基于免像控无人机倾斜摄影测量的实景模型裸眼三维测图研究

Three-dimensional naked-eye mapping of real-world model based on tilt photogrammetry of image-free UAV

为了验证免像控无人机倾斜摄影测量的可行性和精度,以吉林建筑大学北校区为例,采用免像控无人机对其进行倾斜摄影,并利用ContextCapture进行三维实景建模。在三维实景建模上采集信息制作学校校区地形图,采用外业实测检查点的方式对地形图的平面精度及高程精度进行了验证,并对免像控无人机倾斜摄影测量在实景模型裸眼三维测图中的可行性、精度和工作效率进行了客观评价。

In order to verify the feasibility and accuracy of image-free UAV tilt photogrammetry,this paper takes the North Campus of Jilin University of Architecture as an example,uses image-free UAV for tilt photography,and uses ContextCapture for three-dimensional scene modeling.On the basis of three-dimensional scene modeling,the topographic map of school campus is made by collecting information,and the plane accuracy and elevation accuracy of the topographic map are verified by the way of field survey checkpoints.Finally,the feasibility,accuracy and efficiency of image-free tilt Photogrammetry for UAV in naked-eye three-dimensional mapping of scene model are evaluated objectively.
