Abstract
A panoramic image stitching method includes acquiring a plurality of first images, converting camera image plane coordinates of each first image of the plurality of first images into virtual image plane coordinates for generating a second image according a world coordinate system, identifying a plurality of feature points on the second image, calibrating coordinates of the plurality of feature points on the second image, generating a calibrated second image according to calibrated coordinates of the plurality of feature points on the second image, and stitching a plurality of calibrated second images for generating a panoramic image.
