The present disclosure relates to combination of images. A method according to an embodiment comprises: receiving a visual image and an infrared (IR) image of a scene and for a portion of said IR image extracting high spatial frequency content from a corresponding portion of said visual image. The method according to the embodiment further comprises combining said extracted high spatial frequency content from said portion of the visual image with said portion of the IR image, to generate a combined image, wherein the contrast and/or resolution in the portion of the IR image is increased compared to the contrast and/or resolution of said received IR image.

Infrared resolution and contrast enhancement with fusion

Systems and methods include an image capture component configured to capture infrared images of a scene, and a logic device configured to identify a target in the images, acquire temperature data associated with the target based on the images, evaluate the temperature data and determine a corresponding temperature classification, and process the identified target in accordance with the temperature classification. The logic device identifies a person and tracks the person across a subset of the images, identify a measurement location for the target in a subset of the images based on target feature points identified by a neural network, and measure a temperature of the location using corresponding values from one or more captured thermal images. The logic device is further configured calculate a core body temperature of the target using the temperature data to determine whether the target has a fever and calibrate using one or more black bodies.

Non-contact temperature measurement in thermal imaging systems and methods

An imager array may be provided as part of an imaging system. The imager array may include a plurality of infrared imaging modules. Each infrared imaging module may include a plurality of infrared sensors associated with an optical element. The infrared imaging modules may be oriented, for example, substantially in a plane facing the same direction and configured to detect images from the same scene. Such images may be processed in accordance with various techniques to provide images of infrared radiation. The infrared imaging modules may include filters or lens coatings to selectively detect desired ranges of infrared radiation. Such arrangements of infrared imaging modules in an imager array may be used to advantageous effect in a variety of different applications.

Imager with array of multiple infrared imaging modules

Various techniques are provided for implementing a segmented focal plane array (FPA) of infrared sensors. In one example, a system includes a segmented FPA. The segmented FPA includes a top die having an array of infrared sensors (e.g., bolometers). The top die may also include a portion of a read-out integrated circuit (ROIC). The segmented FPA also includes a bottom die having at least a portion of the ROIC. The top and the bottom dies are electrically coupled via inter-die connections. Advantageously, the segmented FPA may be fabricated with a higher yield and a smaller footprint compared with conventional FPA architectures. Moreover, the segmented FPA may be fabricated using different semiconductor processes for each die.

Segmented focal plane array architecture

Various techniques are disclosed for smart surveillance camera systems and methods using thermal imaging to intelligently control illumination and monitoring of a surveillance scene. For example, a smart camera system may include a thermal imager, an IR illuminator, a visible light illuminator, a visible/near IR (NIR) light camera, and a processor. The camera system may capture thermal images of the scene using the thermal imager, and analyze the thermal images to detect a presence and an attribute of an object in the scene. In response to the detection, various light sources may be selectively operated to illuminate the object only when needed or desired, with a suitable type of light source, with a suitable beam angle and width, or in otherwise desirable manner. The visible/NIR light camera may also be selectively operated based on the detection to capture or record surveillance images containing objects of interest.

Smart surveillance camera systems and methods

Various techniques are provided to monitor electrical equipment. In some implementations, a monitoring system for a cabinet may include an infrared camera and a non-thermal camera. The infrared camera may be configured to capture one or more thermal images of at least a portion of electrical equipment positioned in an interior cavity of the cabinet. The non-thermal camera may be configured to capture one or more non-thermal images such as visible light images of the portion of electrical equipment. In some implementations, combined images may be generated that include characteristics of the thermal images and the non-thermal images for viewing by a user. In some implementations, the cameras may receive electrical power through a physical coupling to an electrical connector within the cabinet and/or through electromagnetic energy harvesting techniques. Other implementations are also provided.

Electrical cabinet infrared monitor systems and methods

Systems and methods disclosed herein, in accordance with one or more embodiments, provide for the generation of a fused image optimized for a target resolution, such as by receiving an infrared (IR) image captured by an IR imaging sensor, receiving a visible light (VL) image captured by a VL imaging sensor, determining a scaling factor based on a difference between the target resolution and a baseline resolution, and determining a set of target fusion parameters at least by modifying, according to the scaling factor, a set of baseline fusion parameters associated with the baseline resolution. A fused image is generated having the target resolution at least by fusing the IR image and the VL image according to the set of target fusion parameters.

Fused image optimization systems and methods

Various techniques are disclosed to generate a contrast-enhanced combined image based on a thermal image and high spatial frequency content extracted from a visual light image, said images depicting the same scene. In one example, a method comprises: determining a blending measure indicating the quality of at least one of said images; combining luminance components of pixel values comprised in the thermal image and of pixel values representing high spatial frequency content comprised in the visual light image based on the blending measure; and generating a contrast-enhanced combined image based on the thermal image and the combined luminance components.

Contrast-enhanced combined image generation systems and methods

Various embodiments of the present disclosure may include an imaging device configured to determine appropriate conditions for updating non-uniformity correction (NUC) terms. In certain embodiments, the imaging device may determine when the imaging device is likely not in use and update NUC terms during the times when the imaging device is likely not in use. Data from various position sensors such as gyroscopes, accelerometers, global positioning system receivers, and/or other data may be used to determine when the imaging device is likely not in use. Such position sensors may be coupled to the imaging device and/or may be remote from the imaging device. In certain embodiments, while NUC terms are updated, imaging data obtained may be modified with historical data to provide usable data.

Smart non-uniformity correction systems and methods

A shutter assembly may be provided for an infrared imaging module to selectively block external infrared radiation from reaching infrared sensors of the infrared imaging module. For example, the shutter assembly may comprise a paddle situated external to an optical element (e.g., lens) and adapted to be selectively moved by an actuator to substantially block external infrared radiation from entering the optical element. The shutter assembly may be stacked relative to a housing of the infrared imaging module without excessively increasing the overall profile of the infrared imaging module. A substantially reflective low emissivity interior surface may be provided on the paddle to reflect infrared radiation originating from an infrared sensor assembly of the infrared imaging module back to the infrared sensor assembly.

Infrared imaging device having a shutter

Various techniques are disclosed for providing a device attachment configured to releasably attach to and provide infrared imaging functionality to mobile phones or other portable electronic devices. For example, a device attachment may include a housing with a tub on a rear surface thereof shaped to at least partially receive a user device, an infrared sensor assembly disposed within the housing and configured to capture thermal infrared image data, and a processing module communicatively coupled to the infrared sensor assembly and configured to transmit the thermal infrared image data to the user device. Thermal infrared image data may be captured by the infrared sensor assembly and transmitted to the user device by the processing module in response to a request transmitted by an application program or other software/hardware routines running on the user device.
