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。
MicroPython ESP32 从入门到差不多系列课程, 1Z实验室出品
1ZLab在准备挑选合适的小车来研发计算机视觉的教程时候 , 发现习惯了Python语法的我们, 在市面上找不到合适小车, 后来我们选了ESP32作为小车的控制主板, 可以使用Python对其进行交互式编程, 极大的提升了开发效率.
