ABSTRACT

The process of generation of geometric documentation is an important tasks in the field of conservation and management of cultural heritage objects. The 3D documentation is commonly used in conservation, restoration and analysis of historical objects and sites. The recent development of low-cost photography such as mobile phones, digital compact cameras or action cameras are now becoming dependable sources of data, which allow to create reliable and accurate documentation for different types of cultural heritage objects. The objective of this paper is to investigate the possibility of using the Xiaomi Yi 4K action camera for the documentation of frescoes through generation of orthoimages. The test field were frescoes in The Bieliński Palace in Otwock Wielki, near Warsaw (Poland), which is a great example of Late Baroque noble residence. A comparison was conducted using orthoimages from terrestrial laser scanner Z+F 5006h and the scale bars which were measured manually and were treated as reference data. This paper presents the results of the latest investigations carried out by the interdisciplinary team from three institutions: the Systems Research Institute PAS, The Department of Geodesy and Cartography of the Warsaw Technological University in association with the National Museum in Warsaw.

Keywords: low-cost camera, dense image matching, monumental objects, orthoimages, SfM
