Research on Detection System of Ceramic Tile Based on Image Processing

摘要

In order to realize the automatic detection of exterior wall ceramic tile and the automatic classification of the product quality, the exterior wall ceramic tile automatic detection system based on the image acquisition and processing technology is designed. Aiming at the characteristics of small volume, large quantity and random position distribution of tile, the automatic tile detection system based on image acquisition card, PC and PLC is designed, and image processing algorithm of edge enhancement, dynamic finding threshold value and edge extraction is adopted This paper describes the algorithm of image processing and the method of error calculation, and introduces the mechanical structure and working principle of the system. Practical application shows the high accuracy and efficiency of the detection of ceramic tile of this system, which is applicable to the quality control of production process of ceramic tile.
