29. The non-transitory computer-readable storage medium implementing a mobile body track identification method according to claim 24 further comprising: calculating a track-coupling likelihood representing a likelihood of connecting tracks included in each of track-coupling candidates in track-coupling candidate/identification pairs ascribed to each of the selected hypotheses; and estimating the most-probable hypothesis based on identification likelihoods and track-coupling likelihoods of hypotheses.
24. The non-transitory computer-readable storage medium implementing a mobile body track identification method according to claim 23 further comprising: storing a probability map defining detection probabilities of identifications of mobile bodies in response to their positional coordinates in the tracking area in advance; specifying a position of a mobile body on tracks indicated by each track-coupling candidate at each identification detection time for each track-coupling candidate/identification pair ascribed to each of the selected hypotheses; reading a probability value of detecting the mobile body at the position from the probability map; calculating an identification likelihood based on the probability value; further integrating identification likelihoods for each track-coupling candidate/identification pair so as to calculate an identification likelihood regarding each of the selected hypotheses; and estimating the most-probable hypothesis based on identification likelihoods of hypotheses.
