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:
make
