Remote Driving Streaming Automatic Latency Testing Method and System Based on Digital Clock

This invention identifies digital clocks in both streamed and pulled videos using screen regions and screenshots. Image recognition is used to calculate time differences between the clocks, followed by simple outlier filtering and basic statistical analysis to measure latency. In later stages, OpenCV was integrated to automatically detect clock regions and improve image preprocessing. This enhanced the accuracy and efficiency of the system, leading to better overall performance in latency testing.
