Description

Technical Field

[0001] The utility model relates to the technical field of digital sand tables, in particular to a 3D naked-eye digital sand table for a multimedia exhibition hall. Background Art

[0002] Digital sand table is a modern high-tech means based on computer technology to generate realistic three-dimensional image models. With the help of projection display equipment or other display equipment, the three-dimensional or four-dimensional graphic image models on the computer are displayed on the table. It is widely used in exhibition halls. However, the existing projection sand table cannot adjust the height of the sand table when in use, and the angle of the projection device cannot be adjusted, resulting in incorrect projection. Sometimes the picture is distorted and affects the viewing effect.

[0003] To this end, the utility model patent with publication number CN219800384U discloses a digital sand table large-screen projection interactive system, including an interactive table, a sand table body, a projection bracket, a projection fixture, a projection device, a lifting threaded rod, a fixing block, a lifting slider, a lifting support rod, a driving slot, a lifting gear and a lifting motor, wherein the sand table body is arranged above the interactive table, the projection bracket is fixed to one side of the interactive table, the projection fixture is fixed to the upper end of the projection bracket, the projection device is arranged on one side of the projection fixture, one end of the projection device is rotatably arranged in the projection fixture, and the lifting threaded rod is rotatably arranged above both ends of the interactive table. The utility model belongs to the field of digital sand table technology, and specifically provides a digital sand table large-screen projection interactive system that can meet different projection distance requirements and improve projection quality by adjusting the height of the sand table, and the projection device can be adjusted in angle to meet different projection pictures and improve the interactivity of the sand table, and has strong practicality;

[0004] However, in actual use, we found that since it is set up in a public place, dust is easily raised by people coming and going. A large number of small particles of dust float in the air, and the possibility of adhering to the lens increases, which can easily affect the projection quality. In addition, the lifting structure set up in the above device does not have a protective structure. When the lifting part moves downward, it moves relative to the base, and there is a certain safety hazard if there are people around. Utility Model Content
