Abstract:
(EN) Disclosed are an inclined saw timber defect detection apparatus and method. The apparatus comprises a laser emitter and an industrial area array camera. Light emitted by the laser emitter to a surface of saw timber is reflected and then received by the industrial area array camera. An included angle of 90° is formed between incident laser light and an optical axis of the industrial area array camera, and the incident laser light is inclined. The apparatus and method in the present invention have high measurement precision, are convenient to use, and have advantages of being able to detect multiple points on a cross area simultaneously and perform automatic continuous detection.
(FR) La présente invention concerne un appareil et un procédé de détection de défaut de bois de sciage incliné. L'appareil comprend un émetteur laser et une caméra à matrice de zone industrielle. La lumière émise par l'émetteur laser vers une surface de bois de scie est réfléchie, puis reçue par la caméra à matrice de zone industrielle. Un angle inclus de 90° est formé entre la lumière laser incidente et un axe optique de la caméra à matrice de zone industrielle, et la lumière laser incidente est inclinée. L'appareil et le procédé de la présente invention présentent une précision de mesure élevée, sont pratiques à utiliser, et présentent les avantages de pouvoir détecter des points multiples sur une zone transversale simultanément et effectuer une détection continue automatique.
