要交叉编译OpenCV,需要先安装交叉编译工具链和对应的交叉编译库,然后配置CMake构建选项进行编译。下面是一些基本步骤:
1. 安装交叉编译工具链,例如arm-linux-gnueabihf-gcc。
2. 下载适用于目标平台的OpenCV源代码。
3. 创建一个build文件夹并进入。
4. 运行cmake命令,指定交叉编译工具链和相关库的路径,例如:
cmake -DCMAKE_TOOLCHAIN_FILE=path/to/toolchain.cmake \
-DWITH_CUDA=OFF \
-DWITH_OPENCL=OFF \
-DWITH_OPENMP=OFF \
-DWITH_TBB=OFF \
-DWITH_IPP=OFF \
-DWITH_1394=OFF \
-DWITH_VTK=OFF \
-DWITH_EIGEN=OFF \
-DWITH_QT=OFF \
-DBUILD_DOCS=OFF \
-DBUILD_EXAMPLES=OFF \
-DBUILD_opencv_apps=OFF \
-DBUILD_opencv_calib3d=ON \
-DBUILD_opencv_core=ON \
-DBUILD_opencv_features2d=ON \
-DBUILD_opencv_flann=ON \
-DBUILD_opencv_highgui=ON \
-DBUILD_opencv_imgcodecs=ON \
-DBUILD_opencv_imgproc=ON \
-DBUILD_opencv_ml=ON \
-DBUILD_opencv_objdetect=ON \
-DBUILD_opencv_photo=ON \
-DBUILD_opencv_python2=OFF \
-DBUILD_opencv_python3=OFF \
-DBUILD_opencv_shape=ON \
-DBUILD_opencv_stitching=ON \
-DBUILD_opencv_superres=ON \
-DBUILD_opencv_video=ON \
-DBUILD_opencv_videoio=ON \
-DBUILD_opencv_videostab=ON \
-DCMAKE_BUILD_TYPE=Release \
path/to/opencv/source
5. 运行make命令进行编译,例如:make -j4。
