摘要
基于倾斜摄影和激光点云技术进行城市实景三维模型构建,以新建南门古建筑为研究对象,通过多源数据的融合重建,旨在保护、传承和展示该建筑的历史文化价值。数据获取阶段使用倾斜摄影测量和激光点云技术获取了倾斜摄影测量点云数据和三维激光点云数据。在多源数据融合重建阶段,通过数据空间配准、坐标系统统一、点云粗配准和ICP配准等步骤,实现了建筑物实景三维模型的构建,精度结果显示该重建方法具有较高的位置精度及完善的几何结构和纹理信息表达能力。
Based on oblique photography and laser point cloud technology,the three-dimensional model of urban reality was constructed.The new Nanmen ancient building was taken as the research object,and the historical and cultural value of the building was protected,inherited and displayed through the fusion and reconstruction of multi-source data.In the data acquisition stage,tilt photogrammetry and laser point cloud technology are used to obtain tilt photogrammetry point cloud data and three-dimensional laser point cloud data.In the stage of multi-source data fusion reconstruction,the 3D model of the real scene of the building is constructed through the steps of data space registration,coordinate system unification,point cloud rough registration and ICP registration.The precision results show that the reconstruction method has high position accuracy and perfect expression ability of geometric structure and texture information.
