Abstract
A method is provided for collaboratively detecting tangible bodies in an environment employing a plurality of distance sensors with which respective carriers are equipped, including: for each sensor, acquiring a series of measurements of distance of a closest tangible body along a line of sight; applying an inverse model of the sensor on a local occupancy grid; and constructing a consolidated local occupancy grid via Bayesian fusion of the occupancy probabilities thus determined; and, computing occupancy probabilities of the cells of a global occupancy grid via Bayesian fusion of the occupancy probabilities of corresponding cells of at least certain of said consolidated local occupancy grids. A system for implementing such a method is also provided.
