摘要
文章以宁波市老旧街道更新改造项目为例,对三维激光扫描技术在老旧街道更新中的应用进行了研究。首先利用三维激光扫描仪采集街道点云数据,然后对点云进行拼接、去噪等处理,并导入计算机辅助设计(CAD)绘制建筑立面线划图,再结合3ds Max和Unity3D软件构建街道三维数字模型。实践表明,利用三维激光扫描技术可快速、准确地进行建筑物立面的三维重建,精度符合相关规范要求,能够满足老旧街道更新改造的应用需要。
This paper takes the renewal and reconstruction project of old streets in Ningbo City as an example to study the application of 3D laser scanning technology in the renewal of old streets.Firstly,the 3D laser scanner is used to collect the street point cloud data,and then the point cloud is processed through splicing,denoising,and the Computer-Aided Design(CAD)is introduced to draw the building facade line graphics,and then the 3D digital model of the street is constructed by combining 3ds Max and Unity3D software.The practice shows that the 3D laser scanning technology can quickly and accurately reconstruct building facades,and the accuracy meets the requirements of relevant specifications,which can meet the application needs of the renewal and reconstruction of old streets.
