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 Row=270, Column=230, Phi=0, Length1=30, Length2=25, MeasureLength1=10, MeasureLength2=2;    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    Hlong Index1=0, Instance1=0;    HString GenParamName1="result_type",  GenParamValue1="all_param";    HTuple  Parameter1;    Parameter1 = metrologyModel.GetMetrologyObjectResult(Index1, Instance1, GenParamName1 , GenParamValue1);    cout << "返回的测量参数一共个数： " << Parameter1.Length() << endl;    cout << "矩形中心的y坐标值: " << (double)Parameter1[0] << "   矩形中心的x坐标值:  " << (double)Parameter1[1] << endl;    cout << "矩形的长半轴的方向角： " << (double)Parameter1[2] << "  矩形长半轴的长度： " << (double)Parameter1[3] << endl;    cout << "矩形短半轴的长度： " << (double)Parameter1[4] << endl<<endl;    //查询测量对象的结果轮廓    //参数说明：Contour返回的结果轮廓对象,  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,  Resolution指定相邻轮廓点的距离    HTuple Index2=0, Instance2=0;    double Resolution2=1.5;    HXLDCont cont2 = metrologyModel.GetMetrologyObjectResultContour(Index2, Instance2, Resolution2);    w.SetColor("red");    w.DispXld(cont2);    w.Click();    //测量模型序列化与逆序列化    HSerializedItem item = metrologyModel.SerializeMetrologyModel();    HMetrologyModel serializeModel;    serializeModel.CreateMetrologyModel();    serializeModel.DeserializeMetrologyModel(item);    //测量模型写入文件与从文件中读出    metrologyModel.WriteMetrologyModel("metrologyModel.mtr");    HMetrologyModel fileModel;    fileModel.CreateMetrologyModel();    fileModel.ReadMetrologyModel("metrologyModel.mtr");}

2.测量圆或者圆弧
