实验十:摄像头实验
一、实验目的
利用ESP32-CAM开启摄像头,在网站上显示实时图像
二、实验内容
1、配置基本的开发环境
2、烧录代码
3、在网页上显示实时摄像
三、实验设备
1.ESP32-CAM发板
2.杜邦线
四、实验步骤
1) 安装ESP32插件
在Arduino IDE中,转到文件>首选项,然后在附加开发板管理网址上添加:https://dl.espressif.com/dl/package_esp32_index.json
2) 在Arduino IDE中,转到文件 > 示例 > ESP32 > Camera,然后打开CameraWebServer示例。在上传代码前需要先修改成可连接的WiFi名字和密码。
const char* ssid = "REPLACE_WITH_YOUR_SSID";
const char* password = "REPLACE_WITH_YOUR_PASSWORD";
然后,确保选择正确的相机模块。在这种情况下,我们使用AI-THINKER模型。
// Select camera model
//#define CAMERA_MODEL_WROVER_KIT
//#define CAMERA_MODEL_ESP_EYE
//#define CAMERA_MODEL_M5STACK_PSRAM
//#define CAMERA_MODEL_M5STACK_WIDE
#define CAMERA_MODEL_AI_THINKER
3)源代码
#include "esp_camera.h"
#include <WiFi.h>
//
// WARNING!!! Make sure that you have either selected ESP32 Wrover Module,
// or another board which has PSRAM enabled
//
// Select camera model

}
Serial.println("");
Serial.println("WiFi connected");
startCameraServer();
Serial.print("Camera Ready! Use 'http://");
Serial.print(WiFi.localIP());
Serial.println("' to connect");
}
void loop() {
// put your main code here, to run repeatedly:
delay(1);
}
4) 视频显示
在串口显示网址和相关配置
在浏览器上输入相应的网址后,在左下角摁一下Start Stream,会显示摄像头内容
ps:Get Still按键是获取照片,Stop Stram停止视频流,Eroll Face是人脸识别注册
