摘要
实景数字孪生集实景三维、数字孪生、摄影测量、云计算等新型技术于一体,是一种将真实地物或空间1∶1复刻到虚拟空间、反映其全生命周期过程的数字化技术,针对现有摄影测量技术不能较好的对复杂地貌进行自动化高精度数字孪生建模的问题,提出了一种针对张家界地貌的智能航迹规划方法,并将其成功应用于实景三维张家界项目中,实现在极端复杂环境下的快速高精模型构建。结果表明,该方法在作业安全性、采集效率、成果质量上较传统摄影测量方法提升显著,所构建的三维模型相对精度达到厘米级甚至毫米级,高精度复刻了张家界立体地貌,可为国土空间规划、景区智能化管理、大众出行导航、地质灾害防治、林业普查、生态修复等工作提供更加科学精准的三维数字空间分析基础。
Real-view twin is a new technology integrating 3D real sence,digital twin,photography measurement,cloud computing,etc into one.It is a digital technology that carves real objects or space 1∶1 to virtual space and reflects its entire life cycle process.In order to solve the problem that existing photogrammetry technology cannot perform automated high-precision digital twin modeling of complex landforms,an intelligent track planning method for Zhangjiajie landforms was proposed and successfully applied to the 3D real sence Zhangjiajie project.Achieving fast and high-precision model construction in extremely complex environments.The results show that this method has improved significantly in terms of operational safety,collection efficiency,and quality of results than traditional photography measurement methods.The relative accuracy of the three-dimensional models constructed reaches centimeter or even millimeter.High-precision reproduction of the three-dimensional landforms of Zhangjiajie to provide more scientific and accurate threedimensional digital space analysis foundation in Land and spatial planning,intelligent management of scenic spots,mass travel navigation,geological disaster prevention,forestry census,ecological restoration and other work.
