Advanced digital mapping tools and technologies are enablers for effective e-planning in the built and human environment. The regeneration and transformation of cities from the industrial age to the knowledge age is essentially a ‘whole life cycle’ process consisting of; planning, development, operation, reuse and renewal. The use of the 3D laser scanner enables digital documentation of buildin...

The synthesis of controller algorithm for reversible electromechanical scanner of the telescope scanning axis is discussed. Digital control system is built without intermediate stage of synthesis of analog control law. The modified procedure for the synthesis of discrete optimal control law is introduced. Elasticity influence on static and dynamic characteristics of electromechanical scanner of...

A method based on extracted trunks is proposed for automatic determination of corresponding trees between a georeferenced pair of terrestrial images and airborne laser scanner data in a wooded area. Trunks in the terrestrial images are obtained by region growing segmentation between left and right edges of trunks detected within a region of interest. Trunks in a digital tree height model genera...

A scanning device generally referred to as a "laser scanner", used to obtain 3D data of objects by irradiating laser beams, is used in the field of cultural properties, and is starting to achieve significant results. The technique to record complex 3D data with high accuracy and speed, without touching or destructing an object, makes it an essential tool in the field of cultural properties, as ...

PURPOSE To obtain an accurate CAD/CAM metal framework over 6 implants using a Chairside Intraoral Scanner based on the principle of active (optical) wavefront sampling. MATERIAL AND METHODS Six prototype cylindrical scan bodies screwed in the implants were used to obtain an intraoral digital impression. A conventional resin tooth try-in was fabricated and digitized with an extraoral scanner, ...

DETECHIP ® is a molecular sensing array used for identification of a large variety of substances. Previous methodology for the analysis of DETECHIP ® used human vision to distinguish color changes induced by the presence of the analyte of interest. This paper describes several analysis techniques using digital images of DETECHIP ® . Both a digital camera and flatbed desktop photo scanner were u...

A scanner characterization method based on an analytic spectral model was derived. Themethod firstmodeled the spectral formation of eachmedium using either Beer-Bouguer Law or Kubelka-Munk theory. Scanner digital counts were then empirically related to dye concentrations. From these estimated dye concentrations, either spectral transmittance or spectral reflectance factor could be predicted. Th...

This project presents a digitizing process of 3D laser scanner for culture heritage. The experimental records are mainly for systematic 3D model reconstruction and digital archiving of historical scenes. The procedures of digital heritage are 3D data acquisition, 3D modelling and web-based representation which demonstrate the reconstructed results and the application of virtual scene.

Digital impressions can be a useful option that reduces patient discomfort and simplifies clinical procedures such as accurate impression recordings. In this report, a patient with a partial maxillectomy was managed with a metal frame fabricated from a digital impression through an intraoral scanner. The final impression employed the altered cast technique for the fabrication of the obturator.
