The range of application for Scanners and Processing

The 4 Project I mention in the following are done with 3 different techniques and typs of Scanners.
1. Laserscanning of 3200 Dinoaursteps on a wall in Bolivia, Sucre Mai 2006
On the surface of a wall, which is 120 m high and 1200 m long there are about 3200 different Dinosaur foodtraces. The biggest steps have a diagonal of 70 cm. The accurancy of scanning this wall is about 1 -2 cm, which arises from a distance about 100 m to the wall. There we put the Scanner to generate the Modell for the Orthophoto on the one hand and an UMK-Kamera with a picture size of 13×18 cm to generate the plan in Scale 1:100 with a dpi-resolution of 300 dpi on this scale on the other hand. The Orthophoto and the 3D-Model are basic for the Researchgroups which are working in the field. Photo of the wall Surce/Bolivia (Linsinger)
2. Closerange Scan of 200 Figurines in a Temple in Xian/China, (Nov. 2005 till July 2006)
For this project I am not allowed to show any Pictures we have done and also no Scans because of the privacy of this project. This is only allowed if I have a permission from the Foundations who paid the project and the official office from China and our Partners in the US.
The whole temple has about 4.500 Figurines. In one month we have done 2/3 of one wall with about 200 Figurines with 2.700 single Scans.
To capture the Figurines in an accuracy of 0,1 mm – 0,4 mm was very hard done because of the location on the wall. Each Figurine is linked with each other. The distance form the Scanner to the objects were in average 1 m. The texture for the 3D-Modell is generated with a Camera with 16 Mio. Pixel.
For the whole Temple our Partners form the Universities in the US were using a Haselblatt with 39 Mio. Pixel to capture the whole inside of this temple.

3. Closerange Scan in combination with a FaroArm in the Cuviellies-Theatre in Munich/Germany, Mai 2006 – Juni 2008.
This project was an European proposal in Januray 2006. The aim of the project is to scan the whole theatre in an accuracy of 0,4 mm and a visualisation of the whole theatre. For this project we are using two different techniques. At first a close range Scanner from Breuckmann/Germany that provides about 70% of the data for generation and for the last 30% we are using a FaroArm from the company Faro.
The time to capture only the 3D data will take about 1 year inside the theatre and about 3 years in office.
