DATA RECORDING FOR ADAS TESTING AND VALIDATION

A system (1) for assessing progress of a data-recording campaign performed to collect sensor data (S1) recorded by a sensor data recorder (30) mounted on a vehicle (5), the system comprising a metadata-generating apparatus (40) arranged to process data (S1, S2) acquired by a sensor module (20) to generate metadata (M) for the sensor data, the metadata comprising classifications of an attribute of a driving environment the vehicle was in during the acquisition of the sensor data into respective classes of a predefined set of classes of the attribute, and transmit the metadata to a remote metadata-processing apparatus (60), which is arranged to determine whether the metadata comprises at least a predetermined number of classifications in a predefined class of the set of predefined classes and, based on the determination, generate an indicator (T) for use in the data-recording campaign.
