1. A method for fusing images, comprising:
obtaining a long-focal image to be fused and a wide-angle image to be fused;
detecting feature points of the long-focal image and wide-angle image with a same scale, and matching the feature points to obtain matching feature point pairs;
determining a fusion area based on position distributions of the matching feature point pairs;
calculating a mapping matrix from the long-focal image to the wide-angle image at least based on coordinates of the matching feature point pairs in the long-focal image and the wide-angle image; and
resampling the long-focal image based on the mapping matrix and fusing the resampled long-focal image and the wide-angle image in the fusion area to obtain a fused image.
