Embodiment Construction

[0033] 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.

[0034] The present invention is only aimed at the research of multi-viewpoint image correction of parallel camera arrays. Such as figure 2 Parallel camera array multi-viewpoint image correction flow chart, the present invention utilizes traditional camera calibration method (CameraCalibrationToolboxforMatlab) to calibrate the camera, obtains the internal parameter, rotation matrix and translation matrix of each camera of parallel camera array; Ideal rotation matrix and translation matrix, and optimize the internal matrix of the came...

Abstract

The invention belongs to the technical field of three-dimensional image processing and provides a correcting method of multi-view-point images obtained by a parallel camera array. The method comprises the steps that cameras are calibrated, and practical inner matrixes, rotating matrixes and horizontal-moving matrixes of the cameras of the camera array are obtained; parallel camera array ideal rotating matrix computing is carried out; computing of camera ideal light center positions of the parallel camera array is carried out; parallel camera array ideal inner matrix computing is carried out; practical multi-view-point image and ideal image homography matrix (correcting matrix) computing is carried out; and a correcting matrix is used for correcting parallel camera array multi-view-point images. According to the method, the multi-view-point images shot by the parallel 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 parallel 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. During multi-viewpoint video production, due to reasons such as bracket deformation, differences in the photosensitive elements inside the camera, and errors in manual adjustment, there will be vertical parallax and unequal horizontal parallax between adjacent viewpoints, which seriously affects the stereoscopic effect synthesized by the backend of the system. Image Quality. Therefore, performing multi-viewpoint image correction is crucial in the process of multi-viewpoint video production. [0003] In ...
