A portable LIDAR system for the early detection: FfED system - a case study.

摘要

Forest fires can be the cause of serious environmental and economic damage. For this reason considerable effort has been devoted to forest protection and fire-fighting. Experimental and theoretical investigations have already shown that the LIDAR (Light Detection and Ranging) technique is a powerful tool to detect the tenuous smoke plumes produced by forest fires at an early stage In this paper the capability of a LIDAR system to detect a forest fire is explained and an upgrade of the LIDAR technique to reduce the number of false alarms is described. It is based on the comparison between the backscattered signal due to the orography, acquired in absence of any fire, and the signal obtained during surveying. The first experimental results, acquired by FfED (Forest fire Early Detection) system, will be shown.
