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: An infrared sensor uses an infrared lens with infrared filtering and focusing functions. Thus, an infrared filter can be omitted to reduce the costs and volume. In addition, a getter on the inside of a metal cover of the infrared sensor can be activated when the metal cover is soldered to the substrate of the infrared sensor. Therefore, the packaging process of the infrared sensor can be simplified.

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.

Abstract: Apparatus and methods are disclosed for highly accurate remote measurement of sea surface skin temperature. Thermal band 8 to 14 micron images of the surface of the ocean taken by a downward looking infrared camera are processed to determine the optimum segments of the image to utilize. The influence of contaminating reflection of the downwelling flux from the sky and other error sources are removed and from the data and/or otherwise corrected for making sea surface temperature accuracy within several tenths of a degree possible.

Abstract: A method of measuring temperature based upon a system of equations applying Stefan-Boltzmann's law and using a measurement value for an object to be measured and an ambient temperature value (Ta) comprises: pre-calculating (200, 202) a first vector (LUT1) and a second vector (LUT2). The first vector (LUT1) is a series of values proportional to received power based upon respective temperature values and in respect of a predetermined generic range of temperatures. The second vector (LUT2) is a series of sensitivity characteristic factor values based upon expected measured temperature values and in respect of a predetermined range of expected object measured temperatures. The first vector (LUT1) and the second vector (LUT2) are used (206) to generate a temporary vector (LUTT) of a series of values limited to the ambient temperature value to solve the system of equations in respect of the measurement value for the object, thereby determining (208) a temperature (To) for the object from the measurement value.
