Research on Tree Pith Location in Radial Direction Based on Terrestrial Laser Scanning

Research on Tree Pith Location in Radial Direction Based on Terrestrial Laser Scanning

Obtaining the direction of a diameter line through the tree pith is the basis of effective sampling by a micro-drill resistance instrument. In order to implement non-destructive tree pith location in the radial direction, the geometric property of tree pith, the longest chord through the tree pith o...
