针对进口旧机电产品依靠人工外观检验效率较低、失误率大等问题，提出一种基于图像特征分类统计与权重系数（IFCS-WC）的旧机电产品电路板新旧程度判定方法。该方法首先提取图像特征，并将该特征分类；其次，将特征量与预先建立的统计特征数据库的标准特征进行对比，确定其新旧系数；再次，利用特征的新旧系数和权重系数，得出新旧判定系数；最后，将该新旧判定系数与预设值进行比较，得出新旧程度判定结果。该判定方法通过图像特征量的分类统计，快速建立电路板器件的新旧综合判定模型，能够实现电路板新旧程度的自动、便捷、快速、准确检验，可应用于进口旧机电电路板器件的检测。
針對進口舊機電產品依靠人工外觀檢驗效率較低、失誤率大等問題，提齣一種基于圖像特徵分類統計與權重繫數（IFCS-WC）的舊機電產品電路闆新舊程度判定方法。該方法首先提取圖像特徵，併將該特徵分類；其次，將特徵量與預先建立的統計特徵數據庫的標準特徵進行對比，確定其新舊繫數；再次，利用特徵的新舊繫數和權重繫數，得齣新舊判定繫數；最後，將該新舊判定繫數與預設值進行比較，得齣新舊程度判定結果。該判定方法通過圖像特徵量的分類統計，快速建立電路闆器件的新舊綜閤判定模型，能夠實現電路闆新舊程度的自動、便捷、快速、準確檢驗，可應用于進口舊機電電路闆器件的檢測。

The used electromechanical products are usually inspected by artificial vision, which has low efficiency and large errors. This paper presents a circuit board condition judgment method for import of used electromechanical products based on image feature classification statistics and weight coefficient (IFCS-WC). Firstly, the image features is extracted and classified. Secondly, the features are compared with the statistical characteristic database established beforehand to determine the old and new coefficient. The weight coefficient is used to conclude judgment coefficient. Finally, a judgment determination is made by the judgment coefficient compared with preset value. The method can realize circuit board condition automatic, convenient, rapid and accurate detection.
