Visionpro多目标找圆直径

CogCalibCheckboardTool1工具将像素转换成实际距离
CogPMAlignTool1工具抓取感兴趣图像的坐标
CogFindCircleTool1找圆

需要的中心点坐标位置

 #region Private Member Variables
  private Cognex.VisionPro.ToolBlock.CogToolBlock mToolBlock;
  CogGraphicCollection G = new CogGraphicCollection();//文本集合

将需要的圆的中心xy传到找圆工具 确定显示位置

循环显示即可
