Anthropometry Research Group Institute of Biomechanics

Technology

We develop specific 3D scanning technology to support innovative business models based on user anthropometry. They are specifically designed to use it at home or at the point of sale.

Smartphone scanning

Foot scanning app

A cutting-edge smartphone application which allows to capture the 3D shape of the foot with only three pictures and making possible to obtain the dimensions of the foot from any location.

This technology overcomes the main barriers to the massive spreading of foot scanners’ use to e-commerce, retail or new business models. So, the main advantages are:

  • It can be used on any smartphone, from any place, without additional hardware
  • Free App that can be downloaded from the App Store or Google Play
  • Pay-per-use (It is not necessary the investment in hardware)
  • Easy-to-use. Excellent accuracy for applications such as size allocation and made to measure footwear
  • Fast scanning process. Excellent user experience



Technology

Based on data-driven 3D reconstructions, using a mathematical model created from large 3D feet databases. The reconstruction algorithm finds the combination of shape parameters that best matches the silhouettes extracted from three pictures (lateral, front and medial) that can be taken by the user. The files are sent to a server that performs the 3D reconstruction of the foot. In less than two minutes the foot in 3D is displayed on the screen.

Whole body scanning app

A mobile application for capturing the 3D body shape with only two pictures.

  • the first image is a front photograph of the person standing with the arms and legs slightly separated from the body.
  • the second one is a lateral photograph with the arms stuck to the body.
 
 

Cutting-edge technology for easy and quick body scanning with a smartphone to support innovative business models based on user anthropometry:

  • It can be used on any smartphone, from any place, without additional hardware.
  • Excellent results for applications such as size allocation and made to measure clothes.
  • Easy-to-use.
  • Fast scanning process. Excellent user experience.



Technology

Mathematical body models developed from extensive databases allow the accurate 3D reconstruction of whole human body.

The image calibration process uses stature of the photographed person and parameters from the telephone such as the camera, gyroscope and accelerometer. Due to the variability of the backgrounds, clothing colours, and user posture, the adaptive silhouette is also used to support the segmentation algorithms.

In-shop foot scanner


Based on data-driven 3D reconstructions, DOMEScan/IBV is a low cost 3D foot scanner specially designed for retail.

Easy to use, quick and versatile, it provides automatically a 3D model and more than twenty foot measures.

DOMEScan/IBV is the best solution for in-shop foot scanning:

  • Easy installation and usability, no special knowledge about scanning is required.
  • Lightweight, easy-to-handle and wireless, it is easily portable.
  • Robust (no moving parts).
  • Excellent accuracy for applications such as size allocation and made to measure footwear.
  • Excellent user experience
  • Low cost with the possibility of pay-per-use.
  • The software allows the single and multiple exportation of data (foot measures and 3D models).
  • Possibility to generate and print a report with user data.
