Problems solved by technology
[0003] Since there are a large number of natural phenomena, mountains, rivers, geological structures, and ocean currents in geography teaching, it is impossible for students to get an intuitive feeling only through textbook content and teachers' narration. The current naked-eye 3D projection equipment is also used in teaching. Glasses-free 3D projection equipment is applied to geography teaching. In the classroom, naked-eye 3D technology can be used to display the teaching of natural geographical phenomena and simulated geographical phenomenon experiments, so that students can understand the course knowledge more intuitively. However, the existing naked-eye 3D The cost of projection equipment is too high, and the cost of covering the whole range of classrooms is too high

The invention relates to naked eye 3D projection equipment for geography teaching, and belongs to the technical field of projection equipment. The naked eye 3D projection equipment comprises a transverse rail, a vertical moving mechanism, a naked eye 3D projection device, a transparent cover and a protective cover. The transverse rail is installed above a blackboard in a classroom, the vertical moving mechanism slides on the transverse rail through the sliding block and vertically rotates relative to the sliding block, the transparent cover is arranged on the outer surface of the naked eye 3D projection device, the protective cover is arranged on the outer surface of the transparent cover, and the naked eye 3D projection device slides on the vertical moving mechanism through the protective cover. The naked eye 3D projection device is provided for geography teaching, a teacher only needs to carry the naked eye 3D projection device in class, the naked eye 3D projection device is installed on the vertical rail on the blackboard in class, the naked eye 3D projection device can move left and right and up and down, the angle can be adjusted, and a weak light environment beneficial to projection can be created.
Description
technical field [0001] The invention belongs to the technical field of projection equipment, and in particular relates to a naked-eye 3D projection equipment for geography teaching. Background technique [0002] Glasses-free 3D technology utilizes the parallax characteristic of human eyes, and can obtain realistic stereoscopic images with space and depth without any auxiliary equipment, such as 3D glasses, helmets, etc. Glasses-free 3D projection equipment can be designed into three-dimensional and wall-mounted types, so that glasses-free 3D can be placed directly on the ground or mounted on the wall, which can maximize space utilization. [0003] Since there are a large number of natural phenomena, mountains, rivers, geological structures, and ocean currents in geography teaching, it is impossible for students to get an intuitive feeling only through textbook content and teachers' narration. The current naked-eye 3D projection equipment is also used in teaching. Glasses-fr...
