Application of vision-based UAV landing hardware-in-loop simulation system

In order to resolve the problem that it is too hard to test and verify all kinds of vision-based unmanned aerial vehicle (UAV) landing algorithms, a new method which is the design and application of the vision-based UAV landing hardware-in-loop (HIL) simulation system is presented by adopting graphical modeling language, real-time extension (RTX) based on Windows OS and virtual reality (VR) technology. The real-time simulation platform constructed with this method can verify all kinds of vision-based UAV landing algorithms and reveal the bug and defect of these algorithms. It provides an efficacious approach to test and verify vision-based UAV landing algorithms. Meanwhile, the method provides technique supports for the application of vision-based UAV landing algorithms in practice in future.
