3D image recording techniques are explored for documenting heritage objects, with a focus on low-cost and high-quality methods.

Abstract

espanolEl registro de imagenes 3D ha tenido un impacto creciente en el campo de los bienes culturales. Las aplicaciones incluyen la documentacion del estado de conservacion y de las dimensiones de un objeto, el estudio arqueologico de artefactos, la difusion de las colecciones de museos y sitios y el diseno de embalaje, entre otros. Las tecnicas de adquisicion de imagenes 3D comunmente mas usadas son el escaneo con laser y con luz estructurada y, cada vez mas, la fotogrametria digital de objeto cercano. En este trabajo, se presenta un estudio de caso de digitalizacion 3D para explorar las ventajas y posibilidades de la fotogrametria digital de objeto cercano respecto a las tecnicas de escaneo en documentacion de bienes culturales. Se probaron software gratuitos y de bajo costo y se analizo la calidad de los resultados obtenidos en cada caso. Tambien se discute la potencialidad de la fotogrametria digital de objeto cercano para optimizar la resolucion English3D image recording has reached an increasing impact on the field of cultural heritage. Applications include documentation of the state of conservation and dimensions of an object, the archaeological survey of artefacts, the dissemination of museum collections and sites, and packaging designing, among others. The 3D image acquisition techniques most commonly used are laser or structured light scanning and, increasingly, close range digital photogrammetry. In this work a 3D digitization casestudy is presented in order to explore the advantages and possibilities of close range digital photogrammetry respect to scanning techniques in documentation of heritage objects. Free and lowcost software used by these techniques were tested and the quality of the results obtained in each case is analyzed. The potentiality of close range digital photogrammetry to enhance the resolution of the 3D recording is also discussed.
