  • Patent number: 12207016
    Abstract: Techniques for facilitating temperature compensation are provided. In one example, an infrared imaging system includes a focal plane array configured to capture radiation from a scene and generate image data based on the radiation. The focal plane array further captures radiation from an element associated with the infrared imaging system during capture of the radiation from the scene. The infrared imaging system further includes a temperature sensor configured to determine a temperature of the focal plane array. The infrared imaging system further includes a processing circuit configured to determine a temperature associated with the element based on the temperature of the focal plane array. The processing circuit is further configured to determine a temperature associated with an object in the scene based on the infrared image data, the temperature associated with the element, and the temperature of the focal plane array. Related devices and methods are also provided.

  • Publication number: 20240240989
    Abstract: Techniques for atmospheric absorption determination using embedded sensor data are provided. In one example, a system includes a housing. The system further includes a sensing device within the housing. The sensing device is configured to determine a humidity within the housing and a temperature within the housing. The system further includes a logic device. The logic device is configured to compensate the humidity and the temperature based on a location of the sensing device within the housing relative to heat sources within the housing. The logic device is further configured to determine a moisture value based on compensation of the humidity and the temperature. The logic device is further configured to determine an atmospheric absorption value based on the moisture value. Related devices and methods are also provided.

  • Publication number: 20230043342
    Abstract: 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.
