Robust robot localization in a complex oil and gas industrial environment

In this paper, we propose a LiDAR‐based robot localization method in a complex oil and gas environment. Localization is achieved in six degrees of freedom (DoF) thanks to a particle filter framework. A new time‐efficient likelihood function, based on a precalculated three‐dimensional likelihood field, is introduced. Experiments are carried out in real environments and their digitized point clouds. Six DoF real‐time localization is achieved with spatial and angular errors of less than 2.5 cm and 1°, respectively, in a real environment of . The proposed approach focuses on real‐time performance on embedded platforms. It enabled the Vikings team to win the first two ARGOS Challenge contests.
