26. The non-statutory computer-readable storage medium implementing a mobile body track identification method according to claim 24 further comprising: storing the most-probable hypothesis and relevant hypotheses; determining whether or not variations occur in identifications detected in the predetermined time in the past; generating track-coupling candidates so as to generate hypotheses when it is determined that variations occur in identifications; selecting individual hypotheses from among the generated hypotheses when it is determined that variations occur in identifications, while selecting individual hypotheses from among the stored hypotheses when it is determined that no variations occur in identifications; and upon estimating the most-probable hypothesis among the generated hypotheses when it is determined that variations occur in identifications, storing the most-probable hypothesis together with all the other generated 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.
