Method to correlate an object with a localized tag

A data processing device comprising:

• a module that transmits a trigger signal, at a first frequency range, that propagates into a space to determine if one or more tags exist in the space within a detectable distance;
• and
• a processor that is communicatively coupled to the module and which:
• receives, by the module, at least one response signal from a tag antenna corresponding to a respective tag of one or more tags that exist in a space located within a detectable distance of the module, each tag antenna capable of producing a corresponding response signal in response to a trigger signal, the corresponding response signal having a unique tag identification (ID) of the respective tag modulated thereon;
• in response to receiving the corresponding response signal from the respective tag within the space, identifies a directional location of the respective tag relative to the module, wherein to identify the directional location the processor:
• determines, for the respective RFID tag and object, (i) a general horizontal position within the space along a horizontal axis relative to the user device (ii) a general vertical position within the space along a vertical axis relative to the user device;
• activates a camera device to focus on one or more focal points in an area in the directional location of the respective tag;
• estimates, based on a signal strength and the directional location of the corresponding response signal, a distance of the respective tag relative to the module;
• captures, by the camera device, an image of an object located within the area in the directional location of the respective tag;
• in response to capturing the image, correlates the (i) directional location, (ii) distance of the respective tag, and (iii) image of the object to generate corresponding position information that provides a more precise point location of the object that corresponds to the respective tag within the space;
• and
• outputs the corresponding position information of the object that corresponds to the respective tag.

A computer program product comprising:

• a computer readable storage device;
• and
• program code on the computer readable storage device that when executed within a processor associated with a user device, the program code enables the user device to provide a functionality of:
• receiving, by a user device, at least one response signal from a tag antenna corresponding to a tag of one or more tags that exist in a space located within a detectable distance of the user device, each tag antenna capable of producing a corresponding response signal in response to a trigger signal, the corresponding response signal having a unique tag identification (ID) of the respective tag modulated thereon;
• in response to receiving the corresponding response signal from the respective tag within the space, identifying, by a processor, a directional location of the respective tag relative to the user device, wherein the user devices identifying the directional location comprises determining, for the respective RFID tag and object, (i) a general horizontal position within the space along a horizontal axis relative to the user device;
• and (ii) a general vertical position within the space along a vertical axis relative to the user device;
• activating a camera device to focus on one or more focal points in an area in the directional location of the respective tag;
• estimating, based on a signal strength and the directional location of the corresponding response signal, a distance of the respective tag relative to the user device;
• capturing, by the camera device, an image of an object located within the area in the directional location of the respective tag;
• correlating the (i) directional location, (ii) distance of the respective tag, and (iii) image of the object to generate corresponding position information that provides a more precise point location of the object that corresponds to the respective tag within the space;
• and
• outputting the corresponding position information of the object that corresponds to the respective tag.
