Design and Implementation of Battlefield Situation Visualization System Based on OSG

In view of the increasing multidimensional, detailed and dynamic nature of modern battlefield situation, the traditional two-dimensional (2D) battlefield situation visualization can no longer satisfy the needs of battlefield command and decision-making. Based on the in-depth study of OpenSceneGraph (OSG) and Qt. This paper designs and implements a three-dimensional (3D) visualization system of battlefield situation. This system combined with the radar system, uses User Datagram Protocol (UDP) protocol for real-time data communication. It is designed and implemented from four parts: resource management database, 3D visualization platform, radar system and interactive function realization. And the interactive function, such as radar beam dynamic scanning display, battlefield situation information display and playback, and real-time data communication, etc, are mainly designed in this system. The visualization results shows that the 3D visualization system has good real-time performance, comprehensive functions and strong sense of immersion. It has reference and guiding significance for the research and development of various application systems of 3D situation.
