操作步骤

1. 码云上下载opencv + opencv_contrib源码(速度比github快)

git clone -b 4.5.1 https://gitee.com/Tengyun_Mo/opencv.git
mv opencv opencv-4.5.1
cd opencv-4.5.1
git clone -b 4.5.1 https://gitee.com/Tengyun_Mo/opencv_contrib.git
mv opencv_contrib opencv_contrib-4.5.1
mkdir build
cd build

3. cmake生成makefile文件

cmake -DCMAKE_BUILD_TYPE=RELEASE     -DCMAKE_INSTALL_PREFIX=/usr/local/opencv-4.5.1     -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib-4.5.1/modules ..     -DWITH_CUDA=1  -DWITH_CUDNN=1 -DWITH_V4L=1 -DOPENCV_DNN_CUDA=1 -D CUDNN_VERSION='8.0.5' -DCUDNN_INCLUDE_DIR='/usr/local/cuda/include/'  -DENABLE_FAST_MATH=1     -DCUDA_FAST_MATH=1     -DWITH_CUBLAS=1    -DCUDA_nppi_LIBRARY=true -DOPENCV_GENERATE_PKGCONFIG=1     -DCUDA_GENERATION=Pascal ..

查看cuda与cudnn是否支持

4. 编译源码

make -j4

5. 安装opencv

sudo make install
