The scan 3D of Lighthouse gives life to the façade of the famous hotel Adlon in the Door of Brandemburgo

Lighthouse, world-wide specialist in portable solutions of measurement and capture of images, has given life to the façade of the famous hotel Adlon, in the Door of Brandemburgo (Berlin), thanks to the help of one of his more innovative products: the laser scanner Lighthouse Focus3D.

During the Festival of the Lights, spectacular animations and installations of lights light some of the historical buildings of Berlin. With two million visitors, the festival has turned into an important economic event. And the companies are conscious of the promotional value of the animations. In 2012, Volkswagen used the façade of the hotel Adlon like bottom for an impressesive promotional animation. And in 2013, again, the hotel served of surface of projection of a three-dimensional animation in video of VW.

To prepare the event and can integrate the grid of the façade and his structures in the videoinstalación, the artists needed a model of precise three-dimensional surface to a scale of 1:10. The laser scanner Lighthouse Focus3D supplied the necessary digital data for the exact modelling of the façade of the hotel in few hours. The work of inspection developed of night to minimise the annoyances in the activity of the hotel and the traffic. They took three escaneos from the roof of the building of in front to a distance of 60 metres of the Adlon; other six escaneos from the shod to some 30 metres of distance; and other six to 10 metres of the façade. “With 15 escaneos to high resolution generate some 2.400 million coordinates of measurement”, explains Lars Sörensen, director manager of the company of quality consultancy berlinesa Scan3D. “More than sufficient for mapear all the details of the façade with accuracy”.

Afterwards, the data of scan mattered directly to the application LupoScan, where each scan referenció using the objective marks. To continuation, the analysts employed the application ‘Rhinoceros' for modelar the surface of the façade. “This was necessary because, given the location, could not use a fork elevador to position the scanner”, declares Sörensen. Like this it created a model of digital surface extremely exact that the creator of the model used. With the help of the model 1:10, the videoartistas could project the animation 3D with precision on the structure of the façade and focus the proyectores with accuracy to the façade of the hotel.

The laser scanner Lighthouse Focus3D is one of the more vanguardistas of the market of the moment. With him, the buildings and his elements can turn into exact digital models in three dimensions. This compact and easy device to use scan all the visible structures of the building of an alone past and afterwards creates an exact three-dimensional model. When generating around one million points of measurement by second, the big objects and his surfaces can capture to the detail, in high resolution and even in colour. The process results ideal to analyse faã§ades, for example. The time and the cost to measure the grid of the façade and the structures associated reduce to the minimum with the laser scanner, by what, for example, is not necessary to mount expensive andamiajes. East was the process used in the Festival of the Lights of Berlin, like preparatory measure for this video that projected on the façade of the hotel Adlon and that it was all a success.
