| 摘 要： | 针对倾斜摄影数据服务共享保密要求高、倾斜摄影数据包SLPK不同精度数据制作复杂的问题，本文基于开源I3S标准规范与解析倾斜摄影在线服务结构特征，研究实现了一种I3S标准的倾斜摄影服务精度动态控制方法。该方法可根据服务需求，通过控制索引树节点级别，基于一套数据实现多种精度的在线服务；作为实景三维建设的重要技术支撑，具有良好的实用价值。

| Abstract: | Aiming at the problem of high confidentiality requirements for the sharing of oblique photography data services and complex production process of different precision oblique photography data packets, based on the open source I3S standard specification, by analyzing the structural characteristics of oblique photography online services, this paper researches and realizes a dynamic control method of oblique photography service accuracy based on I3S standard. By controlling the node level of the index tree, a set of data can be used to realize online services with multiple precisions according to service requirements. As an important technical support for real 3D construction, it has good practical value. |
