Collaborative data processing

Abstract

Embodiments are disclosed for collaboratively scanning and processing sensor data for building a map of an environment around a group of vehicles. An example an in-vehicle computing system of a vehicle includes a sensor subsystem in communication with an optical sensor, a processor, and memory storing instructions executable by the processor to instruct the optical sensor to scan an assigned region around the vehicle, receive locally scanned data corresponding to the assigned region, process the scanned data to build a first portion of a three-dimensional map, transmit the processed scanned data to at least one other vehicle, receive additional map data from the at least one other vehicle, and build a second, different portion of the three-dimensional map using the received additional map data. In a first example of the in-vehicle computing system, the optical sensor may additionally or alternatively include a Light Detection and Ranging (LiDAR) sensor system.
