C#圆形卡尺测量程序基于halcon
废话不多说上源码
觉得帖子有用给点个赞哈
先来个效果图
下边的是源码，自己新建一个文件粘贴进去，包含到您现在的项目 中。这串源码后边是使用方法。

接下来介绍使用方法
//new个CircleMeasure的对象出来
public CircleMeasure mCircleMeasure = new CircleMeasure();
//卡尺圆形测量数据初始化
try
{
mCircleMeasure.CircleINFOSet(0, 0, 50, 0, 2 * 3.14, "positive");
mCircleMeasure.MetrologyINFOSet(20,20,30,5,"measure_distance",1,0);
}
catch { }
开始进行测量
//定义各个需要的变量
HTuple outR = null, outC = null;
HTuple hv_Row = null, hv_Column = null, hv_Radius = null;
HTuple hv_Row11 = null, hv_Column11 = null, hv_Row12 = null, hv_Column12 = null, hv_Angle1 = null, hv_Angle2 = null;
HXLDCont m_MeasureXLD = new HXLDCont();
//LeftUpCamImageDisplay是halcon显示图像窗口控件名称
LeftUpCamImageDisplay.HalconWindow.SetColor("red");
LeftUpCamImageDisplay.HalconWindow.SetDraw("margin");
//[DrawCircleMod介绍](https://blog.csdn.net/cashmood/article/details/99756580)
HOperatorSet.DrawCircleMod(LeftUpCamImageDisplay.HalconWindow,1296 ,972 ,140 ,out hv_Row, out hv_Column, out hv_Radius);
//设置测量参数
mCircleMeasure.CircleINFOSet(hv_Row, hv_Column, hv_Radius, hv_Angle1, hv_Angle2, "positive");
mCircleMeasure.MetrologyINFOSet(hv_Radius / 5, hv_Radius / 50, 30, 5, new HTuple(("measure_distance")),
(new HTuple(10)), 0);
mCircleMeasure.MeasureCircle(LeftUpCamCurrentImg, mCircleMeasure.m_CircleInfo, mCircleMeasure.m_MetrologyInfo, out mCircleMeasure.m_OutCircleInfo, out outR, out outC, out m_MeasureXLD);
//显示测量结果
LeftUpCamImageDisplay.HalconWindow.DispObj(LeftUpCamCurrentImg);
LeftUpCamImageDisplay.HalconWindow.SetColor("blue");
LeftUpCamImageDisplay.HalconWindow.SetDraw("margin");
m_MeasureXLD.DispObj(LeftUpCamImageDisplay.HalconWindow);
LeftUpCamImageDisplay.HalconWindow.SetTposition(50, 10);
LeftUpCamImageDisplay.HalconWindow.WriteString(" CenterRow:" + mCircleMeasure.m_OutCircleInfo.Row_center.ToString() + " CenterCol:" + mCircleMeasure.m_OutCircleInfo.Column_center.ToString() + " Radius::" + mCircleMeasure.m_OutCircleInfo.Radius.ToString());
