Abstract

The invention discloses a fast integrated image generation method and a naked-eye three-dimensional display system interacting with users. The generation method includes: inputting external parameters including the viewing distance measured by the depth camera; calculating the viewing width and unit image width according to the viewing distance, and then determining the position of each viewpoint, and then obtaining optimized light field light; calculating the drawing parameters, Pack and cluster light field rays to generate multiple ray clusters to ensure that all rays in a ray cluster form a viewing cone; process multi-viewpoint images in parallel; use pixel rearrangement method to draw and generate unit image arrays, and increase the pixel width of the display panel The modulation is the quotient of the pitch of the lens array and the number of multi-ray clusters. The present invention can quickly draw EIA for large-scale three-dimensional data in real time, and the present invention can realize an interactive three-dimensional display system to maximize the area of ​​the best viewing area.

Description

technical field [0001] The invention relates to a fast integrated image generation method and a naked-eye three-dimensional display system interacting with users. Background technique [0002] 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 high-resolution LCD panel and a lens array. A two-dimensional image is displayed on the LCD, and this two-dimensional image is called an elemental image array (Elemental image array: EIA). Through the refraction of the lens array, different parts in the EIA are refracted to ...

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

[0010] 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
