Abstract

A method for processing raw data recorded from the real world with the aid of a sensor into test data for stimulating a control unit, including: providing recorded raw data from the real world; ascertaining real objects detected by the sensor from the raw data, and generating route data sets, which each describe a scene including images of these real objects at consecutive points in time. providing a library of synthetic objects; assigning synthetic objects to detected images of the real objects, replacing the detected images with synthetic objects; supplementing temporally consecutive route data sets with supplementary data sets before the first route data set; and generating test data by converting the route data sets supplemented by the supplementary data sets into raw data that would have been recorded in the real world by the sensor during the introductory period and the recording period.
