2018年浙江省局部区域倾斜摄影三维模型数据

数据包含1.5平方公里浙江局部区域（城区）无人机倾斜摄影三维模型数据和0.5平方公里浙江局部区域（山区）无人机三维场景数据，产品生成时间为2018年。城区模型采用固定无人机搭配sony可见光传感器采集倾斜角度45°影像数据，然后结合飞行姿态数据进行三维建模；山区模型采用在无人机搭配sony可见光传感器采集倾斜角度45°影像数据的基础上，进一步应用大疆精灵多旋翼无人机多高度多角度采集部分目标图像数据，然后综合所有影像结合飞行姿态数据进行三维建模。可用于城市建筑物（群）目标识别、三维精细场景建模以及三维场景分析等相关算法研究和验证。

This dataset contains 1.5 square kilometers of oblique photogrammetric 3D model data of a partial urban area in Zhejiang Province, and 0.5 square kilometers of UAV-based 3D scene data of a partial mountainous area in Zhejiang Province. The product was generated in 2018.
For the urban 3D model, a UAV flying along a fixed flight route and equipped with a Sony visible light sensor was used to collect oblique images at a 45° inclination angle, followed by 3D modeling combined with flight attitude data.
For the mountainous 3D scene data, on the basis of collecting 45° oblique images using a UAV equipped with a Sony visible light sensor, additional target image data were collected at multiple altitudes and angles using a DJI Phantom multirotor UAV. Comprehensive 3D modeling was then performed by integrating all collected images and flight attitude data.
This dataset can be applied to the research and validation of relevant algorithms including urban building (cluster) target recognition, fine-grained 3D scene modeling, and 3D scene analysis.
