[PYTHON/OPENCV] warpAffine 함수 : 이미지 이동하기

■ warpAffine 함수를 사용해 이미지를 이동하는 방법을 보여준다.

▶ 예제 코드 (PY)


import cv2
import numpy as np

imageNDArray = cv2.imread("source.jpg")

imageHeight, imageWidth = imageNDArray.shape[:2]

matrixNDArray = np.float32([[1, 0, 100], [0, 1, 100]])

translateImageNDArray = cv2.warpAffine(imageNDArray, matrixNDArray, (imageWidth, imageHeight))

cv2.imwrite("target.jpg", translateImageNDArray)

cv2.imshow("translation image", translateImageNDArray)

cv2.waitKey(0)

cv2.destroyAllWindows()
