Patent attributes
An apparatus for providing location information includes a plurality of sensor units which are distributed throughout a confined area lacking a global positioning system (GPS) coverage and have respectively a plurality of FOVs that at least partially overlap with each other in an overlap area, each of the plurality of sensor units including a first sensor and a second sensor of a type that is different from a type of the first sensor; and a processor. The processor is configured to fuse sensing data provided by the first sensor and the second sensor that are respectively included in each of the plurality of sensor units, identify a location of an object existing in the overlap area based on the fused sensing data, and provide location information of the identified location to the object.
