1. A computer-implemented method for analyzing a sensor data stream of a sensor device of a vehicle or a simulation characterizing a vehicle environment with respect to a presence of traffic scenarios which comprises:
ascertaining a similarity measure that indicates a degree of correspondence between a section of the sensor data stream and at least one template stored in a database of a computer by mapping the section of the sensor data stream onto the at least one template by means of dynamic time warping, wherein the at least one template characterizes a known traffic scenario, and wherein the similarity measure is formed by a distance between the section of the sensor data stream and the at least one template;
assigning the known traffic scenario to the section of the sensor data stream when the similarity measure satisfies a predefined similarity criterion; and
adapting the at least one template when the similarity measure simultaneously satisfies the predefined similarity criterion and a predefined adaptation criterion.
