- Abstract
- The advancement of drone services utilizing 5G technology has led to an increasing need for displaying high-resolution video and associated geometric information on web-based maps in real-time. Traditionally, Full HD video and KLV metadata have been used to display video and geometric data in applications or web browsers. However, there is a growing demand for services that stream and process 4K or higher resolution videos in real-time, especially for AI-driven analysis. To effectively handle 4K video and geometric data via web browsers, advanced real-time video processing technologies such as Media Source Extensions are required, along with precise timestamping and synchronization of KLV metadata, and 3D map mapping techniques. Mismatched synchronization between video and geometric information can lead to difficulties in making accurate decisions in real-time applications such as search and rescue for missing persons or detection operations. To effectively address this issue, this paper presents a synchronization technique capable of aligning 4K video and KLV metadata collected from drones with a precision of within 10 frames. By utilizing this synchronization method, we successfully demonstrated the synchronized display of 4K video streams from four drones along with their flight waypoints on a Cesium 3D map within a single web browser.
