Method and apparatus for calculating the woodlot frame variables

摘要

The invention concerns a method for measuring trunk quantities in a stand of trees according to which all trees are optically recorded from a selected point within a specified spacing under a 360 degree circle. Recording occurs with accurate distance measurements and measurement of torsion angle so that the tangent is calculated as the difference between measured absolute torsion angle from the discontinuity points detected on both sides of a trunk.
