Embodiments of the present disclosure provide a method for temperature detection. The method comprises obtaining a sensed temperature from a sensor, the sensor being in a mounted mode where the sensor is thermally radiated by a variable heat source and a fixed heat source; determining a temperature change rate of the sensor and at least one affecting factor that affects temperature sensing of the sensor; and determining a temperature of the variable heat source based on the sensed temperature, the temperature change rate, and the affecting factor. According to the method of the present disclosure, the temperature of the variable heat source such as an ambient temperature can be obtained or determined without a dedicated sensor and cables. With this method, the ambient temperature can be determined by a sensor for sensing a temperature of a heating element such as a battery, a control unit or the like. In this way, extra spaces and product designs for mounting a dedicated sensor for the ambient temperature are no longer needed, which reduces costs of the product. Furthermore, user experience can be improved without increasing costs.

A thermographic camera control method includes periodically correcting a display temperature of a temperature distribution image at a first interval; and acquiring the temperature distribution image by periodically imaging a temperature measurement target by the thermographic camera at a second interval. The acquiring the temperature distribution image includes imaging the temperature measurement target after elapse of a standby time. The standby time is shorter than the second interval and starts from the correcting the display temperature.

Techniques for facilitating non-uniformity correction calibrations are provided. In one example, an infrared imaging system includes an infrared imager and a logic device. The infrared imager is configured to capture a first set of infrared images of a reference object using a first integration time. The infrared imager is further configured to capture a second set of infrared images of the reference object using a second integration time different from the first integration time. The logic device is configured to determine a dark current correction map based on the second set of infrared images. The logic device is further configured to generate a non-uniformity correction map based on the dark current correction map. Related devices and methods are also provided.

Embodiments disclosed herein include a method for determining a temperature error of a pyrometer. In an embodiment, the method comprises measuring a first signal with a first sensor of the pyrometer and measuring a second signal with a second sensor of the pyrometer.

In an example, a thermal imaging test article comprises a block configured to be attached to a blackbody on a back side of the block, the block having a variable thickness to represent facial features of a human face, the block including a cutout to allow a thermal imaging device to see the blackbody behind the block through the cutout, and one or more heaters thermally coupled to the block to produce heat to heat the block. The variable thickness of the block and the heat produced by the one or more heaters are selected to simulate thermally the human face on a front side of the block.

A method comprises capturing outputs of a VLC and an infrared array sensor (IAS). A memory includes a calibration based on a position of a laser pointer relative to the IAS. The method includes the laser pointer outputting a light beam to produce a laser dot on a target. The output of the VLC includes a representation of the laser dot. The output of the IAS includes values indicative of infrared radiation from the target. The method includes determining a temperature based on a portion of the values indicative of infrared radiation from the target. The portion of the values includes values associated with a portion of the target at which the laser dot is produced. The method includes displaying, on the display, the output of the VLC and the temperature. Displaying the output of the VLC includes displaying a visible light image showing the laser dot and at least a portion of the target.
