OpenCV图像的编解码读取

图像编码为bytes

import cv2

# 指定编码为JPEG格式的，要和图片存储的格式一致
img_encode = cv2.imencode('.jpg', img)[1]
data_encode = np.array(img_encode)  
str_encode = data_encode.tostring()

with open('img_encode.txt', 'w') as f:
    f.write(str_encode)

读取bytes文件为图像

import cv2

with open('img_encode.txt', 'r') as f:
    str_encode = f.read()

str_array = np.fromstring(str_encode, np.uint8)
image = cv2.imdecode(str_array, cv2.IMREAD_COLOR)

cv2.imshow("", image)
cv2.waitKey(5000)
