PROBLEM TO BE SOLVED: To solve the problem that when an accuracy of predicting the position of a mobile object is deteriorated or occlusion occurs in a mobile object tracking device, it is likely to become difficult to track a mobile object. SOLUTION: A plurality of imaging parts 2 image a monitor space from different points of view. A tracking means 50 sets a hypothesis 406 expressing the combination of the predicted position of each mobile object at the current time with a single imaging part 2. In the hypothesis 406, different imaging parts 2 are set. The likelihood of each hypothesis 406 is calculated by a likelihood calculation means 504 by comparing the section corresponding to the predicted position of the monitor image of the imaging part 2 included in the hypothesis 406 with the image feature of the mobile object stored in the storage part 4. An object position determination means 506 determines the position of the mobile object at the current time based on the hypothesis 406 whose likelihood exceeds a predetermined value.
