摘　　要：针对当前单一数据源不能充分满足城市三维模型(LOD1.3级)快速构建这一现状,梳理分析城市三维模型快速构建任务的特点和现有不同技术方法的效率、自动化程度和准确度,提出基于多源数据的快速构建技术路线。方法按生产工序对技术路线进行了划分,并为建筑物的轮廓采集、高程与高度采集、纹理挂接等主要工序分别提供了多种基于不同数据源的技术方法。生产实践表明:本文技术路线能充分满足快速构建任务对生产效率和成果质量的要求。Aiming at the current situation in which a single data source cannot fully meet the rapid construction of three dimensional city model(LOD 1.3 level),the characteristics of rapid construction tasks of three dimensional city model and the efficiency,automation level,and accuracy existed in different technical methods are sorted out and analyzed.A rapid construction technology route based on multiple data sources is proposed.The technical route has been divided according to production processes,and various technical methods based on different data sources have been provided for the main processes such as building contour collection,elevation and height collection,texture hanging,etc.The production practice has shown that the technical route proposed here can fully meet the requirements of rapid construction tasks for production efficiency and result quality.
