OpenCV从入门到精通——透视变换

透视变换

• 把喜欢的物品拉倒面前来。
• 透视变换

import cv2
import numpy as np
img = cv2.imread("./images/2.jpg")

pts1 = np.float32([[25,30],[179,25],[12,188],[189,190]])
pts2 = np.float32([[0,0],[200,0],[0,200],[200,200]])


M = cv2.getPerspectiveTransform(pts1,pts2)
dst = cv2.warpPerspective(img,M,img.shape[:-1])

cv2.imshow("src",img)
cv2.imshow("dst",dst)
cv2.waitKey(0)
