On Fabrication of a Shoe Insole: 3D Scanning Using a Smartphone
The generation of 3D models from still images has been a long term goal in computer vision. Acquiring high quality 3D models is no longer restricted to processing on desktop computers and high end laptops. Modern and powerful smartphones open up the possibilities designing new methods for 3D reconstruction. The scope of this work is the development of the prototype system on a smartphone for the efficient active stereo 3D reconstruction. Acquired 3D results are apparently no different from 3D results using a standard structured light scanner. Extending smartphone’s functionality towards an active stereo 3D scanning device is interesting both for the medical applications and for the industrial (economic) exploitation as well. Namely, combining 3D reconstruction capabilities with the present smartphone features sets the foundations for numerous other functionalities.
This work has been supported in part by Croatian Science Foundation’s funding of the project IP-11-2013-3717 and in part by Croatian-Chinese (Shenzhen Institutes of Advanced Technology (SIAT), Chinese Academy of Sciences, Shenzhen, China) bilateral project “Single shoot structured light 3D reconstruction”.
We are grateful to Polyclinic for physical rehabilitation and medicine Peharec (http://www.peharec.com/) from Pula, Croatia for providing us with a special type of foam needed to take the imprint of the patient’s sole.
We also thank Prof. Timo Götzelmann from Department of Computer Science, Nuremberg Institute of Technology, Germany, for providing us with the STL file utilized to 3D print an adapter used in this work.
