The extraction of individual tree parameters by terrestrial three-dimensional laser scanner had become a research hotspot in the field of forestry measurement,especially in forestry^data tables.Based on the data of Cypress trees and Masson pine trees collected by three-dimensional laser scanner,two main tree measurement factors,DBH and tree height,were extracted and compared with the actual data.The results showed that the precision of DBH factor extraction by convex hull algorithm was considerably higher and the relative error was 1.18%.The precision of tree height measurement was higher and ...
