Traditional methods for collecting and processing bridge alignment data are inefficient. This paper proposes the use of three-dimensional laser scanning technology to acquire point cloud steel–concrete composite beam bridges, establish models extract using techniques. The study focuses on specific operational acquisition, techniques analysis results. feasibility effectiveness method verified through a case He Ying Bridge Chuzhou–Tianchang Expressway in Anhui, China. proposed improves efficiency by 75% compared traditional total station measurement.
