Problems solved by technology

[0005] However, the existing methods generally have the following deficiencies: First, in the process of correction, they only rely on the basic matrix or matching points, while ignoring the information of the scene itself, so that the corrected stereo image pair may satisfy the scan line characteristics, but does not meet viewing requirements
Its shortcomings not only increase the processing steps, but also change the parallax of the image pair during the linear zoom-in process

Abstract

The invention provides a geometrical correction method of binocular stereoscopic video, which comprises the following steps of: obtaining the scene direction information of a stereoscopic video frame pair; carrying out polarline correction on the stereoscopic video frame pair according to the scene direction information to obtain a first correction video frame pair; and carrying out nonlinear transformation on the first correction video frame pair to obtain a final correction video frame pair. The geometrical correction method of binocular stereoscopic video ensures that a corrected image more meets the scene characteristics and the viewing requirement by introducing the scene direction information to carry out polarline correction, makes up the defect that cutting and linear scaling are purely utilized for eliminating a black edge after polarline correction by nonlinear transformation correction and has stronger practicability.

Description

technical field [0001] The present invention relates to the technical field of image and video processing, in particular to a method and system for geometric correction of binocular stereoscopic video. Background technique [0002] A binocular stereo image pair is an image captured by two parallel cameras located at the same height for the same scene. The images of a point in three-dimensional space on two image planes are called corresponding points, and they satisfy the epipolar constraint. For an ideal stereo image pair, there is only horizontal parallax between corresponding points, but no vertical parallax. If such two images are provided to the left and right eyes of the viewer respectively, the brain will extract the depth information of the scene according to the horizontal parallax, so that Create a stereoscopic effect. In actual shooting, due to the problems of convergence, rotation, and different heights in the placement of cameras, ideal stereo image pairs cann...
