Photonics Technologies used in Disaster Response Robots

Abstract

This paper first introduces some examples where photonics technology such as LiDAR (Light Detection and Ranging) is used to construct a 2D/3D environment map of disaster sites in various disaster response robots. A big problem with LiDAR is that it requires very large computational resources to process a huge amount of point cloud data. Therefore, in the latter half of this paper, we introduce some attempts of our research group to efficiently extract useful information from a huge amount of point cloud data.
