ESP32CAM摄像头图像实时传输的配置详解_C/C++

ESP32CAM

前言

配好环境过了好久了，之前一直因为一个库找不到，今天放弃了，用了别的方法

一、环境配置

环境配置看我之前的博客就可以了。

二、视频传输

使用一个usb转ttl连接esp32-cam：（切记一定要将io0接gnd）

ESP32CAM摄像头图像实时传输的配置详解

1.代码

在您的Arduino IDE中，转到文件>示例> ESP32 >相机并打开CameraWebServer示例：。

在上传代码之前，您需要在以下变量修改可以连接的wifi：

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。我使用的是AI-THINKER模型。

因此，请注释所有其他模型，并取消注释该模型：

// Select camera model
//#define CAMERA_MODEL_WROVER_KIT // Has PSRAM
//#define CAMERA_MODEL_ESP_EYE // Has PSRAM
//#define CAMERA_MODEL_M5STACK_PSRAM // Has PSRAM
//#define CAMERA_MODEL_M5STACK_V2_PSRAM // M5Camera version B Has PSRAM
//#define CAMERA_MODEL_M5STACK_WIDE // Has PSRAM
//#define CAMERA_MODEL_M5STACK_ESP32CAM // No PSRAM
#define CAMERA_MODEL_AI_THINKER // Has PSRAM
//#define CAMERA_MODEL_TTGO_T_JOURNAL // No PSRAM

要上传代码，请按照以下步骤操作：

1）转到工具>主板，然后选择AI-Thinker ESP32-CAM。

2）进入工具>端口，选择ESP32连接的COM端口。

3）然后，点击上传按钮上传代码。

不久之后就会上传成功，如果上传不成功或者连接不了，请确认接线是否正确，是否将io0连接gnd
