Mixed reality electronic sand table system and simulation method

Abstract

The invention discloses a mixed reality electronic sand table system and a simulation method. The system comprises a display device (1), a sand table console (2), a main control computer (3), a head-mounted display (4), an operation handle (5), a camera switch (6), and a camera module (7). The display device is embedded into a sand table top, and the sand table content is displayed by the display device. The sand table content can be directly operated by touch, supplemented by detailed description and explanation. A pair of head-mounted mixed reality glasses is used as a virtual scene observation device to carry out simulated marching in a local virtual scene, wherein the operation is performed by gestures. Global planning can be carried out based on a global view, and local visibility test can be carried out. Moreover, marching can be simulated. The system is of higher practicability in route planning and time checking.

Description

technical field [0001] The invention relates to the field of sand table applications, in particular to a mixed reality electronic sand table system and a simulation method. Background technique [0002] Patent Document 1: An electronic sand table includes a sand table transparent glass cover, a lower casing, a base, a three-dimensional imaging display screen and a large LED lamp. The top of the lower casing is provided with a glass cover bracket, and the sand table transparent glass cover is installed on the On the glass cover support, a large LED lamp holder is arranged inside the glass cover support, the three-dimensional imaging display screen is installed above the lower casing, the large LED lamp is installed on the large LED lamp holder, and the small A small LED lamp is arranged on the LED lamp socket, and the base is installed on the bottom of the lower casing. The interaction between the imaging display screen and the transparent glass cover of the sand table reali...

Problems solved by technology

[0004] The disadvantage of Patent Document 1 is that due to the limitations of the imaging principle and system structure design, the objects in the sand table cannot be well controlled in real time, and only a global overview is not possible, and there are also great shortcomings in experience. Visual judgment has great disadvantages. Real-time tour of the route and calculation of travel time can only rely on imagination and experience, which has obvious disadvantages in the practicality of the sand table system
