Cornell's AGV from the DARPA Urban Challenge was upgraded and used to experimentally examine if and how state-of-the-art vision algorithms can complement or replace lidar and radar sensors.  ...  Additionally a state-of-the-art vision detection algorithm that includes heading information for autonomous ground vehicle (AGV) applications was implemented.  ...  New person clustering is implemented by extending Laplacian of Gaussians (LoG) filtering typically used in image processing to lidar processing.  ...
