海思3559A上编译OpenCV4.1.0源码操作步骤

it2022-05-05  114

1. 从https://github.com/opencv/opencv/releases 下载opencv源码opencv-4.1.0.zip并解压缩;

2. 修改最顶层的CMakeLists.txt,在第658行加入一条语句如下,fix error: pngstruct.h:30:18: fatal error: zlib.h: No such file or directory #include "zlib.h":

ocv_include_directories(./3rdparty/zlib)

3. 修改3rdparty/libpng/CMakeLists.txt,在文件前加入以下4行语句,fix error: libopencv_imgcodecs.so.4.1.0: undefined reference to png_init_filter_functions_neon等错误:

IF(HISI3559A) SET(ARM 1) SET(ENABLE_NEON 1) ENDIF()

4. 脚本build.sh内容如下:

cmake \ -DCMAKE_BUILD_TYPE=RELEASE \ -DCMAKE_C_COMPILER=/opt/hisi-linux/x86-arm/aarch64-himix100-linux/bin/aarch64-himix100-linux-gcc \ -DCMAKE_CXX_COMPILER=/opt/hisi-linux/x86-arm/aarch64-himix100-linux/bin/aarch64-himix100-linux-g++ \ -DBUILD_SHARED_LIBS=ON \ -DCMAKE_CXX_FLAGS=-fPIC \ -DCMAKE_C_FLAGS=-fPIC \ -DCMAKE_EXE_LINKER_FLAGS=-lpthread -lrt -ldl \ -DENABLE_PIC=ON \ -DWITH_1394=OFF \ -DWITH_ARAVIS=OFF \ -DWITH_ARITH_DEC=ON \ -DWITH_ARITH_ENC=ON \ -DWITH_CLP=OFF \ -DWITH_CUBLAS=OFF \ -DWITH_CUDA=OFF \ -DWITH_CUFFT=OFF \ -DWITH_FFMPEG=ON \ -DWITH_GSTREAMER=ON \ -DWITH_GSTREAMER_0_10=OFF \ -DWITH_HALIDE=OFF \ -DWITH_HPX=OFF \ -DWITH_IMGCODEC_HDR=ON \ -DWITH_IMGCODEC_PXM=ON \ -DWITH_IMGCODEC_SUNRASTER=ON \ -DWITH_INF_ENGINE=OFF \ -DWITH_IPP=OFF \ -DWITH_ITT=OFF \ -DWITH_JASPER=ON \ -DWITH_JPEG=ON \ -DHISI3559A=1 \ -DWITH_PNG=ON \ -DWITH_LAPACK=ON \ -DWITH_LIBREALSENSE=OFF \ -DWITH_NVCUVID=OFF \ -DWITH_OPENCL=OFF \ -DWITH_OPENCLAMDBLAS=OFF \ -DWITH_OPENCLAMDFFT=OFF \ -DWITH_OPENCL_SVM=OFF \ -DWITH_OPENEXR=OFF \ -DWITH_OPENGL=OFF \ -DWITH_OPENMP=OFF \ -DWITH_OPENNNI=OFF \ -DWITH_OPENNNI2=OFF \ -DWITH_OPENVX=OFF \ -DWITH_PROTOBUF=OFF \ -DWITH_PTHREADS_PF=ON \ -DWITH_PVAPI=OFF \ -DWITH_QT=OFF \ -DWITH_QUIRC=OFF \ -DWITH_TBB=OFF \ -DWITH_TIFF=ON \ -DWITH_VULKAN=OFF \ -DWITH_WEBP=ON \ -DWITH_XIMEA=OFF \ -DWITH_GTK=OFF \ -DINSTALL_C_EXAMPLES=ON \ -DINSTALL_PYTHON_EXAMPLES=OFF \ -DBUILD_EXAMPLES=ON \ -DCMAKE_INSTALL_PREFIX=./install \ ..

5. OpenCV根目录下,依次执行如下命令,执行完后会将生成的头文件和动态库存放在build/install目录:

mkdir build cd build cp ../build.sh . ./builld.sh make -j8 make install

6. 将build/bin目录下的example_tutorial_porting_anisotropic_image_segmentation_gapi及动态库拷贝到海思板子上,执行,显示结果一切正常,说明OpenCV编译正常,执行结果如下:

注意:

1. 由于海思板子不支持GTK,所以必须添加-DWITH_GTK=OFF项,所以在海思板子上不支持imshow相关函数;

2. 如想减少编译时间,可不编译examples,将-DINSTALL_C_EXAMPLES和-DBUILD_EXAMPLES由ON调整为OFF。
