OpenCV is also integrated into ROS, mainly for image processing. The vision_opencv ROS stack includes the complete OpenCV library and the interface with ROS.
The vision_opencv meta package consists of individual packages:
- cv_bridge: This contains the CvBridge class. This class converts ROS image messages to the OpenCV image data type and vice versa.
- image_geometry: This contains a collection of methods to handle image and pixel geometry.
The following diagram shows how OpenCV is interfaced with ROS:
OpenCV-ROS interfacing
The image data types of OpenCV are IplImage and Mat. If we want to work with OpenCV in ...
