倾斜摄影测量面向城镇实景三维建模及精度分析

Real 3D modeling and accuracy analysis of tilt photography for urban

随着"实景三维中国"建设计划的推进,大规模、大范围、高精细的实景三维生产需求日益增长。本文以河南省鹤壁市淇滨区钜桥镇北郭庄村为试验区,首先通过复合翼无人机搭载RIY-D2M五镜头相机,对该区域进行五角度倾斜摄影拍摄;然后使用ContextCapture Center软件进行实景三维建模;最后通过DP-Modeler软件对模型进行精细化处理。基于像控点坐标的模型进行精度评价,结果符合《三维地理信息模型数据产品规范》Ⅰ级精度,表明该方法可以满足新型测绘下的实景三维建模。

With the advancement of the"Real Scene 3 D China"construction plan,the demand for large-scale,large-scale,high-precision real 3 D production is increasing.This paper takes Beiguozhuang Village,Juqiao Town,Qibin District,Hebi City,Henan Province as the experimental area.First,the compound-wing drone is equipped with a RIY-D2 M five-lens camera,and the tilt photogrammetry technology is used to shoot the area from five angles.Bentley’s ContextCapture Center software produces real-life 3 D models,and again,the models are refined through Wuhan Tianji Airlines’DP-Modeler software.Finally,the accuracy of the model is evaluated through the image control points,and the evaluation results meet the level I accuracy of the"Three-dimensional Geographic Information Model Data Product Specification",indicating that the method meets the real-world three-dimensional modeling under the new surveying and mapping.
