Abstract
An innovative approach is shown that can allow
search-and-rescue personnel to find survivors trapped in fire scenarios
through active laser scanning. This new but simple imaging technique
permits to see live people through a flame wall by portable system
suitable for on-field applications. Combining IR laser raster scanning
with a bandpass frequency filter and an IR camera, we show that a
direct useful signature of a scattered human target can be detected
while discarding the flame emission. Several experiments are reported
also by using a cheap, light-weight and low-resolution camera to demonstrate
that the proposed approach allows real-time operation by portable
light-weight device, thus being useful in the hands of firefighters.
