方法原型：

measure_pairs(Image : : MeasureHandle, Sigma, Threshold, Transition, Select : RowEdgeFirst, ColumnEdgeFirst, AmplitudeFirst, RowEdgeSecond, ColumnEdgeSecond, AmplitudeSecond, IntraDistance, InterDistance)

解釋:

measure_pairs:用于提取垂直于矩形或環(huán)形弧長(zhǎng)軸的直邊對(duì).

Image：輸入待檢測(cè)圖片；

MeasureHandle:一個(gè)測(cè)量句柄=>gen_measure_rectangle2

Sigma:高斯濾波的參數(shù):

Threshold:是對(duì)高斯濾波曲線的一階導(dǎo)數(shù)設(shè)置的閾值(幅值)

Transition:'all', 'all_strongest', 'negative', 'negative_strongest', 'positive', 'positive_strongest'

Select:'all' 'first' 'last'

RowEdgeFirst,第一個(gè)邊的row集合

ColumnEdgeFirst,第一個(gè)邊的Column集合?

AmplitudeFirst:第一個(gè)邊的幅值

RowEdgeSecond:第二個(gè)邊的row集合

ColumnEdgeSecond：第二個(gè)邊的Column集合

AmplitudeSecond:第二個(gè)邊的幅值

IntraDistance:邊隊(duì)內(nèi)距離

InterDistance:連續(xù)邊隊(duì)之間距離

相關(guān)方法:

gen_rectangle2 gen_measure_rectangle2 close_measure( : : MeasureHandle : ) *刪除MeasureHandle對(duì)象，并釋放對(duì)象的內(nèi)存占用。

dev_update_off () dev_clear_window() *設(shè)置繪制方式 dev_set_draw ('margin') read_image (Image, 'C:/Users/Public/Documents/MVTec/HALCON-18.11-Progress/examples/images/printer_chip/printer_chip_01.png') get_image_size (Image, Width, Height) rgb1_to_gray (Image, GrayImage) Row1:=160 Column1:=320 Length1:=900 Length2:=10 Phi:=rad(0) gen_rectangle2 (Rectangle, Row1, Column1, Phi, Length1, Length2) dev_display (GrayImage) dev_display (Rectangle) gen_measure_rectangle2 (Row1,Column1,Phi,Length1,Length2,Width,Height,'nearest_neighbor', MeasureHandle) measure_pairs (GrayImage, MeasureHandle, 1,100, 'positive', 'all', RowEdgeFirst, ColumnEdgeFirst, AmplitudeFirst, RowEdgeSecond, ColumnEdgeSecond, AmplitudeSecond, IntraDistance, InterDistance) count:=|IntraDistance| gen_rectangle1 (Rectangle1, RowEdgeSecond[1], ColumnEdgeSecond[1], RowEdgeSecond[1]+200, ColumnEdgeSecond[1]+10) dev_display (Rectangle1) dev_disp_text (count+'個(gè)元素', 'window', 123, 500,'red', [], [])
