Abstract

According to the technical scheme, the invention discloses a pairing method for log piles. The pairing method comprises the following steps that 1, logs are stacked in situ; step 2, shooting section pictures of the front and back surfaces of the log pile; 3, selecting any wood section provided with a two-dimensional code from the section picture on the front side, searching the wood section which is the same as the wood on the front side from the back side through a Loss feature algorithm, and successfully pairing; and step 4, calculating wood size data of each successfully paired wood. The method is suitable for detection of disorderly stacked logs, pairing analysis detection can be more efficiently and rapidly performed on logs and wood, 3D scanning is directly performed to obtain the wood volume, the error precision is small, the pairing success rate is high, the labor cost is greatly saved, and compared with an existing visual detection technology, the method is more accurate and the detection speed is higher.

Description

technical field [0001] The invention relates to the technical field of log size calculation, in particular to a log pairing method. Background technique [0002] As a bulk resource commodity, raw wood is one of the most important links in wood inspection. The wood volume is obtained by measuring the size of the wood. At present, the industry mostly uses manual inspection. [0003] The existing wood automatic ruler detection methods are as follows: [0004] 1. The artificial log scanning system mainly measures the longest diameter and shortest diameter of a single log through a manual handheld scanning device, which is used to reduce the error caused by manual visual inspection of the log diameter. [0005] Although manual inspection can reduce the error caused by visual inspection, it cannot match the two ends of the wood, cannot reduce the labor cost required, and still has potential safety hazards. Multiple pieces of wood cannot be detected at the same time, and the effi...
