【 摘 要 】
[Objectives]The spatial position of carrier-based aircraft on the deck is required before take-off. Visual measurement is a high-precision and high-efficiency automated measurement method.[Methods]Therefore, a spatial positioning scheme for the carrier-based aircraft based on visual measurement is proposed in this paper. Firstly,the "Visual Measurement System-Deck Plane" relative position calibration method is introduced;secondly,based on the collinear relationship of "Visual Measurement Camera-Imaging Center-Fuselage Cooperation Logo",the position of the cooperation logo relative to the visual measurement system is calculated;finally,on this basis,the fuselage fixed cooperation logo is identified as a position transfer relay station to obtain the non-visual environment "Visual Measurement System-Airborne Inertial Navigation" transfer measurement model.[Results]The results of the visual measurement experiments show that the target spatial positioning result based on visual measurement is better than 0.3 m.[Conclusion]This scheme is expected to enable more carrier-based aircraft sorties to obtain spatial positioning information with higher precision before take-off.
