Fine Surveying and 3D Modeling Approach for Wooden Ancient Architecture via Multiple Laser Scanner Integration

A groundbreaking approach using multiple terrestrial laser scanners (TLS) achieves unprecedented accuracy—within 3 mm—in surveying and 3D modeling of ancient wooden architecture, even in challenging, steep terrains like the Wudang Mountains. This method overcomes traditional limitations such as mutual sheltering and scanning view restrictions by integrating three-level TLS with scalable measurement capabilities. The study introduces a multi-scale data fusion technique for precise registration and filtering of complex architectural structures, enabling the generation of detailed drawings (plans, facades, sections) and 3D models. These advancements facilitate deformation analysis and digital preservation, setting a new standard for high-precision documentation of heritage sites.
