Title:
TEMPERATURE ESTIMATING DEVICE, TEMPERATURE ESTIMATING METHOD, AND TEMPERATURE ESTIMATING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/095630
Kind Code:
A1
Abstract:
A temperature estimating device (100) is provided with: an acquiring unit (131) for acquiring a captured image captured using an image capturing unit (110) including an infrared light sensor and a housing; a generating unit (132) for generating a corrected image of the captured image by correcting the captured image using a correction parameter calculated by temperature calibration of the image capturing unit (110), performed in advance, and a provisionally set temperature of the housing; and an estimating unit (135) for estimating the temperature of the housing on the basis of the non-uniformity of a brightness value of pixels contained in the corrected image.
