Problems solved by technology

For example, when picking up a virtual cup by hand, part of the cup needs to block the palm, and part of the palm needs to block the cup, such as figure 1 As shown in (a) in , however, the existing augmented reality display device is only used to display virtual images, and does not edit the real scene light field corresponding to the real object so that it can be matched with the virtual scene, such as figure 1 As shown in (b), the existing enhanced display shows that when the real palm picks up the virtual cup, the part of the palm that should be blocked is not processed, which reduces the authenticity of the user experience

Embodiment Construction

[0028] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0029] The present invention firstly provides a solution capable of editing real-scene light fields. The real-scene light field editing scheme of the present invention mainly converts the light emitted by the real-scene light field into polarized light, and then adjusts the polarization state of the polarized light according to the actual needs, so that the adjusted polarized light passes through the analyzer The formed light field is close...

Abstract

The present invention discloses a light field editing device, system and method and a light field display system and method, wherein the light irradiated from an object passes a first polarizer to become the polarized light of a first polarization direction, a first spatial light modulator is placed before the first polarizer optically and carries out the polarization state modulation on the polarized light of the first polarization direction passing the first polarizer, and then the light is emitted out. A first analyzer is placed before the first spatial light modulator optically, and the light modulated by the first spatial light modulator is emitted out via the first analyzer. Under the polarization state modulation action of the first spatial light modulator, the light field of the light emitted out from the first analyzer approaches a desired display light field, so that a real scene light field can be edited.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a light field editing device, system and method, and a light field display system and method. Background technique [0002] In augmented reality display, there is a certain positional relationship between the virtual objects in the displayed virtual scene and the real objects in the real scene. Sometimes it is necessary for the virtual objects to block the real objects in order to have a real visual effect. For example, when picking up a virtual cup by hand, part of the cup needs to block the palm, and part of the palm needs to block the cup, such as figure 1 As shown in (a) in , however, the existing augmented reality display device is only used to display virtual images, and does not edit the real scene light field corresponding to the real object so that it can be matched with the virtual scene, such as figure 1 As shown in (b), the existing enhanced display...
