Reliability of photo-optical measurements of log stack gross volume

In terms of assessing economic impact, one the most important elements in wood supply chain is measurement round wood. Besides one-by-one logs, logs are often measured when stacked at forest road. The gross volume includes wood, bark and airspace widely used for industrial assortments. increasing international attention given to photo-optical systems portable devices due their simplicity use efficiency. aim this study was compare volumes hardwood log stacks using widespread app with two manual section-wise estimations based on German framework agreement timber trade (RVR). were done starting from left (RVR) right sides stacks. results showed an average deviation estimation comparison –2.09% –3.66% while between RVR +2.54%. However, stack had a highly significant effect better accuracy smaller reached larger Moreover, indicated that higher quality closer three analyzed methods compared poor-quality stacks.leftrightleftrightleftright
