 # 印刷电路板（PCB）瑕疵数据集模型
 - 印刷电路板（PCB）瑕疵数据集：[数据下载链接](http://robotics.pkusz.edu.cn/resources/dataset/)，是一个公共的合成PCB数据集，由北京大学发布，其中包含1386张图像以及6种缺陷（缺失孔，鼠标咬伤，开路，短路，杂散，伪铜），用于检测，分类和配准任务。我们选取了其中适用与检测任务的693张图像，随机选择593张图像作为训练集，100张图像作为验证集。AIStudio数据集链接：[印刷电路板（PCB）瑕疵数据集](https://aistudio.baidu.com/aistudio/datasetdetail/52914)
 
-## 已提供的基线模型
-- YOLOv3-Darknet
-- Faster-RCNN-R34
-- FCOS-R50-FPN
-
-## 优化后高mAP模型
-将在9月29日发布,敬请期待。
