how to run this package with usb camera

[walkeryu123]

  I can run  this package and usb_cam  separately, image topic is published in /usb_cam/image_raw, how do I edit the launch file can this package get the image from the usb camera ?

They have left out the remapping of the topics. I've made a PR here, that adds the topics to the launch file.

Hi, I also felt the usage of apriltags in ros is not well documented yet.
So I tried to manage. Here https://github.com/xenobot-dev/apriltags_ros

<remap from="/image_rect" to="/usb_cam/image_raw" />

modify example.launch to have a quick test with usb_cam pkg;

修改下launch中话题映射，就能跑起来拉
