Estimation of golf club's loci and attitudes using 3-axis acceleration sensor

摘要

In this paper, we propose an estimation method of golf club's loci and attitudes using a 3-axis acceleration sensor¹. Extraction of golf club's loci and attitudes from the 3-axis acceleration sensor is difficult. Because an output values of a 3-axis acceleration sensor are affected by gravity acceleration. For this reason, we use an appropriate golf swing model that describes relationships of golf swing properties. Based on the swing model, we estimate golf club's loci and attitudes that appropriative to the output of sensor. By applying the estimated golf club's loci and attitudes, we made a golf game. Using our estimation, we get advantages of lower cost and little constraints of location compared to other researches.
