VisionPro实战之胶囊缺陷识别

目录

1.案例要求

2.思路和操作

1.Block工具，格式转换

2.匹配所有胶囊，不包括空胶囊

3.使用颜色识别工具

4.编写脚本进行遍历

3.最终实现效果

1.案例要求

测量出每一版胶囊是否合格，不合格的话缺陷是什么都标注出来，下面这张图片是合格胶囊的示例。

2.思路和操作

1.Block工具，格式转换

2.匹配所有胶囊，不包括空胶囊

这里适当调整参数以便更好地匹配到非空胶囊

3.使用颜色识别工具

这两种不合格的产品我们可以通过颜色识别跟正常的胶囊区分开

4.编写脚本进行遍历

CogGraphicCollection col = new CogGraphicCollection();//图形工具存放内容
CogGraphicLabel label = new CogGraphicLabel();//输出总的胶囊是否合格
CogGraphicLabel[] labels = new CogGraphicLabel[15];//输出单个胶囊是否合格

col.Clear();//清除内容，防止内容留存输出到别的图片

//加载组件对象

CogPMAlignTool p1 = mToolBlock.Tools["CogPMAlignTool1"] as CogPMAlignTool;
CogColorMatchTool cm = mToolBlock.Tools["CogColorMatchTool1"] as CogColorMatchTool;

int count = p1.Results.Count;//识别出胶囊的数量
int count_ng = 0,count_ok=0;//count_ng表示缺陷数量，count_ok表示合格数量

//遍历每一个保险器件

for(int i = 0;i < count;i++)
{
  CogCircle c1 = new CogCircle();
  c1.CenterX = p1.Results[i].GetPose().TranslationX;
  c1.CenterY = p1.Results[i].GetPose().TranslationY;
  c1.Radius = 10;
  cm.Region = c1;
  cm.Run();//判断是否合格
  
  if(cm.Result.ResultOfBestMatch.Color.Name == "NG")
  {
    count_ng++;
    labels[i] = new CogGraphicLabel();
    labels[i].SetXYText(c1.CenterX, c1.CenterY, "NG");
  }
  else 
  {
    count_ok++;
    labels[i] = new CogGraphicLabel();
    labels[i].SetXYText(c1.CenterX, c1.CenterY, "OK");
  }
  col.Add(labels[i]);
}
if(count_ok == 15)
{
  label.SetXYText(200, 100, "合格");
}
else
{
  label.Color = CogColorConstants.Red;
  label.SetXYText(200, 100, "缺失:" + (15 - count_ok - count_ng) + " NG:" + count_ng);
}
col.Add(label);

//最后输出显示到这个页面上

foreach(ICogGraphic item in col)
    {
      mToolBlock.AddGraphicToRunRecord(item, lastRecord, "CogImageConvertTool1.InputImage", "");
    }
