Problems solved by technology
However, this solution requires translation and cropping of the parallax image, resulting in black border areas in the adjusted parallax image
As the distance between the target focal plane and the original focal plane increases, the black edge problem becomes more serious, which greatly affects the reconstruction effect of the 3D scene

The invention puts forward an elimination method for an integrated imaging three-dimensional refocusing reproduction image black edge. The method comprises the following three steps that: calculatinga camera array calibration parameter, correcting a shot parallax image and carrying out the refocusing reproduction of a three-dimensional scene. By use of the method, the camera array calibration parameter corresponding to a target focusing plane is calculated to construct a parallax image correction algorithm, and the black edge free correction parallax image corresponding to the target focusingplane is obtained so as to realize the high-quality integrated imaging three-dimensional refocusing reproduction. Meanwhile, the method has the advantages of being simple in calibration and easy in implementation.
Description
1. Technical field [0001] The invention relates to an integrated imaging technology, in particular to a method for eliminating black borders of an integrated imaging three-dimensional refocusing reproduced image. 2. Background technology [0002] Integrated imaging is a naked-eye three-dimensional technology, which is divided into two processes: recording and reproduction. During the recording process, the camera array is used to shoot the 3D scene, the parallax information of the scene is recorded, and the depth plane position of the recording center is determined by camera calibration. During the reproduction process, the obtained parallax information is synthesized into a micro-image array, and the corresponding micro-lens array in front is used for imaging to reconstruct a three-dimensional scene in the viewing space. The reproduction central depth plane is the plane on which the micro image array is focused in the imaging space through the corresponding microlens array...
