Embodiment Construction

[0035] Embodiments of the present invention will now be described in more detail hereinafter with reference to the accompanying drawings. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.

[0036] The present invention is only aimed at the research of multi-viewpoint image correction of matrix camera array. like figure 2 , the present invention utilizes the traditional camera calibration method (Camera Calibration Toolbox for Matlab) to calibrate the camera to obtain the internal parameters, rotation matrix and translation matrix of each camera of the matrix camera array; utilize the ergodic method to obtain the ideal rotation matrix of the matrix camera array At the same time, the internal matrix of the camera is opti...

Abstract

The invention belongs to the technical field of three-dimensional image processing, and provides an algorithm for correcting a multi-view image obtained through a matrix type camera array. A matrix type camera array multi-view image correction method includes the steps of firstly, calibrating cameras to obtain an internal matrix, a rotating matrix and a horizontal-movement matrix of each camera in the camera array; secondly, calculating an ideal rotating matrix of the matrix type camera array; thirdly, calculating the position of an ideal optical center of each camera in the matrix type camera array; fourthly, calculating an ideal internal matrix of the matrix type camera away; fifthly, calculating a homography matrix, namely, a correction matrix, of the actual multi-view image and the ideal image; sixthly, correcting the multi-view image of the matrix type camera array through a correcting matrix. By means of the matrix type camera array multi-view image correction method, the multi-view image shot by the matrix type camera array can be effectively corrected.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional image correction, and in particular relates to a correction method for multi-viewpoint images captured by a matrix camera array. Background technique [0002] Multi-viewpoint video can provide viewers with multiple viewpoints, so that viewers can freely switch viewpoints and viewing directions within a certain range, bringing viewers a good sense of three-dimensionality and immersion. At present, with the rapid development of free video TV (FTV) and 3DTV, multi-view video production technology has become a new research hotspot. During multi-viewpoint video production, due to reasons such as bracket deformation, differences in the photosensitive elements inside the camera, and manual adjustment errors, there will be vertical parallax between the left and right adjacent viewpoints, and the horizontal parallax will be unequal, and the vertical parallax between the upper and lower adjacent v...
