Design of Motion Analysis Software for Walking and Running

The purpose of this study was design software for biomechanics analysis walking and running in different velocities and to survey kinematics and kinetics parameters using a novel approach in human motion tracking. Twelve men selected with average age 26.80<3.68 years, weight 66.90±8.21 and height 1.70±0.04 and installed markers on their joints. Subjects walked and run on treadmill with 1.5,3.5,6,8, 10, and 12 KmIh. The proposed method is developed to capture markers positions associated with human motion obtained from video data. That captured with speed 250 frames per sec and in two synchronal sagittal and fronlal planes. A data-driven predictor is used for tracking of wearing reflective markers. The uncertainty and occlusion of detected markers increase the noise in captured positions. For solving these problems, we proposed a suitable approach which includes a memory based data-driven system. The result of tracking algorithm is tested more than 30000 captured frames. Results were validated, This software could easily biomechanics analysis walking and running in using simulation approach at different velocities and calculated kinematics and kinetics parameters in two plans, as well sagittal and frontal, too.
