A generalized video synchronization technology for serial communication data interface

The rapid development of Internet of Things (IoT) technology has made the interconnection of all things a reality. However, multi-source data fusion still faces challenges such as the diversity of different device interfaces, the non-unification of device clocks, and the high integration of video acquisition devices. The data synchronous acquisition of serial communication interface and image video is of great significance due to its wide application. Based on the digital signal detection of the serial communication data interface in this study, and in combination with the application of the OpenCV image processing control, the data synchronous acquisition of the serial communication interface and the USB camera is realized. The system is experimentally verified by using the radar velocimeter. The measured data synchronization accuracy is less than 1ms, providing a feasible technical means for multi-scenario applications.
