Title:
METHOD FOR PAIRING WOOD OF LOG STACK
Document Type and Number:
WIPO Patent Application WO/2023/045319
Kind Code:
A1
Abstract:
Disclosed in a technical solution of the present invention is a method for pairing wood of a log stack. The pairing method is as follows: step 1: stacking logs in place; step 2: photographing cross section images of a front side and a rear side of the log stack; step 3: selecting a cross section of any one piece of wood provided with a two dimensional code from the front side cross section image, and searching from the rear side for a cross section of the same piece of wood as the wood of the front side by means of a loss feature algorithm, and successfully pairing; and step 4: calculating wood dimension data of each successfully paired piece of wood. The present invention is suitable for evaluation of logs in a disordered stack, pairing, analysis, and evaluation of log wood can be more efficiently and rapidly performed, 3D scanning is directly performed and the volume of the wood is obtained, there is low error and a high pairing success rate, labor costs are greatly decreased, and the present invention is more accurate and evaluation speed is quicker relative to current visual evaluation technology.
