opencv保存图片路径包含中文乱码解决方案

# coding: utf-8
import numpy as np
import cv2

img = cv2.imread('1.jpg',1)
cv2.imshow('image', img)

k = cv2.waitKey(0)

if k == 27:
   cv2.destroyAllWindows() 
elif k == ord('s'):
    cv2.imwrite('保存_1.jpg', img)   
    cv2.destroyAllWindows()

按S后图片保存成功，中文乱码如下图：

解决方案：

将cv2.imwrite('保存_1.jpg', img)替换为cv2.imencode('.jpg', img)[1].tofile(filenpath)

完整代码如下：

# coding: utf-8
import numpy as np
import cv2

img = cv2.imread('1.jpg',1)
cv2.imshow('image', img)

k = cv2.waitKey(0)

if k == 27:
   cv2.destroyAllWindows() 
elif k == ord('s'):
    #cv2.imwrite('保存_1.jpg', img)   
    cv2.imencode('.jpg', img)[1].tofile('保存_1.jpg')
    cv2.destroyAllWindows()

效果：
