With the advances in computer technology and the changing needs of people&rsquo / s daily
lives, robots start to offer alternative solutions. As one of these solutions, the branch
of humanoid robots emerged as advanced robots that can interact with people. Robot
faces are one of the most effective means of interacting with people / since they can
express their emotions and reactions through facial mimics. However, the
development of realistic robot faces necessitates the knowledge of the trajectories and
displacements of actual face mimics.
In this study, a setup (both hardware and software), that can be used for tracking
critical points on human face while exhibiting mimics, is developed. From the
outputs of this setup, the mimic trajectories are going to be extracted. The setup is
designed and manufactured to be durable to external effects so that with a single
camera calibration procedure the 3D reconstruction can be carried out several times.
The setup consists of two webcams that are specially oriented for mimic tracking.
The images taken from the cameras are corrected / their features are extracted using
image processing algorithms / the centroids of the features are found / correspondence
is carried out and the reconstruction is made. This system can also be used for any
special point tracking or volumetric measurement purposes.
