First, the length of the leads is measured, then, their width and distance from each other. First, read in the image and initialize the programRead_image (Image, icpin)*取得图像第一通道的指针,同时得到图像宽度高度*Get_image_pointer1 (Image, Pointer, Type, Width, Height)*get_image_pointer1 ( Image : : : Pointer, Type, Width, Height ) ；获得图像的数据。如：类型(= 字节, ,uint2 int2 等等) 和图像的尺寸( 的宽度和高度)Dev_close_window ()dev_close_window ( : : : ) 关闭活跃的图形窗口。Dev_open_window_fit_image (Image, 0, 0, 509, 509, WindowHandle)设置窗口自适应图片，获得句柄Set_display_font (WindowHandle, 14, mono, true, false)内部程序，设置字体dev_display (Image)*显示图像如下：* Define and display the rectangular ROIs within which the edges will be detected /ROI设置Dev_set_draw (margin)Dev_se_tline_width (3)Row := 55RowBottom := 955Column := 200Phi := rad(-90)Length1 := 50Length2 := 35devsetcolor (gray)gen_rectangle2 (Rectangle, Row, Column, Phi, Length1, Length2)gen_rectangle2 (Rectangle, RowBottom, Column, Phi, Length1, Length2)创建ROI的矩形显示区域 *测量位置如绿色矩形所示下:*Disp_continue_message (WindowHandle, black, true)显示继续信息stop () Create a measure object for the ROI at the top of the image.*获取一阶灰度剖面图的插值方法，测量矩形框与图像坐标系之间有角度时生效*Interpolation := nearest_neighbor*生成测量矩形框,先测上部*Gen_measure_rectangle2 (Row, Column, Phi, Length1, Length2, Width, Height, Interpolation, MeasureHandle) Determine all edges and calculate the lead height at the top of the image/垂直与矩形的直线边缘的提取。Sigma := 1.0Threshold := 30Transition := allSelect := all*进行测量*measure_pos (Image, MeasureHandle, Sigma, Threshold, Transition, Select, RowEdge, ColumnEdge, Amplitude, Distance)提取与矩形或环状弧垂直的直线边缘。LeadLength1 := Distance Display the resultsdevsetcolor (white)*将测量结果画出*disp_line (WindowHandle, RowEdge, ColumnEdge-Length2, RowEdge, ColumnEdge+Length2)disp_message (WindowHandle, Lead Length: +LeadLength1$.2f, window, RowEdge1+40, ColumnEdge1+100, yellow, false)程序写入文本信息 Shift the measure object and determine the lead height at the bottom of the image*转移测量框至新的参考坐标点,及测量下部*translate_measure (MeasureHandle, RowBottom, Column)*进行测量*measure_pos (Image, MeasureHandle, Sigma, Threshold, Transition, Select, RowEdge, ColumnEdge, Amplitude, Distance)LeadLength2 := Distance Display the resultsdevsetcolor (white) *将测量结果画出*disp_line (WindowHandle, RowEdge, ColumnEdge-Length2, RowEdge, ColumnEdge+Length2)disp_message (WindowHandle, Lead Length: +LeadLength2$.2f, window, 360, ColumnEdge1+100, red, false) Close the measureclose_measure (MeasureHandle)清除一个测试对象。Disp_continue_message (WindowHandle, black, true)等待用户操作是否继续stop () Now, define and display a rectangular ROI perpendicular to the leads and create the measuredev_display (Image)Row := 47Column := 485Phi := 0Length1 := 420Length2 := 8Interpolation := nearest_neighbordevsetcolor (black) *创建新的测量矩形ROI，如图蓝色矩形：*gen_rectangle2 (Rectangle, Row, Column, Phi, Length1, Length2)创建ROI矩形gen_measure_rectangle2 (Row, Column, Phi, Length1, Length2, Width, Height, Interpolation, MeasureHandle)垂直与矩形的直线边缘的提取。 Determine all edge pairs that have a negative transition, i.e., edge pairs that enclose dark regions.Sigma := 1.0Threshold := 30Transition := negativeSelect := all*进行测量计算并显示结果*measure_pairs (Image, MeasureHandle, Sigma, Threshold, Transition, Select, RowEdgeFirst, ColumnEdgeFirst, AmplitudeFirst, RowEdgeSecond, ColumnEdgeSecond, AmplitudeSecond, IntraDistance, InterDistance)提取测量与矩形或环状弧垂直的直线边缘。dispcontinuemessage (WindowHandle, black, true)stop ()devsetcolor (white)disp_line (WindowHandle, RowEdgeFirst, ColumnEdgeFirst, RowEdgeSecond, ColumnEdgeSecond)avgLeadWidth := sum(IntraDistance)/|IntraDistance|avgLeadDistance := sum(InterDistance)/|InterDistance|numLeads := |IntraDistance|disp_message (WindowHandle, Number of Leads: +numLeads, window, 200, 100, yellow, false)disp_message (WindowHandle, Average Lead Width: +avgLeadWidth$.2f, window, 260, 100, yellow, false)disp_message (WindowHandle, Average Lead Distance: +avgLeadDistance$.2f, window, 320, 100, yellow, false)信息显示dispcontinuemessage (WindowHandle, black, true)dispcontinuemessage (WindowHandle, black, true)stop () Zoom in to visualize the measurement results in more detail.
