Abstract:

This paper describes a method of incorporating sensor and localisation uncertainty into contextual occupancy maps to provide for robust mapping. This paper builds on a recently proposed application of the Gaussian process (GP) to occupancy mapping. An extension of GPs is employed which incorporates uncertain inputs into the covariance function. In turn, this allows statistically consistent, multi-resolution maps to be constructed which exploit the spatial inference properties of GPs while correctly accounting for sensor and localisation errors. Experiments are described, with both synthetic and real data, which show the benefits of complete uncertainty modeling and how contextual occupancy maps may be constructed by fusing data from different sensors on different robots in a common probabilistic representation.
