Abstract
In accordance with an aspect of the present disclosure, there is provided an apparatus for estimating a location of a vehicle including, a communication unit configured to receive, from an information providing vehicle, identification information and location information on a driving vehicle in a vicinity of the information providing vehicle, a weighted value obtaining unit configured to obtain a weighted value representing accuracy of the location information based on the received identification information and a location estimating unit configured to estimate a location of the driving vehicle by applying the weighted value to the location information.
Claims8
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.
A non-transitory computer-readable storage medium including computer executable instructions, wherein the instructions, when executed by a processor, cause the processor to perform a transfer method, the method comprising:
- obtaining, by an information providing vehicle at a plurality of points of time, relative location information of a 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.
