3. Motion measurement errors

3.1 Instrumental errors

In the case of motion analysis systems using optical capture, instrumental errors correspond to the errors with which the three-dimensional positions of passive markers are reconstructed in the laboratory's global reference frame, which are due to the opto-electronic system itself. These instrumental errors are of two types . On the one hand, systematic errors depend on the validity of the model chosen to define the cameras, and on the precision with which the parameters...
