In one example, a method includes capturing, by an array of infrared sensors mounted on a vehicle, a thermal image of a scene during navigation of the vehicle and/or while the vehicle is stationary. The thermal image comprises a plurality of pixel values. Each infrared sensor of the array is associated with a respective one of the plurality of pixel values. The method further includes determining temperature data associated with a portion of the scene, where the portion is associated with a subset of the plurality of pixel values. The method further includes generating a correction value based on the thermal image and the temperature data. Related systems, vehicles, and devices are also provided.

The present disclosure provides a temperature measurement method, a temperature measurement device, an electronic apparatus and a computer-readable storage medium. The method includes obtaining an image frame pair including a target object by a visible light camera and a thermal imaging camera, and a blackbody being also set in an image acquisition region of the thermal imaging camera; determining a measured temperature of the target object based on the image frame pair; performing a blackbody detection on the infrared image to obtain a detection result of the blackbody; determining a measured temperature of the blackbody based on the detection result of the blackbody and the infrared image; and correcting the measured temperature of the target object according to the measured temperature of the blackbody and a preset temperature of the blackbody, a corrected temperature being used as a temperature measurement result of the target object.

Systems and methods based on thermal imaging for rapid detection of fever conditions in humans that provide for extremely inexpensive, mass producible, field deployable devices accurate in specific, relatively low temperature ranges, and in particular temperatures near nominal human body temperature. The system may include a thermal imager tailored for the application and a corresponding mass producible controlled temperature calibration source configured to provide real time calibration near the human body temperature of interest. The imager and source are deployed in a way such that target people and the calibration source will be within the imager FOV for fever detection. The combination of real time near measurement temperature calibration, with suitable thermography approaches, yield fast, accurate measurements in the fever range using low cost, easy-to-produce components. In combination with a visible imager and pattern/facial recognition techniques, detection of a human target's facial regions of interest suitable for fever detection can be accurately accomplished.

A method for aligning a projected beam on a reflector in a reflective-type beam detector, the method including adjusting the projected beam so as to: project on to substantially all, if not all, of a reflective surface of the reflector; or project on to at least a portion of a reflective surface of the reflector until a constant, or within a predetermined threshold of a constant, signal is received from the reflector; and detecting one or more edges of the reflective surface of the reflector and thereby: centering the projected beam, so as to align an approximate center of the projected beam on, or within a predetermined threshold of, an approximate center of the reflective surface of the reflector; and/or determining a shape or profile of the reflector.
