英文摘要：

Autonomous aerial refueling is one of the important supports for the improvement of unmanned aerial vehicle （UAV） combat capacity, and the eagle is famous for its sharp eyesight. Aiming at the accuracy requirement during the docking phase of UAV autonomous aerial refueling （AAR） , the UAV visual measurement methods and a hardware-in-loop simulation platform were designed based on eagle-eye vision mechanism. The visual attention mechanism of eagle eye was adopted to extract the region of interest in virtual scene and perform saliency detection and noise removal. The relative pose of the tanker and unmanned aerial vehicle receiver was measured accurately based on the colored marker recognition of the UAV using P3P algorithm. Based on the above techniques, the autonomous control law of the flying boom was designed with the proportional-integral-differential （PID） controller. The hardware-in-loop simulation platform for unmanned aerial vehicle autonomous aerial refueling was developed in laboratory environment. Series of hardware-in-loop experiment results demonstrate the feasibility and effectiveness of the proposed approach in the biologically eagle-eye vision simulation platform.
