The invention discloses an unmanned aerial vehicle laser charging tracking system using improved YOLOv8. Firstly, an airborne GPS module transmits positioning information to a ground end so as to realize primary positioning; thirdly, capturing an image of the unmanned aerial vehicle by a camera, performing reasoning by using an improved YOLOv8 model through the Raspberry Pi, and obtaining accurate position information of the unmanned aerial vehicle; the Raspberry Pi adopts unscented Kalman filtering to be combined with a PID control strategy to control a ground holder to be aligned with the unmanned aerial vehicle and activate a laser emission module to track a target in real time; the photovoltaic cell array receives laser and converts the laser into electric energy, and it is ensured that the unmanned aerial vehicle cell module receives the optimal electric energy through the maximum power tracking module; meanwhile, a photosensitive sensor monitors the illumination intensity in each direction, and assists an unmanned aerial vehicle MCU to control an airborne tracking holder to ensure that laser is continuously aligned with the center of the battery array; according to the method, the tracking difficulty caused by the scale change of the unmanned aerial vehicle image is solved, the detection robustness and accuracy in a complex environment are enhanced, and the charging efficiency is remarkably improved.

    本发明介绍了一种利用改进YOLOv8的无人机激光充电跟踪系统。首先,机载GPS模块向地面端传递定位信息以实现初级定位;接着,摄像头捕获无人机图像,由树莓派使用改进的YOLOv8模型进行推理,获取无人机精确位置信息;树莓派采用无迹卡尔曼滤波结合PID控制策略控制地面云台对准无人机并激活激光发射模块,实时跟踪目标;光伏电池阵列接受激光转化为电能,通过最大功率跟踪模块确保无人机电池模块接收到最优化的电能;同时,光敏传感器监测各方向光照强度,协助无人机MCU控制机载追踪云台确保激光持续对准电池阵列中心;本发明的提出解决了无人机图像尺度变化导致的跟踪困难,增强了在复杂环境下的检测鲁棒性与准确性,并显著提高了充电效率。
