Ubuntu under Install OpenCV

It is recommended that you do not install more than 3.0 versions, but 2.4.10 does not support GPU, true TM pit Dad, should be able to use the 2.4.12 version. I was cuda8.0+opencv2.4.13.

1. Download the opencv2.4.12 version first

Http://opencv.org/downloads.html

2. Install dependent packages

SudoApt-getInstallLibopencv-devBuild-essentialCheckinstallCMakePkg-configYasmLibtiff4-devLibjpeg-devLibjasper-devLibavcodec-devLibavformat-devLibswscale-devLibdc1394-22-devLibxine-devLibgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev  Python-dev python-numpy libtbb-dev libqt4-dev libgtk2.0-dev Span class= "Hljs-selector-tag" >libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev  Libxvidcore-dev x264 v4l-utils    

3. Build OpenCV

CD OpencvmkdirReleasecdReleasecmake-D cmake_build_type=RELEASE-D cmake_install_prefix=/usr/Local-d with_tbb=on-D BUILD_NEW_ Python_support=on-d with_v4l= On-d install_c_examples=on-D Install_python_examples=on-d BUILD_EXAMPLES=on-d with_qt=on- D with_opengl=on-d enable_fast_math= 1-d cuda_fast_math=1-d with_cublas=1:         

4. Check the CMake output to ensure that Cuda and Cublas options are turned on

--     Use Cuda:                    YES (ver 6.5)--     Use OpenCL:                  YES----   NVIDIA CUDA-- Use CUFFT: YES-- Use CUBLAS: YES-- USE NVCUVID: NO-- NVIDIA GPU arch: 11 12 13 20 21 30 35-- NVIDIA PTX archs: 30-- Use fast math: YES

5, if any, start to install OpenCV

make -j8  //建议多线程编译.单线程超慢sudo make install

6. Configure Environment variables

echo ‘/usr/local/lib‘ | sudo tee -a /etc/ld.so.conf.d/opencv.confsudo ldconfigprintf ‘# OpenCV\nPKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig\nexport PKG_CONFIG_PATH\n‘ >> ~/.bashrcsource ~/.bashrc

If you want to delete OpenCV, you can do it directly under this directory

make uninstall

View OpenCV version

--modversion opencv

For problem solving: The Spyder does not support OPENCV module code hints

1. Locate the module_completion.py file, 2.25 and before the version is located on the Python目录/Lib/site-packages/spyderlib/utils/ path, 2.25 after the version is located Python目录/Lib/site-packages/spyderlib/utils/introspection/ . Add CV and Cv2 to the module_completion.py mods variable on line No. 274 of the file to save the file:

2. After the modification, delete the files in the same directory module_completion.pyc , so that the modified module_completion.py file will take effect.

3. Go to the user directory Users/用户名/.spyder2/db and delete the files in the directory submodules .

4. Restart Spyder,enjoy it.
