In response to the demand for three-dimensional visualization of multiple unmanned aerial vehicles (UAV), aimed at addressing issues such as lack of intuitive information representation, insufficient display of model details, and low efficiency in flight path planning within existing visualization software, we conducted research on a three-dimensional visual scene system for multiple aircraft based on OSGEarth. This system aims to showcase the real-time flight situation. Leveraging the OSGEarth three-dimensional rendering engine, we load and display high-precision three-dimensional digital maps. With three-dimensional scene construction and management as the core, the system achieves real-time dynamic display of multiple aircraft models and rapid switching of perspectives. By employing flight route design rules, we designed a workflow for automatically generating and confirming mission routes. Validation through multiple flight experiments indicates that the three-dimensional visual scene system provides strong visualization capabilities, intuitively displaying flight dynamics during flight experiments, efficiently assisting in the completion of flight missions, and enhancing flight safety.
