RESUMO
The purpose of this study was investigate the measurement techniques of human movement and to develop a system capable of capturing and reconstructing the movement trajectory on real world. The devised system uses video cameras to record the movement and a computer program to process video footage assessing the movement trajectory and calculating its kinematical variables. Those data are showed by the program as graphics or animation which simulates the reconstructed movement. To reach these objectives, the system used techniques from image processing, computer vision and anthropometric models. In the end of this work, it is exhibited an experimental evaluation of the precision and accuracy of the system and some case studies to show its potential.
