1.软件版本及下载地址: Opencv3.1.0 http://opencv.org/downloads.html opencv_contrib http://www.cnblogs.com/Geo-fortune/p/4822997.html QT 5.1.0 https://download.qt.io/archive/qt/5.1/5.1.0/ Cmake2.4.5 https://cmake.org/download/ 或者直接在这个百度云盘下载 http://pan.baidu.com/s/1c1FMMbQ 这个云盘里面不包括QT安装包 2. Opencv3.1.0直接解压安装 QT5.1.0直接解压安装 Cmake直接解压即可 Opencv_contrib解压即可 注意:以上所有的文件文件路径都都不能有空格 我的文件夹结构
Cmake文件夹中存放cmake文件 Opencv文件夹存放opencv文件 opencvBinary 存放opencv和opencvContrib编译后的二进制文件 opencvContrib存放opencvContrib文件 QT存放QT解压安装后的文件 3.检查文件的完整性 (1)检查opencv/source是否是以下的内容，下载的opencv可能会缺少一些文件 (2)检查opencv/source/3rdparty
看一下是否存在libwebp文件夹 4. 设置环境变量 将 D:\QTINSTALL\QT\Tools\mingw48_32\bin; D:\QTINSTALL\cmake\bin; D:\QTINSTALL\QT\5.1.0\mingw48_32\bin; 这三个路径添加到环境变量中 5. 改变.cmake文件 将 D:\QTINSTALL\opencv\sources\cmake文件下的OpenCVCompilerOptions.cmake打开， 找到 add_extra_compiler_option(-Werror=non-virtual-dtor) 将其变为 # add_extra_compiler_option(-Werror=non-virtual-dtor) 6. 打开cmke/bin/cmake-gui,设置源文件目录和目标文件目录 (1)源文件目录必须为包含CmakeLists.txt文件的opencv目录 我的源文件目录为: D:\QTINSTALL\opencv\sources (2)目标文件目录可以自行设置，用于保存cmake编译opencv后的二进制代码,我设置的目录为D:\QTINSTALL\opencvBinary
7.点击configure，出现如下界面
编译器选择Specify native compilers，点击next C编译器选择 D:/QTINSTALL/QT/Tools/mingw48_32/bin/gcc.exe C++编译器选择 D:/QTINSTALL/QT/Tools/mingw48_32/bin/g++.exe 点击next
勾选Grouped，在ungrouped Entntries中设置下面几个文件目录 设置为如图所示的文件路径 在Ungrouped Entries下找到Qt5Concurrent_DIR，Qt5Core_DIR，Qt5Gui_DIR，Qt5Test_DIR，Qt5Widgets_DIR，Qt5OpenGL_DIR，它们的Value分别填写为： d:/opencv/Qt/Qt5.5.0/5.5/mingw482_32/lib/cmake/Qt5Concurrent d:/opencv/Qt/Qt5.5.0/5.5/mingw482_32/lib/cmake/Qt5Core d:/opencv/Qt/Qt5.5.0/5.5/mingw482_32/lib/cmake/Qt5Gui d:/opencv/Qt/Qt5.5.0/5.5/mingw482_32/lib/cmake/Qt5Test d:/opencv/Qt/Qt5.5.0/5.5/mingw482_32/lib/cmake/Qt5Widgets d:/opencv/Qt/Qt5.5.0/5.5/mingw482_32/lib/cmake/Qt5OpenGL 点击configure,出现如下界面
勾选WITH_QT WITH_OPENGL WITH_PNG 去掉WITH_CUDA 在 这一栏中添加opencv_contrib的文件位置 如下 点击configure，出现如下提示 9.出现Configuring done 说明暂时没有问题， 单击register按钮,registering done后 关闭cmake软件
9 在cmake设置的目标文件夹中的空闲位置，例如我的位置是 按住shift+右键单击，显示一个 打开命令行 ，打开后 ，执行mingw-32命令，如下图所示 此时，需要关闭杀毒软件以及其他防卫软件 此过程大约需要30分钟左右
10.执行mingw32-make install 大约需要两三分钟
11.进一步配置环境变量 将D:\QTINSTALL\opencvBinary文件夹里面的文件只留下bin和lib文件夹，其余文件都删除 将D:\QTINSTALL\opencv\build文件夹下的include文件夹拷贝到D:\QTINSTALL\opencvBinary\文件夹下面，得到如下目录结构 再将bin目录即D:\QTINSTALL\opencvBinary\bin 添加到环境变量中 12. 新建QT文件，在.pro文件最后面加下面几行代码进行配置
INCLUDEPATH+=D:\InstallOpencv\opencvBinary\include\opencv\ D:\InstallOpencv\opencvBinary\include\opencv2\ D:\InstallOpencv\opencvBinary\include
LIBS+= D:\InstallOpencv\opencvBinary\lib\libopencv_bgsegm310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_bioinspired310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_calib3d310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_ccalib310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_core310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_cvv310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_datasets310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_dnn310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_dpm310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_face310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_features2d310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_flann310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_fuzzy310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_highgui310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_imgcodecs310