Abstract
An object tracking apparatus acquires detection information from a sensor mounted to a moving body, detects an object, and calculates a distance, a relative velocity, and an orientation thereof. For the initially detected object, the apparatus calculates aliased velocities of which aliasing from the relative velocity is assumed, and generates target candidates corresponding to the aliased velocities. For each target candidate, the apparatus estimates a current state of the target candidate from a past state thereof and observation information, and selects the target candidate estimated to be a true target from the target candidates for the same object. The apparatus calculates, as a reference velocity, an aliased velocity of the relative velocity that is equal to or greater than a velocity lower-limit value and is most negative or smallest in magnitude. The apparatus calculates the aliased velocities being the reference velocity aliased 0 to n times in a positive direction.
