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***********************************

read_image (Image, 'bin_switch/bin_switch_1')

get_image_size (Image, Width, Height)

dev_close_window ()

dev_open_window_fit_image (Image, 0, 0, 640, 640, WindowHandle)

set_display_font (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**************************************
gen_measure_rectangle2 (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)

dev_set_draw ('margin')

dev_set_color ('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**************************

p_disp_dimensions (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)
