Abstract
An image processing method include projecting first and second images which are captured by two fisheye lenses onto first and second hemispherical projection models, respectively; determining a set of waiting-for-stitching surface region pairs on the first and second hemispherical projection models; extracting feature points from the two fisheye images and determining feature points matching each other to serving as pixels matching each other; determining a set of surface region pairs including the pixels matching each other on the first and second hemispherical projection models as the set of waiting-for-stitching surface region pairs; generating a customized projection model on the grounds of the set of waiting-for-stitching surface region pairs by letting a spherical distance between vertexes of each pair in the set of waiting-for-stitching surface region pairs be zero; and generating a third image by projecting the first and second images onto the customized projection model.
