ros 与 opencv

opencv与ros通过 cv bridge连接。kinect v2又通过kinect2_bridge连接：This is a bridge between libfreenect2 and ROS.

opencv版本问题

iai_kinect2支持indigo和hydro，一定要用opencv2，他里面明确提到了要用 opencv 2.4.x
2.4.9还不行，因为要imencode，我用了2.4.13

上面有关连接中说到了ros如何处理多版本的opencv。

开始tutorial

解决：把原来的find_package(OpenCV REQUIRED)改为

set(OpenCV_DIR “/home/xy/software/opencv-2.4.13/build”)
find_package(OpenCV 2 REQUIRED)
