Visual Positioning Method and System for Rotor Flying Robot

  • 摘要: 为实现旋翼飞行机器人在室内环境中的精确定位及控制,设计了基于单目视觉的机载视觉定位方法.该方法通过矩特征提取、图形分类来识别地面标记图形,进而利用 EPnP方法解算摄像机坐标.为验证机载视觉定位方法的有效性,利用 Kinect 传感器搭建了旋翼飞行器外部定位系统,设计了针对旋翼飞行器目标的视觉跟踪算法,定位精度达 2 mm.实验结果表明,机载视觉定位方法能够很好地进行飞行器定位.

     

    Abstract: To achieve exact positioning and control of the rotor flying robot in indoor environments, an onboard visual positioning (OVP) method based on monocular vision is designed. It can recognize landmark images by moment feature extraction and image classification, and calculate camera coordinates through EPnP method. To verify the effectiveness of the proposed onboard visual positioning method, an external visual positioning system (EPVS) based on Kinect is built, and a visual tracking algorithm for rotorcraft is designed. The experimental results suggest that the positioning deviation of the rotorcraft is within 2 mm, and the OVP method is suitable for rotorcraft positioning.
