Abstract: A method of testing a candidate perception setup for an autonomous vehicle, comprising: receiving ground truth of a driving scenario run; providing a time-sequence of ground truth snapshots of the driving scenario run, wherein a decision making component independent of the ego agent determines a first time-sequence of decisions for the ground truth snapshots; providing a time-sequence of ablated snapshots of the driving scenario run, each ablated snapshot generated so as to cause a perception error that is representative of the candidate perception setup, wherein the decision making component determines a second time-sequence of decisions for the ablated snapshots; and computing a similarity measure between the first and second time-sequences of decisions denoting an extent to which the candidate perception setup caused a change in one or more decisions points of the second time-sequence relative to the first time-sequence, a decision point occurring when a decision changes between adjacent timesteps.

Abstract: An imaging system for an autonomous vehicle comprises a camera for capturing images within a first field of view, a transparent disc arranged in front of the camera such that the transparent disc covers the field of view of the camera, an actuator configured to rotate the transparent disc, and a mounting arrangement configured to mount the camera, the transparent disc and the actuator on an autonomous vehicle. Also described is an imaging system comprises a camera for capturing images within a first field of view through a transparent surface, and a fluid dispenser constructed and arranged to spray a fluid onto the transparent surface within the first field of view. Also described is an image capture system for an autonomous vehicle comprising two such cameras with respective transparent discs and actuators.
