Transfer of autonomous mapping concepts to a small uncrewed surface vehicle
No full textApproximately 70 % of the Earth’s surface is comprised of water, yet our understanding of its rivers, lakes and especially its oceans remain surprisingly limited. By employing state-of-the-art mapping technologies, uncrewed vessels can efficiently survey underwater terrain and gather valuable data, thereby reducing operational time and costs significantly. This paper examines the adaptation of autonomous mapping principles to a compact, uncrewed autonomous surface vessel (ASV), demonstrating practical applications for aquatic data gathering. Particular emphasis is placed on the bathymetry data obtained through the use of the ASV, exemplifying its potential to offer precise underwater terrain maps, which are indispensable for comprehensive environmental monitoring, authorities and scientific research. The results demonstrate successful multi-domain mapping of various inland water environments, including harbours and lakes, using a compact ASV equipped with algorithms from Fraunhofer IOSB’s Autonomy Toolbox (ATB). Additionally, the study achieved effective sensor fusion of geo-referenced LiDAR, sonar and camera data, providing a comprehensive hydrographic dataset for detailed environmental analysis. We find that autonomy functions of ASVs are already suitable for practical use; however, manual verification cannot be entirely eliminated yet
