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. The method involves extracting video frames from a video file and identifying a time interval associated with a marker in the video frames. It also involves identifying the corresponding time points of the video frames and the sound signals in the video file. Based on the time difference between these points, the method outputs a result associated with the time synchronization performance of the driving video recording system.
- The method extracts video frames from a video file.

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.
