跟我学机器视觉-HALCON学习例程中文详解-FUZZY检测用于开关引脚测量 * This example program demonstrates the basic usage of a fuzzy measure object. * Here, the task is to determine the width of and the distance between the * pins of a switch. * * First, read in the image and initialize the program. ***********************打开图像，获取图像宽度，高度*********************** read_image (Image, 'bin_switch/bin_switch_2') get_image_size (Image, Width, Height) p_reopen_window_fit (0, 0, Width, Height, 640, WindowHandle) p_set_font (WindowHandle) dev_display (Image) ************************显示图像如下：注意中间引脚反光**********************
* Define the rectangular ROI within which the edges will be detected
* and create the measure.
Row := 290
Column := 170
Phi := rad(-130)
Length1 := 60
Length2 := 10
Interpolation := 'nearest_neighbor'
*************************生成测量矩形ROI，注意角度为-130度*********************
gen_measure_rectangle2 (Row, Column, Phi, Length1, Length2, Width, Height, Interpolation, MeasureHandle)
*
* Determine all edge pairs that have a negative transition, i.e., edge pairs
* that enclose dark regions.
Sigma := 0.9
Threshold := 10
Transition := 'all'
Select := 'all'
**************进行测量，并显示检测结果，可以看出，中间的引脚检测结果不正确****

* Visualize the results

***************************放大后图像如下**************************************
*******************************检测框角度为-130时，Threshold怎么变都不行，*******************************Transition改为*****negative_strongest也不行*******
*****************Any question， Contact Q： 1613985351*******************
************************解决方法一：检测角度为50度时，检测结果正常**********
********解决方法二：使用FUZZY检测,已知引脚宽度为9个像素左右****************

* Due to the reflections on the middle pin, its width cannot be determined correctly.
*
* As we know that the pins appear approximately 9 pixels wide, it is very easy to expand the measure to a
* fuzzy measure that will only return pairs that have a width of approximately the given size.
*
* First, create a fuzzy function that returns 1.0 for the given pair size and 0.0 for values that
* deviate more than 2 pixels from the given pair size.
*************************创建SIZE范围函数**********************************
create_funct_1d_pairs ([7,9,11], [0.0,1.0,0.0], SizeFunction)
*
* Then, expand the measure to a fuzzy measure that will return only pairs of approximately the given size.
SetType := 'size'
*************************创建测量句柄****************************************
set_fuzzy_measure (MeasureHandle, SetType, SizeFunction)
*
************设为Fuzzy检测时，中间引脚找到第一条边时，再找另一条边，宽度必须在8-10之间，因此中间那条边界被忽略，刚好找的正确边缘，否则找不到****************
* Finally, determine all edge pairs that have a negative transition and approximately the given size.
Sigma := 0.9
AmpThresh := 12
FuzzyThresh := 0.5
Transition := 'negative'
Select := 'all'
******************************fuzzy检测，使用创建的测量句柄*******************
fuzzy_measure_pairs (Image, MeasureHandle, Sigma, AmpThresh, FuzzyThresh, Transition, RowEdgeFirst, ColumnEdgeFirst, AmplitudeFirst, RowEdgeSecond, ColumnEdgeSecond, AmplitudeSecond, RowEdgeCenter, ColumnEdgeCenter, FuzzyScore, IntraDistance, InterDistance)
********************将检测结果显示出来，可以看出现在测量结果正确了*************
* And again, visualize the results
