Code sample
import cv2
import numpy as np
image = cv2.imread("opencv-image.png")
height, width = image.shape[:2]
# Three points in the original image
point1 = np.float32([[10.10], [15.20], [50.50]])
The three points of # point1 are converted to correspond to the three points on the resulting image
point2 = np.float32([[8.11], [14.19], [53.47]])
M = cv2.getAffineTransform(point1, point2)
print(M)
dst = cv2.warpAffine(image, M, (width, height))
cv2.imshow("image", image)
cv2.imshow("dst", dst)
cv2.waitKey(0)
cv2.destroyAllWindows()

Python is open source, cross-platform, interpretive, interactive, and worth learning. Python’s design philosophy: elegant, unambiguous, simple. Advocate one way, preferably only one way to do one thing. Code should be written in accordance with specifications to facilitate communication and understanding. Every language has its own unique ideas. Beginners need to change their thinking, practice and accumulate.
