从实景三维建模到数字孪生建模
从实景三维建模到数字孪生建模是国家数字经济和智慧社会建设与发展的基本需求。本文探讨了实景三维建模和数字孪生建模的关键技术内涵，介绍了数字乡村、未来社区和智能铁路等典型应用场景。广域范围实景三维建模在低成本高效数据采集和智能化自动化三维精细建模与动态更新方面面临挑战，城市级或重大工程级的数字孪生建模在全要素整体性的表征数据与机理模型集成表达方面还存在关键技术瓶颈。测绘技术亟须多学科交叉融合创新，突破天空地有机协同实时动态获取多细节层级实景三维数据、智能化处理多专业多尺度多模态时空数据、不完备数据条件下复杂场景的三维实体化精细建模、表征数据与机理模型结合的全生命周期数字孪生模型动态构建等核心关键技...
