A method to recognize road terrain with 3D scanning

This research deals with a method to recognize road terrain for a robot to navigate near building. In order to move a robot in and around buildings, it is required to recognize some structured way of both indoor and outdoor environment such as slope, steps, stairs and so on. For that, a detection technique based on 3D scan and plane geometry was proposed in this research. By adopting preprocessing to extract lines from scan points, it can make planes effectively. Experiments with the proposed method to recognize the environment near building were carried out.
