摘要: Disclosed is a method for real-time object locating and mapping, including: 1) performing real-time locating for a moving object in the range of movement; 2) updating a geomagnetic field map in the range of movement of the object in real time according to the locating of the moving object; 3) locating the next position of the moving object according to the updated geomagnetic field map; and repeating steps 2) and 3) until the object stops moving. A device for real-time object locating and mapping is also disclosed. The present application can solve the problem of real-time object locating and accurate geomagnetic field mapping without an indoor priori magnetic field map.

摘要: A method and system for locating an object are disclosed. The method comprises generating a plurality of sampling points in an activity area map for an object; obtaining a conditional probability density of the object's locating at the plurality of sampling points according to an initial electromagnetic field intensity of the plurality of sampling points and a current electromagnetic field intensity of the object to be located; conducting resampling and updating for the sampling points according to the conditional probability density; and determining a position of the object to be located based on coordinate values of sampling points after the updating. The present invention can improve the accuracy of the locating or tracking on an indoor object.
