Abstract:
Disclosed is a positioning apparatus including: an autonomous navigation sensor which is held by a pedestrian and which outputs periodic oscillation and direction information; a step length data storage section which stores step length data; a movement distance calculating section which calculates movement distance; a traveling direction calculating section which calculates a traveling direction; and a movement direction calculating section which calculates a movement direction for each step, wherein the movement distance calculating section includes a taken step angle calculating section which calculates a taken step angle from the movement direction for each step with respect to the traveling direction; and the movement distance calculating section corrects a value of the step length data so that the step length is larger as the taken step angle becomes larger to calculate a movement distance for each step.
