Abstract:
A method for locating an object using cluster-type magnetic field is disclosed. The method implemented on an electronic apparatus, comprises: obtaining a wireless signal and a magnetic field signal; performing a first locating for an object according to the wireless signal; and performing a second locating for the object according to the magnetic field signal in the range of the first locating. In addition, an apparatus and a system for locating an object using cluster-type magnetic field are also disclosed. Accordingly, the present invention performs a first rough locating for an object by a wireless signal and then a precise locating for the object in the range of the first locating, thus reducing the amount of calculation, lowering computational complexity and improving accuracy of locating.

Claim (Index 5):
The method of  claim 2 , wherein a state updating equation for performing the position updating of the predicted second position is: p \ue8a0 ( x t \ue85c z 1 : t ) = p \ue8a0 ( z t \ue85c x t ) \ue89e p \ue8a0 ( x t \ue85c z 1 : t - 1 ) \u222b p \ue8a0 ( z t \ue85c x t ) \ue89e p \ue89e ( x t \ue85c z 1 : t - 1 ) \ue89e dx t , where p(x t |z 1:t ) is a posterior probability after updating a measured value at time t, p(z t |x t ) is an importance density function, p(x t |z 1: t-1 ) is a posterior probability density distribution of the object at time t.
