1.gen_measure_rectangle2( : : Row, Column, Phi, Length1, Length2, Width, Height,Interpolation : MeasureHandle)
產生測量矩形句柄，控制輸入為測量矩形范圍的坐標中心，矩形長軸和水平方向夾角范圍的弧度，矩形邊長的一半，測量圖片的寬和高度，輸出為測量句柄。
2.measure_pairs(Image : : MeasureHandle, Sigma, Threshold, Transition, Select :RowEdgeFirst, ColumnEdgeFirst, AmplitudeFirst, RowEdgeSecond, ColumnEdgeSecond,AmplitudeSecond, IntraDistance, InterDistance)
抽取和矩形主軸垂直的直線，返回第一類和第二類邊緣點的行列坐標值，邊緣分類由Transition的灰度差分決定。控制輸出還有，一個邊緣對之間的距離；以及一類邊緣對相繼邊緣之間的距離。
3.image_points_to_world_plane( : : CameraParam, WorldPose, Rows, Cols, Scale : X, Y)
把像素坐標轉化到世界坐標系中的Z=0平面中的X,Y坐標。控制輸入為，相機內參數，標定的世界坐標位姿，測量單位，像素坐標，輸出為Z=0平面的X,Y坐標。
4.distance_pp( : : Row1, Column1, Row2, Column2 : Distance)
利用兩點距離公式計算兩點之間的距離。
注意用法：distance_pp (X1[0:4], Y1[0:4], X1[1:5], Y1[1:5], Distance)
5.tuple_mean( : : Tuple : Mean) 返回數組的平均值。
6.tuple_deviation( : : Tuple : Deviation) 返回數組中所有元素的標准差。
對應的HALCON單相機標定后的測量程序段如下：
1: calibrate_cameras (CalibDataID, Errors)
2: get_calib_data (CalibDataID, 'camera', 0, 'params', CamParam)
3: NumImage := 11
4: get_calib_data (CalibDataID, 'calib_obj_pose', [0, NumImage], 'pose', Pose)
5: * To take the thickness of the calibration plate into account, the z-value
6: * of the origin given by the camera pose has to be translated by the
7: * thickness of the calibration plate.
8: * Deactivate the following line if you do not want to add the correction.
9: set_origin_pose (Pose, 0, 0, 0.00075, Pose)
10: * measure the distance between the pitch lines

13: Row := (RowEdgeFirst+RowEdgeSecond)/2.0
14: Col := (ColumnEdgeFirst+ColumnEdgeSecond)/2.0

18: tuple_mean (Distance, MeanDistance)
19: tuple_deviation (Distance, DeviationDistance)
20: disp_message (WindowHandle, 'Mean distance: '+MeanDistance$'.3f'+'mm +/- '+DeviationDistance$'.3f'+'mm', 'window', 30, 150, 'yellow', 'false')
21: close_measure (MeasureHandle)
22: clear_calib_data (CalibDataID)
