I am working with apriltags2_ros to try to do a simple tracking but am unable to set up my webcam to work with the apriltags2_ros package. I am using this link as a reference, http://wiki.ros.org/apriltags2_ros/Tutorials/Detection%20in%20a%20video%20stream
but when I launch the continuous_detection.launch and run rqt and image_view there is no image displayed from my webcam so how would I set it up to work with my webcam?
