A wood knot and a dead knot with bark can be infallibly detected. A piece of wood is imaged by imaging means (8). Image processing means (1) calculates the circularity of a portion of the captured image and judges the portion having a high calculated circularity as a knot. The knot portion is cut off from the wood image captured by the image processing means (1), parts cut off from the color space of the pixels of the knot portion with a predetermined threshold are judged as blackened parts, and the knot portion having a high ratio of the number of pixels of the blackened parts to the number of pixels of the knot portion is judged as a dead knot.
La présente invention permet de détecter de manière infaillible les nAEuds du bois et les nAEuds morts avec écorces. Le système d~imagerie (8) crée une image du morceau de bois. Le système de traitement de l~image (1) évalue la circularité d~une partie de l~image capturée et considère les parties ayant une circularité élevée comme des nAEuds. Les nAEuds sont supprimés de l~image du bois capturée par le système de traitement de l~image (1). Au-delà d~un seuil prédéfini, les parties retirées de l~espace coloré des pixels des nAEuds sont considérées comme des parties sombres ; les nAEuds comportant une proportion élevée de pixels sombres sont considérés comme des nAEuds morts.
