Embodiment 1
[0087] According to the overall growth trend of the tree crown, select the sampling points of the tree crown of the target tree in each direction, namely A, B, C, D, E, a total of 5 points, use the non-prism total station to measure the three-dimensional coordinates of the sampling point counterclockwise, and sample The three-dimensional coordinate data of the points are shown in Table 1.
