velo2cam_calibration

The velo2cam_calibration software implements a state-of-the-art automatic calibration algorithm for pair of sensors composed of LiDAR and camera devices in any possible combination [1]. This software is provided as a ROS package.

Package developed at Intelligent Systems Laboratory, Universidad Carlos III de Madrid.

Setup

To install this ROS package: 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.
