E.L.S.

Extended Localization System

The E.L.S. (Extended Localization System) is used to localize automated vehicles just by the environment without artificial markers.

The hardware basis is an industrial PC (1). In addition to vehicle odometry (2) safety laser scanners (3) or dedicated 2D or 3D lidars (e. g. Velodyne VLP-16) (4) can be used. For map generation, the vehicle is only guided manually through the environment. Based on this map the vehicle‘s position can be localized. The procedure is tolerant towards environmental changes. E.L.S. has already been successfully used in numerous indoor and outdoor applications.
