Patent Images
1. A method for post-processing to synchronize audio data with vehicle data, the method comprising:
- generating proxy sound data based on time-series vehicle data;
determining an offset that maximizes cross-correlation between the proxy sound data and recorded audio data; and
shifting one or more of the time-series data and the recorded audio data relative to each other in time based on the offset to generate a synchronized set of time-series data and recorded audio data.

Abstract
A method for post-processing to synchronize audio data with vehicle data includes generating an artificial sound data based on time-series vehicle data. The method includes determining an offset that maximizes cross-correlation between the artificial sound data and recorded audio data. The method also includes shifting one or more of the time-series data and the recorded audio data relative to each other in time based on the offset. The shift may be used to generate or render a synchronized set of time-series data and recorded audio data.

9. A system comprising:
-
a proxy sound component configured to generate proxy sound data based on time-series vehicle data; an offset component configured to determine an offset that maximizes cross-correlation between the proxy sound data and recorded audio data; and a shift component configured to shift one or more of the vehicle time series data and the recorded audio data in time based on the offset to generate a synchronized set of time series data and audio data; wherein the time-series data comprises data produced by one or more vehicle sensors or control systems of the vehicle during a driving period and the recorded audio data comprises audio data recorded during the driving period. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. Computer readable storage media storing instructions that, when executed by one or more processors, cause the processors to:
-
generate proxy sound data based on time-series vehicle data produced by one or more vehicle sensors or control systems of the vehicle during a driving period; determine an offset that maximizes cross-correlation between the proxy sound data and recorded audio data, wherein the recorded audio data comprises audio from video data recorded during the driving period; render at least a portion of the video data; and during rendering a portion of the video data, determine and display a portion of the time-series data corresponding to the portion of the video data based on the offset. - View Dependent Claims (17, 18, 19, 20)
