halcon学习之一维测量基础

创建测量矩形，获取测量句柄

gen_measure_rectangle2（）

使用句柄进行测量

measure_pos（）

修改参数Threshold

修改参数Transition

修改参数select

参数RowEdge，ColumnEdge，Distance

measure_pairs（）

修改参数Transition

修改参数Select

intraDistance与interDistance

清除句柄

close_measure（）

创建测量矩形，获取测量句柄

gen_measure_rectangle2（）

gen_measure_arc（）

使用句柄进行测量

measure_pos（）

代码

read_image (Image, 'C:/Users/Public/Documents/MVTec/HALCON-19.05-Progress/examples/images/gasket/gasket_01.png')
dev_close_window ()get_image_size (Image, Width, Height)
dev_open_window (0, 0, Width, Height, 'black', WindowHandle)
dev_display (Image)
dev_set_draw ('margin')
dev_set_line_width (2)draw_rectangle2 (WindowHandle, Row, Column, Phi, Length1, Length2)
gen_measure_rectangle2 (Row, Column, Phi, Length1, Length2, Width, Height, 'nearest_neighbor', MeasureHandle)
measure_pos (Image, MeasureHandle, 1, 30, 'all', 'all', RowEdge, ColumnEdge, Amplitude, Distance)
disp_rectangle2 (WindowHandle, Row, Column, Phi, Length1, Length2)
disp_cross (WindowHandle, RowEdge, ColumnEdge, 20, 45)

修改参数Threshold

可以看到，当threshold大于黑色与灰色的灰度值差，那么将获取不了边沿点。

修改参数Transition

可以理解为positive为增加，就是灰度从小到大的点将被选择。

修改参数select

参数RowEdge，ColumnEdge，Distance

measure_pairs（）

代码

read_image (Image, 'C:/Users/Public/Documents/MVTec/HALCON-19.05-Progress/examples/images/gasket/gasket_01.png')
dev_close_window ()get_image_size (Image, Width, Height)
dev_open_window (0, 0, Width, Height, 'black', WindowHandle)
dev_display (Image)
dev_set_draw ('margin')
dev_set_line_width (2)draw_rectangle2 (WindowHandle, Row, Column, Phi, Length1, Length2)
gen_measure_rectangle2 (Row, Column, Phi, Length1, Length2, Width, Height, 'nearest_neighbor', MeasureHandle)measure_pairs (Image, MeasureHandle, 1, 30, 'all', 'all', RowEdgeFirst, ColumnEdgeFirst, AmplitudeFirst, RowEdgeSecond, ColumnEdgeSecond, AmplitudeSecond, IntraDistance, InterDistance)

使用disp_cross（）绘制得出的结果。
