Method for obtaining naked-eye 3D composite graph based on normalized infinite viewpoint

Abstract

The invention discloses a method for obtaining a naked-eye 3D composite graph based on normalized infinite viewpoint, wherein the method comprises the steps: calculating a maximum parallax matrix anda normalized viewpoint matrix according to an input 2D image and a depth-of-field image; traversing the synthesized image pixel point, comparing the normalized viewpoint value of the synthesized imagepixel point with the reference viewpoint, and determining the virtual viewpoint as the left / right extension of the reference viewpoint; calculating the parallax coefficient of the pixel points of thesynthesized image according to the relationship between the normalized viewpoint matrix and the reference viewpoint; obtaining a maximum absolute value in the matrix according to the maximum parallaxmatrix; and carrying out region traversal on the 2D image according to the parallax coefficient, and carrying out pixel filling by adopting an addressing matching method to realize naked eye 3D composite image acquisition. According to the method, the synthetic graph for naked-eye 3D display is obtained by combining the normalized infinite viewpoint and inverse matching based on local traversal,so that the occupied space of an algorithm on a computer memory is reduced, and the processing speed is increased. The method can be effectively applied to a three-dimensional display in which a cylindrical lens array is not matched with pixels.

Description

technical field [0001] The invention belongs to the technical field of image source acquisition for stereoscopic display, and in particular relates to a method for acquiring naked-eye 3D synthetic images based on normalized infinite viewpoints. Background technique [0002] In recent years, 3D imaging and display technology has received more and more attention. Since the integrated imaging technology based on microlens array has complete parallax, continuous viewpoint and does not require any observation glasses and special lighting, this technology stands out in the field of 3D imaging and display technology, and gradually develops into the most potential and promising autostereoscopic display. technology. [0003] The 3D display system completely reproduces the 3D information of the scene and displays images with a sense of depth. The viewer can directly see the distance of each object in the scene, and quickly and intuitively gain insight into the three-dimensional spat...

Problems solved by technology

[0004] At present, there are many ways to obtain stereo composite images in the industry, such as the pixel forward matching algorithm proposed by Philips, but this algorithm is not only time-consuming, but also requires More memory usage

Another example is the patent 201410041134.8, which proposes a weighted-based image synthesis algorithm, which is still based on the traditional image forward synthesis, which takes up a lot of processor memory.
