Halcon一維測量官方案例解析
下面的例子簡要介紹瞭如何使用HALCON的一維測量工具。最長的部分是預處理和後處理；測量自己只包括兩個操做符調用。dom
測量保險絲-fuse
預處理主要是測量線的生成。在示例程序中，這個步驟是經過將測量對象的參數分配給變量來完成的。ide
read_image (Fuse, 'fuse') Row := 297 Column := 545 Length1 := 80 Length2 := 10 Angle := rad(90) gen_rectangle2 (ROI, Row, Column, Angle, Length1, Length2)
如今經過將測量對象應用到圖像上進行實際測量。參數的選擇使得暗區周圍的邊緣被分爲兩組線段，結果返回邊緣的位置和兩組線段的寬度和距離。函數
measure_pairs (Fuse, MeasureHandle, 1, 1, 'negative', 'all', RowEdgeFirst, ColumnEdgeFirst, AmplitudeFirst, RowEdgeSecond, ColumnEdgeSecond, AmplitudeSecond, IntraDistance, InterDistance)
最後生成一個帶有測量線參數的區域，並將邊緣位置轉換爲短XLD等值線來顯示結果。工具
for i := 0 to |RowEdgeFirst| - 1 by 1
gen_contour_polygon_xld (EdgeFirst, [-sin(Angle + rad(90)) * Length2 + RowEdgeFirst[i],-sin(Angle - rad(90)) * Length2 + RowEdgeFirst[i]], [cos(Angle + rad(90)) * Length2 + ColumnEdgeFirst[i],cos(Angle - rad(90)) * Length2 + ColumnEdgeFirst[i]])

測量金屬鑄造部件-measure_arc
本例是檢測鑄件倒角後拉長孔之間的距離。爲了達到最好的精度，建議使用背光與遠心鏡頭相結合的方式，而不是圖中的設置。
這個任務能夠經過使用帶有圓形測量ROI的測量工具輕鬆解決。ROI的中心被放置在鑄件的中心；半徑設置爲拉長孔與中心的距離。rest

使用模糊測量法測量集成電路-fuzzy_measure_pin
本例是測量IC的引線寬度和引線距離。本例中的照明條件至關困難，形成了每一個引線都有四個邊緣可見。模糊規則就是用於將測量限制在正確的（外）引線上。對象

測量可移動的IC的引線-pm_measure_board
本例的任務是測量可移動的芯片引線的位置。 因爲芯片能夠出如今不一樣的位置和角度，用於測量的感興趣的區域必須對齊。
在這種狀況下，經過使用基於形狀的匹配搜索芯片上的印刷字符來實現對準。

找到印刷品後，ROI的位置將相對於印刷字符的位置進行幾何變換。
find_shape_model (ImageCheck, ModelID, 0, rad(360), 0.7, 1, 0.5, 'least_squares', 4, 0.7, RowCheck, ColumnCheck, AngleCheck, Score) hom_mat2d_identity (HomMat2DIdentity) hom_mat2d_translate (HomMat2DIdentity, RowCheck, ColumnCheck, HomMat2DTranslate) hom_mat2d_rotate (HomMat2DTranslate, AngleCheck, RowCheck, ColumnCheck, HomMat2DRotate) affine_trans_pixel (HomMat2DRotate, Rect1Row, Rect1Col, Rect1RowCheck, Rect1ColCheck)
而後，建立測量工具並應用測量。
gen_measure_rectangle2 (Rect1RowCheck, Rect1ColCheck, AngleCheck, RectLength1, RectLength2, Width, Height, 'bilinear', MeasureHandle1) measure_pairs (ImageCheck, MeasureHandle1, 2, 90, 'positive', 'all', RowEdgeFirst1, ColumnEdgeFirst1, AmplitudeFirst1, RowEdgeSecond1, ColumnEdgeSecond1, AmplitudeSecond1, IntraDistance1, InterDistance1)
源程序
* 這個示例程序展現瞭如何使用模式匹配與形狀模型來定位一個對象。 此外，它還展現瞭如何使用檢測到的物體位置和旋轉來構建檢測任務的ROI。在這個例子中，IC上的印刷字符被用來尋找IC。 從找到的位置和旋轉，構建兩個測量矩形來測量IC引線之間的間距。 因爲打光的緣故，引線在幾個位置和旋轉處的飽和灰度值爲255，這擴大了引線的實際寬度，減少了引線之間的間距。

測量IC-measure_pin
本例的任務是檢查集成電路的主要尺寸。
第一步，測量每一個引線的範圍和引線之間的距離。爲此，定義了一個包含引線的矩形用來生成測量對象。這是用來提取垂直於矩形主軸線的直邊對。
gen_measure_rectangle2 (Row, Column, Phi, Length1, Length2, Width, Height, 'nearest_neighbor', MeasureHandle) measure_pairs (Image, MeasureHandle, 1.5, 30, 'negative', 'all', RowEdgeFirst, ColumnEdgeFirst, AmplitudeFirst, RowEdgeSecond, ColumnEdgeSecond, AmplitudeSecond, PinWidth, PinDistance)
從提取的直邊對中，得出引線的數量、平均寬度和它們之間的平均距離。
avgPinWidth := sum(PinWidth) / |PinWidth| avgPinDistance := sum(PinDistance) / |PinDistance| numPins := |PinWidth|
第二部分顯示測量工具。儘管每根引線的寬度只有幾個像素，導線的長度是能夠肯定的。爲此，一個基於包含IC兩邊相對引線的矩形的測量對象生成了。第一個和第二個邊緣之間的距離是上引線的長度，第三個和第四個邊緣之間的距離是下引線的長度。
