本研究无人机搭载的相机仅能够采集垂直方向的研究区影像，若采用五镜头、多

This UAV mounted camera can only capture images in the vertical direction in the study area, if a five-camera, multi-angle camera collecting data to generate the point cloud image UAV only to better reflect the individual tree and stand structure feature, but also a larger area of ​​the data collected, data collection more efficient

The camera mounted by the uavor in this study can only capture images of the research area in the vertical direction, if the data is collected with a five-lens, multi-angle camera, the resulting drone image point cloud can not only better reflect the structural characteristics of the single wood and forest, but also can collect the data of the larger area, the data collection efficiency is higher.

The camera carried by the UAV in this study can only collect the image of the study area in the vertical direction. If five lens and multi angle cameras are used to collect data, the generated UAV image point cloud can not only better reflect the structural characteristics of single wood and forest, but also can collect the data of a larger area, with higher data collection efficiency<br>
