Camera focus

#Camera focus (not in CDE)

This ROS node helps you with setting the focus of a camera in reproducible way. The tool subscribes to the camera's image topic and present you the live image along with a measure of focus. Point the camera at a scene with high frequency components (e.g. Siemens star) and adjust the focus while trying to minimize the calculated focus index.

The tool can be launched with:

rosrun aslam_calibration camera_focus --topic /cam0/image_raw
