摘　　要：如何快速有效地获取高精度、高分辨率的地理空间信息数据已经成为城市智慧化发展的重要问题,本文分析了三维街景地图的发展现状与目前多数街景数据采集手段存在的问题,介绍了利用中海达一体化移动三维激光测量系统采集点云数据的过程,以及结合徕卡CYCLONE软件进行建模的方法,对原始测量的点云数据进行去噪、平滑、拼接配准等处理后得到目标建筑物精准的表面信息,进而构建三维表面模型,将校正过的照片进行纹理映射得到真实的三维模型。实验证明:此方法可快速地获取较为精准的点云数据并且实现对建筑物的快速建模。With the advent of the era of big data, how to quickly and efficiently access high-precision, high-resolution geospatial data has become an important issue of urban intellectual development. This paper analyzes the cunrent situation of the development of three-dimensional street map and current problems of most street view data collection means, and introduced the use of three-dimensional movement of the Haida integration of point cloud data collection process and describes a method of combining laser measurement system Leica CYCLONE modeling software. To get the raw point cloud data to be denoised, smoothed, spliced and other process, target building accurate surface information is achieved, and then the three-dimensional surface model is built, The real 3D models are achieved through texture mapping of the corrected photo. Experiments show that, this method can quickly obtain more accurate point cloud data and can achieve rapid modeling of the building.
