Abstract

A method and a device for increasing the accuracy of localization. The method includes the following steps: a) detecting a selected object in an environment, using a camera of a first vehicle; b) estimating a first position of the selected object, wherein a first program uses first location coordinates of the first vehicle and a first distance estimate to the selected object; c) transferring an attribute of the selected object, the first location coordinates and the first distance estimate to a server; d) carrying out the steps a) to c) for a second vehicle; e) calculating a third position of the selected object by the server, wherein a third program performs an averaging of the plurality of location coordinates and distance estimates; f) using the third position of the selected object as a reference position for increasing the accuracy of a localization of a third vehicle.

Claims (13)

1. A device for increasing the accuracy of localization in a vehicle, which comprises a computation and control device, which is configured to perform operations comprising:

a) detecting a selected object in an environment, using a camera of a first vehicle;

b) estimating a first position of the selected object, by means of a first program for localization, in the first vehicle,

wherein the first program uses first location coordinates of the first vehicle and a first distance estimate to the selected object;

c) transferring an attribute of the selected object, the first location coordinates, and the first distance estimate to a server;

d) carrying out the steps a) to c) for the selected object, to estimate a second position of the selected object, using a camera of a second vehicle, by means of a second program for localization, using second location coordinates and a second distance estimate;

e) replacement, on the server, of the first location coordinates and the second location coordinates, by means of a fourth program, using corrected first location coordinates and corrected second location coordinates,

wherein the fourth program uses raw Global Positioning System data to determine more accurate data for the corrected first location coordinates and the corrected second location coordinates;

f) calculating a third position of the selected object by the server, by means of a third program, using the corrected first location coordinates and the corrected second location coordinates,

wherein the third program performs an averaging of the corrected first location coordinates and the corrected second location coordinates; and

g) using the third position of the selected object as a reference position for increasing the accuracy of a localization of a third vehicle.

2. The device as claimed in claim 1 , wherein the selected object is a static landmark or a traffic sign.

3. The device as claimed in claim 2 , wherein the position is specified in WGS 94 coordinates.
