Abstract
The present invention relates to a virtual radio map constructing method for Radio-positioning and a device using the same. An exemplary embodiment of the present invention provides a virtual radio map constructing method, including: converting first and second RSS values obtained from two access points adjacent to each of a plurality of access points into first and second RSS values of a linear unit; respectively dividing first and second distances between the access point and the two access points adjacent thereto in an exponential interval, and respectively dividing the first and second RSS values in the exponential interval; generating a plurality of virtual training points by using a plurality of points divided in the exponential interval, and respectively obtaining RSS values of the plurality of virtual training points; and respectively obtaining RSS values of reference points by using RSS values of at least one virtual training points.
