基于互联网的图片传输非常普遍,最常见的是通过先把图片压缩成jpeg,再通过socket发送到客户端,下面直接上代码。
server
import socket
import cv2
s = socket.socket()
host = socket.gethostname()
port = 12345
s.bind((host, port))
camera = cv2.VideoCapture(0)
if camera.isOpened():
success, frame = camera.read()
s.listen(5)
c, addr = s.accept()
while True:
success, frame = camera.read()
result, img_code = cv2.imencode('.jpg', frame)
buffer = frame.tobytes()
c.send(buffer)
c.close()
client
import socket
import cv2
import numpy as np
s = socket.socket()
host = socket.gethostname()
port = 12345
s.connect((host, port))
while True:
data = s.recv(921600)
buffer = np.frombuffer(data, np.uint8)
frame = buffer.reshape(480, 640, 3)
frame2 = cv2.flip(frame, 1)
cv2.imshow('image', frame2)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cv2.destroyAllWindows()
s.close()
–end
