A STUDY ON SPATIAL INFORMATION ACQUISITION USING MULTI-SENSOR DATA REGISTRATION - FOCUSED ON WATERSIDE STRUCTURE

摘要

Since rivers have complex functions such as water use, flood control, water-friendly and environment, systematic management is essential. Particularly, it is very important to monitor the wind erosion and corrosion phenomenon for the management because water and strong winds often cause them. Recently, spatial information acquisition of waterfront structures using various platforms is being studied. The use of multi-sensors will be a great help in obtaining efficient spatial information. Therefore, in this study, we will perform a comparative study on the registration method of data acquired by multi-sensors for the utilization evaluation of spatial information acquisition for a waterfront structure. For this purpose, data from the terrestrial LiDAR and unmanned aerial vehicle were used, and study area is the lopbo of Yeosu, Gyeonggi-do, Korea. Point-based similarity transformations, and shape-based ICP algorithms were used.
