ABSTRACT
The investigation of the standardisation of 3D building modelling based on TLS (Terrestrial Laser Scanning) and MLS (Mobile Laser Scanning) point clouds aims at assessing the possibility of obtaining various levels of detail (LOD) in the context of performance, accuracy, and structure condition evaluation. The two point clouds represent a heritage church in Żmijowiska. TLS generates more detailed data, which supports higher LOD. This characteristic is critical for the precise representation of intricate architectural details and condition monitoring as it facilitates detecting deformations, damage, and signs of material degradation. Although less accurate, MLS offers substantial speed, cost, and hardware availability benefits. Effective and affordable scanning makes this method useful for regular monitoring of building and infrastructure conditions. Moreover, MLS cloud information can be enhanced with auxiliary data, such as images taken with mobile devices (smartphone or camera), to improve model detail and promote better structural evaluation. The results suggest that MLS is more suitable when rapid and cost-effective visualisation and monitoring are important. On the other hand, TLS is advantageous for more detailed reconstructions where high-quality data is required to diagnose infrastructure condition and create high-fidelity digital models of cultural heritage. Therefore, the technology should be chosen depending on the required level of detail and available resources because each offers unique benefits for specific types of projects.
