Laser 3D scanning of architectural monuments

Abstract

Purpose: Summarizing the experience in laser 3D scanning of real construction sites relating to architectural monuments. Methodology: Data collection and processing of the point cloud formation of a building during the survey. Analysis of the work stages of threedimensional scanning, including photogrammetry with DJI Mavic 3 UAV and laser scanning provided by a Faro Focus S150 scanner. Research findings : Technical recommendations are given to laser 3D scanning of buildings. The formation stages of the point cloud of buildings are considered with identification of the key factors affecting the scanning objects. The proposed developments can serve as the basis for creating a full-fledged methodology for laser 3D scanning of construction objects in the future. Originality: During building restoration and their adaptation to modern conditions, it is important to obtain complete and reliable data on the building examination. It is important to record the most complete range of geometric parameters of the object, that improves the quality of restoration.
