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

七、polar.RunParams.GetInputPointFromOutputPoint

该方法用于输出图像中的坐标 (x, y) 转换为输入图像中的坐标 (lastx, lasty)

  • polar.InputImage 是输入图像对象
  • polar.Region 可能是指定的处理区域
  • x, y 是输出图像中的坐标
  • out lastx, out lasty 是输出参数，表示转换后的输入图像中的坐标。

​​​​​​​polar.RunParams.GetInputPointFromOutputPoint(

  1. polar.InputImage, // 输入图像

  2. polar.Region, // 处理区域

  3. x, // 输出图像中的X坐标

  4. y, // 输出图像中的Y坐标

  5. out lastx, // 输出：对应的输入图像中的X坐标

  6. out lasty // 输出：对应的输入图像中的Y坐标 );

​​​​​​​注意事项：

  1. 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。
  2. 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。
  3. 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
