A concept for applying VR and AR technologies to support efficient 3D non-contact model digitalization

In this paper a new interactive digitization concept for large real world objects is described using the virtual reality (VR) environment Elbe Dom. The method combines augmented reality (AR) technologies with a high quality display of textured three dimensional (3D) models. One focus is thereby the display of valuable information of the actual measuring process. The proposed method is a non-contact technique, especially applicable to objects with freeform and a size up to 5 m × 5 m × 3 m. The method achieves an accuracy value of less than 1 mm within the whole measuring volume.
