Abstract:
1. A positioning device comprising: a movement measuring unit that measures relative position variation; a positioning unit that is capable of measuring positional information; a control unit that performs control to: a position calculating unit that calculates positional information of each position on a travel route by cumulating information of position variation measured by the movement measuring unit with the positional information of the specified position, wherein the control unit provides preliminary reference positional information as positional information of the specified position to the position calculating unit, calculates positional information of each position on a travel route by the position calculating unit, and when the position determination spot is determined, obtains the positional information of the specified position by adding a difference between positional information of the position determination spot calculated based on the preliminary reference positional information calculated by the position calculating unit and positional information of the position determination spot measured by the positioning unit to the preliminary reference positional information.
