An innovative hand-held vision-based digitizing system for 3D modelling

We describe a new hand-held 3D modelling device using vision and inertial measurements. Our system allows fast and accurate acquisition of the geometry and appearance information of any 3D object. We focused our work towards an easy manipulation and operating condition.Our methods allow automatic registration with no preparation of the scene (i.e. no markers) even when the object is moved between two acquisitions.In this paper, the design of the system and the developed methods for its use are presented. The system has been evaluated, qualitatively and quantitatively, using reference measurements provided by commercial scanning devices. The results show that this new hand-held scanning device is really competitive for modelling any 3D object.

► We present an innovative hand-held vision-based 3D digitizing system.
► The system needs no preparation (i.e. markers) and is automatic.
► We focused the design on easy handling.
► Target applications are retro-conception or nondestructive testing.
► Evaluation is performed using reference measurements provided by commercial scanning devices.
