Camera focus

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

The tool can be launched with:

kalibr_camera_focus --topic [IMAGE_TOPIC]
