基于esp32的摄像头采集图像代码

ESP32 camera sdcard

Camera with Web Server
Preparation
To run this example, you need the following components:

An ESP32 Module: Either ESP32-WROVER-KIT or ESP-EYE, which we highly recommend for beginners, is used in this example.
A Camera Module: Either OV2640 or OV3660 or OV5640 image sensor, which we highly recommend for beginners, is used in this example.
Quick Start
After you've completed the hardware settings, please follow the steps below:

Connect the camera to ESP32 module. For connection pins, please see here
Configure the example through idf.py menuconfig;
Build And Flash the application to ESP32;
Open Your Browser and point it to http://[ip-of-esp32]/;
To Get Image press Get Still or Start Stream;
Use The Options to enable/disable Face Detection, Face Recognition and more;
View The Stream in a player like VLC: Open Network http://[ip-of-esp32]:81/stream;
