摘要
针对长条状不规则建筑物结构复杂、形状不规则及纹理信息丰富等特征所导致的三维建模难度较大,存在模型空洞较大、纹理缺失的问题,研究无人机不同航线对三维建模质量的影响。实验以搭载5镜头倾斜相机的无人机为航拍设备,对长条状建筑物规划"垂直""平行"2种不同航线来采集影像;以航空摄影测量理论为基础构建建筑物实景三维模型。从模型建模完整性及控制点点位精度2个方面对比分析2种不同航线建筑物三维模型的建模质量。实验结果表明,针对平行、长条状分布的建筑物,综合建模完整性及控制点点位精度分析,"平行航线"的三维建模方法优于"垂直航线"的三维建模方法。此分析结论可为城市三维建模时航线规划提供辅助决策。
Aiming at the characteristics of the complex structure,irregular shape,and rich texture information of the long irregular buildings,the three-dimensional modeling(3D)is difficult,as well as the model has large holes and the texture is missing,the quality assessment of 3D modeling based on different UAV route planning is researched in this paper.The UAV equipped with the 5-lens tilt camera as the aerial photography equipment is taken to plan two route for the same building,such as"vertical route"and "parallel route".Two UAV image sets are constructed 3D models of the same building based on aerial photogrammetry theory.The model quality and the control point positional accuracy are reviewed.The experimental results show that comparing the model quality and the control point positional accuracy,the 3D modeling method based on"parallel route"is better than that on the"vertical route".This analysis conclusion can provide auxiliary decision for route planning in urban 3D modeling.
