Description
Technical Field
The invention relates to the technical field of true three-dimensional display technology, laser beam modulation technology, optical capture technology, projection technology and automatic control, in particular to a control method for interactive three-dimensional display based on photophoretic capture.
Background
The world in which we live is a three-dimensional world, and the traditional display device can only display two-dimensional plane graphics, and the two-dimensional display lacks depth of field relative to the three-dimensional display. With the rapid development of science and technology, people also put higher demands on the display effect of the display. In recent years, various three-dimensional display technologies have been developed, and can be generally classified into the following technologies: stereoscopy technology (stereoscopy Display), Autostereoscopic three-dimensional Display technology (autostereoscopy 3DDisplay), Holographic Display technology (homographic Di splash), and Volumetric three-dimensional Display technology (Volumetric3 DDisplay).
The stereoscopic technology requires the wearing of special glasses and the realization of a three-dimensional effect by using binocular parallax. This causes the observer to have a limited field of vision and to see the same image when viewed from different angles, without a true stereoscopic impression; the principle of the autostereoscopic three-dimensional display technique is the same as that of the stereoscopic technique, but no special glasses need to be worn. This display technique allows an image to be viewed only from a particular spatial viewing window, so that a set of images can be projected into a series of windows, where the viewer receives different images from the two glasses when viewing, thereby creating a stereoscopic effect. The disadvantage of this display technique is that the range of observation is limited, and it is inconvenient for many people to observe simultaneously. Both of these approaches essentially provide only a psychological depth of field and no physical depth of field. When the eyes observe the images, the focal length of the eyes cannot be changed to observe when the eyes observe a real object, and the three-dimensional effect is synthesized through the brain.
Holographic display technology is based on the recording, analysis and reconstruction of information from the reconstruction of the wavefront of an optical wave. With the development of computer technology, computer holography is also increasingly applied to holographic display technology. However, due to the limitation of the spatial light modulation device, the display quality and the viewing angle of the current computer-generated holographic display technology are greatly limited.
The volumetric three-dimensional display technique is a technique for reproducing image information in a real three-dimensional space. The three-dimensional object displayed by the three-dimensional display technology has both psychological depth of field and physical depth of field. The three-dimensional object can be directly observed by any plurality of observers from any angle without any auxiliary equipment. The existing three-dimensional display technology of the volume in the free space can be divided into the following technologies: laser induced plasma display, modified air display, acoustic levitation display, and the like. Laser-induced plasma display currently cannot achieve color display and the shielding effect of three-dimensional objects in free space. The display effect of the improved air display and acoustic levitation display is too coarse.
The basic unit in a two-dimensional display is a pixel, while the corresponding basic unit in a three-dimensional display technique is a Voxel (Voxel). When the same image is displayed, the more voxels in the activated three-dimensional space, the more details of the displayed three-dimensional image are, the higher the resolution is, and the better the display effect is. In two-dimensional displays, the display of an image is achieved by activating pixels of the display by periodic, rapid scans of the pixels. Also, in volumetric three-dimensional display techniques, some way is required to scan voxels in three-dimensional space to achieve a display of a three-dimensional image.
In laser induced plasma display, laser light is focused through a lens to ionize air, so that the air can be observed by human eyes. By controlling the focus of the laser, rapid scanning is performed in a three-dimensional space, thereby realizing the display of a three-dimensional graph. This display technology requires a laser having a high energy, and the color of light emitted by ionization of air is related to the kind of gas ionized in air, so that it is difficult to realize color display.

Example 4: three-dimensional capture
The embodiment provides a control method of an interactive three-dimensional display device based on optical electrophoresis capture, which comprises the following steps: the image to be displayed is a three-dimensional image (such as a complex three-dimensional portrait), and the user selects to capture the particles three-dimensionally through an upper computer; then, a user adjusts the power of the laser through the upper computer, and controls the light modulator 1 to modulate the light beam, so that the light beam can generate a three-dimensionally arranged light bottle structure at a focus, and the light beam captures the particles through controlling the three-dimensional scanning system 1 and the particle container in the process of sequentially passing through the three-dimensional scanning system 1 and the particle container. After the particles are captured, a user controls the three-dimensional scanning system 1 through the upper computer to control the light beam to carry the particles to perform rapid scanning in the display area, at the moment, if a three-dimensional outline image needs to be displayed, the particles are directly controlled to be arranged according to the outline required to be displayed, then, the projection system is used for projection, if the three-dimensional outline image required to be displayed is too large, the image required to be displayed can be divided and displayed in turn, and when the speed is fast enough, a complete three-dimensional outline image can be observed. When the particles are scanned, the upper computer controls the RGB laser system, the light modulator 2 and the three-dimensional scanning system 2, when the three-dimensionally arranged particles are scanned to a certain position, the projection system divides colors required to be displayed in a linear region where the particles are located into three frames, the single combined RGB laser system respectively projects the three colors onto the particles through the light modulator 2 by utilizing three-dimensional holographic projection, or the RGB laser system consisting of green, red and blue lasers which are not combined is modulated by the three light modulators and then simultaneously projects the three colors onto the particles through the three-dimensional scanning system by utilizing three-dimensional holographic projection. The light beam impinging on the particles is scattered and the desired displayed colour is observed at that point. When the speed of scanning is sufficiently fast, the displayed image can be observed in the display area.
In the process of image display, a user can also recognize information such as the position and the action of a human body through the interactive system and transmit an instruction to the upper computer according to the recognition result, and the upper computer adjusts the position scanned by the particles by controlling the light modulator and the three-dimensional scanning system in the particle control system and the projection system according to the position information of the human body, so that the angle of image display is changed, and the optimal viewing effect is realized; and the upper computer controls the particle control system and the light modulator and the three-dimensional scanning system in the projection system according to the action information of the human body, and adjusts the displayed graph to realize interaction.
The user can also carry out real-time detection through the display quality detection device to judge whether the display quality meets the requirements. When the display quality is detected to be reduced or not meet the requirements in the working process of the display system, the laser power, the scanning speed, the microparticles recapture and the like are controlled by the upper computer to ensure that the light beam can stably carry enough microparticles to scan in the space, so that the display quality is optimized.
In summary, when the image to be displayed is relatively simple and the required resolution is relatively low, the single-point capturing mode may be selected, but if the image is relatively complex and the required resolution is relatively high, the frame rate of display may be greatly reduced due to the limitation of the particle motion speed, which affects the viewing effect, and therefore, other modes, such as one-dimensional, two-dimensional and three-dimensional capturing, may be selected to increase the frame rate of display. Therefore, the interactive three-dimensional display device and the control method thereof provided by the specific embodiment of the invention can realize 360-degree full-view naked eye three-dimensional image display in free space and interaction, and can also greatly improve the three-dimensional display effect.
