本文提出的機器視覺系統(tǒng)包括模擬鋼軌探傷作業(yè)平臺、高速線陣相機、輔助光源和處理主機。軌道鋼軌道通常由兩條平行的鋼軌組成，鋼軌固定放在軌枕上，軌枕之下為路碴；以鋼鐵制成的路軌，可以比其它物料承受更大的重量。軌枕亦稱枕木，或路枕，功用是把鋼軌的重量分開散布，和保持路軌固定，維持路軌的軌距。系統(tǒng)能夠獲取高速運動的鋼軌表面圖像并進行缺點提取、特征識別和參數(shù)計算等操作，缺點圖像與識別結(jié)果通過軟件的人機界面顯示 </p> <p> 鋼軌表面缺點主要分為兩種類型:表面裂縫和滾動接觸疲勞磨損。鋼軌對鋼的要求比其它的應用都為高。同樣的小瑕疵，在建筑物使用的鋼筋內(nèi)出現(xiàn)可能不會產(chǎn)生任何問題；但在鐵路鋼軌出現(xiàn)則隨時會導致路軌斷裂而引致列車出軌。疲勞磨損主要表現(xiàn)形式有兩種，包括軌頭掉塊和軌頭波紋磨損。鋼軌表面疲勞磨損不僅影響超聲波探傷技術(shù)的準確度，某些特殊位置如軌頭測量角周圍的磨損，還可能向下發(fā)展演變成危險更大的內(nèi)部核傷.
