Embodiment 1

[0042] Example 1: Single point capture

[0043] This embodiment provides a control method for an interactive three-dimensional display device based on photophoretic capture, which includes the following steps: the image to be displayed is a three-dimensional image (such as a relatively simple three-dimensional portrait), and the user selects the three-dimensional image through the host computer. Single-point capture of particles; then the user adjusts the power of the laser through the host computer, and controls the light modulator 1 to modulate the beam so that it can generate a single light bottle structure at the focal point, and the beam passes through the three-dimensional scanning system 1 and the particles in turn During the container process, the particle capture is realized by controlling the three-dimensional scanning system 1 and the particle container. After the particles are captured, the user controls the 3D scanning system 1 through the host computer to control...

Abstract

The invention provides an interactive body three-dimensional display device based on photophoresis capture and a control method thereof. The device comprises a particle control system, an upper computer, a projection system and an interaction system. The particle control system comprises a laser, a light modulator 1, a three-dimensional scanning system 1 and a particle container; the projection system comprises an RGB laser system, a light modulator 2 and a three-dimensional scanning system 2; wherein the upper computer is respectively connected with the laser, the light modulator 1, the three-dimensional scanning system 1, the particle container, the RGB laser system, the light modulator 2 and the three-dimensional scanning system 2; the interaction system is connected with the upper computer; the interaction system is used for identifying the position and action information of the human body and transmitting an instruction to the upper computer according to an identification result,and the upper computer optimizes the viewing angle and interacts by adjusting the particle control system and the projection system. According to the invention, wide-color-gamut, high-resolution and low-speckle true three-dimensional imaging in a free space can be realized, and the system safety and the cost are more advantageous.

Description

technical field [0001] The present invention relates to the fields of true three-dimensional display technology, laser beam modulation technology, optical capture technology, projection technology and automatic control technology, and specifically relates to an interactive three-dimensional display device based on photophoretic capture and a control method thereof. Background technique [0002] The world we live in is a three-dimensional world, and traditional display devices can only display two-dimensional graphics. Compared with three-dimensional displays, two-dimensional displays lack depth of field. With the rapid development of science and technology, people have put forward higher requirements for the display effect of the display. In recent years, people have developed a variety of 3D display technologies, which can generally be divided into the following categories: Stereoscopic Display, Autostereoscopic 3D Display, Holographic Display, and Volumetric 3D Display te...
