Aspects of the disclosure provide fuel receptacle position/pose estimation for aerial refueling (derived from aircraft position and pose estimation). A video frame (200), showing an aircraft (110) to be refueled, is received from a single camera (108). An initial position/pose estimate (506) is determined for the aircraft (110), which is used to generate an initial rendering (418) of an aircraft model (416). The video frame (200) and the initial rendering (418) are used to determine refinement parameters (440) (e.g., a translation refinement (442) and a rotational refinement (444)) for the initial position/pose estimate (506), providing a refined position/pose estimate (508) for the aircraft (110). The position/pose (622) of a fuel receptacle (116) on the aircraft (110) is determined, based on the refined position/pose estimate (508) for the aircraft (110), and an aerial refueling boom (104) maybe controlled to engage the fuel receptacle (116). Examples extract features from the aircraft (110) in the video frame (200) and the aircraft model rendering, and use a deep learning neural network (NN) to determine the refinement parameters (440).
