1. A method of estimating a location of a driving vehicle, the method comprising:
obtaining, by an information providing vehicle at a plurality of points of time, relative location information of the driving vehicle represented in a local coordinate system of the information providing vehicle by processing surrounding images captured by the information providing vehicle;
converting the relative location information into absolute location information represented in an absolute coordinate system;
extracting property information for the driving vehicle by processing the surrounding image, the property information indicating a property of the driving vehicle that enables identification of the driving vehicle;
generating identification information that includes probability that the driving vehicle has the property information, the probability determined by counting a number of times that the property information is extracted from the surrounding images; and
transmitting the absolute location information of the driving vehicle and the identification information to a vehicle location estimating apparatus.
