This paper presents a novel algorithm capable of generating multiple next best views (NBVs), sorted by achievable information gain. Although being designed for waypoint generation in autonomous airborne mapping of outdoor environments, it works directly on raw point clouds and thus can be used with any sensor generating spatial occupancy information (e.g. LIDAR, kinect or Time-of-Flight cameras). To satisfy time-constraints introduced by operation on UAVs, the algorithm is implemented on a highly parallel architecture and benchmarked against the previous, CPU-based proof of concept. As the underlying hardware imposes limitations with regards to memory access and concurrency, necessary data structures and further performance considerations are explained in detail.
