METHOD FOR BUILDING A MAP OF PROBABILITY OF ONE OF ABSENCE AND PRESENCE OF OBSTACLES FOR AN AUTONOMOUS ROBOT

摘要

The invention relates to a method to compute a pixel map of probabilities of one of absence and presence of an obstacle in the environment of an autonomous robot. Autonomous robot comprises at least one sensor grouped in at least one set of sensors that detect obstacles of similar types and have its own sensor initial map of probability of absence of obstacles. The method comprises the steps of initializing, a map around the robot and attached to the robot with a predefined value of probability of absence or presence of an obstacle, acquiring data representative of the absence or presence of an obstacle around the robot from at least one sensing procedure, and concurrently updating values of probabilities using data from sensing procedure and modifying the probabilities of absence or presence of obstacle from previous observations to a value closer to a predefined value.
