An infrared camera assembly for a vehicle. The assembly includes: a vehicle component having a front surface; a shutterless far-infrared (FIR) camera mounted within the vehicle component, wherein the shutterless FIR camera is utilized to output at least one thermal video stream processed by the autonomous vehicle system; and a protective window disposed on at least a portion of the front surface of the vehicle component, where the protective window is positioned to be aligned with a lens of the FIR camera, so as to allow the shutterless FIR camera to capture images therethrough.

A method of quantifying gas leak rate includes receiving image frames acquired with a camera and including a plume from a gas leak source, determining a real-world size that each pixel represents, identifying pixels corresponding to the plume in a first image frame, calculating gas concentration path lengths of the plume for the pixels in the first image frame, calculating, based on the first image frame and a second image frame, an image velocity field of the plume including displacement vectors for the pixels, identifying, within the first image, a closed boundary enclosing the gas leak source of the plume, and calculating a first gas leak rate in the first image frame by calculating a volume rate of the plume flowing across the closed boundary based on the image velocity field, the gas concentration path lengths, and a time interval between the first and the second image frames.

An optical isolation system is disclosed for use in a display to reduce light that is transmitted from one or more light sources to a camera. The system can include a gasket arranged next to the camera, where the gasket includes an aperture that substantially surrounds a region that is adjacent to a lens of the camera. In some cases, the gasket can reduce optical crosstalk associated with visible light as well as infrared light. The gasket can include a material that is optical opaque to the wavelengths of the light being transmitted. In addition, some layers of the display can include optical disrupting regions formed in a thickness of the layer.

A method of controlling FPA system stabilization includes calculating FPA adjustments as a function of FPA temperature and adjusting a TEC set point to assist the FPA adjustments in attaining a predetermined level of FPA performance. Adjusting the TEC set point can include adjusting the TEC set point as a function of at least one of ambient temperature, FPA temperature, or disparity between the predetermined level of FPA performance and a level of FPA performance obtainable by calculating the FPA adjustments as a function of FPA temperature alone without adjusting the TEC set point.

The iris recognition device includes an iris camera module used for collecting iris characteristics of a user, and at least one fill light component used for providing a supplementary light source for the iris camera module. When the iris recognition device is used for collecting the iris characteristics of the user, the supplementary light source provided by the fill light component reduces reflective spots on the iris or make reflective spots in areas other than iris such as sclera and pupil, thereby improving precision of the collected iris characteristics of the user.

Dual-aperture digital cameras with auto-focus (AF) and related methods for obtaining a focused and, optionally optically stabilized color image of an object or scene. A dual-aperture camera includes a first sub-camera having a first optics bloc and a color image sensor for providing a color image, a second sub-camera having a second optics bloc and a clear image sensor for providing a luminance image, the first and second sub-cameras having substantially the same field of view, an AF mechanism coupled mechanically at least to the first optics bloc, and a camera controller coupled to the AF mechanism and to the two image sensors and configured to control the AF mechanism, to calculate a scaling difference and a sharpness difference between the color and luminance images, the scaling and sharpness differences being due to the AF mechanism, and to process the color and luminance images into a fused color image using the calculated differences.

Systems and methods are directed to vertical legs for an infrared detector. For example, an infrared imaging device may include a microbolometer array in which each microbolometer includes a bridge and a vertical leg structure that couples the bridge to a substrate such as a readout integrated circuit. The vertical leg structure may run along a path that is parallel to a plane defined by the bridge and may be oriented perpendicularly to the plane. The path may be disposed within, below, or above the plane defined by the bridge.

A work vehicle for managing lawn while traveling incudes a positioning module for outputting positioning data, a self-vehicle position calculation section for calculating a self-vehicle position based on the positioning data, an activity determination device for determining activity of the lawn, and a lawn condition information generation section configured to generate lawn condition information by correlating the activity with the self-vehicle position as a determination point of the activity.
