Abstract
The Transylvanian region of Romania is a place of rich history since ancient times, where the original natural environment around architectural heritage sites or buildings has not been severely altered by urban development. Unfortunately, many such places are left by the authorities to degrade or totally collapse for lack of funds, vision or initiatives. The current paper addresses the potential of Unmanned Aerial Vehicles (UAVs) in the assessment of a viable and feasible prospect of restoration on a 19th century mansion that belonged to a nobiliary family. UAV use is rising in many industries and has become very popular in the last decade, but for survey engineering and related domains they represent a quantum leap in technology. Integrating UAV-acquired data and structure from motion software, has enabled modern techniques to obtain useful metrics from the field, accurate photorealistic 3D models for visual inspection, structural damage analyses, architectural rehabilitation-restoration, conservation and spatial analysis of the surrounding area. In this work a socio-cultural planning and design process is explored and presented to improve the local community and inclusion in a tourist circuit based on the regional potential, as well as an evaluation of accessibility derived from a vector-raster database that highlights the central position of the cultural heritage in regards to the axis of circulation between the important metropolitan areas and the local tourist attractions. This established workflow of modern topographic and construction measurements is fully integrable into the architectural process, building information modelling, heritage conservation and reconstruction.
Highlights
In the field of architectural documentation and cultural heritage as well as numerous other disciplines and industries, Unmanned Aerial Vehicle (UAV) imaging and data acquisition has developed rapidly, facilitating compelling advancements in documentation and analysis throughout three-dimensional (3D) modelling and spatial analysis used for preservation and management of cultural heritage sites [1,2]
The current paper addresses the potential of UAVs in order to analyze, inspect and interpret, conserve and manage cultural heritage data through a case study of a 19th century mansion situated in Sălaj County (Transylvania Region, Romania) that belonged to the Hatfaludy family
Sălaj County is situated in the Transylvania region, in the northwest of Romania (Figure 1), at the cross between the Eastern Carpathians and the Apuseni Mountains
Summary
In the field of architectural documentation and cultural heritage as well as numerous other disciplines and industries, Unmanned Aerial Vehicle (UAV) imaging and data acquisition has developed rapidly, facilitating compelling advancements in documentation and analysis throughout three-dimensional (3D) modelling and spatial analysis used for preservation and management of cultural heritage sites [1,2]. The accessible instruments and techniques create high-quality results for 3D reconstruction and have become frequent practice for recording historical or cultural heritage objects. Photogrammetry applications have a long history of successful achievements in 3D recording and architectural documentation [4,5]. Photogrammetry techniques based on drones equipped with a digital camera have become some of the most promising and practiced techniques in last years. Factors explaining the popularity of UAV-based surveys are the efficiency of acquisition data on heritage sites of all sizes, the relatively cheap operational expenses, the rapidly captured high-resolution images and overall maneuverability in all terrain conditions [6,7,8]. The implementation of UAVs opens various new interdisciplinary applications and research directions and has become progressively common due to the considerable potential in terms of accuracy, cost and abilities [7,9,10]
