|
摘要
针对小区域构建三维模型,现有的建模方法需要大量的时间和人力物力,难以实现模型数据的快速获取、存储和在线浏览。本文提出了一种基于消费级无人机倾斜摄影技术获取实景三维模型的方法,介绍了通过消费级无人机进行倾斜摄影生产三维模型的流程和修复三维模型的方法,验证了通过消费级无人机进行倾斜摄影测量生成三维模型的几何精度,实现了实景三维模型入库、分析、标注属性、在线浏览和单体化的功能,最终实现了小区域快速生成实景模型和实景模行可视化,对实际生产有一定意义。
To build a three-dimensional model for a small area, the existing modeling methods need a lot of time and manpower and material resources, and it is difficult to achieve rapid acquisition, storage and online browsing of model data. This paper presents a method of obtaining three-dimensional model of real scene based on consumer-level UAV tilt photography technology, introduces the process of production of three-dimensional model based on consumer-level UAV tilt photography, expounds the method of repairing the real scene model, analyses the geometric accuracy of three-dimensional model generated by consumer-level UAV tilt photography, and realizes the storage, analysis and storage of three-dimensional model of real scene. The functions of labeling attributes, online browsing and integration,realizing fast generation of real scene model and visualization of real scene model row, have certain significance for actual production.
