Abstract

The invention discloses a wood material defect detection apparatus and a method thereof. The apparatus comprises a detection tank body, a conveyor belt, a lamp source, a camera, and a controller; theconveyor belt, the lamp source and the camera are placed in the detection tank body, the lamp source and the camera are fixed over the conveyor belt, a detection area is indicated at the conveyor belt, the detection area are also indicated at an end surface of the detection tank body, the lamp source is fixed in the detection area of the detection tank body, the lamp source number is multiple, andthe lamp sources are uniformly distributed in the detection area, and the lamp sources are used for providing light with equal brightness for the detection area of the conveyor belt while detecting;the camera is fixed in the detection area at the end surface of the detection tank body, an output terminal of the camera is connected with the input terminal of a controller, the camera is used for taking pictures of a to-be-detected wood material, and transmitting the pictures to the controller for processing; and the controller is used for obtaining a defect parameter of the to-be-detected woodmaterial according to the pictures transmitted by the camera. The apparatus and the method can increase the detection precision and efficiency.

Description

technical field [0001] The invention relates to the field of wood material detection, in particular to a device and method for wood material defect detection. Background technique [0002] The application fields of wood materials are very wide. Usually, before use, it is necessary to detect the surface defects of the wood itself, or after processing, that is, the artificial boards need to detect the defects of the finished product. Different application fields have different qualification standards for wood materials. Therefore, For different application fields, it is necessary to detect the specific parameters of the defect and determine whether it meets the standards used. [0003] Existing detection of defects in wood materials is usually done manually one by one, the detection efficiency is low, and it is not suitable for mass processing. There are also inspection machines specially designed for defects in wood materials, but the inspection machines are expensive and co...
