Abstract: A computer-implemented method for analyzing a roundabout in an environment for a vehicle is disclosed. The method includes generating at least one initial feature map by applying a feature encoder module of a trained neural network to an input image. The input image depicts the roundabout. The method includes next applying a classificator module of the trained neural network to the initial feature map. An output of the classificator module represents a road region on the input image. The method includes next applying a radius estimation module of the trained neural network to the initial feature map. An output of the radius estimation module depends on an inner radius of the roundabout and an outer radius of the roundabout. The method includes finally determining an entry point and an exit point of the roundabout depending on the output of the classificator module and depending on the output of the radius estimation module.
