直線檢測(cè)大體可分為從上而下以及從下而上兩種模式硅急。
1圣猎。從上而下的直線檢測(cè)模式典型代表Hough變換逝钥，將直線由坐標(biāo)空間變換為參數(shù)空間，進(jìn)而投票檢測(cè)直線
2糕再。從下而上的直線檢測(cè)模式有鏈碼跟蹤量没，以及相位編組等。LSD[1]( "LSD: A Fast Line Segment Detector with a False Detection Control" by Rafael Grompone von Gioi, Jeremie Jakubowicz, Jean-Michel Morel, and Gregory Randall, IEEE Transactions on Pattern Analysis and Machine Intelligence, vol. 32, no. 4, pp. 722-732, April, 2010.)也是一種優(yōu)秀的短直線檢測(cè)方法(LSD: A Fast Line Segment Detector with a False Detection Control)
3突想。從下而上的直線檢測(cè)方法多檢測(cè)到短線段殴蹄，然后將短線段聚類形成長(zhǎng)直線究抓，戴激光等[2]提出的權(quán)重投影模型是應(yīng)該不錯(cuò)的聚類方法
