本研究借助无人机摄影测量采集的高分辨率影像，应用运动结构重建技术生成研

This study by UAV photogrammetry high resolution image acquisition, image reconstruction point cloud technology generated applying motion study area configuration data, and using the determination of different ages in the study area dividing method of the point cloud from poplar and fir-based comp fed individual tree extract and verify the accuracy;

With the high-resolution image collected by drone photogrammetry, this study uses motion structure reconstruction technology to generate image point cloud data in the study area, and uses the distance-based division method of point cloud to extract and verify the accuracy of different age sequoia and poplar trees in the study area.

In this study, the high-resolution image collected by UAV photogrammetry is used to generate the point cloud data of the image in the study area, and the distance discrimination and segmentation method based on the point cloud is used to extract the single wood of different ages of Metasequoia and poplar samples in the study area and verify the accuracy;<br>
