在NVIDIA TX1上編譯OpenCV 3.2.0

   /*============安裝官方給的Opencv依賴包==================*/

•   GCC 4.4.4 or later
•   CMake 2.6 or higher
•   Git
•   GTK+2.x or higher, including headers(libgtk2.0-dev)--->控制opencv gui)
•   pkg-config
•   python 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

 

   /*=============安裝依賴包==================*/

1 $ sudo apt-get install build-essential
2 $ sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
3 $ sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev # 處理圖像所需的包
4 $ sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
5 $ sudo apt-get install libxvidcore-dev libx264-dev # 處理視頻所需的包
6 $ sudo apt-get install libatlas-base-dev gfortran # 優化opencv功能
7 $ sudo apt-get install ffmpeg

** 其餘一些包在以後的cmake的時候缺失的時候會進行安裝，若是安裝失敗能夠手動下載相應的包而後放入提示的目錄下。而cmake下載tar.gz文件的時候可能不支持，須要進行配置，具體操做能夠參考這裏

/*==================下載opencv 3.2.0=======================*/
這裏須要下載opencv和opencv_contrib（後者會在cmake配置的時候用到），這是由於opencv3之後SIFT和SURF之類的屬性被移到了contrib中。

$ wget https://github.com/opencv/opencv/archive/3.2.0.zip 　　　　　　# 從github上直接下載或者clone也可 $ wget https://github.com/opencv/opencv_contrib/archive/3.2.0.zip

/*==================配置編譯opencv=======================*/
將上述opencv包解壓，而後cmake配置屬性
$ cd opencv-3.1.0 
$ mkdir build 
$ cd build 
$ cmake -D CMAKE_BUILD_TYPE=RELEASE 
 -D CMAKE_INSTALL_PREFIX=/home/o2/anaconda2/envs/tensorflow
 -D INSTALL_PYTHON_EXAMPLES=ON
 -D INSTALL_C_EXAMPLES=OFF
 -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.2.0/modules 
 -D PYTHON_EXCUTABLE=/home/o2/anaconda2/envs/tensorflow/bin/python 
 -D WITH_TBB=ON
 -D WITH_V4L=ON 
 -D WITH_QT=ON 
 -D WITH_GTK=ON 
 -D WITH_OPENGL=ON 
 -D BUILD_EXAMPLES=ON .. 

# cmake命令的使用方式：cmake [<some optional parameters>] <path to the OpenCV source directory>。
若是命令報錯的話能夠試着把-D後面的空格去掉在執行一次。 

$ make $ sudo make install

CMAKE_INSTALL_PREFIX：安裝的python目錄前綴，其實就是指定了python模塊的安裝路徑：CMAKE_INSTALL_PREFIX/lib/python2.7/site-packages。獲取該路徑的方式能夠用python -c "import sys; print sys.prefix"
PYTHON_EXCUTABLE：指定python路徑
OPENCV_EXTRA_MODULES_PATH: 指定opencv所需模塊的路徑，就是以前咱們所說的contrib
其餘cmake的具體變量說明能夠看這裏
python -c "import sys; print sys.prefix"

版本。若是正確安裝的話則會輸出3.2.0/*==================完成安裝並測試opencv=======================*/
編譯以後應該會在CMAKE_INSTALL_PREFIX/lib/python2.7/site-packages/目錄下找到cv2.so。打開python console，檢測opencv版本

python -c "import cv2; print cv2.__version__"
