AB - Artificial muscles are formed by attaching a conducting polymeric
film to a non-conducting one. Applying an electrical
current on the muscle. a macroscopic bending movement
appears on it. Study of curvature variations and related parameters,
such as speed of motion or energy of curvature,
is necessary for improving the efficiency of these devices.
In a previous work. a one-cam computer vision system was
developed to estimate motion parameters in 2D with precise
results. In this paper, a two-cam stereo vision system is proposed
to process the image sequence and track the muscle in
3D. Active contours models are employed in motion detection
and mechanical parameters estimation. Results prove
the validity of this approach, allowing automatic testing on
the research into artificial muscles.
