i have used camera_calibration to generate my desired calibration info . but ,how can i apply this data to my application. i can see the original calibration info by

" rostopic echo /usb_cam/camera_info".
and how can i find the location of the "/usb_cam/camera_info",

then edit it by replacing by the previous calibration.

in a word,where does my camera driver store its calibration information ? thanks!!!

The standard place to put the camera calibration file is in ~/.ros/camera_info/. For example the camera calibration node will export the calibration result for usb_cam to ~/.ros/camera_info/usb_cam.yaml.
