based on topographic maps, aerial photos and topographic information. Traditional sand tables are usually used in the military field, and are mainly used by commanders to study terrain and combat plans and practice tactics. But in recent years, more and more fields, such as urban planning, geological exploration, real estate display, emergency command, scenario deduction, etc., have begun to use sand tables. In particular, the emergence of the electronic sand table has broadened the scope of application of the sand table. The traditional sand table has a strong...
