| Research Abstract |
(1) Satellite CCD line-scanner imagery with very high ground resolution will be avalable in a few years. Based an on affine transformation, we constructed orientation theory of the satelite imagery having very weak geometry and investigated its characteristics through many simulation models. As the results, the method proposed has been clarified to have a very high geometric accuracy. Also, the investigation of the accuracy difference between cross-truck images and three-line sensor images has revealed that the former has higher geometric potential.
(2) A free network theory applicable for affine line-scanner imagery was derived and tested with many simulated examples. From the results it has been known that the accuracy improvements are about 10 percents.
(3) High precision stereo matching techniques are required for real-time production of large-scale topographic maps from the high resolution satellite imagery. We developed a method of stereo matching using simulated annealing. Tests with many practical examples showed that this method has a fairly good accuracy and also be applied for the interpolation of image occlusions.
