Element image rapid generation method of integrated imaging system

Abstract

The invention provides an element image rapid generation method for realizing integrated imaging display by using depth information and a scene 2D picture. According to an existing element image generation method, many-to-one mapping is established from a scene to an element image, and a large number of redundant calculations exist. According to the method, single-point mapping from the element image to the scene is established, each pixel in the element image only corresponds to a unique scene pixel, the matching precision is high, and holes at the depth step are eliminated. The time complexity of the method is mainly controlled by the sum of pixels of the element image array, the calculation and generation speed of the element image is more than 7 times that of other traditional methods,and the larger the total number of the pixels of the scene is, the more obvious the speed advantage of the method is.

Description

technical field [0001] The invention relates to an integrated imaging technology, in particular to a method for rapidly generating an element image array of an integrated imaging system. Background technique [0002] Integrated stereoscopic imaging is a stereoscopic display technology that reproduces 3D scenes through lens arrays. There are two main links: information collection of 3D scenes and stereoscopic light field reproduction. The elemental image array is one of the key factors affecting the quality of the reproduced light field. There are two main techniques for generating elemental image arrays, acquisition with optical devices and computer generation. Using microlens arrays or camera arrays to collect data has many problems such as complex equipment and signal crosstalk. The method of generating element images by computer needs to establish a 3D scene model, which is difficult to meet the needs of real-time display. In addition, the depth data collected by the d...

Using microlens arrays or camera arrays to collect data has many problems such as complex equipment and signal crosstalk

The method of generating element images by computer needs to establish a 3D scene model, which is difficult to meet the needs of real-time display

In addition, the depth data collected by the depth camera and the scene color map can be used to generate element images. This method is to establish a function mapping from the 3D scene to the element image array, which is a many-to-one matching relationship, resulting in slow calculation speed and the element image There will be holes at the discontinuity of the corresponding scene depth, and the image quality of the element is low
