Terrestrial Laser Scanner Location and Path Planning on Construction Projects

Abstract

Recent advancements in Terrestrial Laser Scanning (TLS) have enabled reliable digital documentation of the built environment, supporting various construction engineering and management processes, such as infrastructure monitoring, cultural heritage documentation, and digital twin generation. As the demand for TLS on construction projects increases, it becomes increasingly more desirable to determine the minimum number of stations that maximizes coverage, and measurement accuracy. This paper discusses some of the existing approaches, including optimization strategies and metrics, to address the location planning of TLS using the digital model of the project. Finally, the results of select studies on a Benchmark 3D model was reported and discussed.
