hdevelop 中 halcon使用gen_measure_rectangle2代码

在HDevelop中使用`gen_measure_rectangle2`函数实现矩形测量，可以按照以下步骤进行：

1. 打开HDevelop开发环境，创建一个新的程序。

2. 读取图像并显示：

read_image(Image, 'test.jpg')
dev_set_window ('fit')
dev_display(Image)

3. 创建矩形测量区域：

create_measure_rectangle2(Row, Column, Phi, Length1, Length2, ImageWidth, ImageHeight, &MeasureHandle)
dev_display(MeasureHandle)

其中，`Row`和`Column`表示矩形中心点的行列坐标，`Phi`表示矩形相对于X轴的旋转角度，`Length1`和`Length2`分别表示矩形的长和宽，`ImageWidth`和`ImageHeight`分别表示图像的宽和高，`MeasureHandle`表示测量区域的句柄。

4. 定义测量参数：

MeasureThreshold := 20
MeasureTransition := 'positive'
MeasureSelect := 'all'
MeasureInterpolation := 'bicubic'
MeasureSigma := 1.0
MeasureAngle := 'use_polarity'
MeasureSubPixel := 'no_refinement'
MeasureRoi := 'no_pregeneration'

5. 执行矩形测量：

gen_measure_rectangle2(MeasureHandle, Image, 'first', 'last', 1, MeasureTransition, MeasureSelect, MeasureThreshold, MeasureRoi, MeasureAngle, MeasureSubPixel, &ResultRow, &ResultColumn, &ResultPhi, &ResultLength1, &ResultLength2)

其中，`Image`表示输入图像，`ResultRow`、`ResultColumn`、`ResultPhi`、`ResultLength1`和`ResultLength2`分别表示测量结果中矩形中心点的行列坐标、旋转角度、长和宽。

6. 输出测量结果：

disp_message(WindowHandle, 'Row: '+ResultRow.ToString(), 'window', 12, 12, 'black', 'true')
disp_message(WindowHandle, 'Column: '+ResultColumn.ToString(), 'window', 24, 12, 'black', 'true')
disp_message(WindowHandle, 'Phi: '+ResultPhi.ToString(), 'window', 36, 12, 'black', 'true')
disp_message(WindowHandle, 'Length1: '+ResultLength1.ToString(), 'window', 48, 12, 'black', 'true')
disp_message(WindowHandle, 'Length2: '+ResultLength2.ToString(), 'window', 60, 12, 'black', 'true')

其中，`WindowHandle`表示显示结果的窗口句柄。

完整代码如下：

read_image(Image, 'test.jpg')
dev_set_window ('fit')
dev_display(Image)

create_measure_rectangle2(Row, Column, Phi, Length1, Length2, ImageWidth, ImageHeight, &MeasureHandle)
dev_display(MeasureHandle)

MeasureThreshold := 20
MeasureTransition := 'positive'
MeasureSelect := 'all'
MeasureInterpolation := 'bicubic'
MeasureSigma := 1.0
MeasureAngle := 'use_polarity'
MeasureSubPixel := 'no_refinement'
MeasureRoi := 'no_pregeneration'

gen_measure_rectangle2(MeasureHandle, Image, 'first', 'last', 1, MeasureTransition, MeasureSelect, MeasureThreshold, MeasureRoi, MeasureAngle, MeasureSubPixel, &ResultRow, &ResultColumn, &ResultPhi, &ResultLength1, &ResultLength2)

disp_message(WindowHandle, 'Row: '+ResultRow.ToString(), 'window', 12, 12, 'black', 'true')
disp_message(WindowHandle, 'Column: '+ResultColumn.ToString(), 'window', 24, 12, 'black', 'true')
disp_message(WindowHandle, 'Phi: '+ResultPhi.ToString(), 'window', 36, 12, 'black', 'true')
disp_message(WindowHandle, 'Length1: '+ResultLength1.ToString(), 'window', 48, 12, 'black', 'true')
disp_message(WindowHandle, 'Length2: '+ResultLength2.ToString(), 'window', 60, 12, 'black', 'true')
