Integrated Architectural Survey Techniques for the Cultural Heritage Preservation and Enhancement in the Covid-Era. The Case Study of Venosa's Most Holy Trinity Complex, Italy

Acquiring the digital documentation of the Cultural Heritage buildings is a complex process, which varies considerably according to the nature of the artefact and the equipment used. Today it is possible to rely on several survey techniques that lead to the creation of a realistic 3D model, featuring a high metric quality and details in line with the geometric features of the object. The main goal of the present study is the development of a unified process using different architectural survey techniques, such as range-based and image-based techniques, as from the case study of Venosa's Most Holy Trinity Complex, in Potenza, Italy. In addition, the paper explores the potential of online virtualisation at 360 degrees of the architectural survey, being a contribute to the disciplinary knowledge and, at the same time, to remote tourism, thus overcoming the travel restrictions due to the necessity to preserve the environmental sustainability and cope with the outbreak of the COVID-19 pandemic.
