Python OpenCV格式和PIL.Image格式 互转

OpenCV转换成PIL.Image格式：

import cv2  
from PIL import Image  
import numpy  
  
img = cv2.imread("plane.jpg")  
cv2.imshow("OpenCV",img)  
image = Image.fromarray(cv2.cvtColor(img,cv2.COLOR_BGR2RGB))  
image.show()  
cv2.waitKey()

PIL.Image转换成OpenCV格式：

import cv2  
from PIL import Image  
import numpy  
  
image = Image.open("plane.jpg")  
image.show()  
img = cv2.cvtColor(numpy.asarray(image),cv2.COLOR_RGB2BGR)  
cv2.imshow("OpenCV",img)  
cv2.waitKey()
