🌼 How to install openCV in your RasberryPi

🔥 Make sure there's no opencv file exists in your RasberryPi

1. Check your RasberryPi OS version

$ cat /etc/*release*

2. Update any existing packages

$ sudo apt-get update

3. Install some developer tools

$ sudo apt-get install build-essential cmake pkg-config
$ sudo apt-get install libjpeg-dev libtiff5-dev libjasper-dev libpng12-dev
$ sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
$ sudo apt-get install libxvidcore-dev libx264-dev
$ sudo apt-get install libgtk2.0-dev
$ sudo apt-get install libatlas-base-dev gfortran
$ sudo apt-get install python2.7-dev python3-dev

4. Download the openCV source code

$ cd ~
$ wget -O opencv.zip https://github.com/Itseez/opencv/archive/3.1.0.zip
$ unzip opencv.zip
$ wget -O opencv_contrib.zip https://github.com/Itseez/opencv_contrib/archive/3.1.0.zip
$ unzip opencv_contrib.zip

⚡ I don't know why, but in my RasberryPi, I can get opencv-3.0.0 file when I do unzip opencv.zip
     Make sure the opencv_contrib and opencv file's version are the same
     So I just download the opencv file in window, and I import it by USB.

4. Install pip

$ wget https://bootstrap.pypa.io/get-pip.py
$ sudo python get-pip.py

5. Install numpy

$ pip install numpy

6. Setup build using CMake

$ cd ~/opencv-3.1.0/
$ mkdir build
$ cd build
$ cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local \
    -D INSTALL_PYTHON_EXAMPLES=ON \
    -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.1.0/modules \
    -D BUILD_EXAMPLES=ON ..

7. Build

$ make -j4

⚡ It could take more than 2 hours, so just take a rest.

8. Install openCV

$ sudo make install
$ sudo ldconfig

9. Finish

🌼 Install several Libraries

1. Install dlib prerequisites

$ sudo apt-get update
$ sudo apt-get install build-essential cmake
$ sudo apt-get install libgtk-3-dev
$ sudo apt-get install libboost-all-dev

2. Use pip to install dlib with Python bindings

$ pip install scipy
$ pip install dlib

⚡ It could take more than 2 hours, so just take a rest.

🌼 To run the code

🔥 Make sure haarcascade_frontalface_default.xml/shape_predictor_68_face_landmarks.dat files are in the same directory with thd code

python pi_detect_drowsiness.py --cascade haarcascade_frontalface_default.xml \
	--shape-predictor shape_predictor_68_face_landmarks.dat
