Summary
In this chapter, we have given you an overview of the Computer Vision tools provided by ROS. We started by showing how we can connect and run several types of cameras, particularly FireWire and USB ones. The basic functionality to change their parameters was presented, so now you can adjust certain parameters to obtain images of good quality. Additionally, we provided a complete USB camera driver example.
Then, we showed how you can calibrate the camera. The importance of calibration is the ability to correct the distortion of wide-angle cameras, particularly cheap ones. The calibration matrix also allows you to perform many Computer Vision tasks, such as visual odometry and perception.
We showed how you can work with stereo vision in ROS ...
