    The authors proposed recently a matching method of aerial photographs based on a so-called coarse-to-fine method. But it is not provided with a routine for processing images containing occluding areas. They attempt in this pafer to incorporate a routine for finding and processing occlusions. The discussion proceeds along the following outline.
    (1) In the authors' method, measured x-parallaxes are low-pass-filtered fo filter the higher frequency noises included in them. But this operation forcibly reproduces the occluding terrain to be of smooth shape.
    (2) The low-pass filter is substituted for the median filter which is characterized by preserving abrupt changes of x-parallaxes across the occlusions. The procedure for finding occlusions is carried out by use of this filter.
    (3) It is demonstrated that the procedure (2) is valid in principle. But because matching stability of the authors' current method is still insufficient, a few wanderings occur even at other points than occlusions and they disturbe the correct matching.

  • Outlook on Methods of Stereo Matching by Computer and Auto-correlators for Photogrammetry

    This paper presents an outlook on the methods of stereo matching by computer which have been developed to date. The methods can be classified into
    (1) Area correlation, (2) Matching of features and (3) Matching of segmented sub-areas.
    In photogrammetry the area correlation method has been exclusively employed for stereo plotting. The other two methods have been developed in the field of ‘computer vision’. They are forecasted to be adaptable also in the photogrammetric field, especially for plotting large scale photographs, where occlusions occur frequently and objects with little textures show up.
    Further the structures of some types of auto-correlators and their matching precision are briefly reviewed.
