Low-complexity panoramic image and video stitching method

A low-complexity panoramic image and video stitching method comprising steps of:

• providing a first image/video, a second image/video, and a third image, the first image/video being taken at a middle view angle and having a plurality of first features and a plurality of first coordinates;
• the first features corresponding to the first coordinates one on one, the second image/video being taken at a left view angle and having a plurality of second features and a plurality of second coordinates, the second features corresponding to the second coordinates one on one, the third image/video being taken at a right view angle and having a plurality of third features and a plurality of third coordinates, the third features corresponding to the third coordinates one on one;
• carrying out an image/video alignment comprising sub-steps of finding a plurality of common features, each of which is what at least one of the second features is identical to at least one of the first features and what at least one of the third feature is identical to at least one of the second features, and aligning the first, second, and third images/videos according to the common features synchronously;
• carrying out an image/video projection and warping comprising sub-steps of freezing the first coordinates and converting the second and third coordinates belonging to the common features to make the first, second, and third coordinates of the common features correspond to each other, and then stitching the first, second, and third images/videos via the mutually corresponsive first, second, and third coordinates;
• carrying out an image/video repairing and blending for compensating chromatic aberrations of seams between the first, second, and third images/videos;
• and
• outputting the stitched first, second, and third images/videos.
