Patent number: 11727595Abstract: A system uses a fleet of AVs to assess visibility of target objects. Each AV has a camera for capturing images of target objects. AVs provide the captured images, or visibility data derived from the captured images, to a remote system, which aggregates visibility data describing images captured across the fleet of AVs. The AVs also provide condition data describing conditions under which the images were captured, and the remote system aggregates the condition data. The remote system processes the aggregated visibility data and condition data to determine conditions under which a target object does not meet a visibility threshold.Type: GrantFiled: September 29, 2021Date of Patent: August 15, 2023Assignee: GM CRUISE HOLDINGS LLCInventors: Katherine Mary Stumpf, Andrew David Acosta
