1.核心算子

measure_pos — Extract straight edges perpendicular to a rectangle or annular arc.   提取垂直于矩形或环形圆弧的直边

measure_pairs — Extract straight edge pairs perpendicular to a rectangle or annular arc　　提取垂直于矩形或环形圆弧的直边对；将返回具有明-暗-亮过渡的边缘对或具有深-明-暗过渡的边缘对

measure_pairs的提取算法与measure_pos相同

2.测试

measure_pairs (Fuse, MeasureHandle, 1, 10, 'positive', 'first', RowEdgeFirst, ColumnEdgeFirst, AmplitudeFirst, RowEdgeSecond, ColumnEdgeSecond, AmplitudeSecond, IntraDistance, InterDistance)

对应效果：

measure_pairs (Fuse, MeasureHandle, 1, 10, 'negative', 'first', RowEdgeFirst, ColumnEdgeFirst, AmplitudeFirst, RowEdgeSecond, ColumnEdgeSecond, AmplitudeSecond, IntraDistance, InterDistance)

对应效果如下：

 

measure_pairs (Fuse, MeasureHandle, 1, 10, 'negative', 'first', RowEdgeFirst, ColumnEdgeFirst, AmplitudeFirst, RowEdgeSecond, ColumnEdgeSecond, AmplitudeSecond, IntraDistance, InterDistance)

对应效果如下：
