Multi lidar system for fast obstacle detection

In recent year, much progress has been made in outdoor obstacle detection. However, for fast moving robotic platform, high-speed obstacle detection is still a daunting challenge. This paper describes laser based system for the fast obstacle detection. To do this, we introduce how to configure laser range finders by using a plane ruler for outdoor robotic platform. For high-speed obstacle detection, we use the gradient of points. We evaluate processing time and accuracy of our system by testing on real drive track including off-road course.
