parallel at distance 中文意思是什麼
parallel at distance
解釋
從指定平面偏置距離-
The distance between parallel cables is at least 0. 2 m.
兩根平行的傳爆線間距離不小於02米。 -
" close - up performance of the summicron - m is on the same level as the performance at infinity setting ( actually infinity is that distance where the incoming light rays are parallel to the optical axis
近攝表現與無窮遠時相當（事實上，無窮遠處的光線是平行光軸入射的.對多數鏡頭而言，大約100倍焦距的物距時，入射光滿足這一條件） -
The distance between parallel cables is at least 0. 2 m
兩根平行的傳爆線間距離不小於0 2米。 -
Except that, many problem can " t be solved, such as the conflict of ccd " s high resolving power and big vision field, how to control the automatic gathering of pcb " s image using master and slave computer parallel structure, how to inspect the defect of pcb such as width of circuit, distance of circuit, losing circuit and so on. the research aim at how to combine computer vision, precise machine, automatic control with image process, at how to resolve the contradiction between high resolving power of image gathering and wide vision field, at how to realize automatic mosaic of image, at how to realize precise orientation of two dimension worktable, at how to realize communication between master computer and slave computer, and at how to inspect the defect of line width, line distance and losing
除此以外，還有ccd高解析度和大視場之間的矛盾，上下位微機并行系統如何控制印刷電路板圖像自動採集，印刷電路板的線寬、線距和丟失線條等缺陷如何檢測等問題還懸而未決，本課題將就如何結合計算機視覺技術、精密機械技術、自動控制技術和圖像處理技術，如何解決圖像採集高解析度與大視場之間的矛盾，如何實現圖像的自動拼接，如何實現兩維工作臺的精確定位，如何實現上下位機的準確通訊，如何檢測線寬、線距缺陷和丟失線條等問題展開重點研究。
