Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
