LOCUS: A Multi-Sensor Lidar-Centric Solution for High-Precision Odometry and 3D Mapping in Real-Time

Precise and dependable odometry (the estimation of robotic motion) is crucial in autonomous robotic behaviors.

Precise and dependable odometry (the estimation of robotic motion) is crucial in autonomous robotic behaviors. Now, LiDAR sensors are utilised to give substantial-fidelity, extensive-variety 3D measurements. On the other hand, they can battle in difficult settings, like in the existence of fog, dust, and smoke, or the absence of notable perceptual features.

A new examine proposes LOCUS (Lidar Odometry for Regular procedure in Uncertain Settings). It enables strong actual-time odometry in perceptually-stressing settings. Assorted sensor inputs are linked in a loosely-coupled switching plan so that the program can face up to the loss or fall short of some sensor channels. Moreover, it can be flexibly adapted to various systems with different sensor inputs and computational.  Experiments present the superiority of LOCUS in terms of accuracy, computation time, and robustness when compared to state-of-the-artwork algorithms.

A dependable odometry source is a prerequisite to empower complex autonomy conduct in subsequent-era robots working in severe environments. In this get the job done, we existing a substantial-precision lidar odometry program to realize strong and actual-time procedure less than hard perceptual ailments. LOCUS (Lidar Odometry for Regular procedure in Uncertain Settings), presents an precise multi-phase scan matching device geared up with an health-conscious sensor integration module for seamless fusion of more sensing modalities. We evaluate the performance of the proposed program against state-of-the-artwork methods in perceptually hard environments, and display best-course localization accuracy together with sizeable enhancements in robustness to sensor failures. We then display actual-time performance of LOCUS on several forms of robotic mobility platforms associated in the autonomous exploration of the Satsop electrical power plant in Elma, WA where the proposed program was a crucial aspect of the CoSTAR team’s option that received initial location in the City Circuit of the DARPA Subterranean Problem.
