IMUセンサを複数搭載した小型ブイによる波のパラメータ推定

抄録

High frequently measurement techniques of sea surface conditions are important for ocean science research, such as the construction of climate change models. We are developing a sea surface conditions measurement system using small buoys with multi-IMU sensors. The proposed system aims to improve accuracy with multiple IMU sensors and utilize wave periodicity to reduce integration errors. In this paper, we report the wave direction estimation method using a small buoy with two IMU sensors. The wave direction is estimated using the buoy motion compensation method which we are proposing. The wave direction estimated by the proposed method is compared with the motion capture data. Experimental results show that wave direction can be estimated by the proposed method.
