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.

Camera core monitor using gradient filter

A camera agnostic core monitor for an enhanced flight vision system (EFVS) is disclosed. In embodiments, a structured light projector (SLP) generates and projects a precise geometric pattern or other like artifact, which is reflected by collimating elements into the EFVS optical path. Within the optical path, the EFVS focal plane array is illuminated by, and detects, the projected artifacts within the scene imagery captured for display by the EFVS. Image processors assess the presentation of the detected artifacts (e.g., position/orientation relative to the expected presentation of the detected artifact within the scene imagery) to verify that the displayed EFVS imagery is not misleading.

Camera agnostic core monitor incorporating projected images with high spatial frequency

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, a light source configured to emit light, a mask including one or more prisms configured to direct the light, and one or more pinholes configured pass the light directed from the one or more prisms, and a controller communicatively coupled to the one or more image sensors. The controller is configured to: receive an image of the surrounding environment of the aircraft from the one or more image sensors, wherein the image includes an artifact based on the light passed by the one or more pinholes; determine centroid data and extent data of the artifact in the image; and determine an orientation of the artifact in the image with respect to a calibration artifact using the centroid data and the extent data.
