二自由度云台实现人脸追踪。 首先是使用一款名字叫做IP摄像头的APP 采集手机摄像头的图像，在手机上建立一个视频流服务器。在局域网下，PC通过IP还有端口号获取图像。使用OpenCV的人脸检测的API获取人脸在画面中的位置，根据人脸位置距离画面中心的x轴与y轴的偏移量(offset) ，通过P比例控制(PID控制中最简单的一种)控制二自由度云台上臂与下臂的旋转角度，将角度信息通过串口通信UART发送给ESP32单片机(不限于ESP32，STM32,Arduino都可以)解析执行对应的操作，从而使得人脸尽可能处在画面的正中间。

This application uses AWS managed services to process images from IP cameras (or other sources) with AI and trigger actions.
This Python script monitors an RTSP camera stream for motion detection and sends SMS alerts using Twilio when motion is detected. It uses OpenCV to process the video feed and detect motion in real-time, making it ideal for security and surveillance applications.
