PROBLEM TO BE SOLVED: To provide a multi-target tracking device can switch algorithm according to the degree of difficulty of tracking. SOLUTION: This device includes: a MFA tracking processing part 4 generating the correlation solution with MFA processing while taking multi-dimensional correlation using the observation values over a plurality of flames from a sensor 1 when satisfying the first condition for carrying out the MHT tracking processing at the previous observation time and the second condition for determining that the tracking at the previous observation time is difficult; a MHT tracking processing part 2 generating new track while taking two-dimensional correlation between the latest observation value from the sensor 1 and the existing tracking track and generating a plurality of assumptions when either of the first and the second conditions is not satisfied; a MHT assumption monitoring part 3 determining whether the tracking is difficult or not from the situation of the generated assumption during carrying out the MHT tracking processing; and a MHT assumption setting part 5 replacing the correlation solution generated by the MFA tracking processing part 4 as an assumption of the MHT tracking processing part 2.
