首先输入一个没有旋转的图片,使用python运行代码 [INFO] detected orientation: 0 [INFO] rotate by 0 degrees to correct [INFO] detected script: Latin 0度 然后我们输入一张经过旋转的照片,再次运行代码 [INFO] detected orientation: 90 [INFO] rotate by 270 degrees to correct [INFO] detected script: ...
In this OpenCV tutorial, we will learn how to rotate an image to 90, 180 and 270 degrees using OpenCV Python using cv2.getRotationMatrix2D() and cv2.warpAffine() functions, with an example. OpenCV Python – Rotate Image We can rotate an image using OpenCV to any degree. To rotate an i...

The second argument is the rotation matrix, and the third argument is the size of the output image. For example, let’s rotate the above image to 45 degrees around its center. See the code below. import cv2 import numpy as np image = cv2.imread("cat.jpg") (h, w) = image.shape[...
