Abstract

The invention discloses a device for realizing space body three-dimensional display by using an air screen, which comprises an addressing type air screen generator, a DLP projector, a reflecting mirror group, a device shell, a gear, a motor, a toothed belt, a rotating shaft, a connecting component, a linkage lever and the like, wherein the rotating shaft is provided with the DLP projector, the gear and the connecting component; the gear is connected with the motor through the toothed belt; the connecting component is connected with one end of the linkage lever, while the other end of the linkage lever is provided with the reflecting mirror group corresponding to the DLP projector; and the addressing type air screen generator is arranged above the rotating shaft. The device realizes a bodythree-dimensional display mode without a rotary screen and a rigid or flexible display screen; only the air screen is exposed outside the device, and all other components are arranged in the shell; and the device is safe and convenient to operate, and can realize the touch of three-dimensional images without any secondary imaging conversions.

Description

technical field [0001] The invention relates to three-dimensional display technology, in particular to a three-dimensional display device based on an air screen. Background technique [0002] The three-dimensional display technology is different from the two-dimensional display method, it has an intuitive image display effect, and can provide rich and real image information. Three-dimensional technology can be divided into true three-dimensional display and false three-dimensional display. False three-dimensional display requires the help of corresponding observation glasses, and its application fields are quite limited. The development of 3D technology today generally includes holographic 3D display, volumetric 3D display, and stereoscopic 3D display. The practical application and development of holographic three-dimensional display is limited due to the huge amount of data processing. Other 3D display methods are mostly based on rotating screens, that is, based on rigid...
