Hi3516DV500SVP_NNN添加opencv库记录

默认没有带opencv库，但是实际项目中需要用到opencv库，因此添加一下此库；

1：编译opencv源码，这里具体可以参考

海思Hi3516移植opencv以及错误调试_海思hi3516摄像头开发-CSDN博客

2：在工程的根目录下新建一个3rdparty文件用于存放第三方的库，将编译安装好的库拷贝至3rdparty下并命名为opencv

3：修改src下的CMakeLists.txt，重点可以看一下#opencv的部分，总的说就是查找opencv的库，并链接到库即可

# CMake lowest version requirement cmake_minimum_required(VERSION 3.5.1) # project information project(ACL_CLASSIFICATION_RESNET50) # Compile options add_compile_options(     -std=c++11     -fPIC     -fstack-protector-all     -D_FORTIFY_SOURCE=2 -O2     ) # Specify target generation path set(CMAKE_RUNTIME_OUTPUT_DIRECTORY  "../../../out") set(CMAKE_CXX_FLAGS_DEBUG "-fPIC -O0 -g -Wall") set(CMAKE_CXX_FLAGS_RELEASE "-fPIC -O2 -Wall -s") set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -Wl,-z,relro,-z,now,-z,noexecstack -fPIE -pie") set(CMAKE_SKIP_RPATH TRUE) # Header path include_directories( $ENV{DDK_PATH}/acllib/include/     ../inc/     ../3rdparty/opencv/opencv-3.4.3/lib ) # add host lib path if (target MATCHES "Simulator_Function" OR target MATCHES "Simulator_Instruction" OR target MATCHES "Simulator_Performance")     set(ENV{NPU_HOST_LIB} $ENV{DDK_PATH}/toolkit/tools/sim/lib) else()     set(ENV{NPU_HOST_LIB} $ENV{DDK_PATH}/acllib/lib64/stub) #this case endif() # opencv set(OpenCV_DIR "../3rdparty/opencv/opencv-3.4.3/share/OpenCV") # 查找opencv的path find_package(OpenCV REQUIRED) # 打印opencv的相关信息 message(STATUS "OpenCV library status:") message(STATUS "version: ${OpenCV_VERSION}") message(STATUS "libraries: ${OpenCV_LIBS}") message(STATUS "include path: ${OpenCV_INCLUDE_DIRS}") # set(LIB_PATH $ENV{NPU_HOST_LIB} ) MESSAGE(NPU_HOST_LIB=$ENV{NPU_HOST_LIB}) link_directories(${LIB_PATH}) set(OPENCV_LIB ${OpenCV_DIR}) link_directories(${OPENCV_LIB}) message(${OPENCV_LIB}) FILE(GLOB SAMPLE_SRC_FILE *.cpp) add_executable(main ${SAMPLE_SRC_FILE}) if (target MATCHES "Simulator_Function")     target_link_libraries(main funcsim  ) elseif (target MATCHES "Simulator_Instruction" OR target MATCHES "Simulator_Performance")     target_link_libraries(main instsim  ) else()     target_link_libraries(main svp_acl ss_mpi_sysmem ss_mpi_km pthread securec dl protobuf-c stdc++ ${OpenCV_LIBS}) endif() install(TARGETS main DESTINATION ${CMAKE_RUNTIME_OUTPUT_DIRECTORY})

4：cmake测试

5：代码测试，头文件包含opencv的头文件

至此opencv库移植成功
