实测单木位置所做圆形缓冲区与分割树冠重叠面积占各自或其中一方的50%以

Found positions do individual tree crown segmentation and overlap circular buffer area accounts for 50% or more, each of which one, it is determined that the correct segmentation; dividing the crown of one or more circular buffers Found single timber or individual tree circle appears Found shaped buffer area no more than 50% split crown, it is determined that leakage points; Found plurality of divided individual tree crown occur within a circular buffer, it is determined that an excessive division [39].

The overlapping area of the circular buffer and split crown made at the measured single wood position is determined to be more than 50% of the respective or one side, and the area of more than 50% of the measured single wood circular buffer or the measured single wood circular buffer appears in the split canopy shall be determined to be a leakage point. The measured single wood circular buffer for the occurrence of multiple split crowns, is determined to be excessive segmentation.

If the overlapped area of the circular buffer zone and the segmented tree crown in the measured single wood position accounts for more than 50% of each or one of them, it is determined as correct segmentation; if there is more than one measured single wood circular buffer zone in the segmented tree crown or more than 50% of the measured single wood circular buffer zone in the segmented tree crown, it is determined as missed segmentation; if there are multiple segmented tree crowns in the measured single wood circular buffer zone, it is determined as missed segmentation It is determined as over segmentation [39].<br>
