Subject: JOB: postdoc in multiple-camera reconstruction



Two-year post-doctoral research position in multiple-camera reconstruction
Contact person: Radu Patrice HORAUD <Radu.Horaud at inria.fr>

The PERCEPTION group has recently started a multi-year collaboration 
with the Samsung Advanced Institute of Technology, Seoul, South Korea. 

Within this research project, PERCEPTION develops methods and 
algorithms for the visual reconstruction of a complex scene using a 
mixed camera system. The camera system is composed of four units; each 
unit comprises one time-of-flight (TOF) low-resolution camera and two 
high- resolution color cameras, a TOF-stereo sensor. The system is 
able to acquire finely synchronized multiple videos at 30 frames/
second. We already developed a method for calibrating each TOF-stereo 
unit [1] as well as a method  for calibrating the whole camera system. 

We also developed a reconstruction method that starts with the 3D data 
provided by the four TOF cameras, followed by mesh refinement and 
rendering using the eight color cameras and based on the mesh-
evolution method described in [2].

The post-doctoral researcher will further continue to explore the 
potential of such a mixed camera system. In particular he/she will 
investigate how to combine classical stereoscopic vision algorithms 
with the TOF sensors in order to obtain a high resolution dense depth 
map - depth data upsampling. He/she will also investigate how to fuse 
TOF-data with stereo-data in order to deal with situations where depth 
cameras alone or color cameras alone are unable to provide accurate/
dense depth maps, e.g., scattering surfaces, non-Lambertian surfaces, 
uniformly colored surfaces (no texture), bad lighting conditions, etc.

The expected outcomes of this research project are: scientific 
publications, patent applications jointly with Samsung, and software 
packages to be delivered to Samsung.
