A method and system for determining the position and diffusion angle of a directional scatterer

Abstract

The present invention provides a method and system for determining the position and diffusion angle of a directional scatterer. The determination method includes the following steps: obtaining the parameters of the lens array of the light field display system based on integrated imaging, and the distance between the display and the lens array; The parameters of the lens array and the distance between the display and the lens array determine the position of the directional scatterer by determining the parallax of the same-named image points in different unit images; according to the position of the directional scatterer and the distance of the lens array Parameter, according to the principle of light scattering, determines the diffusion angle of the directional scatterer. The invention realizes the quantitative determination of the diffusion angle of the directional scatterer, the decoupling of the position of the directional scatterer from the depth center plane, and the dynamic determination of the position of the directional scatterer based on the spatial position of the display object, thereby realizing the clear display of scenes with a large depth range.

Description

technical field [0001] The invention relates to the technical field of integrated imaging, in particular to a method and system for determining the position and diffusion angle of a directional scatterer. Background technique [0002] Traditional integrated imaging technology uses densely arranged microlens arrays to regulate light, and the field of view displayed by it is very limited, which affects people's viewing experience. The light field display based on integrated imaging uses a lens array composed of relatively large lenses (usually ≥ 2mm) to control the light, restore a sparse and discrete light field, and then use the angular spectrum diffusion characteristics of the directional scatterer. Adjust the discrete light field twice to restore the continuous light field. It can bring a better three-dimensional display experience. The selection of the diffusion angle of the directional scatterer and the determination of the placement position of the directional scatter...

AI Technical Summary

Problems solved by technology

The selection of the diffusion angle of the directional scatterer and the determination of the placement position of the directional scatterer in the light field display system based on integrated imaging are very important. If it is not determined properly, the image will be blurred and the viewing experience will be affected. However, there is currently no method for quantitatively determining the diffusion angle. And the current placement of directional diffusers is assumed to be on the depth center plane, which has a certain error from the actual position that should be placed, which also affects the visual experience
