Abstract: In order to get the high-quality sound, it is necessary to analyze the texture of the panels when selecting materials for the musical instruments. Usually, the choice of panels is measured manually which greatly reduces the production efficiency of musical instruments. It lacks the scientific theory basis in evaluating the panel quality. Computer image processing method can be used to automatically judge the panel specification. By analyzing the texture of the panel, and combining gray projection algorithm with the mean value, an automatic calculation method for measuring the width between textures of a panel is proposed. Experiments show that the method can reduce the error of manual measurement and speed up the selection of better panels, and it performs well in accuracy and robustness.
