Visonpro检测是否有缺齿

一、效果展示

二、上面是原展开工具CogPolarUnwrapTool； 第二种方法： 用Blob 和 CogCopyRegionTool

 

三、 用预处理工具  加减常数，让图片变得更亮点

四、圆展开工具   五、模板匹配

六、代码分解 1.创建集合和文子显示工具 CogGraphicCollection dt = new CogGraphicCollection(); CogGraphicLabel Label; 2.加载工具，并实例化一个List集合 dt.Clear(); CogPolarUnwrapTool polar = mToolBlock.Tools["CogPolarUnwrapTool1"]as CogPolarUnwrapTool; CogPMAlignTool pma = mToolBlock.Tools["CogPMAlignTool1"]as CogPMAlignTool; List<double> listX = new List<double>(); 3.定义图标中的坐标吗，添加集合，排序 double total = 0; double x, y; for(int i = 0;i < pma.Results.Count;i++) { listX.Add(pma.Results[i].GetPose().TranslationX); total += pma.Results[i].GetPose().TranslationY; } y = total / pma.Results.Count; listX.Sort(); 4.进行传参，找出之前的x和y坐标系，并用参数接收是否存在缺失 int a = 0; for(int i = 0;i < listX.Count - 1;i++) { if((listX[i + 1] - listX[i]) > 50) { x = (listX[i + 1] + listX[i]) / 2; y = total / pma.Results.Count; double lastx,lasty; polar.RunParams.GetInputPointFromOutputPoint(polar.InputImage, polar.Region, x, y, out lastx, out lasty); dt.Add(Create(lastx, lasty)); a++; } } 5.进行判断是否缺失 Label = new CogGraphicLabel(); if(a > 0){ Label.SetXYText(100, 100, "缺失"+a); Label.Color = CogColorConstants.Red; Label.Font = new Font("楷体", 30); dt.Add(Label); }else{ Label.SetXYText(100, 100, "OK"); Label.Color = CogColorConstants.Green; Label.Font = new Font("楷体", 30); dt.Add(Label); } 6.将上面传入圆展开的x，y坐标，进行创建圆 private CogCircle Create(double x, double y) { CogCircle co = new CogCircle(); co.CenterX = x; co.CenterY = y; co.Radius = 20; co.LineWidthInScreenPixels = 6; co.Color = CogColorConstants.Red; dt.Add(co); return co; } 7.输出 for(int i = 0;i < dt.Count;i++) { mToolBlock.AddGraphicToRunRecord(dt[i], lastRecord, "CogIPOneImageTool1.InputImage", ""); } 8.代码All #region namespace imports using System; using System.Collections; using System.Collections.Generic; using System.Drawing; using System.IO; using System.Windows.Forms; using Cognex.VisionPro;

​​​​​​​注意事项： 方法的作用：该方法的主要作用是将输出图像中的坐标映射回输入图像中的坐标，通常用于图像变换后的逆向坐标查找。参数检查：确保 polar.InputImage 和 polar.Region 已正确初始化，并且 x, y 坐标在有效的范围内。返回值：lastx 和 lasty 是通过 out 参数返回的，因此调用后可以直接使用这两个变量获取转换后的坐标。 八、第二种方法 1.定义值

2. 工具展示

3. Blob设置

4.CogCopyReigonTool设置 添加终端链接  

 

 5.CogBlob覆盖后设置
