Administration method of lumber

Abstract

In an administration method of a lumber, an outer appearance of a lumber is photographed to obtain an image data, and a three-dimensional coordinate model of the lumber is created from the image data. Then, a minimum diameter and a length of the lumber are obtained from the three-dimensional coordinate model to calculate a mass volume of the lumber. Further, an edge surface pattern appearing on an edge surface of the lumber is extracted from the image data. After various processes are applied to the lumber, an edge surface pattern is recorded to create an edge surface pattern data. A history data, in which histories of the various processes are accumulated, and the edge surface pattern data are correlated and recorded, is constructed. Accordingly, when the edge surface pattern is compared with the edge surface pattern data, it is possible to trace the histories of the various processes.
