Introduction
The main goal of this wiki is to provide a guide for the installation of OpenCV3.3 on the Jetson TX2 board. This guide gives the commands to follow to install opencv and its required packages
Uninstall OpenCV4Tegra
Uninstall OpenCV for Tegra packages, purge local repositories, and update the apt cache using the following commands:
sudo apt-get purge libopencv4tegra-dev libopencv4tegra sudo apt-get purge libopencv4tegra-repo sudo apt-get update
Required Packages
Base requirements
sudo apt-get install build-essential sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
GStreamer support (recommended)
This is required for using the onboard camera
sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
Python Support
sudo apt-get install python2.7-dev sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
OpenGL Support
sudo apt-get install libgtkglext1 libgtkglext1-dev sudo apt-get install qtbase5-dev
video4linux2 support (better handling of usb cameras modes)
sudo apt-get install libv4l-dev v4l-utils qv4l2 v4l2ucp
Installing OpenCV 3.3
Downloading Sources
Version previous to 3.3 don't provide correct support for CUDA in the board
wget --no-check-certificate -O OpenCV-3.3.0.zip https://sourceforge.net/projects/opencvlibrary/files/opencv-unix/3.3.0/opencv-3.3.0.zip/download unzip OpenCV-3.3.0.zip cd opencv-3.3.0
Compiling
mkdir build cd build cmake -D WITH_CUDA=ON -D CUDA_ARCH_BIN="6.2" -D CUDA_ARCH_PTX="" -D WITH_LIBV4L=ON -D CMAKE_BUILD_TYPE=RELEASE -D WITH_LIBV4L=ON -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF -D WITH_GSTREAMER=ON -D WITH_CUBLAS=1 -D WITH_TBB=ON -D WITH_OPENGL=ON -D CMAKE_INSTALL_PREFIX=/usr/local ..
Installing
make -j6 sudo make install
Applying Patch
If you find the following mistake while running the make command:
/usr/local/cuda-8.0/include/cuda_gl_interop.h:64:2: error: #error Please include the appropriate gl headers before including cuda_gl_interop.h #error Please include the appropriate gl headers before including cuda_gl_interop.h
The following patch must be applied to the /usr/local/cuda-8.0/include/cuda_gl_interop.h file:
diff --git a/cuda_gl_interop.h b/cuda_gl_interop.h index 0f4aa17..e8c538c 100644 --- a/cuda_gl_interop.h +++ b/cuda_gl_interop.h @@ -59,13 +59,13 @@ #else /* __APPLE__ */ -#if defined(__arm__) || defined(__aarch64__) -#ifndef GL_VERSION -#error Please include the appropriate gl headers before including cuda_gl_interop.h -#endif -#else +//#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 +//#endif #endif /* __APPLE__ */
In order to apply the patch copy the code on a file named cuda.patch an locate this file on the directory where the cuda_gl_interop.h file is located and run the following command:
patch < cuda.patch
The following command might also be necessary:
cd /usr/lib/aarch64-linux-gnu/ sudo ln -sf tegra/libGL.so libGL.so
