Multi-view-angle three-dimensional landscape stereo digital holographical sand table system

Abstract

The invention relates to a stereo digital holographical sand table system built on the basis of a three-dimensional landscape of multi-view-angle aeroplane photography. The system comprises a stage, a virtual reality display assembly, a holographical digital intelligent sand table, a playing sever sub system, a projection imaging sub system and an intelligent general control platform, wherein the virtual reality display assembly comprises a first display part, a second display part, a third display part and a fourth display part; the holographical digital intelligent sand table comprises a field photon holographical display map. A projection screen, a 3D (three-dimensional) screen and a holographical screen which are in multilayer arrangement are used; the fusion of different stage display spaces is realized; the effect of integrating real scenes with virtual images is generated; the perfect technical effect is shown; then, the music and the lamp light are combined; the dreamlike effect which cannot be realized by a conventional stage is achieved. The multifunction of a display object can be shown on a single video carrier; the problems that a conventional sand table model needs to be frequently regulated, the display mode is single, and other limitation exists are solved.

Description

technical field [0001] The invention relates to a holographic imaging sand table system in the field of space virtual imaging technology, in particular to a three-dimensional digital holographic panoramic sand table system based on multi-view aerial photography three-dimensional landscape construction. Background technique [0002] The sand table is a model showing terrain and ground targets made with sand or other materials and wargames on a scale based on topographic maps, aerial photos, and on-the-spot terrain. It has the characteristics of strong three-dimensional sense and intuitive image. The sand table has a wide range of uses. It can vividly display the terrain of the combat area, and show the composition of the enemy's and our own positions, the deployment of troops, and the configuration of weapons. The sand table is generally mainly used by commanders to study terrain, enemy situation, combat plan and exercise tactics. With the development of electronic computin...

AI Technical Summary

Problems solved by technology

The production of electronic sand tables is becoming more and more common, but the sand tables produced by the current electronic sand table technology are all the results of 3D simulation technology. When displayed, they are displayed on a flat-screen monitor or projected on a screen, which limits the number of observers. The number of people or autonomy, all observers observe the same information, the perspective of observation can only be controlled by a certain person, or the observation route has been prepared in advance

Therefore, the current electronic sand table cannot completely replace the traditional sand table
