Problems solved by technology

[0004] The traditional computational reconstruction method of integrated imaging orthogonal view is to extract the pixels at the same position in each element image to synthesize the orthogonal view according to the reconstruction angle of view. The number of orthogonal view pixels is equal to the number of microlenses, so the reconstruction The orthographic view has a lower resolution

Abstract

The invention discloses a calculation and reconstruction method of an integrated imaging orthogonal view. The method mainly comprises the following two steps: determining the position and size of an image block extracted from each element image according to parameters of an integrated imaging system; and the extracted pixels in each image block are rotated by 180 degrees and are spliced in sequence, so that a high-resolution orthogonal view can be reconstructed. According to a traditional calculation reconstruction method, pixels at the same position are extracted from each element image to synthesize an orthogonal view, the number of the pixels in the orthogonal view is equal to the number of microlenses, and therefore the resolution of the reconstructed orthogonal view is low. Accordingto the calculation and reconstruction principle of the integrated imaging orthogonal view, the image blocks composed of the multiple pixels are extracted from each element image to be synthesized, andtherefore the resolution of the calculation and reconstruction orthogonal view is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional image processing, and relates to a calculation and reconstruction method of an integrated imaging orthogonal view, which can be used in an integrated imaging system to display orthogonal images of different viewing angles of a target scene on a computer. Background technique [0002] Glasses-free stereoscopic display technology is a research hotspot in the field of display. The 3D display technology based on integrated imaging (Integral Imaging) can allow observers to watch continuous and jump-free true 3D stereo scenes without wearing auxiliary viewing equipment, and there is no visual fatigue. Display, 3D image visualization and other fields have broad application prospects and important research value.
