Visual Simulation Platform for Visible Light Reconnaissance Load of Unmanned Aerial Vehicle

针对无人机作战侦察时视觉系统参数对视频成像性能影响的仿真评估需求,设计并构建了一个无人机侦察载荷视景仿真平台。平台融合了视觉系统参数和飞行参数对实景视频进行仿真处理,为无人机侦察载荷系统评估和指标设计提供支撑,并为无人机侦察作战获得最佳效能时的视觉系统参数、飞行参数、飞行航迹设置提供指导。实验验证了平台5种仿真功能,根据设定的系统参数对无人机侦察视频进行视频剪裁缩放、视频亮度增强、视频滤波等仿真处理,能有效地实现可见光侦察载荷视景仿真。

In view of the simulation and evaluation requirement of the visual system parameters on the performance of video imaging during the operation and reconnaissance of unmanned aerial vehicle, a visual simulation platform for the reconnaissance load is designed and constructed. The collected video is processed according to the visual system parameters and the flight parameters, and the support for the evaluation and the index design of the unmanned aerial vehicle reconnaissance load system is provided, and the guidance is provided for the flight parameters and the flight track setting when the unmanned aerial vehicle reconnaissance and operation obtains the best performance. The experimental results verify 5 kinds of simulation functions of the simulation platform, which can carry out video clipping and scaling on the unmanned aerial vehicle reconnaissance video, and the video brightness enhancement and the video filtering process can effectively realize the visual simulation of the visible light reconnaissance load.
