Abstract
A method, apparatus, computer readable storage medium and system are disclosed for generating a radio map for indoor navigation and/or floor detection. The method includes obtaining one or more first fingerprints, which stem from one or more radio nodes comprised by an infrastructure of a venue. The one or more radio nodes are surrounding the first apparatus so that the first apparatus is located within each respective coverage area of the one or more radio nodes. The method also includes generating a radio map based at least partially on the one or more first fingerprints; and outputting the generated radio map.
Claims17
A first apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the first apparatus to at least perform:
- obtaining one or more first fingerprints, which stem from one or more radio nodes comprised by an infrastructure of a venue, and wherein the one or more radio nodes are surrounding the first apparatus so that the first apparatus is located within each respective coverage area of the one or more radio nodes, wherein the one or more first fingerprints are obtained by either (a) receiving one or more respective radio measurements, wherein one or more respective radio measurements are gathered by one or more radio nodes, and generating the one or more first fingerprints based at least partially on the obtained one or more respective radio measurements and on one or more pieces of position information, wherein the one or more pieces of position information are indicative of the respective location of the one or more radio nodes from which the one or more respective radio measurements were obtained or (b) receiving the one or more first fingerprints;
- generating a radio map based at least partially on the one or more first fingerprints;
- and
- outputting the generated radio map.
A second apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least perform:
- gathering one or more respective radio measurements in a venue, wherein one or more respective signals are sent by one or more respective radio nodes surrounding the second apparatus, wherein each respective radio measurement of the one or more respective radio measurements is indicative of at least one respective piece of identifier information which is associated with the one or more respective radio nodes surrounding the second apparatus, and wherein each of the one or more radio nodes surrounding the respective radio node is uniquely identifiable based at least partially on the at least one respective piece of identifier information;
- obtaining a piece of position information, wherein the piece of position information is indicative of the location of the second apparatus in the venue;
- and
- broadcasting the one or more respective radio measurements and position information together to form a fingerprint, wherein the one or more respective fingerprints are configured to be communicated and recorded amongst apparatuses.
A first method, performed by at least one first apparatus, comprising:
- obtaining one or more first fingerprints, which stem from one or more radio nodes comprised by an infrastructure of a venue, and wherein the one or more radio nodes are surrounding the first apparatus so that the first apparatus is located within each respective coverage area of the one or more radio nodes, wherein the one or more first fingerprints are obtained by either (a) receiving one or more respective radio measurements, wherein one or more respective radio measurements are gathered by one or more radio nodes, and generating the one or more first fingerprints based at least partially on the obtained one or more respective radio measurements and on one or more pieces of position information, wherein the one or more pieces of position information are indicative of the respective location of the one or more radio nodes from which the one or more respective radio measurements were obtained or (b) receiving the one or more first fingerprints;
- generating a radio map based at least partially on the one or more first fingerprints;
- and
- outputting the generated radio map.
