跟我学机器视觉-HALCON学习例程中文详解-开关引脚测量

• This example program demonstrates the basic usage of a measure object.

• Here, the task is to determine the width of and the distance between the

• pins of a switch.

*本例程演示了如何使用测量工具测量开关的引脚宽度和间距

• First, read in the image and initialize the program.

*******打开图像**********

readimage (Image, ‘binswitch/binswitch1‘)

getimagesize (Image, Width, Height)

devclosewindow ()

devopenwindowfitimage (Image, 0, 0, 640, 640, WindowHandle)

setdisplayfont (WindowHandle, 14, ‘mono‘, ‘true‘, ‘false‘)

dev_display (Image)

*显示图片如下

• Define the rectangular ROI within which the edges will be detected

  • and create the measure.

Row := 390

Column := 380

Phi := rad(-60)

Length1 := 60

Length2 := 10

Interpolation := ‘nearest_neighbor‘

*******生成测量矩形ROI************ genmeasurerectangle2 (Row, Column, Phi, Length1, Length2, Width, Height, Interpolation, MeasureHandle)

*测量矩形位置尺寸如下：

• Determine all edge pairs that have a negative transition, i.e., edge pairs

• that enclose dark regions.

Sigma := 0.9

Threshold := 12

Transition := ‘negative‘

Select := ‘all‘

***********测量边缘对*********

measure_pairs (Image, MeasureHandle, Sigma, Threshold, Transition, Select, RowEdgeFirst, ColumnEdgeFirst, AmplitudeFirst, RowEdgeSecond, ColumnEdgeSecond, AmplitudeSecond, IntraDistance, InterDistance)

• Visualize the results

dev_display (Image)

devsetdraw (‘margin‘)

devsetcolor (‘black‘)

**显示测量矩形ROI***************

gen_rectangle2 (Rectangle, Row, Column, Phi, Length1, Length2)

显示测量的边缘对的尺寸,length1要用ROI的宽度**********

pdispdimensions (RowEdgeFirst, ColumnEdgeFirst, RowEdgeSecond, ColumnEdgeSecond, IntraDistance, InterDistance, Phi, Length2, WindowHandle)

*结果如下：

• Free the memory that has been allocated for the measure. close_measure (MeasureHandle)
