Abstract

The technology to assess this nation's local architectural legacy must be lightweight, effective, and adaptable. Economical drones and Structure-from-Motion (SM) methods can fulfill these requirements. Recent research utilizing nadir photos from economical drones and SM methods has demonstrated favorable metric outcomes (achieving centimeter-level precision) modeling two-dimensional items (properties, rooftops, and facades). Constructing a comprehensive 3D model of past buildings is highly desirable, necessitating a camera system capable of producing nadir and side views with varying starting points. The findings demonstrated that the drone-derived modeling is accurate for most measuring. The precision and thoroughness of the 3D model facilitated the execution of Historic Buildings Information Modeling (HBIM) and deformation of structures research. The information was amalgamated with geographic information (landscape and architecture), enabling visualization, administration, and assessment at a broader scale. Given the affordability, portability, and comprehensiveness of drone and SM, this instrument holds the potential for studying historical legacy.
