python中PIL.Image和OpenCV图像格式相互转换

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()

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()

判断图像数据是否是OpenCV格式
isinstance(img, np.ndarray)
