Debian搭建OpenCV

Debian 搭建 OpenCV一、安装配置环境编译
$ sudo apt-get install build-essential
所依赖的库
$ sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
可选择安装的库
$ sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff5-dev libdc1394-22-dev
运行时要安装的库
$ sudo apt-get install libgtk2.0-dev pkg-config二、下载OpenCV源码
$ git clone https://github.com/opencv/opencv.git $ cd opencv/
$ git checkout 3.2.0
使用额外的模块
$ git clone https://github.com/opencv/opencv_contrib.git $ cd opencv_contrib/
$ git checkout 3.2.0
注意:
如果到网页下载，可能目录名不一样。cmake配置时要注意目录名就可以了。
三、编译OpenCV(参考链接
https://docs.opencv.org/master/d7/d9f/tutorial_linux_install.html)
$ cd opencv/
$ export PY_NAME=$(python -c 'from sys import version_info as v; print("python%d.%d" % v[:2])')
$ export PY_NUMPY_DIR=$(python -c 'import os.path, numpy.core; print(os.path.dirname(numpy.core.__file__))')
$cmake -DCMAKE_BUILD_TYPE=RELEASE \
-DCMAKE_INSTALL_PREFIX=/usr/local \
-DPYTHON2_EXECUTABLE=$(which python) \ -DPYTHON_INCLUDE_DIR=/usr/include/$PY_NAME \ -DPYTHON_INCLUDE_DIR2=/usr/include/aarch64-linux-gnu/$PY_NAME \ -DPYTHON_LIBRARY=/usr/lib/aarch64-linux-gnu/lib$PY_NAME.so \ -DPYTHON2_NUMPY_INCLUDE_DIRS=/usr/lib/$PY_NAME/dist-packages/numpy/core/include/ \ - DBUILD_DOCS=OFF \ -DBUILD_EXAMPLES=OFF \ -DBUILD_TESTS=OFF \ -DBUILD_PERF_TESTS=OFF \
-DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules \
$ sudo make
$ sudo make install
注意:
第一次执行cmake时可能会配置失败，再执行一次cmake就可以了。cmake会检测或下载相关的包，网络什么都会影响cmake。
执行make编译OpenCV源码时会报"Python.h"头文件找不着，Python.h头文件所在的路径/usr/include/python2.7/Python.h,修改OpenCV的源文件包含Python.h前加上python2.7/，要修改好几处。直接把Python.h拷贝到/usr/include/就可以了。
四、运行Demo
修改canny.py的权限，然后执行./canny.py注意:
运行Demo时会出现出错，要安装apt-get install libgtk2.0-dev pkg-config
