Motion analysis system for identification of 3D human locomotion kinematics data and accuracy testing
In this article, a procedure for acquisition and processing of the human locomotion system kinematics data is presented. Software for 3D motion analysis system is developed, discussed and described. Data acquisition was performed using two commercial camcorders, framegrabber and a personal computer. Data processing by direct linear transformation provided 3D co-ordinates of the measured movement. Inaccuracies due to the relatively low frame rate and non-synchronised cameras were improved using software. The results of laboratory testing are given, and confirm this improvement. The procedure for synchronisation error elimination is described in detail.
