POSITION CALCULATION METHOD AND POSITION CALCULATION DEVICE |
| 摘要 |
A position calculation device includes an acceleration sensor and a gyro sensor to detect a movement of the user which is mounted on the body of the user, an arithmetic processing unit which executes setting a traveling direction axis by using a detection result of the sensor, using a change in a traveling direction of the user and correcting the traveling direction axis, and calculating a position based on the detection result of the sensor by using predetermined constraint condition based on the traveling direction axis. |

1. A position calculation method, comprising:
setting a traveling direction axis of a user by using a detection result of a sensor; estimating a change in a traveling direction of the user and correcting the traveling direction axis; and calculating a position by using predetermined constraint condition based on the traveling direction axis and by using the detection result of the sensor. |
