Using a combination of an ESP32 and an Orange Pi 5 for face detection would involve a few steps:
Connect the ESP32 to the Orange Pi 5: You will need to connect the ESP32 to the Orange Pi 5 using a serial communication protocol such as UART or I2C. This will allow the Orange Pi 5 to communicate with the ESP32 and send commands to the ESP32 to capture images and perform face detection.
Capture images using the ESP32: The ESP32 has a built-in camera interface that can be used to capture images. You will need to write code to capture images from the ESP32 camera and send the images to the Orange Pi 5 for processing.
Perform face detection on the Orange Pi 5: Once the images have been captured by the ESP32, the Orange Pi 5 can process the images to detect faces. There are several libraries and frameworks available for performing face detection on the Orange Pi 5, such as OpenCV, dlib, and MTCNN.
Send the results back to the ESP32: Once the face detection has been performed on the Orange Pi 5, the results can be sent back to the ESP32. The ESP32 can then use the results to trigger an action, such as sending a notification or controlling a device.
It’s important to keep in mind that the ESP32 and Orange Pi 5 are not designed to work together, so you may need to write your own code to make them communicate with each other. Also, you will need to have a good understanding of programming languages such as Python and C++, as well as experience with computer vision and image processing.
On the ESP32 side;
import serial
ser = serial.Serial('/dev/ttyS0', baudrate=115200)
while True:
data = ser.readline().decode()
print(data)
One the Orange Pi 5 Side;
import serial
ser = serial.Serial('/dev/ttyS0', baudrate=115200)
while True:
data = input("Enter data to send: ")
ser.write(data.encode())
This code opens a serial communication on the Orange Pi 5 using the UART interface and sets the baudrate to 115200. It then waits for the user to input data, encodes it and sends it through the serial port.
This example is a basic one and you will have to modify it to suit your specific use case and requirements. Also, you may need to adjust the UART pins, baudrate and other settings accordingly.
It’s important to keep in mind that this is a general example and it’s recommended to check the documentation of the libraries and the hardware you’re using to make sure the code runs correctly.
