halcon使用gen_measure_rectangle2代码

以下是Halcon中使用`gen_measure_rectangle2`函数实现矩形测量的示例代码：

#include "HalconCpp.h"
#include <iostream>

using namespace HalconCpp;
using namespace std;

int main()
{
    // 读取图像
    HImage image("test.jpg");
    // 显示图像
    DispObj(image, WindowHandle("test image"), 0, 0);

    // 定义矩形测量区域的位置和大小
    HTuple row = 100, column = 100, phi = 0, length1 = 200, length2 = 100;
    // 创建矩形测量区域
    HRegion rectangle = GenMeasureRectangle2(row, column, phi, length1, length2, image.Width(), image.Height());
    // 显示矩形测量区域
    DispObj(rectangle, WindowHandle("test image"), "blue");

    // 定义测量参数
    HTuple measureThreshold = 20, measureTransition = "positive", measureSelect = "all",
           measureInterpolation = "bicubic", measureSigma = 1.0, measureAngle = "use_polarity",
           measureSubPixel = "no_refinement", measureRoi = "no_pregeneration";

    // 执行矩形测量
    HTuple resultRow, resultColumn, resultPhi, resultLength1, resultLength2;
    GenMeasureRectangle2(rectangle, image, "first", "last", 1, measureTransition,
                         measureSelect, measureThreshold, measureRoi, measureAngle,
                         measureSubPixel, &resultRow, &resultColumn, &resultPhi,
                         &resultLength1, &resultLength2);

    // 输出测量结果
    cout << "Row: " << resultRow.D() << endl;
    cout << "Column: " << resultColumn.D() << endl;
    cout << "Phi: " << resultPhi.D() << endl;
    cout << "Length1: " << resultLength1.D() << endl;
    cout << "Length2: " << resultLength2.D() << endl;

    return 0;
}

在这个示例代码中，首先读取了一张图像，并显示在屏幕上。然后定义了矩形测量区域的位置和大小，并使用`GenMeasureRectangle2`函数创建了矩形测量区域，并将其显示在图像上。接着，定义了矩形测量的参数，并使用`GenMeasureRectangle2`函数执行矩形测量，并将测量结果保存在`resultRow`、`resultColumn`、`resultPhi`、`resultLength1`和`resultLength2`变量中。最后，将测量结果输出到控制台。

需要注意的是，本示例代码仅供参考，实际使用时需要根据具体情况进行修改。
