Accuracy improvement in 3D measurement with commercial cameras

In this paper, a procedure for acquisition and processing of the human locomotion system kinematics data is given. Software for 3D motion analysis system has been developed. Data aquisition was done using two commercial video cameras (camcorders), framegrabber and PC. Data processing by direct linear transformation provided 3D co-ordinates of the measured movement. System accuracy, regarding error due relatively low frame rate and non-synchronised cameras, was improved using software. The procedure for synchronisation error elimination will be described in detail.
