Three-dimensional light field image generation method and device

Abstract

The embodiment of the invention provides a three-dimensional light field image generation method and device. The three-dimensional light field image generation method comprises the steps: obtaining the actual coordinate value of the center point of each lens; respectively taking the central point of each lens as an original point, and obtaining Wigner-Schnez primitive cells corresponding to each lens, wherein the starting point of the pixel sight of each sub-pixel is the central point of the sub-pixel, and the starting point of the pixel sight direction of the sub-pixel is the central point ofthe lens corresponding to the Wigner-Schwarz primitive cell covering the sub-pixel, and the terminal point of the pixel sight direction of the sub-pixel is the central point of the sub-pixel. The three-dimensional light field image generation method and device can correct the display error of the integrated imaging display system caused by the position deviation of the lens array in the realization process of light tracking, and can generate a three-dimensional light field image with a large viewing angle and multiple viewpoints under the arrangement of different lens arrays of different display devices, so that the definition and reality sense of a three-dimensional imaging effect are improved.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional display, in particular to a method and device for generating a three-dimensional light field image. Background technique [0002] Integrated imaging technology is a commonly used method to realize 3D display. Integrated imaging technology was proposed very early and has a good prospect. [0003] In the prior art, the traditional integrated imaging technology includes two steps: 1. acquisition; 2. display. Among them, during the acquisition process, each lens or pinhole will record the collected objects, which are called element images, and a large number of small and side-by-side element images will be imaged on the recording device behind the lens array to obtain a three-dimensional light field image. In the display process, the three-dimensional light field image is firstly displayed through the LCD, and a microlens array is arranged in front of the LCD, and the viewer can se...

Problems solved by technology

In practical applications, limited by the precision of the microlens array processing technology, the arrangement of the microlens array cannot be absolutely neat and uniform, resulting in uneven arrangement of the microlens array and a gap in the distance from the original point.

As a result, the stereoscopic imaging effect is not clear and the technical problems of poor realism
