*设置尺寸
set_metrology_model_image_size (MetrologyHandle, Width, Height)
*添加线模型
add_metrology_object_line_measure (MetrologyHandle, Row1, Column1, Row2, Column2, 20, 5, 1, 30, [], [], Index)
*应用测量
apply_metrology_model (Image, MetrologyHandle)
*开始找边缘，顺便把边缘上卡尺找到的所有点坐标输出在ROW,Column里面（数组形式）
get_metrology_object_measures (Contours, MetrologyHandle, 'all', 'all', Row, Column)
*Contours为卡尺， Row, Column为卡尺找到的结果值
*获取线的起点和终点坐标
get_metrology_object_result (MetrologyHandle, 'all', 'all', 'result_type', 'all_param', Parameter)
*获取找到的轮廓线
get_metrology_object_result_contour (Contour, MetrologyHandle, 'all', 'all', 1.5)
*清除
