Abstract
An autonomous vehicle includes interior sensors including an IR camera and a visible light camera. Images of an interior of the vehicle are captured using the cameras both before and after a passenger rides in the vehicle. The IR images from before and after are subtracted to obtain a difference image. Pixels above a threshold intensity a clustered. Clusters having an above-threshold size are determined to be anomalies. Portions of images from the visible light camera corresponding to the anomalies are sent to a dispatcher, who may then clear the vehicle to pick up another passenger or proceed to a cleaning station. Anomalies may be identified based on a combination of the IR images and visible light images.
