It’s one line of code: H, __ = cv2.findHomography (srcPoints, dstPoints, cv2.RANSAC, 5 ) Before starting the coding stitching algorithm, we need to swap image inputs. So “img_” will take the right image, and “IMG” will take the left image. So let’s jump into stitching coding:

WebThis is a Python 2 based robust homography estimation that uses RANSAC -- a statistical approach for curbing outliers. In computer vision, a homography is a matrix that maps coordinates from one plane to the same plane that has been rotated or translated or transformed in any other way in space.
