Abstract

The invention discloses a light field image angle reconstruction method, which includes the following steps: (1) converting a low-angle resolution light field image from RGB space to YUV space, and extracting Y channel information; (2) obtaining through a feature fusion reconstruction network Coarse reconstructed light field image Y channel information; (3) Obtain the fused reconstructed light field image Y channel information through the spatial angle feature fusion network; (4) Obtain fine reconstructed light field image Y channel information through the detail fusion repair network; (5) Add the results of steps (3) and (4) to obtain the Y channel information of the final reconstructed light field image; perform bilinear upsampling on the U and V channels of the low angular resolution light field image to obtain the reconstructed light field images U and V V channel information; (6) Convert the obtained Y, U, V channel information to RGB space to obtain an RGB image of the final reconstructed light field image. The present invention can obtain high-quality reconstructed light field images and meet the real-time requirements of various applications such as depth extraction and three-dimensional reconstruction.

Description

technical field [0001] The invention belongs to the technical field of image processing, and more specifically, relates to a method for reconstructing the angle of a light field image. Background technique [0002] Light field imaging can record 3D scene information from multiple angles. Light field images with high angular resolution are widely used in virtual reality, three-dimensional stereo, biomedical detection and other fields. However, due to the limitation of hardware conditions, it is expensive to obtain densely sampled light fields with high angular resolution, which has become the main bottleneck restricting the development of light field imaging technology. Therefore, the reconstruction of high-angle-resolution light-field images from low-angle-resolution light-field images has important theoretical significance and practical application value. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to reconstruct a li...
