3D projection due to laser scanning
Title3D-Projektion mit Hilfe von Scannern visualisieren
Für eine 3D-Projektion auf das Modehaus Hirmer holte sich die Firma Mini Vegas aus Amsterdam Laserscanning-Technologie als Unterstützung. Das Ziel der Erfassung vor Ort war die Bestandsdokumentation, um die genaue Einstellung der einzelnen Projektoren zu bestimmen und diese synchron abstimmen zu können.
For a 3D projection on the fashion boutique Hirmer, the company Mini Vegas from Amsterdam got laser scanning technology for support. The goal of the scanning on site was the as-built-documentation for determining the exact setting of the single projectors and coordinating the projectors synchronously.
Scanning
By positioning the scanner at nine laser scanning locations, a total of 880 m² façade has been scanned for determining the main projection surface exactly. Furthermore, the entire surroundings have been registered for the additional documentation of the existing buildings. Due to the extensive documentation, distances and further possibilities for the projectors’ setup could be simulated. The structures and frescos of the main facade were of particular interest. Laser scanning presented the perfect measurement method for the highly accurate registration of all façade details.
Analysis and interpretation
Based on the measurement results, the layout has been generated automatically in Laserscanning Europe’s software PointCab. The point clouds have been processed to a mesh. Then, this mesh could be used for a 3D animation in Autodesk Maya.
Results
The results were impressive! At the premiere on May 16th, the passersby and interested parties could marvel at the 3D projection. Due to the comprehensive registration of the facade details and the surroundings, all required information which is required for the visual reprocessing and the 3D animation is available. This example shows that laser scanning is applicable in 3D visualization more and more.
