3D laser scanning applied in conjunction with BIM: A fast and automated approach to inverse modeling

Abstract

Nowadays, 3D laser scanning technology is increasingly applied to the construction industry as a means of collecting real-life building information, which is highly accurate, fast, and visualized, and can improve the efficiency and quality of construction projects, saving time and cost. The integration of 3D laser scanning and BIM technology generally requires reverse modeling of the point cloud. There are many ways to reverse model a 3D model from a point cloud model, but how to reverse model more efficiently is still the current research direction. In this paper, we propose a method for reverse modeling of point cloud by combining 3D laser scanning technology and Dynamo visual programming platform, which can perform rapid and automatic reverse modeling of shaped components and add family libraries, which can be retrieved at any time in the subsequent projects and make secondary edits to the constructed model.
