Method and system for localizing spatially separated wireless transmitters
First Claim
1. A method of localizing of wireless transmitters, the method comprising:
- retrieving, by a localization device, one or more Received Signal Strength Indicator (RSSI) values measured by one or more sensors, corresponding to a plurality of wireless transmitters distributed in a region in which the one or more sensors are located;
generating, by the localization device, a plurality of clusters based on the retrieved one or more RSSI values, wherein the generation of the plurality of clusters is based on a K-means clustering algorithm;
generating, by the localization device, a binary image based on the generated plurality of clusters, wherein the binary image comprises one or more white regions and one or more black regions; and
localizing, by the localization device, a position of each of the plurality of wireless transmitters, based on a determination of contours of the one or more white regions present in the binary image, wherein the one or more white regions in the binary image are indicative of a region in which one of the plurality of wireless transmitters is present.

Abstract
A technique is provided for localizing a plurality of wireless transmitters. The technique includes retrieving Received Signal Strength Indicator (RSSI) values measured by one or more sensors, corresponding to the plurality of wireless transmitters distributed in a region in which the sensors are located. The technique further comprises generating, a plurality of clusters based on the retrieved RSSI values. The technique further comprises generating a binary image based on the generated clusters. The binary image comprises one or more white regions and one or more black regions. The technique further comprises localizing position of each of the plurality of wireless transmitters, based on a determination of contours of the one or more white regions present in the binary image.
