Veneer sorting control device, veneer sorting control method, and program for veneer sorting control

A veneer sorting control method comprising:

• a step of setting sorting conditions in sorting of a veneer into a plurality of quality ranks for each of a plurality of kinds of defects in correspondence with a detection state of the defects by a sorting condition setting unit of a computer;
• a step of acquiring a plurality of pieces of veneer image data from an image storage unit that stores the plurality of pieces of veneer image data obtained by imaging a surface in which a defect exists with respect a plurality of the veneers by a veneer image acquisition unit of the computer;
• a step of detecting the plurality of kinds of defects by performing image analysis on the plurality of pieces of veneer image data obtained by the veneer image acquisition unit by a defect detection unit of the computer;
• a step of determining a defect-based quality rank for each of the plurality of kinds of defects with respect to the plurality of pieces of veneer image data acquired by the veneer image acquisition unit in accordance with the sorting conditions set by the sorting condition setting unit on the basis of detections states of the plurality of kinds of defects detected by the defect detection unit, determining the defect-based quality rank overall, and sorting veneers corresponding to the plurality of pieces of veneer image data into the plurality of quality ranks by a quality rank sorting unit of the computer;
• a step of totalizing the number or a number ratio of veneers corresponding to the plurality of quality ranks sorted by the quality rank sorting unit with respect to the plurality of pieces of veneer image data acquired by the veneer image acquisition unit by a totalization unit of the computer;
• and
• a step of displaying a result totalized by the totalization unit on a screen by a display control unit of the computer.

A veneer sorting control program causing a computer to function as:

• a sorting condition setting means that sets sorting conditions in sorting of a veneer into a plurality of quality ranks for each of a plurality of kinds of defects in correspondence with a detection state of the defects;
• a veneer image acquisition means that acquires a plurality of pieces of veneer image data from an image storage unit that stores the plurality of pieces of veneer image data obtained by imaging a surface in which a defect exists with respect a plurality of the veneers;
• a defect detection means that detects the plurality of kinds of defects by performing image analysis on the plurality of pieces of veneer image data obtained by the veneer image acquisition means;
• a quality rank sorting means that determines a defect-based quality rank for each of the plurality of kinds of defects with respect to the plurality of pieces of veneer image data acquired by the veneer image acquisition means in accordance with the sorting conditions set by the sorting condition setting means on the basis of detections states of the plurality of kinds of defects detected by the defect detection means, determines the defect-based quality rank overall, and sorts veneers corresponding to the plurality of pieces of veneer image data into the plurality of quality ranks;
• a totalization means that totalizes the number or a number ratio of veneers corresponding to the plurality of quality ranks sorted by the quality rank sorting means with respect to the plurality of pieces of veneer image data acquired by the veneer image acquisition means;
• and
• a display control means that displays a result totalized by the totalization means on a screen.
