Chapter 9. Computer Vision

ROS provides basic support for Computer Vision. First, drivers are available for different cameras and protocols, especially for FireWire (IEEE1394a or IEEE1394b) cameras. An image pipeline helps with the camera calibration process, distortion rectification, color decoding, and other low-level operations. For more complex tasks, you can use OpenCV and the cv_bridge and image_transport libraries to interface with it and subscribe and publish images on topics. Finally, there are several packages that implement algorithms for object recognition, augmented reality, visual odometry, and so on.

Although FireWire cameras are best integrated in ROS, it is not difficult to support other protocols, such as USB and Gigabit Ethernet. ...
