Actually base-OpenCV has a great function for this: `cv2.findTransformECC()`:
https://learnopencv.com/image-alignment-ecc-in-opencv-c-pyth... It can do dense translation, translation + rotation, Affine, and Homography alignment; I've used it in the past to do sub-pixel Aruco/AprilTag alignment (and I'd probably also use it for astrophotography). |
