Embodiment

[0019] In this embodiment, a method for correcting a panoramic camera array multi-viewpoint image is proposed, comprising the following steps:

[0020] S1: First arrange multiple panoramic cameras according to the spherical structure, select the spherical center of the spherical structure constructed by multiple panoramic cameras as the coordinate point of the century coordinate system, set the century coordinate system at this coordinate point, and calibrate each Camera, get the internal coordinates K of each camera in the panoramic camera array ijp and the rotation matrix OM and translation matrix T of each camera relative to the reference coordinate point;

[0021] S2: Using the ergodic method, according to the X in the rotation matrix OM of each camera ij , Y ij ,Z ij Respectively represent the camera C ij Relative to the angle formed by the X, Y, and Z directions in the century coordinate system, we can get the optimal rotation array OM by calculation ideal , as an i...

Abstract

The invention discloses a multi-view image correction method for a panorama camera array. The method comprises the following steps of S1, firstly multiple panorama cameras are arranged according to the spherical structure, the center of sphere of the spherical structure which is formed by the multiple panorama cameras is taken as the coordinate point of a century coordinate system which is set at the coordinate point, and each camera is calibrated, so that the internal coordinates Kijp of each camera in the panorama camera array and a rotary matrix OM and a translation matrix T of each camera relative to the reference coordinate point are obtained; and S2, the ergodic method is used, and Xij, Yij and Zij in the rotary matrix OM of each camera represent angles formed by a camera Cij relative to X, Y, Z directions in the century coordinate system. The method has the advantages that the vertical disparity of the multi-view image captured by the panorama camera array can be effectively eliminated so that the corrected multi-viewpoint image can achieve the shooting effect of the ideal horizontal camera array, thereby satisfying the people's viewing needs.

Description

technical field [0001] The invention relates to the technical field of three-dimensional image correction, in particular to a multi-viewpoint image correction method of a panoramic 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 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 viewpoints will be different are equal ...
