Pine Logs Sorting as a Function of Bark Thickness

The process of sorting softwood raw materials is aimed at full automation. Techniques such as laser and optical scanning, used in measuring wood material with the layer bark, are based on an analysis external shape log. consequence this use constant ranges bark deductions, which often affected by errors resulting from averaging values. thickness influenced many factors, tree species quality habitat trees have grown. In case pine wood, range adopted diametral intervals for processed plays a significant role. automatic results showed numerous cases log-size mismatch. methods that assume measurement deductions should be made experiments take into account resources base. Despite high correlation between size deduction average (r = 0.85), mean value error adjustment to maximum was 45%. analyzed correlated. level coefficient r 0.72. order increase accuracy process, adjusted values each group.
