Automatic Tree Crown Volume Calculation Method Based on Point Cloud Data
摘要
Abstract
Tree crown volume is an important parameter in the study of biomass and 3D green biomass.In view of the problems such as the complexity of the tree crown topology structure,the poor accuracy and low degree of automation in the existing method,this paper presented an automatic extraction measurement of the tree crown volume method with laser point cloud data.Based on the tree point cloud data,the automatic calculation was achieved by using the sector area approximation and the irregular slice segmentation algorithm.Sample trees in the experimentation area were measured and calculated.The new method achieved the nondestructive automatic calculation of the single tree crown volume.Compared with the traditional method,it not only saved manpower,but also improved the accuracy of the calculation by 6.17％.Also it had a certain practical significance and application value,which could provide reference for the research of crown structure.关键词
