摘要：In this paper we report on our latest research work in capturing 3D geometrical information of heritage monuments. The work is illustrated through a case study from Tuscany, a small but spectacular Romanesque church close to the castle of San Giovanni d'Asso (Siena, Italy). Using terrestrial laser scanning (TLS) and image-based techniques we were able to create a complete 3D model of the interior and exterior of the church. The images were acquired with consumer-grade digital cameras (6 and 8 mega pixels) along with a small radio-controlled helicopter to capture details of the roof and the apse which was not visible from ground level. Decorations and small details were modeled in high-resolution with an automated image matching algorithm while the simpler geometries of the exterior were reconstructed through a semi-automated approach. TLS was employed for the interior of the church, which consists of a main floor above a very small crypt, the recording of which was complicated by a plethora of columns and arches. The 3D survey, representation and reconstruction of San Pietro in Villore should become a case study of scientific research addressed to test a simulation based open- space where it is possible in every moment to measure and compare historical evidence, stratigraphical relationship and other datasets but also where is possible to improve and upgrade the record in the future on the basis of new field work or post-processing
