Embodiment Construction

[0035] (1) In the integrated imaging system, the collection microlens array is 45×53 microlenses arranged in a square, the focal length of the microlens is f=3.0mm, the width of the microlens is P=1.08mm, and the element image collected by the CCD camera The collection is 45 rows×53 columns (H=45, W=53), each element image has 40×40 pixels (M=40), and the distance between the element image collection plane and the microlens array is g=3.5mm , the distance between the 3D object and the microlens array is z=21mm;

[0036] In the element image collection collected by the CCD camera, first determine an element image as the initial element image, and then select the element image at N intervals to obtain the selected element image set ES;

[0037] First, how to determine the period N value, such as figure 2 As shown, the element image collection collected by the CCD camera is placed on the element image collection plane, with N as the period, some element images are selected at i...

Abstract

The invention relates to a method for increasing the reconstruction resolution ratio of a computer integrated images, belonging to the technical field of image processing. An elemental image set is periodically selected during computer reconstruction by adequately utilizing the characteristic that adjacent elemental images in integrated imaging have a part of similar information, and a plurality of pixels are extracted from each of the selected elemental images to be spliced, so that the final reconstructed image is obtained. According to the method, the resolution ratio of the computer reconstructed image is increased.

Description

technical field [0001] The invention belongs to the technical field of image processing, relates to three-dimensional image processing, is a method for improving the resolution of computer reconstruction in an integrated imaging system, and can be used for three-dimensional display of target scenes in integrated imaging. Background technique [0002] Integrated imaging (Integral Imaging, II) technology is an image technology that records and displays 3D spatial scene information through a microlens array. II system includes acquisition and display parts, respectively as Figure 1a and Figure 1b shown. [0003] In the acquisition part, the object is imaged through a microlens array, and each element lens forms a corresponding image of the object, called an element image, and these element images are imaged by a high-definition CCD camera; in the display part, the collected element images are located on the display On the flat panel, the original three-dimensional optical s...
