ESP32CAM摄像头图像实时传输的配置详解

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)
1.代码
在您的Arduino IDE中,转到文件>示例> ESP32 >相机并打开CameraWebServer示例:。
#include "esp_camera.h" #include <WiFi.h> // // WARNING!!! PSRAM IC required for UXGA resolution and high JPEG quality // Ensure ESP32 Wrover Module or other board with PSRAM is selected // Partial images will be transmitted if image exceeds buffer size // // 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 #include "camera_pins.h" const char* ssid = "*********"; const char* password = "*********"; void startCameraServer(); void setup() { Serial.begin(115200); Serial.setDebugOutput(true); Serial.println(); camera_config_t config; config.ledc_channel = LEDC_CHANNEL_0; config.ledc_timer = LEDC_TIMER_0; config.pin_d0 = Y2_GPIO_NUM; config.pin_d1 = Y3_GPIO_NUM; config.pin_d2 = Y4_GPIO_NUM; config.pin_d3 = Y5_GPIO_NUM; config.pin_d4 = Y6_GPIO_NUM; config.pin_d5 = Y7_GPIO_NUM; config.pin_d6 = Y8_GPIO_NUM; config.pin_d7 = Y9_GPIO_NUM; config.pin_xclk = XCLK_GPIO_NUM; config.pin_pclk = PCLK_GPIO_NUM; config.pin_vsync = VSYNC_GPIO_NUM; config.pin_href = HREF_GPIO_NUM; config.pin_sscb_sda = SIOD_GPIO_NUM; config.pin_sscb_scl = SIOC_GPIO_NUM; config.pin_pwdn = PWDN_GPIO_NUM; config.pin_reset = RESET_GPIO_NUM; config.xclk_freq_hz = 20000000; config.pixel_format = PIXFORMAT_JPEG; // if PSRAM IC present, init with UXGA resolution and higher JPEG quality // for larger pre-allocated frame buffer. if(psramFound()){ config.frame_size = FRAMESIZE_UXGA; config.jpeg_quality = 10; config.fb_count = 2; } else { config.frame_size = FRAMESIZE_SVGA; config.jpeg_quality = 12; config.fb_count = 1; } #if defined(CAMERA_MODEL_ESP_EYE) pinMode(13, INPUT_PULLUP); pinMode(14, INPUT_PULLUP); #endif // camera init esp_err_t err = esp_camera_init(&config); if (err != ESP_OK) { Serial.printf("Camera init failed with error 0x%x", err); return; } sensor_t * s = esp_camera_sensor_get(); // initial sensors are flipped vertically and colors are a bit saturated if (s->id.PID == OV3660_PID) { s->set_vflip(s, 1); // flip it back s->set_brightness(s, 1); // up the brightness just a bit s->set_saturation(s, -2); // lower the saturation } // drop down frame size for higher initial frame rate s->set_framesize(s, FRAMESIZE_QVGA); #if defined(CAMERA_MODEL_M5STACK_WIDE) || defined(CAMERA_MODEL_M5STACK_ESP32CAM) s->set_vflip(s, 1); s->set_hmirror(s, 1); #endif WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } 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(10000); }
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
2.获得网址
通过串口可以获得网址,将网址粘贴到浏览器即可,注意一定要和你的电脑在同一局域网下
