摘要
旨在探索基于机载激光雷达的城市三维建模技术设计与应用效果。以江西省某生态修复区三维建模工程为例,设计并实施了一套以“多模态数据协同采集—智能融合建模—动态迭代更新”为主的技术方案。经工程验证发现,该方案对于复杂地形区域尤其是塌陷区、裸岩区等具备明显的数据获取精度提升效果,模型空间误差控制在±3 cm以内,可达到对生态修复区域地貌、水文、地质综合信息高保真表达的目标。因此,对于城市生态修复区数字建模与动态监测的研究,可以有效解决传统建模中数据精度低、多源融合难、更新滞后的问题。
This study aims to explore the design and application effectiveness of urban 3D modeling technology based on airborne LiDAR.Taking a 3D modeling project in an ecological restoration area of Jiangxi Province as an example,a technical scheme centered on"multi-modal data collaborative acquisition—intelligent fusion modeling—dynamic iterative updating"is designed and implemented.Through engineering validation,it is found that this scheme significantly enhances data acquisition accuracy in complex terrain regions,particularly in subsidence areas and bare rock zones,with model spatial errors controlled within±3 cm.This achieves high-fidelity representation of comprehensive information(e.g.,topography,hydrology,and geology)in ecological restoration areas.Consequently,for research on digital modeling and dynamic monitoring of urban ecological restoration zones,the proposed approach effectively addresses issues of low data accuracy,multi-source data fusion difficulties,and outdated updates inherent in traditional modeling methods.
