Systems and methods are provided for controlling access to a building or other restricted physical spaces using at least a facial recognition module, an access control panel and electronically lockable doors or other means of controlling access. The facial recognition module comprises visible light and IR detection. The facial recognition module initially uses visible light to detect a person in the vicinity of an access control location, defines a region of interest in at least a captured image related to the location of the person's face, tracks the movement of the face and adjusts the region of interest, and performs facial recognition by prioritizing analysis of the defined region of interest.

An autonomous vehicle includes interior sensors including an IR camera and a visible light camera. Images of an interior of the vehicle are captured using the cameras both before and after a passenger rides in the vehicle. The IR images from before and after are subtracted to obtain a difference image. Pixels above a threshold intensity a clustered. Clusters having an above-threshold size are determined to be anomalies. Portions of images from the visible light camera corresponding to the anomalies are sent to a dispatcher, who may then clear the vehicle to pick up another passenger or proceed to a cleaning station. Anomalies may be identified based on a combination of the IR images and visible light images.

A method for detecting light sources, including capturing an image including a sub-infrared light emitter, applying a filter to a pixel of the captured image to isolate a signal strength of a range of frequencies, and comparing the signal strength of the filtered pixel to an expected signal strength of a background spectra for the range of frequencies. As a result of a difference between the signal strength of the filtered pixel and the expected signal strength exceeding a predetermined threshold, the method includes identifying the pixel as corresponding to a light emitter. As a result of the difference between the signal strength of the filtered pixel and the expected signal strength not a predetermined threshold, the method includes identifying the pixel as not corresponding to a light emitter.

The present disclosure is directed to presenting a more realistic augmented reality view on a video see-through display of a device by configuring the device such that the displayed image of the real world substantially matches what would be perceived by the user if the display were not present. This may be implemented by determining one or more of: a distance from the user's eyes to the display of the device, and an angular offset between the optical axis of a rear camera of the device and the user's visual field, and using the determined distance and/or angular offset to adjust the image that is displayed to the user. The image that is displayed to the user may be adjusted by optically or digitally zooming the rear camera of the device. It may also be adjusted by tilting the rear camera or by digitally translating the displayed video feed.

Various implementations relate to an operator monitoring system (OMS). Certain implementations include an OMS coupled to a rotatable portion of a steering wheel assembly of a vehicle. For example, the OMS may include an imaging unit, such as a camera, that is coupled to a central hub portion of the steering wheel assembly. The imaging unit has a field of view directed toward one or more occupants in the vehicle and is configured to capture an image signal corresponding to an imaging area in the field of view. The imaging area can be configured to encapsulate an expected position of one or more vehicle occupants. The OMS also includes one or more processing units in electrical communication with the imaging unit that receives and processes the image signal from the imaging unit to determine an occupant state and, in some implementations, provide feedback based on the determined occupant state.

Imaging systems providing high resolution, low light images with significant dynamic range are disclosed. The improvements to photo imaging sensors providing low costs and yet higher performance sensors may be obtained an enhanced photosensor generating a single color channel image per photosensor. The single color channel image contains luminence values corresponding to light focused onto the photosensor. The plurality of photosensors are constructed using Indium gallium nitride (InGaN) nanowire structures and nanopyrimid structures used in cells within an array of cells. Photosensors may be constructed as single color imaging devices as well as multi-color devices. The generation of various color channel images are controlled using metasurface filter structures as well as color filter layers setting a wavelength for absorbed light by controlling a concentration of indium gallium nitride (InGaN) within the color filter layers.

An infrared (IR) imaging system for determining a concentration of a target species in an object is disclosed.

The optical system can have components defining at least two optical channels thereof, said at least two optical channels being spatially and spectrally different from one another. Each of the at least two optical channels can be positioned to transfer IR radiation incident on the optical system towards the optical FPA. The system can include a processing unit containing a processor that can be configured to acquire multispectral optical data representing said target species from the IR radiation received at the optical FPA. One or more of the optical channels may be used in detecting objects on or near the optical window, to avoid false detections of said target species.
