Abstract

Terrestrial Laser Scanning (TLS) is becoming increasingly important in the cultural heritage field given the need for virtual records of buildings and detecting surface wear and deterioration. Scientific research has shown that exhaustive 3D modelling from point clouds enables accurate analysis of heritage buildings and sites. However, factors such as the number and location of scanning stations, distance to objects, point of view, and resolution impact the scanning and modelling accuracies. Through the case study of a 19th-century Anglican masonry church in Nottingham (UK), this chapter investigates the accuracy of TLS surveying features to model surface deficiencies in heritage buildings. The results showed that combining different points of view and distances can enhance accuracy, but the joint accuracy is still lower than that of the less unfavourable station. The research also determined the suitable meshing smoothening for damage modelling and analysed the point cloud discretisation distortion for accuracy analysis.
