Overview

This package is an ROS wrapper for ARToolkit.

ar_pose provides two nodes you can run. The program ar_single provides a transform between the camera and a single AR Marker. The program ar_multi provides an array of transforms for multiple markers.

Calibration Requirements

Currently the ar_pose package requires calibration information from a camera_info topic. If there is no camera_info topic the marker pose estimation will not start.

Examples

You can run ar_pose on a live video from a camera, or on a pre-recorded bag file that comes with the package. First, make sure you have ar_tools metapackage downloaded and installed and built.

Prerecorded Demo: Tracking a single marker

This demo uses ar_single to track the location of an AR Marker relative to the location of a fixed camera. The position of the camera in the world frame is published by static_tf_publisher as a static transform. The tracking process is visualized in rviz.

Download Warning The setup_single.sh script currently downloads a 350MB file.

First, make sure you have built the additional packages necessary for the demo:

   1 rosmake rviz rosbag

Next, download the example image data and run the demo.

   1 roscd ar_pose/demo
   2 ./setup_single.sh
   3 roslaunch ar_pose demo_single.launch

You should then see something similar to the video below:

Prerecorded Demo: Tracking the camera position

This demo uses ar_single to track the position of the camera relative to the location of an AR Marker. The position of the marker in the world frame is published by static_tf_publisher as a static transform. The tracking process is visualized in rviz.

Download Warning The setup_reverse.sh script currently downloads a 177MB file.

First, make sure you have built the additional packages necessary for the demo:

   1 rosmake rviz rosbag

Next, download the example image data and run the demo.

   1 roscd ar_pose/demo
   2 ./setup_reverse.sh
   3 roslaunch ar_pose demo_reverse.launch

You should then see something similar to the video below:

Prerecorded Demo: Tracking multiple markers

This demo uses ar_multi to track the location of multiple AR Markers relative to the location of a fixed camera. The position of the camera in the world frame is published by static_tf_publisher as a static transform. The tracking process is visualized in rviz.

Download Warning The setup_multi.sh script currently downloads a 177MB file.

First, make sure you have built the additional packages necessary for the demo:

   1 rosmake rviz rosbag

Next, download the example image data and run the demo.

   1 roscd ar_pose/demo
   2 ./setup_multi.sh
   3 roslaunch ar_pose demo_multi.launch

Live video examples

Two examples are provided that are configured and calibrated for use with a Logitech C600 webcam and the usb_cam driver.

The single-marker example that is provided uses the patt.hiro marker. A .pdf of this marker can be found in ~/ros/stacks/ccny-ros-pkg/ccny_vision/artoolkit/build/artoolkit-svn/patterns/pattHiro.pdf

   1 roslaunch ar_pose ar_pose_single.launch

A multi-marker configuration can be started as well. The Markers used in this example are found in ~/ros/stacks/ccny-ros-pkg/ccny_vision/data/4x4/4x4_ps.tar.gz The 4x4 patterns were created with patternMaker which was developed by David Johnson, Christopher Berthiaume and Bryan Witkowski. These patterns are distributed with this software under the GPL with permission.

   1 roslaunch ar_pose ar_pose_single.launch
