Application of BIM and UAV 3D reality modeling technology in highway engineering construction

The purpose of this study is to explore the integrated application of BIM and UAV 3D reality modeling technology in highway engineering construction. This paper introduces the core technology of 3D reality modeling based on UAV airborne LiDAR system, summarizes the integration process of 3D reality modeling technology and BIM technology, and conducts application research of BIM and 3D reality modeling integration technology in highway engineering construction based on practical projects. The results show that the original data collected by the airborne LiDAR can be processed by 3D reality modeling technology, and the 3D reality model with accurate plane and elevation coordinate information can be generated. The combination of BIM and UAV 3D reality modeling technology performs well in terms of data integration and simulation capabilities, providing an integrated information platform that facilitates effective communication and collaboration among project participants.
