摘要/Abstract

摘要： 随着智慧城市、实景三维中国等概念的兴起，倾斜摄影测量三维实景建模的规模将越来越大，未来可达到城市级。城市级的实景模型成果可作为基础数据，提供给本城市多个项目使用。在实际应用中，由于模型应用软件承载能力或项目实际需求范围小等原因，需要对实景模型成果按照需求进行精确提取。一般的倾斜摄影三维实景模型提取方法效率低，提取精确度不高。笔者依据倾斜摄影三维模型的数据组织特点，探讨如何利用Arcgis软件建立索引，实现对倾斜摄影三维模型成果的精确提取。

Abstract: With the development of smart city and the reality 3D meshes of China, the scale of 3D reality modeling based on oblique photogrammetry is getting larger and larger. In the future, the city level will be achieved. The city-level reality 3D model can be used as basic data for multiple projects. In practice, due to the limited load capacity of the model application software or the actual scope of the project, accurate extraction of the results from the reality 3D model is needed. The common extraction method is inefficient and the extraction accuracy is not high. Based on the data organization characteristics of the oblique photography 3D model, this paper discusses how to use Arcgis software to establish an index to obtain accurate segmentation of the oblique photography 3D model results.

Key words: oblique photography, index establishment, data extraction, Arcgis
