Automatic detection system for sandpaper defects based on digital image processing

Sandpaper is an indispensable and important article in industrial production and daily life. However, due to technological reasons, not all sandpaper can meet the standard. At present, in the traditional industrial production, in order to improve the quality of sandpaper, the usual way to identify the problem sandpaper is human eyes. Due to the influence of personnel factors, the accuracy and reliability of this way are low, and the production cost is high, and the efficiency is low. Therefore, we designed an automatic detection system of sandpaper defects based on digital image processing technology, which can effectively improve the recognition rate of defective sandpaper, reduce the production cost and improve the production efficiency.
