It is necessary for fully automatic relative orientation to realize precise and stable detection of tie points in stereo images. However, usual approaches such as template matching are not applicable to images of different conditions because parameters depend on features of images strongly. In this paper we proposed a series of techniques based on combination of probabilistic relaxation method and gradient method. By our approach, insensibility on setting parameters is achieved in individual methods and as a result total process is more robust. In addition, by examining detected points using relative orientation equation, it is possible to select points that satisfy required accuracy. The validity of proposed technique was verified by experiments using differently
