Instructions tested with a Raspberry Pi 2 with an 8GB memory card. Probably also works fine on a Raspberry Pi 3.
Download the latest Raspbian Jessie Light image. Earlier versions of Raspbian won't work.
Write it to a memory card using Etcher, put the memory card in the RPi and boot it up.
Log in. Default username / password is pi / raspberry.
Set up Wifi (if you are using Wifi) according to the Raspberry Pi instructions.
Run sudo raspi-config and configure the basics:
- Set up your keyboard layout (It defaults to a British keyboard layout)
- Change default user password
- Enable the Raspberry Pi camera (if you have one attached)
- Configure gpu memory split under 'Advanced'. Set it up '16'.
- Save changes and reboot.
Install required libraries with these commands:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential \
cmake \
gfortran \
git \
wget \
curl \
graphicsmagick \
libgraphicsmagick1-dev \
libatlas-dev \
libavcodec-dev \
libavformat-dev \
libboost-all-dev \
libgtk2.0-dev \
libjpeg-dev \
liblapack-dev \
libswscale-dev \
pkg-config \
python3-dev \
python3-numpy \
python3-pip \
zip
sudo apt-get clean
Install the picamera python library with array support (if you are using a camera):
sudo apt-get install python3-picamera
sudo pip3 install --upgrade picamera[array]
Temporarily enable a larger swap file size (so the dlib compile won't fail due to limited memory):
sudo nano /etc/dphys-swapfile
< change CONF_SWAPSIZE=100 to CONF_SWAPSIZE=1024 and save / exit nano >
sudo /etc/init.d/dphys-swapfile restart
Download and install dlib v19.6:
mkdir -p dlib
git clone -b 'v19.6' --single-branch https://github.com/davisking/dlib.git dlib/
cd ./dlib
sudo python3 setup.py install --compiler-flags "-mfpu=neon"
Install face_recognition:
sudo pip3 install face_recognition
Revert the swap file size change now that dlib is installed:
sudo nano /etc/dphys-swapfile
< change CONF_SWAPSIZE=1024 to CONF_SWAPSIZE=100 and save / exit nano >
sudo /etc/init.d/dphys-swapfile restart
Download the face recognition code examples:
git clone --single-branch https://github.com/ageitgey/face_recognition.git
cd ./face_recognition/examples
python3 facerec_on_raspberry_pi.py
Totally Optional: If you want a desktop GUI, install PIXEL:
sudo apt-get install --no-install-recommends xserver-xorg xinit raspberrypi-ui-mods
