Foreign studies have shown that the carrier-based aircraft landing on the aircraft carrier is the most difficult stage in the process of taking off and landing, and BHI often appears. 国外研究表明,舰载机在航母上降落是起降过程中难度最高的阶段,同时出现的错觉类型尤以黑洞错觉为主。
Traditional winglets are designed mainly for the cruising stage, while the effects of winglets in the climbing/ landing stage are not as significant. 传统翼梢小翼主要针对巡航状态设计,无法在起降、爬升阶段提供最佳减阻效果。
China is also at the manned lunar landing project pre-feasibility study stage. In the course of the lunar landing, the rendezvous and docking is essential between lunar landing compartments, and the docking dynamic simulation in the manned moon landing project is also extremely important. 在登月过程中,奔月轨道级之间的交会对接是必不可少的,而对接过程的动力学仿真在载人登月工程中也显得尤为重要。
Therefore, in this paper, a vision-based navigation system is researched and designed, which is responsible for the output of the position and attitude information required during the spot landing stage, and lays the research foundation for the implementation of autonomous landing on the mobile platform. 为此,本文研究并设计了基于视觉的导航系统,负责输出定点降落中所需的位置姿态信息,并为下一步在移动平台上实施自主降落奠定研究基础。
