【摘要】 以西安市高新区父慈村为例,采用天璇Ⅱ号无人机搭载DSC-RX1RM2相机进行数据采集,利用Context Capture软件完成三维重建,并尝试用DP-modeler对三维模型进行精细化处理,得到了较好的模型效果。通过外业实测检查点对模型进行精度分析,其点位中误差为4. 1 cm,表明该方法可以满足实景三维建设的需要,为智慧城市的建设提供了有力的数据支撑。更多还原

【Abstract】 UAV are widely used in the 3D modeling of tilt photography. This paper takes a village of Xi’an High-tech Zone as an example,using the Tianxuan ⅡUAV which equipped with DSC-RX1 RM2 camera for tilt photography data acquisition. Context Capture software was used as a platform of data processing. In order to obtain better model effect,we modified the realistic 3D model through DPmodeler software. Check point is measured to evaluate the accuracy of 3D -model. The mean square error of a point in plane is 4. 1 cm.By analyzed the precision of the results,it is shown that this method can meet the needs of 3D construction of real scene,and provides strong data support for the construction of smart city.更多还原
