Method for generating integrated three-dimensional imaging element images on basis of central projection

Abstract

The invention discloses a method for generating integrated three-dimensional imaging element images on the basis of central projection. Firstly, a three-dimensional scene is established by using a computer, and a database corresponding to coordinates and information of the three-dimensional scene is obtained; virtual micro lens optical parameters are set to accord with optical parameters of a true micro lens, and are displayed in an optical system of an integrated three-dimensional imaging system; all the coordinates of the three-dimensional scene are converted into world coordinates from local coordinates; the coordinates of viewpoints are determined according to the position of a virtual micro lens camera and the position of a space scene; a virtual 3D target is converted into 2D images according to different viewpoints, and the element images are generated according to the coordinates of the viewpoints. According to the method for generating the integrated three-dimensional imaging element images on the basis of the central projection, the technology of geometric projection and mapping is adopted, virtual micro lens array element images are formed through the computer, the obtained element images have the advantages of being wider in view angle range, higher in resolution and larger in field depth, interference among element image arrays obtained on the basis of micro lens arrays is eliminated, and clear integrated three-dimensional images are reconfigured.

Description

technical field [0001] The invention belongs to the technical field of integrated (stereoscopic) imaging, and in particular relates to a method for generating images of integrated stereoscopic imaging elements based on central projection. Background technique [0002] Integrated (stereoscopic) imaging technology (Integral Imaging, referred to as II, also translated as three-dimensional panoramic imaging technology), is an image technology that records and displays 3D spatial scene information through a microlens array. The outstanding feature of the integrated (stereoscopic) imaging technology is (1) the real stereoscopic image is reproduced in space, and the correct display ratio is preserved. No observation equipment is required, and it is not limited by the viewing distance of the observer. (2) The observer is provided with real stereoscopic images of continuous viewpoints, which overcomes the problem of eye concentration and adaptive adjustment conflicts. (3) It is a p...

Problems solved by technology

[0005] The purpose of the embodiments of the present invention is to provide a method for generating images of integrated stereoscopic imaging elements based on central projection, aiming at solving the problem that current integrated stereoscopic imaging acquisition systems usually use optical microlens arrays to acquire images of three-dimensional scenes. Diffraction of light causes the boundary of each element image to be blurred, and there is interference, which leads to the problems of poor contrast and small viewing angle of the integrated stereoscopic image
