实景三维模型的更新策略OA
Updating strategy of 3D real scene model
大规模、快速、精准三维模型的构建技术较为成熟,但后续的维护更新依然耗时且费用昂贵.本文提出一种模型局部更新方法,以湛江市坡头区高山峒村为例,基于单镜头多视角倾斜摄影采集构建更新区域三维模型,对新旧模型通过边界处理、色彩调整、模型融合构建一体化三维模型,以期为后续实景三维模型更新提供应用借鉴.
The technology for large-scale,rapid,and accurate three-dimensional(3D)model construction is relatively mature,but subsequent maintenance and updates remain time-consuming and expensive.This paper proposes a method for local model updates.Taking Gaoshandong Village in Potou District,Zhanjiang City as an example,a 3D model of the update area was constructed based on single-lens,multi-view oblique photography.The new and old models were integrated into a unified 3D model through boundary processing,color adjustment,and model fusion,aiming to provide a reference for future real-scene 3D model updates.
