为实现二维与三维数据的标准化采集与可视化展示,满足集成管理需求,本文基于无人机倾斜摄影测量技术,构建了一套涵盖外业数据采集、内业数据处理及成果展示的全流程解决方案。通过飞前检查、像控点布设及航线规划,确保影像数据的质量。设计数据处理流程,采用专业图像处理软件生成高精度二维正射影像与三维实景模型。依托Cesium开源框架,设计并实现了一种高度交互式的二三维一体化展示系统。经验证,所生成的影像与模型精度达厘米级,符合我国1∶500比例尺标准,为工程测量与地震监测应急等任务提供了有效的数据支持。

In order to achieve standardized collection and visualization display of two-dimensional and three-dimensional data,and meet the requirements of integrated management,this paper constructs a full process solution covering field data collection,office data processing,and result display based on unmanned aerial vehicle oblique photogrammetry technology.The quality of image data is ensured through pre flight inspection,deployment of image control points,and route planning.A data processing workflow is designed and a professional image processing software is used to generate high-precision 2D orthorectified images and 3D real-world models.Based on the Cesium open-source framework,a highly interactive 2D and 3D integrated display system has been designed and implemented.After verification,the generated images and models have an accuracy of centimeter level,which meets the 1:500 scale standard in China and provides effective data support for engineering surveying and earthquake monitoring emergency tasks.
