Abstract

The invention discloses a 3D light field conversion method and device, and the method comprises the steps: obtaining the parameters of an arc-shaped camera array; establishing a camera coordinate system according to the parameters; determining position coordinates of a camera in the camera coordinate system; determining position coordinates of a corresponding off-axis parallel structure virtual camera in the coordinate system according to the position of the camera in the camera coordinate system; connecting the central point of the off-axis parallel structure virtual camera with each pixel point corresponding to the central camera of the arc-shaped camera array, and extending a connecting line to an image plane of the arc-shaped camera array; and assigning a value to a pixel point, corresponding to the coordinate system, of a central camera according to whether the extension line and the image plane have an intersection point or not. According to the conversion method, the camera array of the arc-shaped center camera structure is used for collecting the image of the 3D model or the scene, and the image is converted into the image corresponding to the off-axis camera structure, so that the existing arc-shaped camera structure does not generate trapezoidal distortion.

Description

technical field [0001] The invention relates to the technical field of 3D display, in particular to a method and device for converting a 3D light field. Background technique [0002] A stereo camera is a camera array composed of two or more cameras with the same specifications and parameter settings. When making a stereoscopic imaging data source for a 3D display system, it is necessary to use a camera array to perform multi-directional synchronous rendering or acquisition of a 3D model or real scene, so as to obtain multiple parallax images. [0003] According to the camera array layout, the camera array layout structures mainly include parallel, convergent, off-axis parallel and arc forms. In an integrated imaging 3D display system, an off-axis parallel structure is generally used for rendering in 3D modeling software. However, in most actual 3D modeling acquisition systems, an arc structure is generally adopted. [0004] In the arc structure, the camera array is arrang...
