3D PITOTI – New Technologies for Rock Art Research
EU-funded Research Project
ArcTron 3D is part of a top-class consortium substantially funded by the EU in order to develop new technologies for rock art research.
The impressive rock art across the Valcamonica valley in Northern Italy is subject of the project. More than 100.000 single images are spread over the 70km long valley and date from the Chalcolithic to the Middle Ages.
„Rock art“ – images carved or pecked into stone – is more common in Europe than painted cave art. This art exists in open-air surfaces exposed to the weather rather than inside caves. This wealth of Europe’s cultural heritage is inaccessible, difficult to study but provides profound stories from our ancient past. These „Pitoti“ (meaning little puppet in the local dialect) have been UNESCO World Heritage since 1979 but are still are no very well known.
3D-Pitoti is going to change that: New technologies will be developed in order to replace old documentation methods. Together with innovative visualization techniques, they will not only spread the word of the Pitoti to a wider public, but also advance a new stage of scientific results.
At the beginning of the project, ArcTron 3D will record reference data at several levels with latest 3D scanning technologies: A complete 3D model of the valley will be created using airborne 3D photogrammetry, terrestrial laser scanning will survey whole rock formations, and single Pitoti will be recorded in highest resolution using structured light scanning.
During the project, ArcTron and TU Graz will develop a new, portable high-resolution scanning system for extremely flat structures. It will be subject to various field tests. All data recorded during the project will be integrated into a complex 3D information system. ArcTron’s long-term developments in that area will serve as a basis for that. The project will also develop intelligent algorithms that enable an automatic segmentation and classification of single Pitoti.
New interactive and stereoscopic visualization technologies by the Bauhaus University of Weimar will prepare the data not only for scientists but also for new didactic approaches to visitors and school classes.
3D-Pitoti is funded by the 7th Framework Programme of the EU and is carried out by the following partners:
The University of Nottingham
Fachhochschule St. Pölten Forschungs GmbH
The University of Cambridge
Technische Universität Graz
ArcTron 3D - Vermessungs- und Softwareentwicklungs GmbH

Bavarian 3D High Tech Specialist Involved In Swiss World-Premiere
3D documentation of the mysterious Chavín temple in the Peruvian highlands
A team of surveying engineers and an archaeologist from Bavaria took upon themselves the arduous journey across the Andes into a narrow mountain valley 3.200m high. Their destination was the temple complex of Chavín de Huántar with its mysterious stone sculptures. They brought along different 3D high tech surveying systems in order to document the UNESCO world heritage site in 3D. They were supported by archaeologists from Peru and Stanford University.
The engineers were accompanied by a Swiss TV team and the project leader Peter Fux of the Museum Rietberg. The complete 3D documentation of the ArcTron surveying team took less than 3 weeks. The greater part of work – data evaluation and processing of 3D data – will take more than half a year.
3D laser scanning data and lots of aerial images form the basis for various kinds of contents in the developing exhibition in Zurich (Museum Rietberg). Apart from terrestrial methods, a powerful octocopter and a motorized paraglider were deployed with 3D photogrammetry technologies.
The results were: spectacular aerial pictures and videos, panoramas, 3D models and 3D graphics, a monumental CNC-milled 1:1 replica of the 4m high statue ”Lanzón”, different multimedia installations, visualizations and a virtual reconstruction of the temple in a 15 minute 3D documentary in the museum cinema.
Time is running: on November 22nd, the exhibition is launched with a world premiere of this exciting pre-historical Peruvian culture from 1200-500 BC. The Rietberg-Museum in Zurich has taken on the task of researching and preserving this culture. It displays the first Chavín exhibition ever with latest archaeological discoveries from Peru.
With help of the millimeter precision of latest 3D technologies, ArcTron documents the complete temple in high accuracy. Single objects of national Peruvian importance, like the Tello obelisk, the monumental Lanzón cult statue and some Chavín reliefs were even scanned with submillimeter accuracy.
The documentation work for the complex 3D project was carried out by ArcTron 3D GmbH from Regensburg in the spring of 2012. The project is commissioned and supported by the Rietberg Museum Zurich.
For almost 20 years now, the cultural heritage specialists of ArcTron 3D GmbH have been realizing projects in archaeology, surveying of cultural goods and terrestrial as well as airborne 3D laser scanning worldwide. „Such extraordinary museum projects are a fascinating and enriching experience for our work“, says Martin Schaich, CEO of ArcTron and an archaeologist himself.

aSPECT3D - 3D scanning, measuring, modelling & structuring based on compact camera pictures?
Digital 3D models simplify the work of engineers, architects, designers or cultural heritage preservers on many levels. 3D data is also essential for the industrial sector. The problem with 3D data often lies within the data collection: how are you supposed to obtain 3D data when deadlines and budgets are pressing and 3D scanners and surveying services are not an option?
Generating 3D models - using your own camera and the right software solution
The software aSPECT3D enables every user to generate 3D point clouds of an object from digital image series. This process requires nothing but a commercially available digital camera. The user needs to document the object with a large number of images from various perspectives. From these pictures, aSPECT3D computes the 3D point cloud, which can afterwards be scaled and transformed into the desired coordinate system. For that, you can combine and correlate the point cloud with data of other survey systems (e.g. a simple length measurement, total station, GPS, 3D laser scanner, 3D structured light scanner). Furthermore, aSPECT3D offers various functions for triangulation and texturing of recorded objects.
How can large 3D survey data amounts be structured and managed?
The inherent, revised and redesigned PostgreSQL-database can store, manage and structure all data (geometries, textures, points, meta data). The database can individually be modified and built up by every user and thus offers great flexibility. 3D data sets imported into the database can be further segmented, categorized and combined with additional meta data (PDFs, films, texts, images).
A new presentation module provides a fast and efficient display of your point clouds and 3D objects in high-resolution graphics or animated videos.
The latest aSPECT3D version provides users with an extensive 3D tool set. It can combine and edit data from different survey systems and manage it in an individually configurable database. A new age of 3D documentation and presentation is rising: Generating 3D models with or without 3D laser scanner – Visitors can experience this hands-on also at our exhibition shows.

May 2011 - a gift for the US President Barack Obama
US President Barack Obama received the 3D model of the Durrow High Cross carved by laser into a solid block of chrystal, produced by ArcTron 3D.
Among other outstanding Irish monuments ArcTron3D documented the 3.8-meter-high cross with scanning technology back in 2009.
