Install OpenCV versi GPU

Navigasi direktori

cd ~/ext_pkg

Clone repository dari github opencv

git clone https://github.com/opencv/opencv opencv
git clone https://github.com/opencv/opencv_contrib opencv_contrib

Membuat folder build:

cd opencv
mkdir build
cd build

Memasukkan argumen untuk compile: ubah CUDA ARCH BIN sesuai GPU yang dipakai

cmake -D CMAKE_BUILD_TYPE=RELEASE \
	-D CMAKE_INSTALL_PREFIX=/usr/local \
	-D INSTALL_PYTHON_EXAMPLES=ON \
	-D INSTALL_C_EXAMPLES=OFF \
	-D OPENCV_ENABLE_NONFREE=ON \
	-D WITH_CUDA=ON \
	-D WITH_CUDNN=ON \
	-D OPENCV_DNN_CUDA=ON \
	-D ENABLE_FAST_MATH=1 \
	-D CUDA_FAST_MATH=1 \
	-D CUDA_ARCH_BIN=7.5 \
	-D WITH_CUBLAS=1 \
	-D OPENCV_EXTRA_MODULES_PATH=~/ext_pkg/opencv_contrib/modules \
	-D HAVE_opencv_python3=OFF \
	-D PYTHON_EXECUTABLE=/usr/bin/env/python3 \
	-D BUILD_EXAMPLES=ON ..

Compile menggunakan make:

make -j4

(Note: j4 artinya compiler akan menggunakan 4 core cpu) (Note lagi: Selamat menunggu selama 3 jam wkwkwkwk)

Setelah compile selesai, install opencv tersebut:

sudo make install
