Golf Swing Motion Tracking Using Inertial Sensors and a Stereo Camera
Cao Nguyen Khoa Nam,Hee Jun Kang,Young Soo Suh IEEE 2014 IEEE transactions on instrumentation and measureme Vol.63 No.4
<P>A golf swing motion tracking algorithm is proposed in which the golf club trajectory (position and velocity) and club face orientation information are given. Two sensors are used in the algorithm: an inertial sensor unit on the golf club, and a stereo camera that captures infrared light emitting diodes (LEDs), also on the golf club. During the address and impact golf swing phases, the camera captures the infrared LEDs on the golf club. Using the infrared LEDs as landmarks, the position and orientation of the golf club are computed. When the golf club is moving, an inertial navigation algorithm is used to compute the golf club trajectory. An indirect Kalman filter with nine states is used to combine the inertial sensor and vision data. The average position accuracy is about 3.6 cm and the maximum error is about 13.2 cm. The proposed system can be used to analyze golf swings quantitatively.</P>

3D Dynamics Analysis of a Golf Full Swing by Fusing Inertial Sensor and Vision data
Cao Nguyen Khoa Nam,Young Soo Suh,Dang Quoc Khanh 제어로봇시스템학회 2013 제어로봇시스템학회 국제학술대회 논문집 Vol.2013 No.10
In this paper, a golf swing motion tracking system is proposed, where golf club trajectory (position and velocity) and club face orientation information are given. Infrared LEDs and an inertial sensor unit are attached on a golf club and a stereo camera unit is used. During the address and impact golf swing phases, the cameras capture infrared LEDs on a golf club. Using infrared LEDs as landmarks, position and orientation of a golf club is computed. When a golf club is moving, an inertial navigation algorithm is used to compute the golf club trajectory. An indirect Kalman filter with 9 states is used to combine inertial sensor and vision data. The average position accuracy is about 3.6cm and the maximum error is about 13.2cm. The proposed system can be used to analyze the golf swing quantitatively.
