Problems solved by technology

If the motor vehicle changes its direction, for example during a turning process, it is difficult to detect traffic signs not only by the driver but also by the recognition system
As a result, the driver cannot be oriented with respect to the valid traffic regulations, so that even with the use of the recognition system there is still the risk of the driver driving the motor vehicle in violation of the traffic regulations.

Embodiment Construction

[0025] figure 1 A recognition system 100 for traffic signs on a motor vehicle 105 is shown. The system 100 includes an identification system 110 , a navigation system 115 and a selection device 120 . Recognition system 110 is provided to recognize traffic signs in a camera image of a camera on motor vehicle 105 . A front camera 125 , a left camera 130 and a right camera 135 are provided on the motor vehicle 105 . Cameras 125 to 135 can also be used on motor vehicle 105 for further purposes, for example to support the driver when parking or leaving a parking lot or to provide a round image for the driver. The indication of the traffic signs recognized by the recognition system 110 can be output by means of an output device 140 , wherein the output device 140 can provide audible, visual or tactile signals. The output device 140 can likewise be used together with other systems or auxiliary devices on the motor vehicle 105 ; in another embodiment, the output device 140 is assig...

Abstract

A method for supporting a driver in a motor vehicle comprises the steps of determining an upcoming change of direction of the motor vehicle on the basis of information from a navigation system, selecting a camera image of a front camera or a side camera depending on the determined change of direction, Traffic signs in the surroundings of the motor vehicle are determined on the basis of the selected camera images.

Description

technical field [0001] The invention relates to traffic sign recognition on motor vehicles. In particular, the invention relates to traffic sign recognition by means of a plurality of different cameras. Background technique [0002] A traffic sign recognition device on a motor vehicle captures images from a forward-facing camera and attempts to recognize traffic signs in the images it captures. The traffic signs can include, for example, traffic lights (signal lights) or street signs. In the case of traffic lights, the current state can also be analyzed, ie it can be determined which signal is currently being given by the traffic light. The sampled information is typically displayed visually to the driver of the motor vehicle. A further possibility of this information is that, for example, a tactile or audible warning can be implemented if the motor vehicle violates regulations such as the valid speed limit, which is derived from the detected traffic signs. [0003] The ...
