Embodiment Construction

[0032] A preferred example of the present invention is described as follows in conjunction with accompanying drawing:

[0033] Referring to Fig. 1, this free stereoscopic display system based on light field and binocular vision technology consists of a set of CCD camera arrays (2), a computer with a multi-channel image acquisition card and a digital input I / O control card ( 3), an embedded processor (4) capable of dual-channel image acquisition and having a serial output port, a 3D display device (6), a set of rotation and movement control system (8), two CCD cameras ( 5), two projectors (9) form.

[0034] Wherein, the computer (3) is connected with the camera array (2) through an image acquisition card, and connected with two projectors (9) through a display card. The embedded processor (4) is connected with the CCD (5) through a video interface. The projector projects the image onto the 3D display terminal (6), and the computer (3) is connected with the rotation and moveme...

Abstract

The disclosed free stereo display (FSD) system is composed of three systems: the system for obtaining and reconstituting 3D scene or optical field of object, the system for obtaining space positions of human eyes, and 3D display system. FSD method includes procedures: first, using technique of optical field obtains and builds database of optical field of stereo scene; next, using binocular visiontechnique (BVT) realizes realtime tracking and accurate positioning eyes of the observer, and calculating coordinates of space positions of two eyes; the positions of two eyes are equivalent to two viewpoints in space, which are inputted into computer; using optical field reconstitution technique to pick up views from two viewpoints so as to form two images with parallax, which are transferred totwo projectors, and are projected to solid screen; thus, observer can observe 3D image of scene on 3D display screen. When position of observer changes, BVT can track the change in realtime.

Description

technical field [0001] The present invention relates to an autostereoscopic display system and method, in particular to a display system and method based on light field technology and binocular vision technology that can observe stereoscopic images in a larger field of view. Background technique [0002] The research on 3D display technology has gone through many years of development and has achieved fruitful results. Three-dimensional display technologies mainly include stereoscopic technology (Stereoscopic), automatic stereoscopic technology (Auto stereoscopic), volumetric three-dimensional display technology (Volumetric Display), and holographic three-dimensional display technology (ElectronicHolography). Among them, stereoscopic technology and free stereoscopic technology are the most widely used. Stereo mirror technology needs to wear a helmet display or 3D stereo glasses, which will inevitably reduce the entertainment, comfort and nature of the observation display tes...
