VisionPro_T恤缺陷检测_机器视觉案例

找到T恤缺陷并标记:效果

1.添加T恤图片

2.添加CogToolBlock,方便后续添加代码

3.进入CogToolBlock,先使用CogImageConvertTool将图片转为灰度图在进行后续操作

4.对T恤logo进行模板匹配和定位

附加连线图

将logo框选

定位按照下图链接并运行

5.使用CogPatInspectTool进行图像训练和比较

******找到logo好的图片进行训练(重要)

6.添加CogBlobTool工具找到缺陷的地方

所有线链接好

打开CogBlobTool

7.工具使用完成,以下为代码部分:(图片红框部分为添加的代码)下面有完整代码
