<P>PROBLEM TO BE SOLVED: To highly accurately perform error correction even when observation errors of a sensor are different from each other in accordance with position/observation conditions of observation space. <P>SOLUTION: A sensor error calibration system includes: sensor control means 8 for calculating a position of observation space based on reference position information and controlling a sensor 3; observation error calculation means 10 for calculating observation error/error correction values based on the observation position information and reference position information of a reference target 1; an information storage unit 12 for storing observation conditions including flight route information/observation environment information based on the reference position information, the position of the observation space and the error correction values in relation to each other; observation error correction value optimization means 16 for extracting the error correction value from the information storage unit 12 based on observation conditions including the flight route information/observation environment information of an observation target and the position of the observations space based on the observation position information; and observation error correction means 17 for correcting the position of the observation target observed by the sensor 3 by using the extracted error correction value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
