<P>PROBLEM TO BE SOLVED: To simply calibrate a zero-point off-set of a gyro. <P>SOLUTION: When a mobile terminal 10 moves from a first point to a second point where an error of a position or an angle is a specific amount, a server device 30 determines a difference between the position or the angle obtained at the second point and the specific amount by dead reckoning using output of a motion sensor 11. In addition, based on the difference obtained as the specification result, the server device 30 calculates a zero-point off-set which is a sensor value output by a gyro 11b when the moving body is static. <P>COPYRIGHT: (C)2013,JPO&INPIT |
