Swing analysis system using motion sensor, swing analysis method, and swing analysis program

摘要

PROBLEM TO BE SOLVED: To provide a swing analysis system which can obtain more accurate results by considering individual differences in individuals and sensors, a swing analysis method, and a swing analysis program.SOLUTION: A swing analysis system comprises a motion sensor attached to a subject of swing analysis, and a terminal device which can perform radio communication with the motion sensor. The terminal device comprises a swing data analysis part for performing swing analysis based on sensor data output from the motion sensor, and an error correction part for correcting output error of the motion sensor. The error correction part estimates the output error of the motion sensor by obtaining a difference between a coordinate point at the time of address of the subject and a coordinate point at the time of impact on the basis of the sensor data output from the motion sensor, and performs recalculation of the sensor data output from the motion sensor by using the estimated error.SELECTED DRAWING: Figure 1
