Systems and methods for reducing straylight reflections

Abstract

A system includes a camera module located within a vehicle, a linear polarizer module positioned in a field of view of the camera module, and a control module in communication with the camera module and the linear polarizer module. The camera module is configured to acquire image frames depicting scenery external to the vehicle and transmit the image frames to a perception pipeline of the vehicle. The control module is configured to receive an image frame from the camera module, analyze the image frame to identify whether a reflection is present, and in response to identifying the reflection in the image frame, selectively activate the linear polarizer module to remove the reflection from a subsequent image frame captured by the camera module. Other example systems and methods for removing reflections from image frames captured by camera modules located within vehicles are also disclosed.
