Document Type and Number:
Japanese Patent JP4046476
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an apparatus and a method for calculating a navigation capable of being applied to accurate imaging of all sensors at a high speed. SOLUTION: The apparatus for calculating the navigation comprises an observing point corresponding position calculator 22 inputting image data 19 of an imaging unit carried at a space navigator, position information 6 of the navigator, attitude information 12 and a sight line direction of the imaging unit to calculate positions of N pieces of observing positions in the case including offset errors, a deviating amount measuring unit 23 for measuring a deviating amount of a position of the observing point actually measured on the globe from the observing point calculated by the calculator 22, an error amount calculator 26 for calculating attitude and position offset errors by solving the offset error amounts of position 3 components of the navigator and attitude 3 components of the measured deviation amounts via simultaneous equations by expressing the offset error amounts in a linear sum of the deviating amounts, and attitude and position sensitivity calculating means 24, 25 for calculating sensitivities to become coefficients of respective items of the linear sum.
