Abstract: A temperature estimation device (100) is provided with: an acquiring section (131) that acquires a photographed image photographed by a photographing section (110) including an infrared light sensor and a housing; a generating section (132) that corrects the photographed image with use of a correction parameter and a temporarily set temperature of the housing to generate a corrected image of the photographed image, the correction parameter that is calculated by prior temperature calibration with respect to the photographing section (110); and an estimating section (135) that estimates a temperature of the housing on the basis of non-uniformity of luminance values of pixels included in the corrected image.

Abstract: A high-precision non-contact temperature measurement device includes: a thermal insulation box made of a thermal insulation material and having therein a receiving space; a dynamic constant-temperature feedback control module for controlling temperature of the receiving space; and a non-temperature-sensing thermal imager disposed in the receiving space. The device achieves system thermal insulation within a non-contact temperature measurement gauge, maintains the overall closed system dynamically at constant temperature, compensates for effects of internal chip self-heating effect and visual field background temperature variation, and finally calculates average temperature of surfaces of a target precisely with an imaging, non-contact temperature measurement gauge and a temperature calibration algorithm widely used in thermal-imaging non-contact temperature measurement.

Abstract: A sensor device includes a passive infrared sensor, a control circuit, and a lens that directs infrared radiation onto the passive infrared sensor. The lens includes an obstruction that asymmetrically blocks transmission of infrared radiation through the lens. The control circuit is configured to determine the direction of crossing of individuals passing in front of the sensor device based on sensor signals from the passive infrared sensor.
