CMAKE-如何将塔库与OpenCV -C 项目联系起来

CMake - How to include and link Pylon library with OpenCV-C++ project

本文关键字：OpenCV 项目 联系 起来 CMAKE-      更新时间：2023-10-16

我正在尝试从与Jetson TX1连接的BASLER摄像机访问图像（Ubuntu 16.04）。我将OpenCV-C++与Pylon库一起使用。我正在尝试使用cmake链接Pylon。我有以下CMakeLists.txt文件：

cmake_minimum_required(VERSION 3.5.1)
project(basler_test)
set(CMAKE_CXX_STANDARD 14)
#set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -Wl, -E")
find_package(OpenCV REQUIRED)
include_directories(/opt/pylon5/include)
link_directories(/opt/pylon5/lib64)
add_executable(basler_test basler_test.cpp)
target_link_libraries(basler_test ${OpenCV_LIBS} /opt/pylon5/include/pylon/PylonIncludes.h)

cmake .命令工作正常，但是当我做make时，它给出：

fatal error: pylon/Platform.h: No such file or directory compilation terminated

我检查了上述文件，并且确实存在于与PylonIncludes.h相同的目录中。因此，我相信此错误是因为在CMakeLists.txt中尚未正确设置某些内容。我没有足够的经验来确定它们的问题。请帮助。

这是源文件的相关部分：basler_test.cpp 

//This is a test program to check the functionality of Basler dart daA2500-14uc Camera.  
#define saveImages 0
#define recordVideo 1
#include <iostream>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/video/video.hpp>
#include <pylon/PylonIncludes.h>
#ifdef PYLON_WIN_BUILD
#include <pylon/PylonGUI.h>
#endif
static const uint32_t c_countOfImagesToGrab = 10;
int main(int argc, char* argv[])
{
         ...................................
         ..................................
}

我想这是包括塔库的最佳方法。

在cmakelists.txt中定义在哪里可以找到塔库，

find_package(Pylon QUIET)
if (NOT ${Pylon_FOUND})
    include("${CMAKE_CURRENT_SOURCE_DIR}/cmake/FindPylon.cmake")
endif()

这里findpylon.cmake可以以这种方式写下

        set(PYLON_ROOT $ENV{PYLON_ROOT})
        if (NOT DEFINED ENV{PYLON_ROOT})
            set(PYLON_ROOT "/opt/pylon5")
        endif()
        set(_PYLON_CONFIG "${PYLON_ROOT}/bin/pylon-config")
        if (EXISTS "${_PYLON_CONFIG}")
            set(Pylon_FOUND TRUE)
            execute_process(COMMAND ${_PYLON_CONFIG} --cflags-only-I OUTPUT_VARIABLE HEADERS_OUT)
            execute_process(COMMAND ${_PYLON_CONFIG} --libs-only-l OUTPUT_VARIABLE LIBS_OUT)
            execute_process(COMMAND ${_PYLON_CONFIG} --libs-only-L OUTPUT_VARIABLE LIBDIRS_OUT)
            string(REPLACE " " ";" HEADERS_OUT "${HEADERS_OUT}")
            string(REPLACE "-I" "" HEADERS_OUT "${HEADERS_OUT}")
            string(REPLACE "n" "" Pylon_INCLUDE_DIRS "${HEADERS_OUT}")
            string(REPLACE " " ";" LIBS_OUT "${LIBS_OUT}")
            string(REPLACE "-l" "" LIBS_OUT "${LIBS_OUT}")
            string(REPLACE "n" "" Pylon_LIBRARIES "${LIBS_OUT}")
            string(REPLACE " " ";" LIBDIRS_OUT "${LIBDIRS_OUT}")
            string(REPLACE "-L" "" LIBDIRS_OUT "${LIBDIRS_OUT}")
            string(REPLACE "n" "" LIBDIRS_OUT "${LIBDIRS_OUT}")
            set(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE)
            foreach (LIBDIR ${LIBDIRS_OUT})
                link_directories(${LIBDIR})
            endforeach()
        else()
            set(Pylon_FOUND FALSE)
        endif()

然后，您可以通过以下方式将塔包括在lib或可执行二进制中的文件，

include_directories(
        #add other includes directories 
        ${Pylon_INCLUDE_DIRS}
)

相同的方式，您可以通过引用以下方式链接塔lib目录：$Pylon_LIBRARIES。希望这可能会有所帮助谁将再次陷入这个问题。

我让相机正常工作。我不得不将/opt/pylon5/lib64作为参数的一些文件添加到target_link_libraries()。我的CMakeLists.txt文件看起来像：

cmake_minimum_required(VERSION 3.5.1)
project(basler_test)
set(CMAKE_CXX_STANDARD 14)
#set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -Wl, -E")
find_package(OpenCV REQUIRED)
include_directories(/opt/pylon5/include)
link_directories(/opt/pylon5/lib64)
add_executable(basler_test basler_test.cpp)
#target_include_directories(basler_test /opt/pylon5/include)
target_link_libraries(basler_test ${OpenCV_LIBS} pylonutility pylonbase GCBase_gcc_v3_0_Basler_pylon_v5_0)
