Real-time embedded large-scale place recognition for autonomous ground vehicles using a spatial descriptor

Abstract: Place recognition is a key task in an autonomous vehicle's Simultaneous Localization and Mapping (SLAM). The motion estimation is bound to drift over time due to cumulative errors. Fortunately, the correct identification of a revisited area provided by the place recognition module enables further optimizations that correct drifting errors if detected in realtime. Place recognition based on structural information of the scene is more robust to luminosity changes that can lead to false detections in the case of … Show more
