Digitalização 3D do patrimônio arqueológico metálico utilizando o Kinect

Abstract

The archaeological heritage are fundamental for the construction of the cultural identity of a society, contributing to recovery the history and the memory de social groups. The preservation of these artifacts is a duty of contemporary society, because promotes your development for future generations. Currently there are many 3D reconstruction techniques and devices that are capable of performing 3D representation of a real object. In archeology, it is a major breakthrough because it excludes the use of traditional techniques of plaster molding, which can compromise the integrity of artifacts. The interest in the use for 3D data acquisition techniques in archeology have been increasing significantly in recent years. The availability of depth sensors based on light structured on the market demonstrates several new opportunities in the preservation of cultural heritage. This work investigates the use of an effective and economical method to perform 3D reconstructions using data acquired by the Kinect sensor. These data can be used to create and disseminate digital replicas. Kinect has great potential because it has an affordable price compared to other sensors. Some technical difficulties have been overcome for the use of Kinect in this work. One of the main difficulties is the large amount of noise that Kinect returns on the clouds of points. The benefits and challenges of using Kinect will be measure. Also results will be presented showing that 3D modeling using the sensor is capable of creating archaeological artifacts replicas
