METHOD AND APPARATUS FOR EVALUATING PERFORMANCE OF DRIVE VIDEO RECORD SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 17967480 titled 'METHOD AND APPARATUS FOR EVALUATING PERFORMANCE OF DRIVE VIDEO RECORD SYSTEM

Simplified Explanation

The abstract describes a method for evaluating the performance of a driving video recording system. Here are the key points:

  • The method involves extracting multiple video frames from a video file.
  • A time interval associated with a video frame that contains a marker is identified.
  • The first time point within the time interval corresponding to the video frame is identified.
  • The method also identifies a sound signal from the video file that corresponds to the video frame.
  • The second time point within the time interval associated with the sound signal is identified.
  • Based on the time difference between the first and second time points, a result is outputted to assess the time synchronization performance of the driving video recording system.

Potential applications of this technology:

  • Evaluating the performance of driving video recording systems used in vehicles.
  • Assessing the accuracy of time synchronization between video frames and corresponding sound signals.
  • Monitoring and improving the reliability of video recording systems in capturing events during driving.

Problems solved by this technology:

  • Ensures accurate time synchronization between video frames and sound signals in driving video recording systems.
  • Provides a method for evaluating the performance of such systems in terms of time synchronization.
  • Helps identify any discrepancies or delays in the recording system's synchronization.

Benefits of this technology:

  • Enables the identification and rectification of any issues with time synchronization in driving video recording systems.
  • Provides a quantitative measure of the system's time synchronization performance.
  • Allows for improved reliability and accuracy of recorded video footage during driving.


Original Abstract Submitted

A method for evaluating performance of a driving video recording system may include extracting, by a control device, a plurality of video frames from a video file, identifying, by the control device, a time interval associated with at least one video frame that comprises a marker among the plurality of video frames and identifying a first time point, of the time interval, corresponding to the at least one video frame, identifying, by the control device and from the video file, a sound signal corresponding to the at least one video frame to identify a second time point, of the time interval, associated with the sound signal corresponding to the at least one video frame, and outputting, by the control device and based on a time difference between the first time point and the second time point, a result associated with a time synchronization performance of the driving video recording system.
