python+opencv 电脑调用手机的摄像头
移动端下载一个工具:IP摄像头(app)
Android的下载地址:http://app.mi.com/details?id=com.shenyaocn.android.WebCam
下载安装后,打开app后,点击下方的“打开IP摄像头服务器”(连上wifi,确保电脑与手机处在同一局域网内)。
然后,使用python进行opencv代码调用部分:
import cv2
cv2.namedWindow("camera",1)
#开启ip摄像头
video="http://admin:admin@192.168.1.5:8081/" #此处@后的ipv4 地址需要改为app提供的地址
cap =cv2.VideoCapture(video)
while True:
# Start Camera, while true, camera will run
ret, image_np = cap.read()
# Set height and width of webcam
height = 600
width = 1000
# Set camera resolution and create a break function by pressing 'q'
cv2.imshow('object detection', cv2.resize(image_np, (width, height)))
if cv2.waitKey(25) & 0xFF == ord('q'):
cap.release()
cv2.destroyAllWindows()
break
# Clean up
cap.release()
cv2.destroyAllWindows()
