Abstract

The present invention provides a model generation method based on a multi-eye panoramic image, which includes: acquiring a reference image and corresponding multiple source images; calculating the image correction rotation matrix of the source image and the reference image; extracting the reference image features of the reference image and the source The source image feature of the image, and calculate the cost body of the reference image and the source image based on the reference image feature and the source image feature; obtain the corrected cost body of the source image and the reference image; correct the cost of multiple source images corresponding to the reference image The final cost volume is obtained by fusion operation; based on the final cost volume, calculate the phase difference distribution estimation of the reference image at the set resolution, and calculate the estimated phase difference at the set resolution; for the reference image at each layer resolution The estimated phase difference is fused to obtain the final phase difference of the reference image; the depth map of the reference image is generated based on the final phase difference of the reference image, and the corresponding stereoscopic vision model is constructed according to the depth map.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for generating a model based on a multi-eye panoramic image. Background technique [0002] Traditional multi-view stereo vision usually uses a monocular camera to sample images at multiple pre-adjusted spatial positions. It is assumed that a picture generated by a certain reference viewing angle is a reference picture, and pictures generated by all viewing angles overlapping with this viewing angle are used as source pictures. The traditional MVS (Mult-view Stereo, multi-view 3D reconstruction) algorithm usually determines the connection between points by finding the matching points of the pixel points / feature points in the reference picture in all source pictures, usually using the difference mark. Based on this relationship, the depth value of each pixel in the reference picture can be further calculated by triangulating the relationship. ...
