Before You Start

Install ar_recog
svn co http://brown-ros-pkg.googlecode.com/svn/trunk/experimental/ar_recog ar_recog; roscd ar_recog; rosmake

Make mk_patt

You only have to do this once per install.

roscd ar_recog<br /> cd src/ARToolKit/util/mk_patt<br />

now edit mk_patt.c

change: # if defined(AR_INPUT_GSTREAMER)<br /> char                   *vconf = "videotestsrc";<br />

to: # if defined(AR_INPUT_GSTREAMER)<br/> char                   *vconf = "v4l2src device=/dev/video0 ! video/x-raw-rgb ! ffmpegcolorspace ! identity name=artoolkit ! fakesink";<br/>

or whatever gstreamer config is appropriate for the camera you want to do (not the change from ros to artoolkit).

Make mk_patt:
