1.测量矩形

void test2DMetrologyRect()
{
    //创建一个需要用来测量几何图形的数据结构
    HMetrologyModel metrologyModel;
    metrologyModel.CreateMetrologyModel();

    HImage image("fabrik.png");
    Hlong width, height;
    image.GetImageSize(&width,&height);

    HWindow w(0, 0,width, height);
    w.DispImage(image);
    w.Click();
    //设置被测量图像的尺寸大小
    metrologyModel.SetMetrologyModelImageSize(width, height);

    //增加一个矩形到测量模型
    //参数说明： MetrologyHandle指测量模型的句柄, Row为矩形中心的y坐标值, Column为矩形中心的x坐标值, Phi为矩形的长半轴的方向,
    //Length1为矩形长半轴的长度, Length2为矩形短半轴的长度,MeasureLength1相对于长半轴垂直边界的检测区域一半长度, 
    //MeasureLength2相对于短半轴垂直边界的检测区域一半长度, MeasureSigma高斯平滑用到的参数, MeasureThreshold最小边界的振幅, 
    // GenParamName指定通用参数的名称, GenParamValue指定通用参数的值,Index指定创建测量对象的索引

    HTuple MeasureSigma = 1, MeasureThreshold = 30, GenParamName = HTuple(), GenParamValue = HTuple(), Index;
    Index = metrologyModel.AddMetrologyObjectRectangle2Measure(Row, Column, Phi, Length1, Length2, MeasureLength1, MeasureLength2, MeasureSigma, MeasureThreshold, GenParamName, GenParamValue);

    //对一个图像进行测量并且匹配指定的测量对象
    metrologyModel.ApplyMetrologyModel(image);

    //获得测量模型获得的测量结果
    //参数说明： MetrologyHandle测量模型的句柄, Index指定测量对象的下标, Instance指定返回的测量结果实例的类型,
    //GenParamName指定通用参数的名称, GenParamValue指定通用参数的值,Parameter返回的结果

2.测量圆或者圆弧

    w.DispImage(image);
    w.Click();

    //设置被测量图像的尺寸大小

    Index = metrologyModel.AddMetrologyObjectCircleMeasure(Row, Column, Radius, MeasureLength1, MeasureLength2, MeasureSigma, MeasureThreshold, GenParamName, GenParamValue);

    //查询指定的模型轮廓的位置
    //参数说明：Contour为返回的轮廓, Index指定测量模型的下标, Resolution指定轮廓点之间的距离
    HTuple Index1=0;
    double Resolution1 = 1.5;
    HXLDCont cont1 = metrologyModel.GetMetrologyObjectModelContour(Index1, Resolution1);
    w.SetColor("yellow");
    w.DispXld(cont1);
    w.Click();

    //对一个图像进行测量并且匹配指定的测量对象
