Jetson TX1 install Opencv3

注意：在編譯的時候會遇到內存空間不足的狀況，能夠插入U盤，將程序拷貝到U盤內編譯，而後安裝到Jetson上。U盤格式化採用NTFS，其餘格式可能沒法識別。

Installation Steps

I’d start by cleaning up older opencv packages and installing necessary dependencies for building opencv.

Regarding the python matplotlibrc modifications below, refer to this StackOverflow thread for more details.

### Remove all old opencv stuffs installed by JetPack (or OpenCV4Tegra) $ sudo apt-get purge libopencv* ### I prefer using newer version of numpy (installed with pip), so ### I'd remove this python-numpy apt package as well $ sudo apt-get purge python-numpy ### Remove other unused apt packages $ sudo apt autoremove ### Upgrade all installed apt packages to the latest versions (optional) $ sudo apt-get update $ sudo apt-get dist-upgrade ### Update gcc apt package to the latest version (highly recommended) $ sudo apt-get install --only-upgrade g++-5 cpp-5 gcc-5 ### Install dependencies based on the Jetson Installing OpenCV Guide $ sudo apt-get install build-essential make cmake cmake-curses-gui \ g++ libavformat-dev libavutil-dev \ libswscale-dev libv4l-dev libeigen3-dev \ libglew-dev libgtk2.0-dev ### Install dependencies for gstreamer stuffs $ sudo apt-get install libdc1394-22-dev libxine2-dev \ libgstreamer1.0-dev \ libgstreamer-plugins-base1.0-dev ### Install additional dependencies according to the pyimageresearch ### article $ sudo apt-get install libjpeg8-dev libjpeg-turbo8-dev libtiff5-dev \ libjasper-dev libpng12-dev libavcodec-dev $ sudo apt-get install libxvidcore-dev libx264-dev libgtk-3-dev \ libatlas-base-dev gfortran $ sudo apt-get install libopenblas-dev liblapack-dev liblapacke-dev ### Install Qt5 dependencies $ sudo apt-get install qt5-default ### Install dependencies for python3 $ sudo apt-get install python3-dev python3-pip python3-tk $ sudo pip3 install numpy $ sudo pip3 install matplotlib ### Modify matplotlibrc (line #41) as 'backend : TkAgg' $ sudo vim /usr/local/lib/python3.5/dist-packages/matplotlib/mpl-data/matplotlibrc ### Also install dependencies for python2 ### Note that I install numpy with pip, so that I'd be using a newer ### version of numpy than the apt-get package $ sudo apt-get install python-dev python-pip python-tk $ sudo pip2 install numpy $ sudo pip2 install matplotlib ### Modify matplotlibrc (line #41) as 'backend : TkAgg' $ sudo vim /usr/local/lib/python2.7/dist-packages/matplotlib/mpl-data/matplotlibrc 

Before downloading and building opencv-3.4.0, I’d first do some modifications according to this post, in order to fix OpenGL related compilation problems . More specifically, I’d modify /usr/local/cuda/include/cuda_gl_interop.h and fix the symbolic link of libGL.so.

$ sudo vim /usr/local/cuda/include/cuda_gl_interop.h $ cd /usr/lib/aarch64-linux-gnu/ $ sudo ln -sf tegra/libGL.so libGL.so 

Here’s how the relevant lines (line #62~68) of cuda_gl_interop.h look like after the modification.

//#if defined(__arm__) || defined(__aarch64__)
//#ifndef GL_VERSION
//#error Please include the appropriate gl headers before including cuda_gl_interop.h
//#endif
//#else
 #include <GL/gl.h>
//#endif

Next, download opencv-3.4.0 source code, cmake and compile. Note that opencv_contrib modules (cnn/dnn stuffs) would cause problem on pycaffe, so after some experiments I decided not to include those modules at all.

### Download opencv-3.4.0 source code $ mkdir -p ~/src $ cd ~/src $ wget https://github.com/opencv/opencv/archive/3.4.0.zip \ -O opencv-3.4.0.zip $ unzip opencv-3.4.0.zip ### Build opencv (CUDA_ARCH_BIN="6.2" for TX2, or "5.3" for TX1) $ cd ~/src/opencv-3.4.0 $ mkdir build $ cd build $ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local \ -D WITH_CUDA=ON -D CUDA_ARCH_BIN="6.2" -D CUDA_ARCH_PTX="" \ -D WITH_CUBLAS=ON -D ENABLE_FAST_MATH=ON -D CUDA_FAST_MATH=ON \ -D ENABLE_NEON=ON -D WITH_LIBV4L=ON -D BUILD_TESTS=OFF \ -D BUILD_PERF_TESTS=OFF -D BUILD_EXAMPLES=OFF \ -D WITH_QT=ON -D WITH_OPENGL=ON .. $ make -j4 $ sudo make install 

Just for reference, here’s the resulting opencv-3.4.0 cmake configuration for my Jetson TX2 system.
