The application provides a panoramic stereo correction method and system for maintaining binocular parallax. The method comprises: calibration shooting is carried out on a calibration plate by using each pair of stereo cameras to obtain a plurality of pairs of calibration images; homonymous dot pairs are searched in each pair of calibration images and a reference position at which a corresponding second calibration image homonymous dot needs to be adjusted is determined according to a first calibration image homonymous dot; a first panorama and a second panorama are made and winding processing is carried out on the second calibration image homonymous dot position and the reference position based on corresponding image external parameters; and network division is carried out on the second panorama, a new grid angular point position is calculated based on an original grid angular point position, a homonymous dot position in a certain surrounding range, and the reference position, transform relationships of the grids are determines based on the original and new grid angular point positions, and a stereo correction template is obtained by collecting all grid transform relationships. Therefore, a real stereo relationship can be restored correctly; the parallaxes of panoramas of the left eye and the right eye are unified; and a comfortable stereoscopic feeling is realized.
Description
technical field [0001] The present application belongs to the field of panoramic stereo cameras, and in particular relates to a panoramic stereo correction method and system for maintaining binocular parallax. Background technique [0002] At present, the virtual reality shooting equipment on the market can be roughly divided into two types in terms of bracket design: 1. "Ring radiation" scheme: cameras are arranged around a circle to form a "radial shape". Representatives of this type of bracket include Google jump, Surround360, etc.; , "Ring Pairing" scheme: Multiple pairs of stereo cameras are arranged around a circle. Representatives of this type of bracket include Bullet360, NextVR RedDragon 3D, etc. With these two different bracket designs, there are corresponding stereo panoramas (video) Make algorithm flow. The first type of bracket generally uses a set of camera extrinsic parameters (calculated by image algorithms) to calculate the left and right eye panoramas. The...
