Laser holographic projection sand table making device

Abstract

The invention relates to a laser holographic projection sand table making device, and belongs to the technical field of sand table making. The problems that a making cycle of a sand table is long, a display lacks of authenticity and real-time adjustment cannot be carried out in the prior art are solved. The laser holographic projection sand table making device comprises a control terminal, a laserholographic projector, a binocular camera, a laser ranging inductor and an aligning tool, wherein the control terminal is used for establishing a laser holographic projection prediction model, and training is carried out, and projection parameters of the laser holographic projector are obtained in real time through the trained model; the laser holographic projector carries out sand table projection imaging according to the projection parameters; the binocular camera and the laser ranging inductor are used for collecting data required by the training of the prediction model; and the aligning tool is used for position aligning. According to the laser holographic projection sand table making device, the problems of the instantaneity and the authenticity of a traditional sand table can be effectively solved through machine learning and the laser holographic projection; the laser holographic projection can authentically show the state of a simulated landform, when the change of the external environment is monitored, the optimal projection parameters can be obtained in real time, the state of projection can be automatically corrected, and an optimal projection size and effect are achieved.

Description

technical field [0001] The invention relates to the technical field of sand table making, in particular to a laser holographic projection sand table making device. Background technique [0002] Military sand tables generally contain two main parts: one is the bottom tray, and the other is the imitation of mountains and rivers. There are currently two main materials for the production of mountains, rivers and rivers, one is plastic imitations and the other is sand. [0003] Sand tables mainly made of plastic imitations need to be specially customized. First, draw 3D drawings of the real landforms, then 3D print or inject the shapes of the drawings to make the imitations, and then place these imitations on the On a tray, for displaying landscapes to others. On the one hand, this kind of sand table has a long preparation period, and the preparation of the landform needs to be prepared by 3D printing or injection molding, and the scene needs to be prepared; in an emergency sta...
