源码编译OpenCV 启用cuda 加速

系统:ubuntu22.04 x86_64
显卡：nvidia 4070tisuper 16G
NVIDIA-SMI 550.67
Driver Version: 550.67
CUDA Version: 12.4

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

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

检出4.10.0 版本,目前2024年6月5日，最新版本

git checkout 4.10.0

clone opencv_contrib

我这里放在 opencv/modules/opencv_contrib

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

编译cuda支持

指定安装路径 CMAKE_INSTALL_PREFIX
指定opencv_contrib路径 /media/wmx/ws1/software/opencv/modules/opencv_contrib/modules

mkdir build & cd build

cmake -D CMAKE_BUILD_TYPE=RELEASE \
      -D CMAKE_INSTALL_PREFIX=/media/wmx/soft1/software/opencv-4.10 \
      -D OPENCV_GENERATE_PKGCONFIG=YES \
      -D WITH_CUDA=ON \
      -D WITH_CUBLAS=ON \
      -D CUDA_NVCC_FLAGS="-D_FORCE_INLINES" \
      -D BUILD_opencv_cudacodec=OFF \
      -D OPENCV_DNN_CUDA=ON \
      -D OPENCV_EXTRA_MODULES_PATH=/media/wmx/ws1/software/opencv/modules/opencv_contrib/modules \
      ..
      

生成MakeFile
然后编译

make  -j48

安装

make install