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_imgproc310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_line_descriptor310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_ml310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_objdetect310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_phase_unwrapping310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_photo310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_plot310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_reg310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_rgbd310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_saliency310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_shape310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_stereo310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_stitching310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_structured_light310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_superres310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_surface_matching310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_text310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_tracking310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_video310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_videoio310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_videostab310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_xfeatures2d310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_xobjdetect310.dll.a\ D:\InstallOpencv\opencvBinary\lib\libopencv_xphoto310.dll.a 13.完成全部安装
在安装过程中会出现的问题 1. CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool. 原因: 没有c和C++的编译工具。 (1)这是由于QT Creator中没有MinGW编译器，需要下载MinGW编译器，再按照步骤http://wenku.baidu.com/view/602cad4cb7360b4c2f3f6429.html 将MinGW编译器整合到QT Creator中 (2)或者没有将bin文件夹加入到环境变量中 按照上面安装步骤所写的第四步进行即可 2. 查看D:/QTINSTALL/opencvBinary/CMakeFiles/CMakeOutput.log “E:/C++” “MATCHES” “^E:/C++/Opencv 3.0/opencv/sources” “OR” “E:/C++” “MATCHES” “^E:/C++”
Regular expression “^E:/C++/Opencv 3.0/opencv/sources” cannot compile Call Stack (most recent call first): CMakeLists.txt:354 (ocv_include_directories) 这个解释是说cmake的安装包里面有空格或者有加号 寻求网上的原因: http://www.cnblogs.com/sn-dnv-aps/p/4561939.html 做出如下变化 修改 opencv/sources/CMakeLists.txt 行数： 174 OCV_OPTION(WITH_IPP …..) 将ON 修改为OFF 行数： 179 OCV_OPTION(WITH_OPENEL ….) 将OFF 修改为ON 行数： 185 OCV_OPTION(WITH_QT ….) 将 OFF 修改为 ON 3. 下载opencv_ffmpeg.dll出现问题 这是由于国内的网络问题使得opencv_ffmped.dll不能下载完成 解决办法: 下载Opencv_ffmpeg.dll http://download.csdn.net/download/kelvin_yan/9710789 下载文件，替换到opencv/3rdparty/ffmepg文件夹下面 4.下载protobuf-cpp-3.1.0.tar.gz出现问题 解决方案 下载protobuf-cpp-3.1.0 http://download.csdn.net/download/lql0716/9738154 将文件放在D:\QTINSTALL\opencvContrib\modules\dnn.download\bd5e3eed635a8d32e2b99658633815ef\v3.1.0 注意:在出现错误提示后，不能清除cmake的缓存，或者关闭cmake,只能点击cmake界面的stop按钮,将
文件直接替换，注意:不能解压！ 5. 出现 ocv_add_testdata 解决方案 打开D:\QTINSTALL\opencvContrib\modules\text文件夹下的文件CMakeLists.txt，将最后三行进行注释，注释为如下形式 6.提示:下载vgg_generated_*.i出现问题 原因:网络问题 解决方案 在http://answers.opencv.org/question/113942/cmake-failing-with-hash-mismatch/上所提到的链接上下载所需的文件， 将文件将文件vgg_generated_*.i替换到D:\QTINSTALL\opencvContrib\modules\xfeatures2d\cmake.download\151805e03568c9f490a5e3a872777b75 文件夹下的文件 8. 这种use –Wno-dev warning可以忽略 9.在cmd中执行mingw32-make出现问题的时候，需要查看提示，根据提示删除不需要的opencv-contrib文件夹 https://github.com/opencv/opencv_contrib/tree/master/modules 可以看到每个模块的具体功能 当我的包中有aruco模块 和ximgproc模块时，会提示错误。此时，需要将opencv-contrib/modules/文件中发生错误的模块删除，用cmake重新编译，再在cmd中执行mingw32-make
