目标：检测工具器件圆圈处是否缺失，False:NG, TRUE:PASS
运用工具：1.CogPMAlignTool目标定位，2.CogFixtureTool中心点坐标，3.CogBlobTool斑点工具，4.CogResultAnalysisTool运算函数 5.文字显示/高级脚本编辑
1.CogPMAlignTool目标定位
抓取图像，训练角度调整可允许随意反转360度，训练
2.CogFixtureTool中心点坐标
获取坐标位置与GetPose进行对接，获取输入图像
3.CogBlobTool斑点工具
区域选择方形区域
运行查看结果显示（小孔测量）
其中ID2的面积不是我们所需要的地方所以需要进行过滤操作
下一步复制操作 （大孔操作）
极性为白底黑点，也可以理解为亮底黑面，运行查看结果
过滤掉没用的信息，ID2,4,3可以看到是没用的信息
根据性能比填充最小面积为200像素时最优，这里的小孔填充和大孔填充与Opencv很像，小孔填充是利用面积筛选的方式留下需要的信息，大孔填充则是利用类似泛洪填充，或者是闭运算（先膨胀后腐蚀）。
可以看到四个空位已经找到
接下来进行个数计算
4.CogResultAnalysisTool
紧接着需要添加终端，找到可以传输的double类型的数值，具体实现参考上一个VisionPro博客
接着是显示文字，因为需要判断，所以选择高级脚本编写
5.高级脚本判断

代码中有一处判断：
if(c.Result.EvaluatedExpressions["Sum"].Value.ToString() == 4.ToString())
这里进行了强转，string类型是不可以与int类型进行赋值比较
6.VS进行C#的界面要求展示
点击VisionPro Application模块
文件中添加刚刚保存好的 程序
一路next
在界面中添加输入字段
路径为Tools下CogToolBlock中output输出的内容的value值
选用VS执行C#
点击持续运行，qt界面中显示的胃实际检测孔洞数量
