Pedestrian observation system, recording medium, and estimation of direction of travel |
摘要 |
<p>A pedestrian observation system includes a circuitry acquires an acceleration in accordance with a uniquely defined terminal coordinate system accompanying a pedestrian; obtains a power of an acceleration in a horizontal plane containing mutually perpendicular first and second directions based on acceleration components in the first and second directions, thereby acquiring an observation time of a maximum value of the power and acceleration components in the first and second directions at that time to acquire horizontal peak information; acquires times of observation of maximum and minimum values of a vertical acceleration component to acquire vertical peak information; chooses information on the maximum value of the power from the horizontal peak information based on the vertical peak information to acquire peak information for estimation; and acquires traveling direction information indicating a direction of travel of a pedestrian based on the peak information for estimation.</p> |
