14、zedboard 7020 編譯Opencv3.4+Opencv_contrib3.4

基本問題描述：因爲希望使用opencv 附加庫的DNN 模塊，搞一下深度學習的內容，因爲上一篇博客已經自己製作了一個debain系統在zynq7020上，因此在該系統上編譯opencv3.4 上，編譯過程如下：

1、安裝附加庫

sudo apt-get install build-essential cmake git pkg-config
sudo apt-get install libjpeg8-dev 
sudo apt-get install libtiff5-dev 
sudo apt-get install libjasper-dev
sudo apt-get install libpng12-dev 
sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
sudo apt-get install libgtk2.0-dev
sudo apt-get install python-dev python3-dev
sudo apt-get install python-numpy python3-numpy

2、下載opencv3.4 的源碼和附件庫 （直接git下載即可）

因爲git 之後的opencv 仍然需要安裝下載一些東西，因此我提供一份已經下載之後，存在錯誤修改過之後的源碼

opencv3.4 鏈接：https://pan.baidu.com/s/18rR4GGDvBEFCGpXRdsNmKA 密碼：n0x4

opencv_contribu3.4 鏈接：https://pan.baidu.com/s/1cDv7QenVuj5H9n8kRJq0CQ 密碼：92r3

 

3、 進入目錄進行編譯 編譯產生 python3 的so文件

cmake -D BUILD_opencv_python3=YES -D BUILD_opencv_python2=NO -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_LIBV4L=ON -D WITH_GTK=ON -D PYTHON3_EXECUTABLE=/usr/bin/python3 -D PYTHON_INCLUDE_DIR=/usr/include/python3.5 -D PYTHON_LIBARARY=/usr/lib/python3.5/config-3.5m-arm-linux-gnueabihf/libpython3.5m.so -D PYTHON3_NUMPY_INCLUDE_DIRS=/usr/local/lib/python3.5/dist-packages/numpy/core/include -D ENABLE_PRECOMPILED_HEADERS=ON -D OPENCV_ENABLE_NONFREE=ON -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-3.4.4/modules/ ..

4、編譯成功

make
sudo make install 

5、成功的顯示

debain@debian:~/opencv-3.4.4/build/lib/python3$ ls
cv2.cpython-35m-arm-linux-gnueabihf.so
debain@debian:~/opencv-3.4.4/build/lib/python3$

6、移動文件

debain@debian:~/opencv-3.4.4/build/lib/python3$ sudo cp cv2.cpython-35m-arm-linux-gnueabihf.so /usr/local/lib/python3.5/dist-packages/
debain@debian:~/opencv-3.4.4/build/lib/python3$ sudo ldconfig
debain@debian:~/opencv-3.4.4/build/lib/python3$ python3
Python 3.5.3 (default, Sep 27 2018, 17:25:39) 
[GCC 6.3.0 20170516] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> 

如果你要使用python2 也可以調用opencv cmake命令改成這個即可

 cmake -D BUILD_opencv_python3=NO -D BUILD_opencv_python2=YES -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_LIBV4L=ON -D WITH_GTK=ON -D PYTHON3_EXECUTABLE=/usr/bin/python2 -D PYTHON_INCLUDE_DIR=/usr/include/python2.7 -D PYTHON_LIBARARY=/usr/lib/python2.7/config-arm-linux-gnueabihf/libpython2.7m.so -D PYTHON_NUMPY_INCLUDE_DIRS=/usr/local/lib/python2.7/dist-packages/numpy/core/include -D ENABLE_PRECOMPILED_HEADERS=ON -D OPENCV_ENABLE_NONFREE=ON -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-3.4.4/modules/ ..

其它命令參考類同
