360-degree visible direct interaction type true three-dimensional virtual display system

Abstract

The invention relates to a 360-degree visible direct interaction type true three-dimensional virtual display system. A Kinect device is arranged at an upper suspender of a bracket; two parabolic reflectors are located right below the Kinect device; the opening of one parabolic reflector is upward, the other parabolic reflector is arranged at the upper end of the parabolic reflector, and the center of each parabolic reflector is located at the focal point of the other parabolic reflector; a visual limit divergence device forms a 45-degree angle with the horizontal plane, and a target object is placed below the visual limit divergence device; the lower parabolic reflector is fixed on a hollow rotating table, and the rotating table is further connected with an optical rotary synchronous monitor; an infrared thermal reflector is placed below the rotating table, and a 150mm convex lens is placed below the infrared thermal reflector; and the lens center of a DMD high speed projector is aligned to the centers of the two parabolic reflector having the same size. The invention further provides a gesture recognition method. The 360-degree visible direct interaction type true three-dimensional virtual display system provided by the invention realizes the direct interaction of a user and an imaging object and enhances the user experience in true three-dimensional display and application.

Description

technical field [0001] The invention relates to a 360-degree visual direct interactive true three-dimensional virtual display system, which belongs to the technical field of three-dimensional space human-computer interaction. Background technique [0002] True 3D Display Technology (True3DVolumetricDisplayTechnique) is the latest research direction in naked-eye stereoscopic display. Observers can observe stereoscopic images with physical depth of field at any angle without wearing any special devices, which conforms to people's real feelings of observing the world and satisfies all physiological and psychological depth hints. True three-dimensional display technology can provide 360-degree naked-view stereoscopic imaging, and the human-computer interaction technology based on this has also attracted the attention of researchers. Interactive true 3D display technology has broad application prospects and great strategic value in many fields such as computer-aided design, mult...

Problems solved by technology

[0004] However, most of the current display systems cannot allow the user to directly interact with the display object. Generally speaking, these systems will use glass covers or other transparent plastic covers to separate the user from the display object. This is mainly because some of the display objects It is in a state of motion, or some devices are dangerous to the user, so their research direction is mainly focused on the interaction around the display object, and it is impossible for the user to directly interact with the display object, which will hinder the user's real experience of the three-dimensional object
