A stereoscopic image display machine based on interactive teaching

Abstract

The invention discloses a three-dimensional image display machine based on interactive teaching, comprising an imaging part, a retractable part, a rotating part and a lifting part arranged in sequence from bottom to top; when working, a linear push rod motor of the three-dimensional image display machine converts the three-dimensional image The display machine is lowered to the level of sight, and then the square crank drives the connecting rod to rotate by controlling the stepping motor of the stereoscopic image display machine, so that the guide rail is extended, and the trapezoidal frame and the plexiglass plate fixed on it are opened. Make an angle of 45 degrees with the horizontal plane, and then control the stepping motor of the stereoscopic image display machine to make the stereoscopic image display machine rotate, and turn on the liquid crystal display at the same time. Stereoscopic images on four different sides; when not in use, the stereoscopic image display machine is folded and raised to the ceiling to save classroom space. The invention has many advantages such as low cost, multi-function, high use performance and the like.

Description

【Technical field】 [0001] The invention relates to a classroom projection device, in particular to a three-dimensional image display machine based on interactive teaching. 【Background technique】 [0002] The relevant patent that has been authorized is: a 360-degree floating three-dimensional phantom imaging system, the patent publication number is: CN202854478U, and the publication date is: April 3, 2013; its content is briefly described as follows: [0003] A 360-degree floating three-dimensional phantom imaging system includes a stereoscopic imaging device and a control processing device, the stereoscopic imaging device is connected to the control processing device through a guide line, and at least one glass plate is obliquely arranged on the stereoscopic imaging device, Each of the glass plates is provided with a corresponding projection device in an oblique direction, the projection device is placed on the stereoscopic imaging device, and the surface of the glass plate f...

AI Technical Summary

Problems solved by technology

However, the current three-dimensional projection technology only stays in the simple, primitive, and imperfect product stage. There is only the imaging part, and there is no way to realize various necessary functions, such as rotation, lifting, and folding, and has no practical application value.

Therefore, there is no way to really introduce the teaching system, and the purpose of serving the classroom cannot be achieved
