AI Technical Summary
Technical Problem
The existing method for estimating the temperature of a pedestrian using the intensity of far-infrared rays detected by a far-infrared camera is inaccurate due to the non-constant relationship between the road surface temperature and pedestrian temperature.
Method used
A system that captures far-infrared images and uses reference objects at predetermined temperatures to estimate subject temperature, incorporating subject distance information and the absorption coefficient of far-infrared light caused by the atmosphere.
Benefits of technology
This approach allows for accurate estimation of subject temperature, improving the accuracy of pedestrian detection in far-infrared imaging systems.

Abstract
To estimate information on the temperature of a subject with high accuracy.SOLUTION: A system picks up, by an imaging unit 13, a far-infrared image of a subject, acquires subject distance information that is the distance to the subject included within an imaging range of the imaging unit 13, and estimates information on the temperature of the subject based on the subject distance information.SELECTED DRAWING: Figure 1
