  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. Both methods provide good performance, and the latter is better since it can give a better describing of the residual distribution of matches. in the study of camera self - calibration, firstly, based on discussion of using and the selecting of scene constraints, two new robust vanishing point estimation algorithms are presented. one is based on peransac, and the other is based on clustering

    在相機自定標技術的研究中，首先，在討論利用和選擇景物約束的基礎上，提出兩個新的消失點估計演算法:基於peransac的估計演算法和基於聚類分析的估計演算法，後者在估計精度上優於前者;其次，提出了綜合利用空間平行線約束和相機主點位置約束的線性迭代自定標方法，提高了相機自定標的魯棒性。
  3. To this problem a series of image rectification procedure which utilize geometric rectification theory in vehicle license recognition system are pointed out : we first locate vehicle license and execute the edge detection and binary conversion, then proceed calibration in which we use two calibration scheme looking for control point coordinate, one based on the hough transformation, the other based on image analysis method, and finally realize image correction in geometrical transform and bilinear gray interpolation method

    針對此問題本文給出了一套將幾何畸變校正技術應用到汽車牌照自動識別系統中的車牌圖像校正方法：首先提取牌照信息，並對圖像進行邊緣檢測和二值化的預處理；然後提出了基於hough變換控制點提取和基於圖像分析法的控制點提取的兩種實時標定方法；最後通過空間坐標變換和灰度插值完成圖像的校正。
  4. Camera self - calibration algorithm from matched - point sets on two orthogonal planes

    基於雙正交平面上匹配點對的攝像機自標定演算法
