Contribution of the Temperature of the Objects to the Problem of Thermal Imaging Focusing

TL;DR

This paper investigates how the temperature of objects affects the focusing process in thermal imaging, revealing that temperature significantly influences focus quality in the infrared spectrum.

Contribution

It introduces the novel insight that object temperature impacts thermal focus, an aspect previously underexplored in thermal imaging research.

Findings

Object temperature affects thermal focus quality.

Thermal focusing depends on object temperature.

Experimental evidence supports temperature's role in thermal imaging focus.

Abstract

When focusing an image, depth of field, aperture and distance from the camera to the object, must be taking into account, both, in visible and in infrared spectrum. Our experiments reveal that in addition, the focusing problem in thermal spectrum is also hardly dependent of the temperature of the object itself (and/or the scene).
