Abstract
Methods and systems for collaboratively constructing a map of an environment. One or more sensory devices installed on an autonomous vehicle take readings within a field of view of the sensory device. As the vehicle moves within the environment, the sensory device continuously takes readings within new fields of view. At the same time, sensory devices installed on other autonomous vehicles operating within the same environment and/or fixed devices monitoring the environment take readings within their respective fields of view. The readings recorded by a processor of each autonomous vehicle may be shared with all other processors of autonomous vehicles operating within the same environment with whom a data transfer channel is established. Processors combine overlapping readings to construct continuously growing segments of the map. Combined readings are taken by the same sensory device or by different sensory devices and are taken at the same time or at different times.
