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

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.

Temperature compensation in infrared imaging systems and methods

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. The device attachment may include an infrared imagining module and a non-thermal imaging module that cooperate with one or more of a non-thermal imaging module in an attached device and a light source in the attached device for capturing and processing images.

Device attachment with dual band imaging sensor

Various embodiments of the present disclosure may include an imaging system that allows for the transfer of high dynamic range (HDR) radiometric thermal images over a low bitrate interface. The image system may capture HDR images and output the HDR images over a communications interface to be processed. The HDR images may be converted to low dynamic range (LDR) images by a transfer function in order to be sent over the low bitrate interface. An inverse transfer function may also be sent along with the LDR image. Once the LDR image has been sent over the low bitrate interface, the LDR image may be converted to a reconstructed image using the inverse transfer function.

High dynamic range radiometric thermal video over low bitrate interface

Various techniques are provided for calibrating a thermal imaging device using a non-contact temperature sensor. In one example, a method includes capturing a thermal image of a scene. The thermal image comprises a plurality of pixel values. The method also includes detecting, by a non-contact temperature sensor, a temperature value associated with a portion of the scene corresponding to a subset of the pixel values. The method also includes comparing the subset of pixel values with the detected temperature value. The method also includes generating a correction term based on the comparing. The method also includes applying the correction term to at least the subset of pixel values to radiometrically calibrate the subset of pixel values. Related systems and alignment processes are also provided.

Radiometric correction and alignment techniques for thermal imager with non-contact temperature sensor

Various techniques are provided for using one or more shielded (e.g., blinded, blocked, and/or obscured) infrared sensors of a thermal imaging device. In one example, a method includes capturing a signal from a shielded infrared sensor that is substantially blocked from receiving infrared radiation from a scene. The method also includes capturing a signal from an unshielded infrared sensor configured to receive the infrared radiation from the scene. The method also includes determining an average thermographic offset reference for the shielded and unshielded infrared sensors based on the captured signal of the shielded infrared sensor. The method also includes determining an absolute radiometric value for the scene based on the average thermographic offset reference and the captured signal of the unshielded infrared sensor.
