    摘要: A position estimation system is provided, including at least one measurement unit, a plurality of evaluation units and a particle filter. The at least one measurement unit obtains a first information, wherein the first information at least includes a motion information and a corresponding noise model of a traced object. Each of the evaluation units has a corresponding evaluation model, wherein each evaluation model generates a corresponding unit displacement estimation according to the first information. The particle filter samples and generates a plurality of displacement estimations according to the unit displacement estimations and the corresponding noise models respectively.
