METHOD FOR GENERATING AND USING A MAP

摘要

The invention pertains to a Method for using and generating a map, in particular an indoor map, allowing for localizing a position based on one or more detected wireless signals originating from one or more sources (SRC1, SRC2, SRC3, SRC4), whereby a source (SRC1, SRC2, SRC3, SRC4) is selected from the group comprising near field communication device, mobile telephone, W-LAN access point, Bluetooth access point, etc.. The method comprises a step of detecting (100) at certain positions (Rho1, P2, P3, P4); each of said certain positions corresponding to a position on the map, by a plurality of detectors (MD1, MD2, MD3, MD4) at substantially the same time at least one wireless signal originating from at least one of said one or more sources (SRC1, SRC2, SRC3, SRC4) with respect to its signal strength. The plurality of detectors (MD1, MD2, MD3, MD4) are arranged such that they reflect different positions of a corresponding user device (UD1, UD2) and its physical characteristics such as attenuation or scattering when worn by a user at the human body, thereby allowing for providing detected signal strengths with respect to different orientations. The method comprises also as step of storing (200) said signal strengths of each detected wireless signal originating from said one of said one or more sources (SRC1, SRC2, SRC3, SRC4) with respect to the plurality of detectors (MD1, MD2, MD3, MD4) and the certain position. Thereafter the method allows for provisioning (300) of said map. Afterwards a user device (UD1, UD2) may detect (400) at an unknown position a number of wireless signals and their signal strength, and the method allows for comparing (500) said wireless signals detected by said user device (UD1, UD2) with said stored signal strengths with respect to at least a best match in order to ensure that a certain position of the user device (UD1, UD2) with respect to a human body and its physical properties are correctly taken into account. The invention also pertains to an appropriate Measurement arrangement for generating a map, in particular an indoor map, as well as for a user device (UD1, UD2) for using a map.
