<P>PROBLEM TO BE SOLVED: To extract three-dimensional information without photographing with the same sensor several times when extracting the three-dimensional information with a stereographic view and to easily automate the setting of parameters to be used for extraction. <P>SOLUTION: Parameter setting means allows an operator to manually input various observation parameters including a distance between a collection position A1 regarding a SAR sensor and an observation position 3, a distance between a collection position 13 regarding an optical sensor and the observation position 3 and a distance between the collection position A1 regarding the SAR sensor and a collection position B2 regarding the optical sensor and information corresponding to a plurality of characteristic points existing in a SAR image 4 from a collection position A and an optical sensor image from a collection position B. Image processing means 8 computes the triangle function of the plurality of characteristic points in two images 4, 5, based on information given by the parameter setting means 7, in extracting the three-dimensional information for the characteristic points in the two two-dimensional images 4, 5. <P>COPYRIGHT: (C)2004,JPO |
