Utilization of a UAS-Lidar system for oil spill response in arctic regions
SessionMeet the Poster Authors
DescriptionConventional remote sensing including visual, multispectral, and thermal technologies has been widely used for UAS oil spill response operations. In this case we explore the utilization of Lidar mounted on UAS to detect oil targets of various thicknesses at day and night, and for the first time, we were also able to deploy and acquire data from a UAS-Lidar system from a moving vessel (USCG icebreaker SPAR) while navigating and breaking ice on the Great Lakes during the winter of 2023.
The controlled oil thickness targets were setup on an array of small containers on the ground (plastic totes) at the Lake Superior State University. The array consisted on oil samples ranging from 50um to 5000um of thicknesses. UAS-Lidar data was obtained at various temperature ranges and illumination conditions (during day and night). Initial results shows a relative correlation of both reflectivity and laser intensity with the increments of floating oil. Quasi-synchronous acquisition of UAS visual and thermal data allows to analyze and compare results from the lidar versus the RGB and thermal imagery. On this case the UAS-Lidar system consisted of an infrared laser, and these results are being also compared with visual Lidar systems from previous experiments.
