Abstract
Disclosed is an apparatus and method configured for classifying timber logs in a wood processing chain. The apparatus comprises an image processor. The image processor is configured to receive a first log image of a first end of log and determine a first end pattern. The image processor is configured to receive a second log image of a second end of the same log, wherein the second end is opposite the first end. The image processor is further configured to determine a first pattern in the first end and a second pattern in the second end. Lastly, the image processor is further configured to determine a characteristic of the log based on the first pattern and the second pattern.
Claims19
An apparatus configured for classifying timber logs in a wood processing chain, wherein the apparatus comprises an image processor, wherein the image processor is configured to:
- receive one or more first log image each of a first end of log;
- receive one or more second log image of a corresponding second end of the same logs, wherein the second end is opposite the first end;
- determine a first pattern in each of the first ends;
- determine a second pattern in each of the second ends;
- determine a characteristic for each log based on the corresponding first pattern and the second pattern,
- determine that the corresponding log has been subjected to a growth issue,
- determine that the characteristic indicates a quality factor, and
- determine the quality factor based on the difference, wherein a big difference indicates a low quality.
