The invention discloses an unmanned aerial vehicle video stream evidence obtaining system and method, and belongs to the technical field of parking charging, and the system comprises a parking apron, an unmanned aerial vehicle and a background server. According to the invention, multi-machine relay cruise is adopted, the unmanned aerial vehicle flies at a constant speed along an annular inspection path, and a power system only needs to maintain constant thrust to offset air resistance, so that the instantaneous power peak value is obviously reduced, the energy consumption is effectively optimized, and the service life of a battery is prolonged; and meanwhile, a natural redundant architecture is formed through multi-machine relay. When a certain unmanned aerial vehicle exits a task due to a fault or low electric quantity, the adjacent unmanned aerial vehicle can dynamically expand the inspection range to fill a blind area, and the robustness of the system is remarkably improved. And finally, when a plurality of unmanned aerial vehicles fly along the annular inspection path, setting a phase angle of 90 degrees between part of adjacent unmanned aerial vehicles, realizing multi-angle synchronous shooting of the same parking space through phase difference control, generating a three-dimensional evidence chain, solving the problem that traditional single-view-angle shooting is easy to block, and improving the reliability of evidence obtaining photos.

    本发明公开了一种无人机视频流取证系统及其方法,属于停车收费技术领域,包括停机坪、无人机和后台服务器。本发明采用多机接力巡航,无人机沿环形巡检路径保持匀速飞行,动力系统仅需维持恒定推力以抵消空气阻力,显著降低瞬时功率峰值,有效优化了能耗,以及延长电池寿命;同时,多机接力形成天然的冗余架构。当某一无人机因故障或电量不足退出任务时,相邻无人机可动态扩展巡检范围以填补盲区,显著提升系统鲁棒性。最后,多架无人机沿环形巡检路径飞行时,设置部分相邻无人机间隔90°的相位角,通过相位差控制实现同一车位的多角度同步拍摄,生成立体化证据链,解决传统单视角拍摄易受遮挡的问题,提高取证照片的可靠性。
