Method and device for traffic sign recognition

A method for recognizing a traffic sign for an autonomously driving vehicle, the method comprising:

• reading in a recognition signal representing a traffic sign in road traffic that is recognized using an optical sensor of the vehicle;
• providing an information signal and a position signal at an interface to a server based on the recognition signal, the information signal representing a piece of information concerning the traffic sign, and the position signal representing an instantaneous position of the vehicle;
• and
• reading in a confirmation signal that represents a match of the recognized traffic sign with a sign that is noted on a map at the instantaneous position of the vehicle, via the interface to the server,
• wherein the reading in includes reading in an uncertainty signal, wherein the uncertainty signal represents an uncertainty in recognizing the traffic sign in road traffic that is recognized using the optical sensor of the vehicle, and
• wherein the uncertainty in recognizing the traffic sign results because the traffic sign is at least partially concealed because of an obstruction or not fully visible due to weather conditions.
