Abstract: At present, corrugated cardboard have been widely used in production packing, but it is difficult that corrugated cardboard number is measured on production site to enterprises. Hence, a corrugated automatic counting system based on machine vision technology is proposed. Through a detailed analysis of correlation wavelet transform and visual information of corrugated side texture features characteristics, wavelet transform and morphological algorithm is fused to process corrugated cardboard visual information. A wavelet transform is performed on the corrugated cardboard image to using Discrete Meyer wavelet. Corrugated paper number is gotten by acquiring the number of connected domain in visual information of corrugated cardboard. A large number of experiments show that the counting algorithm can obtain the number of corrugated cardboard accurately and stably compared with other algorithm. And then the automatic counting system can meet the need of corrugated cardboard counting in engineering by engineering practical application.
