    利用基於線性插值的canny運算元提取邊緣,通過本課題提出的圓周弦長灰度檢測法得到指針的指示方向,進而依據指針相對于基準的圓心角和關聯關系正確讀數。數據庫信息管理系統實現對用戶用水信息的管理,主要功能分三大模塊:一
  2. Corner detection based on accumulative chord length is invariant to rotation transformations, while the implicitly refining strategy of digital curves can improve computational precision and enhance the reliability of corner detection significantly

    摘要提出基於曲線累加弦長來檢測角點,可以使得檢測結果具有旋轉不變性,隱式精化曲線策略可以顯著改善角點檢測演算法的計算精度,從而增強角點檢測結果的可靠性。
  3. Secondly, the problem of the curve - surface mutual transforming and smooth - finishing have been analyzed farther. for the surface intersecting problem : owing to the introduction of the boundary points, as long as the intersecting points on a certain line, the full intersecting line can be gained. the intersecting line either intersects at the boundary of the triangle surface or forms the loop ; during the course of tracking, the selecting of the pace is restricted by the curvature, the number of the gained intersecting points are not in proportion as the chord - length ; the intersecting points not only record the coordinate and store the parameter

    對兩曲面求交問題,當曲面細化足夠小時,曲面求交可近似看成曲面與平面相交問題,引進了邊界點的概念,因此只要知道交線上的任意點,就可以將跨越許多曲面片的整條交線計算出來,所求出的交線或者跨越曲面的邊界,或者形成交線環;從初始點出發跟蹤求解整條交線的過程中,步長的選擇採用了通過曲面片曲率來約束的方法,用該方法求出的交點在不同曲面片上的分佈數目不與弦長成正比;該求交方法包含了各曲面片的邊界線與交線的交點的求解,可獲得邊界交點的坐標值及其參數值。
  4.
