Abstract

The invention provides a timber recognition device and method, and the device comprises an image collection device and a rotating device, and the image collection device and a cross section of timberare driven by the rotating device to move relatively. The image collection device is used for acquiring a plurality of images of the timber at different angles; the plurality of images can construct athree-dimensional model of the timber section. For the first time, a method for identifying the timber by constructing a three-dimensional model of wood textures and comparing three-dimensional shapes and textures is provided. The method makes full use of the difference of the three-dimensional morphology of the cross section of the timber and is higher in recognition accuracy.

Description

technical field [0001] The invention relates to the technical field of wood shape measurement, in particular to the technical field of wood 3D shape measurement. Background technique [0002] The price of different woods varies greatly, and it is often the case that inferior wood is used as good wood for trading. Especially in collections, the price gap between different woods is huge, and it is difficult for ordinary consumers to distinguish. [0003] At present, there are also some technologies for wood identification, usually by taking many photos as samples, and then training the neural network to obtain a neural network that can identify a certain type of wood. When detection is required, take a photo of the wood to be identified and send it to the neural network for identification. This method takes advantage of big data and the learning function of neural networks, and has certain discriminative properties. However, since counterfeiting technology is also improving...
