Abstract

This document reports on the test results of an evaluation of the image quality of thermal imaging cameras used by the fire service. The test methods used were based on the test methods included in Draft NFPA 1801 Standard on Thermal Imagers for the Fire Service. The tests performed measured the nonuniformity, spatial resolution, effective temperature range, and thermal sensitivity of fire service thermal imagers. Images used for the evaluation were collected using a high-resolution visible camera focused on the thermal imager's display while the thermal imager viewed a variety of thermal targets. The laboratory test results were evaluated in terms of a multi-variate model of human perception, which was based on tests conducted on firefighters viewing thermal images of scenes in which a fire hazard may be present.
