Check whether the program runs normally
In the main function, change to the corresponding ai mode.
You can modify the WiFi name and password you want to connect to, as well as the name of the hotspot in the esp32_wifi.c file
Download the program of this project to the mspm0 board
Open the serial port assistant on the computer, open the computer to detect the serial port of mspm0, as shown below
After pressing the reset button of mspm0, the serial port assistant will print out the corresponding information
Open the camera and connect to the hotspot released by esp32 (you can also log in directly using sta_ip)
Then enter http://192.168.4.1:81/stream through the browser This access camera screen
Identify cats and dogs. If the recognition is successful, the current center coordinates will be printed out, and the cat image will be placed in front of the previous screen.
At the same time, the terminal will print out the current coordinates and the selected area
Face recognition mode
When switching to face recognition mode,
Download the program of this project to the mspm0 board, open the serial port assistant on the computer, and detect the serial port of mspm0 on the computer, as shown below
After pressing the reset button of mspm0, the serial port assistant will print out the corresponding information
Recognize the face. When you see a face, press the key button to record the face
The following picture appears, which means the recording is successful, and the face 1 is recorded
At this time, you can press and hold the button for two seconds, then release it and press the button again to recognize the current face
At the same time, the terminal will print out the current center coordinates and the recognized face.
Color detection mode
When switching to color detection mode,
Download the program of this project to the mspm0 board and open the serial port assistant on the computer , open the computer and detect the serial port of mspm0, as shown below
After pressing the reset button of mspm0, the serial port assistant will print out the corresponding information
Identify the color. Press the button and a box will appear. You can use this box to select the color you want to use.
Press and hold the button for two seconds, release it and press it again to identify the currently selected color, and a red frame will appear.
At the same time, the terminal will print out the current center coordinates.
QR code detection
When switching to QR code mode,
Download the program of this project to the mspm0 board, open the serial port assistant on the computer, and detect the serial port of mspm0 on the computer, as shown below
After pressing the reset button of mspm0, the serial port assistant will print out the corresponding information
Use the WeChat applet on your mobile phone to search for the QR code generator. A QR code will be generated for the corresponding text and saved to the album. The following is the identification of the QR code.
At the same time, the terminal will print out the recognized text.
