Non-contact man-machine interactive space 3D display device and display control method

Abstract

The invention discloses a non-contact man-machine interactive space 3D display device and a display control method. A composite technique of combining infrared control and image identification is adopted. An infrared control technique is that infrared ray signals received by a receiver are changed through influencing propagation of infrared rays, further digital signals output by the receiver generate hopping transition, the signals are input in a computer 4, and therefore, corresponding assemblies of a video player are controlled. The image identification technique is that when fingers go deep into a special region, an image collection camera photographs images of collected gestures and transmits the images to the computer through a USB interface, a built-in function is invoked by the computer for identifying and analyzing the transmitted images and changing the images on the display screen, and a purpose of controlling the images by an audience is realized. The method and the device have the advantages that non-contact interaction is realized by using simple and available raw materials, the numbers of transmitting tubes and receiving diodes are increased, more complex gestures can be identified, and the method and the device has great development prospects.

Description

technical field [0001] The invention belongs to the field of spatial holographic display, and relates to an interactive holographic technology for human gesture recognition, in particular to a non-contact human-computer interaction spatial 3D display device and a display control method. Background technique [0002] Holographic projection is one of the popular stereoscopic projection technologies in recent years, and is widely used in model display, sand table simulation and virtual experience. It uses the principle of interference and diffraction to record and reproduce the real three-dimensional image of the object. The audience can watch the three-dimensional virtual scene without wearing 3D glasses. The holographic projection technology completely subverts the traditional display effect. It shows a illusory Yizhen's three-dimensional space injects the flying charm of the display target into the dreamlike and poetic scene, forming a charming and suffocating three-dimensio...

Problems solved by technology

[0003] However, there is a fatal flaw and deficiency in this technology, that is, the display images of the imaging system must be stored, and the playback order cannot be changed, and the audience cannot perform specific operations on the formed images according to their own needs, that is, it cannot realize In the interaction between people and 3D images, people can only receive information passively, which will greatly restrict the application and popularization of this imaging system
