Il CNR ITABC è impegnato in due progetti internazionali di grande rilievo in collaborazione con i team delle università di Stanford e Berkeley (USA). Le attività del VHLab in Peru si configurano come indagini e rilievi sul campo con tecniche di mapping e modellazione tridimensionale.

CHAVIN
OBIETTIVI DEL PROGETTO
Il progetto intende realizzare un rilievo sistematico (con tecniche di mapping, DGPS, modellazione 3D) del sito di Chavin (Peru).

CHAVIN
THE PROJECT
The archaeological site of Chavín de Huántar, which lends its name to the rich Chavín culture said to originate there, is located in the highland region of Peru, about 250 km north of Lima.

The project's goal is the realisation of a sistematic survey (with mapping- DGPS and 3d modeling techniques) of the archaeological site of Chavin (Peru), using theodolite surveying technology and GPS; the team of Stanford University together with CNR ITABC is documenting the site topography, exterior architecture, and exterior sculptures.
The final product of the project will integrate all aspects of this research. A three-dimensional computer model based on exterior and interior architectural data will link with the virtual reality panoramas and video documentation for each area of the site. Together they will form a "virtual fieldsite" or "hypothesis tester," with which people can walk through a virtual Chavín, making observations, forming hypotheses about the construction of the site, its astronomical alignments, and yet-unknown aspects of the site, and then test them with the precise measuring capabilities of the site model.

TAMBO COLORADO:

Creazione di ambienti virtuali da dati Scanner Laser
Il progetto ha come obiettivo la ricerca e il rilievo sistematico del sito diTambo Colorado (centro amministrativo Inca del secolo XV) con tecniche di Scanner Laser e DGPS. Uno degli scopi fondamentali è la creazione di un archivio digitale tridimensionale del sito che include informazioni spaziali, fotografie digitali, dati topografici e architettonici, informazioni relative a materiali e texture. Il database andrà a formare la base per una ricostruzione virtuale e per una banca dati interrogabile in grado di contribuire alla conoscenza del sito e della sua architettura nel periodo in cui venne abitato, intorno al regno dell'Inca.

TAMBO COLORADO
Background
Tambo Colorado, located in the Pisco valley south of Lima, is the best preserved example of Inca architecture on the coast. It is famous for its decoration in vibrant colors: bright red, yellow and white (still well preserved and shown in the image opposite). The site is comprised of three main complexes which surround a large central plaza.

Virtual Environment Creation from Laser Scan Data at Tambo Colorado
This research investigates the use of laser scanning to obtain information about the built environment at Tambo Colorado, a 15th century Incan administrative center. A primary objective of this research is to create a digital repository for information about the site. This includes spatial information but also incorporates digital photography, survey data and textual information. This database will form the basis for virtual reconstruction work and the development of a database query system to help derive knowledge relating to the site's architecture and use during the reign of the Inca. This project web site offers some initial explorations of the data collected thus far and examines possibilities for dissemination of this information through various media.
