Abstract
An imaging system for an aircraft is disclosed. The imaging system comprises one or more image sensors configured to image a surrounding environment of the aircraft, an artifact pattern on an optical component in an optical path of the one or more image sensors, and a controller communicatively coupled to the one or more image sensors. The controller includes one or more processors configured to execute program instructions causing the one or more processors to: receive an image of the surrounding environment of the aircraft from the one or more image sensors, wherein the image includes features of the artifact pattern, extract the features of the artifact pattern from the image, and determine an orientation of the features of the artifact pattern in the image with respect to a calibration artifact pattern.
