🔴 Getting Started Guide

1. Remotely access the RPi Desktop using VNC viewer.

Click here, if you do not know how to do it.

Accessing the Rpi through the command prompt for the first time(with Rpi OS installation)

Watch these videos first to know how to install rpi OS and configure the pi to autoconnect to the local wifi network at booting

• Setup Raspberry PI OS with SSH and WIFI the NEW (3/2021) Easy Way ;
• Setup raspberry pi without monitor | Raspberry pi SSH/VNC remote access | Setup VNC server

1. Open command prompt and type following commands.

Input

bimalka98@DEVICE:~$ ssh pi@rpibimalka98

New desktop is rpibimalka98:2 (192.168.x.xxx:x)

2. Now open VNC viewer and type the server's ip produced by the above last command! -> 192.168.x.xxx:x

3. Provide the login credentials when asked - username: pi - password: YOUR_PASSWORD_HERE

4. That's it. You are in!

2. Open the terminal and change the directory to Desktop.
3. Install git on the RPi & Clone this repository.

pi@host:~/Desktop $ sudo apt-get install git
pi@host:~/Desktop $ git clone https://github.com/bimalka98/Computer-Vision-with-Raspberry-Pi.git

4. Get into the cloned repository.

pi@host:~/Desktop $ cd Computer-Vision-with-Raspberry-Pi/

5. Give execution permission to the shell script.

pi@host:~/Desktop/Computer-Vision-with-Raspberry-Pi $ chmod +x setup.sh

6. Run the shell script and wait until it finishes its job.

pi@host:~/Desktop/Computer-Vision-with-Raspberry-Pi $ ./setup.sh

7. Connect a USB camera/ RPi camera to the RPi.
8. Change directory to /Application/bin/.

pi@host:~/Desktop/Computer-Vision-with-Raspberry-Pi $ cd Application/bin/

9. Run the executable, and check whether it really detects faces.

pi@host:~/Desktop/Computer-Vision-with-Raspberry-Pi/Application/bin $ ./face_detection
