Embodiment Construction

[0030] For the convenience of explanation, the mathematical symbols used are stipulated as follows:

[0031] i and j represent the horizontal and vertical position index of the pixel, respectively;

[0032] m and n represent the horizontal position index offset and vertical position index offset of the pixel respectively, ranging from -1 to 1, so the 8 pixel position indices adjacent to each pixel can be represented by i+m and j+n;

[0033] Gray(i, j) represents the pixel value of the pixel point.

[0034] see image 3 , the improved calculation integrated image high-resolution reconstruction method of the present invention comprises the following steps:

[0035] Step 1, use the virtual pinhole array to map the pixel points of the element sub-image.

[0036] Pixel mapping process such as Figure 4 As shown, the number of virtual pinholes is the same as the number of element sub-images, and the arrangement of the pinhole array corresponds to the position distribution of the...

Abstract

The invention discloses an improved high-resolution reconstruction method for calculating an integrated image, mainly solving the problem that the existing reconstruction method of calculating the integrated image has low resolution of a reconstructed image and high complexity of reconstruction. The improved high-resolution reconstruction method comprises the steps that: element subimage pixel points are mapped on a reconstructed image plane by a virtual pinhole array, and a discrete point-mode planar image consisting of zero pixel points and non-zero pixel points is reconstructed; the non-zero pixel points in the image are judged in a point-by-point manner, and pixel values thereof are superimposed on the zero pixel points in eight adjacent pixel points; the average pixel value of the zero pixel points is worked out as a new value, and the zero pixel points are converted into the non-zero pixel points; the steps are repeated to obtain the reconstructed image; and the planar position of the reconstructed image is transformed, the planar images with different depths are reconstructed, and a three-dimensional image of an object is integrated and restored. The method has the advantages of high resolution of the reconstructed image, accurate image and low calculating complexity of reconstruction, and can be used for the fields of three-dimensional image display and three-dimensional television and target tracking display and the like.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to three-dimensional image processing, in particular to a high-resolution reconstruction method of an integrated image, which can be used for three-dimensional image display and three-dimensional television of objects. Background technique [0002] In recent years, 3D integrated imaging (Integral Imaging, II) technology has become an important research direction in the field of true 3D stereoscopic display. Compared with helmet 3D display and holographic imaging, this method does not need auxiliary special glasses and coherent light sources, and can provide true 3D real-time stereoscopic images with full parallax, continuous viewpoints, and full colors, and can effectively overcome the problems of traditional multi-view autostereoscopic display. The phenomenon of visual fatigue caused by the mismatch between vergence and focus adjustment range. These advantages make it have ...
