Method And Apparatus For Indoor Mapping, Positioning, Or Navigation

A method for indoor positioning or navigation, the method comprising:

• obtaining a set of features which describe characteristics of a place in an indoor space;
• comparing the obtained set of features to addresses of respective indoor blocks into which the indoor space is spatially divided, wherein each indoor block is identified as being located at an address formed from a set of features which describe characteristics of the indoor block;
• and
• determining, based on the comparing, which of the indoor blocks corresponds to the place in the indoor space.

A method for indoor mapping, positioning, or navigation, the method comprising:

• collecting data that is obtained by one or more input devices with which a wireless device is equipped or that describes a trajectory with which the wireless device moves;
• extracting, from the collected data, a set of features which describes characteristics of a place at which the wireless device is located, at which the wireless device targets as a destination, or at which the wireless device targets to avoid;
• and
• performing, or assisting another node in performing, mapping, positioning, or navigation in the indoor space based on the extracted set of features.

An addressing node, comprising:

• processing circuitry;
• and
• memory containing instructions executable by the processing circuitry whereby the addressing node is configured to:
• determine multiple indoor blocks into which the indoor space is spatially divided;
• and
• for each of the indoor blocks, obtain a set of features which describe characteristics of the indoor block and identifying the indoor block as being located at an address formed from the set of features.

An indoor positioning or navigation node, comprising:

• processing circuitry;
• and
• memory containing instructions executable by the processing circuitry whereby the indoor positioning or navigation node is configured to:
• obtain a set of features which describe characteristics of a place in an indoor space;
• compare the obtained set of features to addresses of respective indoor blocks into which the indoor space is spatially divided, wherein each indoor block is identified as being located at an address formed from a set of features which describe characteristics of the indoor block;
• and
• determine, based on the comparing, which of the indoor blocks corresponds to the place in the indoor space.

An extracting node, comprising:

• processing circuitry;
• and
• memory containing instructions executable by the processing circuitry whereby the extracting node is configured to:
• collect data that is obtained by one or more input devices with which a wireless device is equipped or that describes a trajectory with which the wireless device moves;
• extract, from the collected data, a set of features which describes characteristics of a place at which the wireless device is located, at which the wireless device targets as a destination, or at which the wireless device targets to avoid;
• and
• perform, or assist another node in performing, mapping, positioning, or navigation in the indoor space based on the extracted set of features.
