opencv读写中文路径

opencv读写中文路径

传统的读写方法如下:

import cv2
import numpy as np

img = cv2.imread("./001.jpg")
cv2.imshow("sample", img)
cv2.Waitkey(0)

但是上述方法并不支持中文路径，支持中文路径的方法如下
1.

img = cv2.imdecode(np.fromfile("./小花.png", dtype=np.uint8), cv2.IMREAD_COLOR)
cv2.namedWindow("res", cv2.WINDOW_FREERATIO)
cv2.imshow("res", img)
cv2.waitKey(0)

cv2.imencode(".png", img)[1].tofile("./小花.png")

2.借助PIL库读取中文路径，随后转换成opencv格式

from PIL import Image
import numpy as np
import cv2

img = Image.open(img_path)
img = cv2.cvtColor(np.asarray(img),cv2.COLOR_RGB2BGR)
