Method for classifying a traffic sign, or road sign, in an environment region of a motor vehicle, computational apparatus, driver assistance system and motor vehicle

Abstract

The invention relates to a method for classifying a traffic sign () in an environment region () of a motor vehicle () as a traffic sign sticker () located on an industrial or commercial vehicle () or as a stationary traffic sign (), wherein in the method at least one first image () of the environment region (), captured by a camera () of the motor vehicle (), is received and the traffic sign () is recognized in the at least one first image (), wherein a geometric dimension (D', D′) of the traffic sign () in the first image () is determined on the basis of said first image (), a first reference dimension (Dmin, Dmax), which is characteristic of a stationary traffic sign (), is prescribed for the captured traffic sign (), a first position (Pmin, Pmax) of the traffic sign () in the environment region () is estimated based on the geometric dimension (D′, D′) of the traffic sign () in the first image () and on the basis of the first reference dimension (Dmin, Dmax), and the traffic sign () is classified as the traffic sign sticker () or as the stationary traffic sign () based on the estimated first position (Pmin, Pmax). The invention additionally relates to a computational apparatus (), a driver assistance system () and a motor vehicle ().
