其中红色部分为重点。之前摄像头无法驱动,重新编译后改动的地方为dc1394.2和v4l那个(原来显示为1/1,现在为Using libv4l)。
测试程序选用sample:camshiftdemo,可以清晰捕捉到图像。
1.配置关键在于opencv的前期安装(关于视频IO的):
apt-get install ffmpeg libavcodec-dev libavcodec52 libavformat52 libavformat-dev
apt-get install libgstreamer0.10-0-dbg libgstreamer0.10-0 libgstreamer0.10-dev
apt-get install libxine1-ffmpeg libxine-dev libxine1-bin
apt-get install libunicap2 libunicap2-dev
apt-get install libdc1394-22-dev libdc1394-22 libdc1394-utils
apt-get install swig
apt-get install libv4l-0 libv4l-dev
apt-get install python-numpy
apt-get install libpython2.6 python-dev python2.6-dev #You must install this for python support
2.准备完后,用svn获得最新的opencv:
cd ~/
svn co https://code.ros.org/svn/opencv/trunk
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON ..
sudo make
sudo make install
3.测试
g++ `pkg-config opencv --libs --cflags opencv` -o camshiftdemo camshiftdemo.cpp
./camshiftdemo
有BUG说缺东西的试试export LD_LIBRARY_PATH=你的lib地址
