SELF-POSITION MEASURING TERMINAL

摘要

An information processing apparatus including a positioning unit that determines a position of the information processing apparatus based on an external signal; a sensor unit that detects a change in position of the information processing apparatus; and a processing unit that measures, according to a change in position detected at the sensor unit, an amount of displacement of the information processing apparatus from a first time when the positioning unit starts to determine the position of the information processing apparatus to a second time when the positioning unit completes determining the position of the information processing apparatus; and identifies a position of the information processing apparatus at the first time by compensating the position of the information processing apparatus determined by the positioning unit at the second time with the amount of displacement of the information processing apparatus.

1. An information processing apparatus comprising:
positioning circuitry configured to determine a position of the information processing apparatus based on an external signal; a sensor unit configured to detect a change in position of the information processing apparatus, wherein the sensor unit comprises at least one of an electronic compass, an acceleration sensor and a gyro sensor; and processing circuitry configured to
determine whether the positioning circuitry has completed determining the position of the information processing apparatus based on the external signal;measure, according to a change in position detected at the sensor unit, an amount of displacement of the information processing apparatus from a first time when it is determined that the positioning circuitry has not yet completed determining the position of the information processing apparatus to a second time when it is determined that the positioning circuitry has completed determining the position of the information processing apparatus; andidentify a position of the information processing apparatus at the first time by compensating the position of the information processing apparatus determined by the positioning circuitry at the second time with the amount of displacement of the information processing apparatus.
