Reference Measurement of Roundwood by Fringe Projection [PDF]
Forest Products Journal, 2021 Abstract The metrological verification of log scanners requires logs with accurately known dimensions as test objects. The measurement of the lengths and diameters must be traceable back to the SI (International System of Units) unit of length. The results have to be reported with the corresponding measurement uncertainties.

LiDAR as a Tool for Assessing Timber Assortments: A Systematic Literature Review
Remote Sensing, 2022 Forest ecosystems strongly contribute to the mitigation of climate change impacts through the carbon stored in forests and through harvested wood products, such as sawed wood and furniture, which are obtained from many types of timber assortments. Timber

The economic potential of semi-automated tele-extraction of roundwood in Sweden
International Journal of Forest Engineering, 2022 The mechanization of roundwood harvesting in Sweden has historically cut costs rapidly. However, machinery and work methods have conceptually stayed the same since the introduction of the single-grip harvester. Current trends indicate that the next major

Comparison of alternative roundwood pricing systems – a simulation approach
Silva Fennica, 2015 In a closed market, roundwood buyers pricing system affect the roundwood flow from the stands to different roundwood users. If a buyer is capable to discriminate higher value stands from low quality stands better than its competitors, the buyer should be
