A model for roundwood of planted forests

Abstract

Forest harvesting is quantified in stereo volume. Therefore, there is no information on the types and quantities of products that can be extracted from trees. Information on timber products, as well as their evaluation, can assist forestry producers in trading. Another purpose is to provide support information for companies that purchase forests, such as the amount of most sold pieces and the amount of wood residue. In this work, a model to segment trees into roundwood pieces in the dimensions provided by the user was developed and validated. The required data are the diameter at breast height (DBH), total height of the trees, taper data, and the diameter and length dimensions of the roundwood pieces selected by the user. The validation was performed on the harvest of 8-year-old eucalyptus clone I224 and VM1, in an ILPF system and monoculture. The number of errors greater than 20% for the dimensions of pieces selected and calculated by the algorithm did not exceed 8% of the frequency distribution.
