基于Smart3D的双镜头无人机倾斜摄影大面积实景三维建模研究

Research on Real 3D Modeling of Large Area with Two Cameras UAV Oblique Photography Based on Smart3D

基于提高无人机的续航能力和其对大面积实景三维建模的需要,减轻无人机载重,利用双镜头无人机进行大面积原始影像的获取,通过Smart3D进行三维模型的建模实验。实验验证了双镜头无人机倾斜摄影测量平台能有效提高无人机的续航能力,满足大面积实景三维建模的需要,由于无人机航摄姿态的不稳定性,在三维建模中,需要加入相应的控制点完善三维模型的构建,且三维模型表现出丰富的地面纹理信息。

Based on improving the endurance of UAV and meeting the need for large-area real-world 3D modeling,reducing the load of UAV,using dual-lens UAV to acquire large-area original images,and performing 3D model modeling experiments through Smart3D.Experiments have verified that the dual-lens UAV oblique photograph platform can effectively improve the UAV's endurance and meet the needs of large-area real 3D modeling.Due to the instability of the UAV's oblique photography attitude,in the process of 3D modeling,it is necessary to add corresponding control points to complete the construction of the 3D model,and the 3D model exhibits rich ground texture information.
