Abstract

Claims (31)

1. A method for validating a software component for highly automated driving, comprising:

reading with a data processing system unprocessed video data which depict at least one driving situation recorded from a vehicle perspective by a recording vehicle, the data processing system being outside of the recording vehicle;

processing the unprocessed video data into preprocessed video data using a vehicle processor connected to the data processing system for video preprocessing, wherein the vehicle processor is arranged on an adapter board, the adapter board being outside of the recording vehicle and connected to the data processing system via at least one interface of the data processing system, wherein the vehicle processor is configured to be installed within a vehicle;

using, with the data processing system, the preprocessed video data as input variables for the software component; and

validating the software component with the data processing system by comparing output variables of the software component associated with a reaction of the software component to the recorded at least one driving situation with an expected reaction.

2. The method according to claim 1 , the processing further comprising:

calculating an optical flow of the unprocessed video data using the vehicle processor; and

embedding the optical flow in the preprocessed video data.

3. The method according to claim 1 , the processing further comprising:

calculating depth information from the video data using the vehicle processor; and

embedding the depth information in the preprocessed video data.

4. The method according to claim 1 , the processing further comprising:

rectifying, using the vehicle processor, the unprocessed video data.

5. The method according to claim 1 , further comprising:

reading progress information from the software component;

generating control signals using the progress information; and

providing at least one of (i) the unprocessed video data or (ii) the preprocessed video data to the vehicle processor step-by-step in response to the control signals.

6. The method according to claim 1 , further comprising:

transferring the unprocessed video data in bulk to the adapter board.

7. The method according to claim 1 , wherein the method is performed by executing computer program instructions stored on a non-transitory machine-readable storage medium.

8. The method according to claim 1 , wherein the at least one interface of the data processing system includes at least one of a PCIe interface or an Ethernet interface.

9. A validation system for validating a software component for highly automated driving, the validation system comprising:

a storage device configured to store unprocessed video data which depict at least one driving situation recorded from a vehicle perspective by a recording vehicle;

a data processing system that is arranged outside of the recording vehicle; and

an adapter board that is arranged outside of the recording vehicle, the adapter board being connected to the data processing system via at least one interface of the data processing system, a vehicle processor being arranged on the adapter board, the vehicle processor being configured to be installed within a vehicle,

wherein the data processing system is configured to:

read the unprocessed video data from the storage device;

process the unprocessed video data into preprocessed video data using the vehicle processor that is connected via the adapter board;

use the preprocessed video data as input variables for the software component; and

validate the software component by comparing output variables of the software component associated with a reaction of the software component to the recorded at least one driving situation with an expected reaction.

10. The method according to claim 9 , wherein the data processing system executes computer program instructions stored on a non-transitory machine-readable storage medium.
