Ubuntu 16.04安装OpenCV 2.x.x和3.x.x教程

Step 1

OpenCV选择Sources版本，下载后是zip格式，解压即可。

Step 2

解决一些依赖关系

sudo apt-get install build-essential

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

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

 

sudo apt-get update

Step 3

将OpenCV3.x.x解压后，进入opencv目录并创建build目录

mkdir build

cd build

Step 4

配置

cmake -DCMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..

make -j2

sudo make install

sudo gedit /etc/ld.so.conf.d/opencv.conf

打开后末尾添加：/usr/local/lib

sudo ldconfig

附：

在pro文件中加入头文件的包含路径和库文件路径

INCLUDEPATH += /usr/local/include \

/usr/local/include/opencv \

/usr/local/include/opencv2

 

LIBS += /usr/local/lib/libopencv_core.so\

/usr/local/lib/libopencv_highgui.so \

/usr/local/lib/libopencv_imgcodecs.so \

/usr/local/lib/libopencv_imgproc.so \

/usr/local/lib/libopencv_ml.so \

/usr/local/lib/libopencv_objdetect.so \

/usr/local/lib/libopencv_photo.so \

/usr/local/lib/libopencv_shape.so \

/usr/local/lib/libopencv_stitching.so \

/usr/local/lib/libopencv_superres.so \

/usr/local/lib/libopencv_video.so \

/usr/local/lib/libopencv_videoio.so \

/usr/local/lib/libopencv_videostab.so \

 

一定一定不要轻易用autoremove！！！

很容易把其他软件依赖的库删掉，导致其他软件无法正常使用。安装其他东西的时候也一定要注意不要同意系统提示的remove！！！
