A well-defined methodology for data extraction, modelling, and monitoring is yet to evolve. This study compares and demonstrates terrestrial laser scanning and drone survey for building mapping with validation and accuracy checks. A terrestrial scanner was used to perform three scans of a building and drone was used to capture high-performance vertical images and oblique images. A three dimensional (3D) model was generated using advanced software techniques. Building facade elevation and plans were extracted from the 3D model after validation and accuracy check. The drone model produced high-quality visualization while terrestrial scanner output data allowed to extracting minute details after removing noise....

One of the methods to do an inspection is using a terrestrial laser scanner. This paper mainly focuses on studying the methodology for inspecting the bridges using a terrestrial laser scanner and Augmented Reality technology. In this paper, Laser scanning data was used to prepare Bridge Information Model and that model was further processed in Unity to create an Augmented Reality model. All this requires various data processing and post-processing. With the help of this model, one can do bridge inspection at the comfort of the office and reaching those inaccessible areas which are not possible to reach with traditional methods. This paper focuses on finding a different method or approach to do Bridge Information Modeling and get data of bridges for maintenance ...
