Problems solved by technology

In the real camera array shooting of traditional integrated imaging, due to the difficulty of precise control of the spatial position of the camera and the direction of the optical axis and the influence of lens distortion, the camera array must be calibrated first, and the number of cameras used in the camera array is huge, so generating a micro-image array will consume a lot of It is difficult to meet the real-time dynamic display requirements of integrated imaging in real scenes, which greatly limits the application of integrated imaging technology.

Abstract

The invention discloses a remapping-based integral imaging micro-image array rapid generation method. The remapping-based integral imaging micro-image array rapid generation method includes two steps: calculation of a mapping matrix, and acquisition of remapping of a parallax image by means of a camera array. The remapping-based integral imaging micro-image array rapid generation method utilizes a chequer scaling board to calculate and store a mapping matrix, enables a parallax image taken by a camera array to directly generate a micro-image array through remapping, and simplifies three processes, monocular correction of the camera, multi-view calibration and image combination of micro-image array, into one process which is suitable for GPU parallel processing at the same time, so that the generation speed of the micro-image array is accelerated and generation of the micro-image array is easy for implementation.

Description

technical field [0001] The invention relates to image processing technology and integrated imaging technology, in particular to a method for rapidly generating an integrated imaging micro-image array based on remapping. Background technique [0002] Integrated imaging is a naked-eye 3D technology, which includes two processes of shooting and displaying. When shooting, the camera array is used to obtain information from different angles of the three-dimensional scene to generate a micro-image array; when displaying, the micro-image array is passed through the corresponding micro-lens array, and the three-dimensional scene is reconstructed in the viewing space according to the principle of reversible optical path. There are two methods of computer virtual camera array shooting and real camera array shooting in the shooting process. In the real camera array shooting of traditional integrated imaging, due to the difficulty of precise control of the spatial position of the camer...
