| Abstract: | In this paper, a computer_aided inspection and analysis system is developed to identify any inner defect in casting products. The inspection provides important clues for feedback control of casting production. Seven casting defect types and a total of 56 standard casting defect images corresponding to 8 grades of each type are analyzed. The proposed automatic inspection system based on image sequences incorporates the following new developments: (1) fast image preprocessing algorithms are developed to meet the real_time requirement of on_line inspection; (2) a heuristic method is proposed for the classification and recognition of different types of casting defects; (3) key defect type classifying approaches are presented. |
