Fast integrated image generation method and naked eye three-dimensional display system interacting with users

Abstract

The invention discloses a fast integrated image generation method and a naked eye three-dimensional display system interacting with a user. The generating method includes: inputting an external parameter including a viewing distance measured by a depth camera; calculating a viewing width and a unit image width according to the viewing distance, and then determining a position of each viewpoint, thereby obtaining optimized light field rays; calculating a drawing parameter, packing and clustering the light field rays to generate a plurality of ray clusters, and ensuring that all the rays in oneray cluster form a view frustum; processing multi-view point images in parallel; and drawing and generating a cell image array through the pixel rearrangement method, and modulating the pixel width ofa display panel into the quotient of the pitch of a lens array and the number of the plurality of ray clusters. The invention can perform fast EIA drawing for large-scale three-dimensional data in real time, and the invention can realize an interactive three-dimensional display system to maximize the area of an optimal viewing region.

Description

[0001] This application is a divisional application of the invention patent application with the application number "201310397971.X" and the invention title "rapidly integrated image generation method and naked-eye three-dimensional display system interacting with users". technical field [0002] The invention relates to a fast integrated image generation method and a naked-eye three-dimensional display system interacting with users. Background technique [0003] Integrated imaging display (Integral imaging display: IID) is a technology that allows users to view natural three-dimensional images with naked eyes. This three-dimensional image has continuous parallax changes in the horizontal and vertical directions. Integrated imaging technology was first proposed by French scientist Lippmann. In recent years, with the advancement of electronic technology, integrated imaging technology has begun to move towards practicality. Basically, an integrated imaging system includes a hi...

Problems solved by technology

The problem in this paper is that the calculation of EIA is completed by multi-pass rendering. When the number of lens units in the lens array is too large, the rendering speed will drop significantly, which cannot meet the needs of real-time applications.

This method improves the viewing performance of the traditional integrated imaging system, but it needs to judge the specific direction of each ray one by one, resulting in a very low speed of drawing EIA

[0011] The problem with the existing technology is that the method of drawing EIA is inefficient, or due to the bottleneck of the method itself, or due to the ineffective use of hardware acceleration means
