How to Install OpenCV (3.3.0) on Jetson TX2

from JK Jung's blog: https://jkjung-avt.github.io/opencv3-on-tx2/

When I started programming with python3 on Jetson TX2, I found that “import cv2” did not work. It appeared that the pre-installed OpenCV4Tegra (2.4.13.1) only provided bindings for python2.7. After some research, I found the recommended solution to this problem was to re-compile OpenCV.

I was kind of reluctant to remove OpenCV4Tegra and re-build OpenCV by myself. But anyway I finally decided to do it. I documented the procedure below.

Prerequisite:

• Complete installation of JetPack-3.1 on the target Jetson TX2.

Reference:

• Installing OpenCV Guide for Jetson TK1
• Ubuntu 16.04: How to install OpenCV

Installation Steps:

Note that opencv_contrib modules (cnn/dnn stuffs) would cause problem on python caffe. After some experiment I decided not to include those modules at all.

### Remove OpenCV4Tegra$ sudo apt-get purge libopencv4tegra-python libopencv4tegra-dev libopencv4tegra$ sudo apt-get purge libopencv4tegra-repo### 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 libglew1.6-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 libtiff5-dev libjasper-dev libpng12-dev libavcodec-dev$ sudo apt-get install libxvidcore-dev libx264-dev libgtk-3-dev libatlas-base-dev gfortran### Install dependencies for python3$ sudo apt-get install python3-dev python3-pip$ sudo pip3 install numpy### 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$ sudo pip install numpy### Download opencv-3.3.0 and opencv_contrib-3.3.0 source code$ mkdir -p ~/src$ cd ~/src$ wget https://github.com/opencv/opencv/archive/3.3.0.zip -O opencv-3.3.0.zip$ unzip opencv-3.3.0.zip### Build opencv (if for TX1, set CUDA_ARCH_BIN="5.3" instead)$ cd opencv-3.3.0$ 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 ..$ make -j4$ sudo make install

Just for reference, here’s the resulting OpenCV 3.3.0 cmake configuration for my Jetson TX2 system.

To verify the installation:

$ ls /usr/local/lib/pyhton3.5/dist-packages/cv2.*cv2.cpython-35m-aarch64-linux-gut.so$ ls /use/local/lib/python2.7/dist-packages/cv2.*cv2.so$ python3 -c 'import cv2; print(cv2.__version__)'3.3.0$ python -c 'import cv2; print(cv2.__version__)'3.3.0

Bonus:

With OpenCV 3.3.0 properly istalled on your Jetson TX2, you should be able to use python code to capture and display live video from either the Jetson onboard camera, a USB webcam or a IP CAM. Just follow along this later post by myself: How to Capture and Display Camera Video with Python on Jetson TX2.
