METHOD FOR SYNTHETIC SENSOR DATA GENERATION

A method for generating synthetic sensor data using a scenario database is disclosed. The database includes a plurality of scenario samples, each comprising sensor data depicting a vehicle's surrounding environment over time. Each scenario sample has an associated scenario embedding in a multi-dimensional space and a corresponding transformation volume indicating possible transformed scenarios derived from that sample. The method includes obtaining a request specifying a query scenario, the query scenario having a query embedding in the multi-dimensional space. The method further includes identifying, within the scenario database, at least one scenario sample whose transformation volume contains the query embedding. In response to identifying such a scenario sample, the method generates synthetic sensor data for the query scenario by transforming the sensor data of the identified scenario sample so that the synthetic sensor data has an associated scenario embedding within a threshold distance of the query embedding.
