安装 Opencv 3.2 on Ubuntu 16.04 并创建node测试
step 1: 安装一些package
sudo apt-get -y install libopencv-dev build-essential cmake git libgtk2.0-dev pkg-config python-dev python-numpy libdc1394-22 libdc1394-22-dev libjpeg-dev libpng12-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev libtbb-dev libqt4-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils unzip
step 2: 创建新的文件夹作为OpenCV的目录
mkdir opencv
step 3: 将路径转到OpenCV的目录
cd opencv
step 4: 下载OpenCV的安装包
wget https://github.com/Itseez/opencv/archive/3.2.0.zip -O opencv-3.2.0.zip
step 5: 解压OpenCV的安装包
unzip opencv-3.2.0.zip
step 6: 将路径转到opencv-3.2.0的目录
cd opencv-3.2.0
step 7: 创建build文件夹
mkdir build
step 8: 将路径转到build文件夹
cd build
step 9: 运行cmake
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D WITH_V4L=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..
step 10: 运行make
make -j $(nproc)
step 11: 运行install
sudo make install
step 12: 运行bash
sudo /bin/bash -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'
step 13: 运行配置
sudo ldconfig
step 14: 重启
Reboot your machine and run following command to check installed version
step 15: 查询版本
pkg-config --modversion opencv
安装成功！可以创建一个node测试了！
ROS node:
在自己的 package 的 src 目录下创建自己的.cpp file.
修改 CMakeLists.txt 和 package.xml, 主要是为了添加 opencv 的头文件 header files 路径 和 libraries 路径, target_link_libraries( 你的可执行文件名 ${catkin_LIBRARIES} $(OpenCV_LIBARARIES))
