The embodiments of the invention provide a plate defect identification method and device. In one embodiment, the plate defect identification method includes the following steps: acquiring multiple groups of feature images corresponding to multiple features of a plate; extracting features from the feature images; analyzing the features to get specified feature parameter groups; training a set composed of the specified feature parameter groups corresponding to the feature images based on a PSO (Particle Swarm Optimization)-SVM (Support Vector Machine) algorithm to classify the feature images, and determining the defects of the plate according to the classification result. 本发明实施例提供板材缺陷识别方法及装置，在个实施例中，所述板材缺陷识别方法包括：获取板材的多个特征对应的多组特征图像；对多组所述特征图像进行特征提取；对所述特征进行分析以获得指定特征参数组；对所述多组特征图像对应的指定特征参数组形成的集合基于PSO-SVM算法进行训练以对所述多组特征图像进行分类，并根据分类结果确定板材的缺陷。
