摘　　要：针对飞行条件下加油软管平衡拖曳位置的获取难题,设计了一套基于图像的空中加油软管平衡拖曳位置测量方法。通过在加油机上加装多路高清影像测量系统获取空中加油过程软管的运动图像,并对多像机同步采集、大景深像机标定、无参考点加油锥套识别与跟踪等关键技术进行研究,实现了加油软管平衡拖曳位置的精确测量。仿真实验结果表明,采用该方案测量精度优于5 cm,满足飞行试验精度要求。Aiming at the difficult problem of obtaining the balance towing position of the refueling hose under flight conditions,a set of image-based method for measuring balance towing position of aerial refueling hose was designed.By installing an airborne multichannel and high-definition image measurement system on the tanker to obtain the moving images of the refueling hose in the air refueling process,and researching on the key technologies such as the synchronous acquisition of the multi-camera,the camera calibration with a large depth of field,and the recognition and tracking technology of the refueling taper sleeve without reference point,the accurate measurement of the balance towing position of refueling hose was realized.The simulated experimental results show that the measurement accuracy of this scheme is better than 5 cm,which meets the accuracy requirements of the flight test.
