P. Loslever, CONSIDERING IMPERFECTIONS USING 3D IMAGING-SYSTEM IN ANGLE OBTAINING,ANGLE SIGNAL DISTANCE COMPUTING AND MULTIVARIATE DISTANCE GRAPHING, Computer methods and programs in biomedicine, 47(3), 1995, pp. 197-204
Fields such as medicine, biomechanics or ergonomics need to measure th
e positions and the rotational movements of body segments. The aim of
this article is to underscore the problem of imperfection on angle mea
surement using a three-dimensional television system. First, the error
on a single angle value is assessed through the classical Taylor's fo
rmula and through a simulating approach. Then the error is considered
for an entire signal through either an experimental signals, a specifi
c coding technique is suggested. Finally, two graphical pattern are pr
oposed th show globally the distance between the signals with regard t
o the error.
