  • parameter : n. 1. 【數學】參數,變數;參詞;參項。2. 【物理學】參量;(結晶體的)標軸。3. 〈廢語〉【天文學】通徑。vt. -ize 使參數化。
  1. In the self - calibration scheme, the thesis emphasizes the accuracy of camera intrinsic and extrinsic parameters. we presents an accurate f method based on corresponding point adjustment. the method adjusts coresponding points according to the fixedness of projective transformed cross ratio, then calculates f matrix accurately through linear and non - linear methods. when computing intrinsic parameter, a matrix, we simplify the step, and stress on the two important parameters of a. the result will be getten through solving kruppa equation based on svd decomposition. in order to compute extrinsic parameters, we use linear method to get initial r and t, then apply non - linear method to accurate them

    提出了基於匹配點調整的f求精方法,先根據攝影交比不見性對手工選擇的匹配點進行調整,再用線性、非線性結合的方法求精f矩陣;在計算內部參數a中,進行了一定的簡化,把重心放在a中重要的兩個參數上,用svd分解法計算kruppa方程;在計算外部參數時,首先用線性法求解r 、 t ,然後再用非線性法迭代求精。
  2. 3. by using the dual concept between points and planes in 3d projective space, two classes of developable surfaces on c - b zier curve are constructed. the former is as a envelope of one - parameter plane family

    Zier曲線上可展曲面造型的方法:一個是作為單參數平面族包絡面的可展曲面構造,另一個是作為脊線的切線曲面的可展面構造。
  3. Finally, a method is put forward to construct the nurbs curves on sphere, which extends the de boor recursive algorithm in r3 to one on the sphere by replacing the geodesic distances for the lines and studies their many geometric properties analogous to those in euclidean spaces, such as the differential property, the local property, the parameter invariance under a projective transformation, and so on

    兩種方法均給出誤差估計,使逼近螺線可達到任何預先給定的精確階。最後,給出球面nurbs曲線生成演算法:用球面上測地線? ?劣大圓弧代替直線段,將歐氏空間r ~ 3中的deboor遞推演算法推廣到球面上構造麯線。
