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
cd src/ARToolKit/util/mk_patt
now edit mk_patt.c
change:
# if defined(AR_INPUT_GSTREAMER)
char *vconf = "videotestsrc";
to:
# if defined(AR_INPUT_GSTREAMER)
char *vconf = "v4l2src device=/dev/video0 ! video/x-raw-rgb ! ffmpegcolorspace ! identity name=artoolkit ! fakesink";
or whatever gstreamer config is appropriate for the camera you want to do (not the change from ros to artoolkit).
Make mk_patt:
make
Run mk_patt
roscd ar_recog
cd bin
../src/ARToolKit/bin/mk_patt
when prompted to enter your camera parameter filename, simply type:
camera_para.dat
This will use whatever camera_para.dat is located in your ar_recog/bin
You can now use mk_patt exactly as in the official documentation.
Using the Pattern File
Once you've made a pattern file, you will need to update/change your object_data file (located in ar_recog/bin). Again, ar_recog is strictly compatible with the official implementation.
