VisionPro[CogBlobTool]斑点工具,圆形标注(C#脚本)

标签：VisionPro tool 斑点 C# using circle Cognex CogBlobTool

圆形标注

标注图样板

添加CogToolBlock工具 图像源拖入CogToolBlock

在CogToolBlock中添加斑点工具拖入图像源

因为图像比较对比清晰,模式选用硬阈值(动态)

可以清晰的识别出斑点

创建C#脚本

​ 选用C#Advabced Scrip高级脚本

CogGraphicCollection

 //CogGraphicCollection是一个所有图像存储和管理图形对象 集合的元素为 ICogGraphic类型
  //我们用于存储圆形 CogCircle
  CogGraphicCollection graphs = new CogGraphicCollection();

斑点工具GetBlobs方法 , 斑点工具对象名.Results.GetBlobs()

该方法得到的是一组斑点信息,每个斑点信息都是CogBlobResult类型
