Embodiment Construction

[0048] In the following description, for purposes of illustration rather than limitation, specific details such as specific system architectures, interfaces, and techniques are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0049] In the first aspect, an embodiment of the present invention provides a method for controlling a projection sand table system. The projection sand table system includes a projection sand table and a projection device. In an embodiment of the present invention, as figure 1 As shown, the projection sand table system control method includes the following steps:

Abstract

The present invention relates to a projection sand table system control method and apparatus, and a readable storage medium. The projection sand table system control method comprises: acquiring sand table model data corresponding to a target table; acquiring feature point information of the target sand table according to the sand table model data; acquiring elevation data of the target sand tablecorresponding to the feature point information; according to the elevation data, driving a sand pushing device of the projection sand table to perform a sand pushing operation to push sand in the projection sand table to form a target sand table; and when a sand push completion signal fed back by the projection sand table is recognized, issuing a projection instruction for projecting a corresponding target image onto the target sand table to the projection device, so that the projection device can project a target image onto the target sand table according to the projection instruction. According to the technical scheme of the present invention, the problems that by using the existing three-dimensional electronic sand table the user cannot visually observe the sand land topography and thelike are solved.

Description

technical field [0001] The present invention relates to the technical field of projection sand table, in particular to a control method, device and readable storage medium of a projection sand table system. Background technique [0002] As an auxiliary tool for combat research, sand tables have always been valued by army commanders and staff officers. In the period of underdeveloped computer technology, people mainly made physical sand tables by means of physical accumulation to meet the needs of combat research. The information battlefield is changing rapidly. Traditional The physical sand table and marking method can no longer meet the needs of future combat research. With the rapid development of computer technology, there have been products that display 3D electronic sand table through the screen. It can quickly and accurately display 2D and 3D maps and realize linkage. However, due to The existing electronic sand table is displayed through a screen, so there are problem...
