Ji'nan Survey Bureau，Yellow River Conservancy Commission，Jinan，handong Province，25ooo China Abstract： Digital twin technology can use3D modeling technology to virtualy project the physical world，and is widelyused in thefieldsof intellgent manufacturing，smart cities，and traffc control.As the comerstone of 3D modeling，the fine splicing methodof point cloud data directlyaffcts the accuracyand practicabilityof the model. Based on this，this paper proposes a 3D modeling point cloud fine splicing method fordigital twin systems.The purpose of this method is to achieve seamlessfusion of point cloud data simultaneously through eficient and accurate algorithms， providing reliable guarantees for subsequent model construction and applications.
