Visionpro 液位高度检测

一.项目示例

分析:

以上这种属于检测液体是否发表, 由于相机拍摄很模糊,下面我们会用到,

图像与处理工具,CogIPOneImageTool  ,和像素处理 CogPixelMapTool

二 . 原图:

三. 题目要求

液位高度检测  手动定义一条基准线(绿色线条 通过卡尺工具和createline)  测量值液位高度到基准线高度  大于130 小于110为NG

四. 解决方法

注意:我这里写的比较少,好多工具都是手搓出来的

1.工具

2.图像处理

 

3.接下来,就是我手搓的两个工具 CogCreateSegmentTool  和  CogDistanceSegmentLineTool  (这里就不给大家拉了,学习任务繁重,望理解)

 拉好之后是这个样子

4.声明

 CogGraphicCollection dt = new CogGraphicCollection();
  CogGraphicLabel label;
  CogCreateSegmentTool segment;
  CogDistanceSegmentLineTool segmentLine;

5.将拉的工具进行声明

    
    dt.Clear();
    CogPixelMapTool pixel = mToolBlock.Tools["CogPixelMapTool1"]as CogPixelMapTool;
    CogPMAlignTool pma = mToolBlock.Tools["CogPMAlignTool1"]as CogPMAlignTool;
    CogCaliperTool caliper = mToolBlock.Tools["CogCaliperTool1"]as CogCaliperTool;
    CogCreateLineTool line = mToolBlock.Tools["CogCreateLineTool1"]as CogCreateLineTool;

6.循环并创建多个卡尺

  for(int i = 0;i < pma.Results.Count;i++)
    {
      caliper.Region.CenterX = pma.Results[i].GetPose().TranslationX;
      caliper.Region.CenterY = pma.Results[i].GetPose().TranslationY;
      caliper.Run();
      

7.给卡尺的位置创建一条线段

 segment = new CogCreateSegmentTool();
      segment.InputImage = pixel.OutputImage;
      segment.Segment.StartX = caliper.Results[0].Edge0.PositionX;
      segment.Segment.StartY = caliper.Results[0].Edge0.PositionY;
      segment.Segment.EndX = caliper.Results[0].Edge0.PositionX + 20;
      segment.Segment.EndY = caliper.Results[0].Edge0.PositionY;
      segment.Run();
      segment.GetOutputSegment().Color = CogColorConstants.Purple;
      dt.Add(segment.GetOutputSegment());

8.线段连接线,找出线段到线的那段距离

segmentLine = new CogDistanceSegmentLineTool();
      segmentLine.InputImage = pixel.OutputImage;
      segmentLine.Segment = segment.GetOutputSegment();
      segmentLine.Line = line.GetOutputLine();
      segmentLine.Run();

9.判断,距离是否合格

 label = new CogGraphicLabel();
      double width = Math.Round((segmentLine.Distance),2);
      double x = caliper.Results[0].Edge0.PositionX;
      double y = caliper.Results[0].Edge0.PositionY;
      if(width > 130 || width < 110)
      {
        label.Color = CogColorConstants.Red;
        label.SetXYText(x, y -15, "NG:" + width);
      }else
      {
        label.Color = CogColorConstants.Green;
        label.SetXYText(x, y -15, "OK:" + width);
      }
      label.Font = new Font("楷体", 15);
      dt.Add(label);
      
    }  

10.最后把集合遍历出来,放在你想要放的工具页面上去

 foreach(ICogGraphic s in dt)
    {
      mToolBlock.AddGraphicToRunRecord(s, lastRecord, "CogPixelMapTool1.输出图像", "script");
    }
