Abstract:
A perception system for a motor vehicle includes a camera with a lens having a field of view and configured to focus incident light from the field of view. The field of view includes a road having a road surface. The perception system also includes an imaging sensor arranged in the camera. The imaging sensor has a photosensitive surface defined by an imaging surface area configured to capture the incident light focused from the field of view. A first portion of the imaging surface area is configured to capture an image of the road. The perception system further includes a first polarizer array arranged across the first portion of the imaging surface area and configured to reduce glare from the road surface.
