Ubuntu配置opencv环境

官网：https://docs.opencv.org/3.4.3/d7/d9f/tutorial_linux_install.html

The following steps have been tested for Ubuntu 10.04 but should work with other distros as well.

Required Packages

GCC 4.4.x or laterCMake 2.8.7 or higherGitGTK+2.x or higher, including headers (libgtk2.0-dev)pkg-configPython 2.6 or later and Numpy 1.5 or later with developer packages (python-dev, python-numpy)ffmpeg or libav development packages: libavcodec-dev, libavformat-dev, libswscale-dev[optional] libtbb2 libtbb-dev[optional] libdc1394 2.x[optional] libjpeg-dev, libpng-dev, libtiff-dev, libjasper-dev, libdc1394-22-dev[optional] CUDA Toolkit 6.5 or higher

The packages can be installed using a terminal and the following commands or by using Synaptic Manager:

[compiler] sudo apt-get install build-essential

[required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

[optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

Getting OpenCV Source Code

You can use the latest stable OpenCV version or you can grab the latest snapshot from our Git repository.

Getting the Latest Stable OpenCV Version

Go to our downloads page.Download the source archive and unpack it.

Getting the Cutting-edge OpenCV from the Git Repository

Launch Git client and clone OpenCV repository. If you need modules from OpenCV contrib repository then clone it as well.

For example

cd ~/<my_working_directory>

git clone https://github.com/opencv/opencv.git

git clone https://github.com/opencv/opencv_contrib.git

Building OpenCV from Source Using CMake

Create a temporary directory, which we denote as <cmake_build_dir>, where you want to put the generated Makefiles, project files as well the object files and output binaries and enter there.

For example

cd ~/opencv

mkdir build

cd build

Configuring. Run cmake [<some optional parameters>] <path to the OpenCV source directory>

For example

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..

or cmake-gui

set full path to OpenCV source code, e.g. /home/user/opencvset full path to <cmake_build_dir>, e.g. /home/user/opencv/buildset optional parametersrun: “Configure”run: “Generate”

Note

Use cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local .. , without spaces after -D if the above example doesn't work.

Description of some parameters build type: CMAKE_BUILD_TYPE=Release\Debugto build with modules from opencv_contrib set OPENCV_EXTRA_MODULES_PATH to <path to opencv_contrib/modules/>set BUILD_DOCS for building documentsset BUILD_EXAMPLES to build all examples[optional] Building python. Set the following python parameters: PYTHON2(3)_EXECUTABLE = <path to python>PYTHON_INCLUDE_DIR = /usr/include/python<version>PYTHON_INCLUDE_DIR2 = /usr/include/x86_64-linux-gnu/python<version>PYTHON_LIBRARY = /usr/lib/x86_64-linux-gnu/libpython<version>.soPYTHON2(3)_NUMPY_INCLUDE_DIRS = /usr/lib/python<version>/dist-packages/numpy/core/include/[optional] Building java. Unset parameter: BUILD_SHARED_LIBSIt is useful also to unset BUILD_EXAMPLES, BUILD_TESTS, BUILD_PERF_TESTS - as they all will be statically linked with OpenCV and can take a lot of memory.

Build. From build directory execute make, it is recommended to do this in several threads

For example

make -j7 # runs 7 jobs in parallel

[optional] Building documents. Enter <cmake_build_dir/doc/> and run make with target "doxygen"

For example

cd ~/opencv/build/doc/

make -j7 doxygen

To install libraries, execute the following command from build directory

sudo make install

[optional] Running tests

 如果提示：error while loading shared libraries: libopencv_highgui.so

执行如下：

$ sudo /bin/bash -c 'echo "/home/fanzong/anaconda2/envs/tensorflow/lib" > /etc/ld.so.conf.d/opencv.conf' $ sudo ldconfig
