We are recording a normal walking trial,we use qualysis
system(6 cameras)our marker setting method is 6 DOF, and we use V3D for
conducting our analysis.
1)Is it necessary to align the segment coordinate systems
with each other in a way that in the standing trial the angles show zero? Does
not the system suppose the angles of the static trial as the ziro position
for analyzing the motion trial?
2) the
results were far from expectations.(eg. Acceleration, picture1) whats
