METHOD FOR EXECUTION BY A SENSOR SYSTEM FOR A TRAFFIC INFRASTRUCTURE DEVICE, AND SENSOR SYSTEM
The invention relates to a method for execution by a sensor system for a traffic infrastructure device, by means of which method a transformation rule for a coordinate transformation of radar data recorded by means of a radar device and of video data recorded by means of a video camera is determined on the basis of an assignment of road users recorded by means of the video camera to road users recorded by means of the radar device. The invention further relates to a corresponding sensor system.
