| 摘 要： | 利用三维激光扫描系统，获得伐倒木的整体点云数据，利用点云应用微积填充的方式计算出伐倒木的材积，将计算结果与根据伐倒木求积式计算出的材积结果进行比较。结果表明，激光扫描仪测得的伐倒木材积数据精度、测量效率均比较高，可以满足林业调查精度的要求，为快速、高效地测定涉案伐倒木材积提供了技术支持。

| Abstract: | Using the 3D laser scanning system to obtain the overall point cloud data of felled trees. Using the application of point cloud micro-product filling to calculate the volume of felled trees and comparing the results with the volumes that are calculated according to the felled treesquadrature formula. The result shows that the data precision and measure efficiency are both higher using the laser scanner, which can meet the requirements of forestry survey accuracy, and provide technical support for the rapid and efficient measure of the cased involved felled trees. |
