Application of Gray Projection Algorithm to the Quantization of Width between Textures of Instrument

This article describes how in the production process of musical instruments, the width between textures in the panel determine their quality directly. In traditional production process, people observe the texture by eyes to determine whether the panel qualified. This method is inefficient and has a large error, which restricts the industrial production of musical instruments. This article proposes a method of quantitative analysis of panel's texture by using digital image processing technology and gray projection algorithm. Since the method is a non-contact one and the key parameters of the panel texture will be acquired, then the selector can determine the suitable panel. Thus, damage to a panel caused by the contact type when manually selected can be avoided. Experiments show that the method has better accuracy which avoids the errors caused by manual measurement and greatly improves the efficiency of panel selection. Therefore, it is of great significance for industrial production of traditional instruments.
