在opencv python中使用配置JSON文件从ip摄像头加载视频流

pip install opencv-python
pip install json

{
  "camera_url": "http://192.168.0.100:8080/video",
  "username": "admin",
  "password": "password"
}

import cv2
import json

# 读取JSON配置文件
with open('camera_config.json', 'r') as f:
    config = json.load(f)

# 从配置文件中获取摄像头URL、用户名和密码
camera_url = config['camera_url']
username = config['username']
password = config['password']

# 创建IP摄像头对象
cap = cv2.VideoCapture(camera_url)

# 如果需要身份验证，可以设置用户名和密码
if username and password:
    cap.set(cv2.CAP_PROP_USERNAME, username)
    cap.set(cv2.CAP_PROP_PASSWORD, password)

# 循环读取视频帧
while True:
    ret, frame = cap.read()

    if not ret:
        break

    # 在这里可以对视频帧进行处理，如人脸检测、图像识别等

    # 显示视频帧
    cv2.imshow('IP Camera', frame)

    # 按下 'q' 键退出循环
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

# 释放摄像头对象和窗口
cap.release()
cv2.destroyAllWindows()
