以下是一个简单的ESP32-CAM人脸识别示例代码,需要使用到Arduino IDE和ESP32-CAM的相关库:
```
#include "esp_camera.h"
#include <Arduino.h>
#include "camera_index.h"
#include "face_detection.h"
#define ENABLE_IP5306
#include <axp20x.h>
AXP20X_Class axp;
#define PWDN_GPIO_NUM 32
#define RESET_GPIO_NUM -1
#define XCLK_GPIO_NUM 0
#define SIOD_GPIO_NUM 26
#define SIOC_GPIO_NUM 27
#define Y9_GPIO_NUM 35
#define Y8_GPIO_NUM 34
#define Y7_GPIO_NUM 39
#define Y6_GPIO_NUM 36
#define Y5_GPIO_NUM 21
#define Y4_GPIO_NUM 19
#define Y3_GPIO_NUM 18
#define Y2_GPIO_NUM 5
#define VSYNC_GPIO_NUM 25
#define HREF_GPIO_NUM 23
#define PCLK_GPIO_NUM 22
const char* ssid = "YOUR_SSID";
const char* password = "YOUR_PASSWORD";
String message = "";
void setup() {
Serial.begin(115200);
Serial.setDebugOutput(true);
Serial.println();
axp.begin();
axp.setPowerOutPut(AXP192_LDO2, AXP202_ON);
axp.setPowerOutPut(AXP192_LDO3, AXP202_ON);
axp.setDCDC3(false);
axp.setLDO2(true);
axp.setLDO3(true);
axp.setChargeVoltage(AXP192_4_2V);
axp.setChargeCurrent(AXP192_100MA);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println("Connecting to WiFi...");
}
Serial.println("WiFi connected!");
Serial.print("IP address: ");
Serial.println(WiFi.localIP());
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;
config.frame_size = FRAMESIZE_QVGA;
config.jpeg_quality = 12;
config.fb_count = 1;
esp_err_t err = esp_camera_init(&config);
if (err != ESP_OK) {
Serial.printf("Camera init failed with error 0x%x", err);
return;
}
Serial.println("Camera initialized");
delay(1000);
Serial.println("Starting face detection...");
while (true) {
camera_fb_t *fb = esp_camera_fb_get();
if (!fb) {
Serial.println("Failed to capture frame");
continue;
}
face_detection_result_t result = detect_faces(fb->buf, fb->len);
Serial.printf("%d faces detected\n", result.num_faces);
if (result.num_faces > 0) {
message = "Someone is in front of the camera!";
} else {
message = "No one in front of the camera.";
}
esp_camera_fb_return(fb);
delay(1000);
}
}
void loop() {
Serial.println(message);
delay(1000);
}
```
需要注意的是,此代码中的 `detect_faces()` 函数是一个自定义函数,用于执行人脸检测,需要自己实现或使用第三方库。此外,还需要在Arduino IDE中添加ESP32-CAM的相关库,具体方法可以参考ESP32-CAM的官方文档。
