Abstract
The present invention provides a method and a device for image rectification, which are applied in the field of image processing. The method includes: receiving two images, the two images are images of a target object captured from different viewpoints; performing an epipolar rectification on the two images; rectifying the two images after the epipolar rectification based on the image contents; and splicing the two images after the rectification based on the image contents. The method can rectify the images captured from different viewpoints, thereby ensuring the pixel alignment, and avoiding visual discomfort to the viewer.
