面向扑翼飞行机器人的电子稳像算法设计

Design of an electronic image stabilization algorithm for flapping-wing flying robots

  • 摘要: 由于扑翼飞行机器人在飞行过程中机身存在周期性的俯仰和滚转运动,因此为了使成像效果更加清晰稳定,本文使用基于ORB和滑动均值滤波的电子稳像算法对航拍视频进行在线消抖处理。首先,基于扑翼飞行机器人航拍图像的抖动周期和机翼扑动周期相一致的特性,设计算法根据图像特征估计扑动周期。其次,设计与扑动周期相关联的运动滤波算法,针对不同飞行工况下的滤波参数自适应地进行动态调整。最后,为了验证算法的可行性和稳定性,本文将视觉成像装置搭载在扑翼飞行机器人上进行了飞行实验。实验结果表明,相比常用的电子稳像算法,本文所设计的算法在扑翼飞行机器人中具有更好的稳像效果。

     

    Abstract: Due to the periodic pitch and rolling movement of the flapping-wing flying robot during flight, this paper employs an electronic image stabilization algorithm based on ORB and sliding mean filtering to the video to enhance the clarity and stability of the real-time imaging effect. First, the algorithm is designed to estimate the flutter period based on the image characteristics, given that the jitter period of aerial images of a flapping-wing flying robot is consistent with the wing flutter period. Second, the motion filtering algorithm associated with the flutter period adjust the filtering parameters dynamically and adaptively for different flight conditions. To test the feasibility and stability of the strategy, the visual imaging device is attached to a flapping-wing flying robot for flight experiments. The experimental findings indicate that the algorithm proposed in this paper exhibits a superior stabilization effect in comparison to the commonly employed electronic stabilization algorithm.
