Abstract

The invention discloses a pine wood texture detection method. According to the invention, a stress wave is used to detect whether a hole is in pine wood; if the hole is in the pine wood, an acoustic surface wave is used to further detect the position of the hole; computer software is used to establish a three dimensional model for the pine wood and the hole; and the hole in the pine wood is accurately showed. The pine wood texture detection method provided by the invention has the advantages that the size of the hole in the pine wood can be accurately detected; the position of the hole in the pine wood can be determined; the three dimensional models of the pine wood and the hole in the pine wood can be acquired; and the pine wood texture detection method has the characteristics of fast detection and good economy.

Description

technical field [0001] The invention relates to a wood quality detection method, in particular to a pine wood texture detection method capable of accurately detecting the positions and sizes of holes in pine wood. Background technique [0002] Non-destructive testing technology is a wood texture testing method that has developed rapidly in recent years. It can quickly measure the physical and mechanical properties of wood without destroying the shape, structure and position of the wood itself. Stress wave nondestructive testing technology for wood can quickly detect the size, specification and basic physical properties of wood without destroying the performance of wood. Based on this advantage, stress wave nondestructive testing technology has attracted more and more attention in recent years. [0003] Stress waves can be used to detect the texture of thick-diameter wood or large trees. However, stress waves have some disadvantages. For example, this method cannot accurately...
