Setup

This software is provided as a ROS package. To install:

1. Clone the repository into your catkin_ws/src/ folder.
2. Install run dependencies: sudo apt-get install ros-<distro>-opencv-apps
3. Build your workspace as usual.

Usage

See HOWTO.md for detailed instructions on how to use this software.

To test the algorithm in a virtual environment, you can launch any of the calibration scenarios included in our Gazebo validation suite.

Calibration target

The following picture shows a possible embodiment of the proposed calibration target used by this algorithm and its corresponding dimensional drawing.

Note: Other size may be used for convenience. If so, please configure node parameters accordingly.
