Problems solved by technology

[0005] The traditional grating autostereoscopic display is limited by the parameters of the cylindrical lens / slit and the resolution of the two-dimensional display screen, and there is a problem that the number of viewpoints and the stereoscopic resolution are mutually restricted. The fewer parallax images, correspondingly, the narrower the parallax range of the 3D scene that can be viewed
Kinect is a somatosensory camera developed by Microsoft. It has functions such as real-time motion capture and image recognition. Using Kinect to interact with grating autostereoscopic displays can solve the problem of narrow parallax range in viewing 3D scenes. However, such interactive systems are mostly aimed at virtual reality. 3D scenes, there are few autostereoscopic display systems that interact with real 3D scenes

Embodiment Construction

[0031] A typical embodiment of an interactive autostereoscopic display method for a real three-dimensional scene of the present invention is described in detail below, and the present invention is further described in detail. It is necessary to point out that the following examples are only used to further illustrate the present invention, and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art make some non-essential improvements to the present invention according to the above-mentioned content of the present invention. and adjustment, still belong to the protection scope of the present invention.

[0032] The acquisition process of the super multi-view parallax information of the real scene, firstly adjust the camera array pose, arrange N=64 cameras at equal intervals in the horizontal direction, and adjust the pose of each camera, so that the light of all cameras is adjusted. The axes converge at one point. In orde...

Abstract

The invention provides an interactive free three-dimensional display method for a real three-dimensional scene. The method comprises three processes of obtaining ultra-multi-view parallax informationof the real scene, generating an ultra-multi-view micro image array sequence and performing gesture interactive three-dimensional display. According to the method, a camera array is used to obtain ultra-multi-view parallax information of a real three-dimensional target scene, Kinect somatosensory equipment is used to detect a gesture signal sent by a viewer, switching display of the parallax information of the three-dimensional target scene is achieved, and the ultra-multi-view information of the real three-dimensional scene is viewed in a main view area.

Description

[0001] 1. Technical field [0002] The invention relates to an autostereoscopic display technology, in particular to an interactive autostereoscopic display technology for a real three-dimensional scene. [0003] 2. Background technology [0004] Autostereoscopic display technology is a display technology that can view stereoscopic images within a certain range without wearing any auxiliary equipment. The grating-based autostereoscopic display places a cylindrical lens grating / slit grating with certain parameters in front of the two-dimensional display screen, and uses the grating to block or refract light to form a series of viewpoints. When the eyes are at different viewpoints, that is, Corresponding parallax images can be viewed, and stereoscopic perception is formed after brain fusion. [0005] The traditional grating autostereoscopic display is limited by the cylindrical lens / slit parameters and the resolution of the two-dimensional display screen, and there is a problem ...
