  • The contributions of this dissertation is listed below . aiming at existing defects of traditional beeline detection by hough transformation ( ht ) arithmetic , such as large storage space consuming , imprecise beeline detection effect and information loss of image feature pixels etc , we suggest two new beeline detection methods . ( 1 ) based on infinite symmetry exponential filter and its recursion arithmetic , new beeline detection methods can get exact direction of image edge pixels in advance , so it reduces highly the calculation quantity of the conventional ht , and improves the speed and the precision of beeline detection greatly
    本论文的主要研究成果列举如下:针对传统直线检测霍夫变换( houghtransform , ht )所存在的参数空间存储量大,直线检测不精确以及图像特征点信息丢失等缺点,提出两种新的直线段检测算法: ( 1 )提出一种基于无限对称指数滤波的ht直线段检测算法,在进行边缘检测的同时,提前精确定位边缘点的方向,减少了ht的运算量,提高了运算速度和检测精度,而且整体算法便于硬件的并行执行,使得实时处理成为可能。
  • The new algorithm starts from an initial estimate which is based on the hough transform , and a rectangular window is centered using the current line approximation , and a new line estimation is generated by making a total least squares fit through the pixels contained within the window . this is repeated until convergence is reached . lastly , we have suggested a new technique which may recover the motion and structure parameters of a moving object by using of 21 optical flow lines based on the optical flow fields of the feature line this thesis is the project supported by aeronautical foundation science ( no . 99f53065 ) and research center of measuring and testing technologies , and control engineering in nanchang institute of aeronautical technology ( no . 2001 - 15 )
    算法的思路是:首先,在小区域内运用霍夫变换确定直线的初始值;其次,以直线的初始值所对应的直线为中心线,建立一个矩形框;最后,利用矩形框内所包含的边缘点数据不断地迭代直至收敛,从而达到进一步修正直线的坐标参数;本文基于特征直线的光流场,即线流场,建立了一种利用21条光流线确定空间三维物体旋转运动参数、平移运动参数以及对应的空间直线坐标的线性算法。
