[0002] With the development of the economy and the improvement of people's living standards, my country's textile industry has developed rapidly. We use a lot of grey cloth in our lives. Grey cloth refers to natural cotton cloth that has not been printed and dyed. Grey cloth will have defects in the production process. If the defects are not discovered, it will affect the beauty of the cloth. It is necessary to use a defect scanner to detect defects on the surface of the grey cloth.
