Multi-screen dynamic viewpoint system for helicopter simulator
Helicopter equipment plays a more and more important role in military and civil fields by virtue of its high maneuverability, takeoff and landing without terrain restrctions, hovering operation, so it is particularly necessary to train pilots’ operational skills for the wider use of helicopters. Nowadays, with the rapid development of virtual reality technology, the helicopter simulator technology has become a research hotspot in this filed. However, creating a driving environment with high sense of presence is the difficulty of simulator research. This paper proposed a multi-screen splicing technique based on dynamic viewpoint which added the driver’s head posture estimation. Firstly, the sensor technology was used to track the pilots’ head pose information in real time. Secondly, the rough estimation algorithm based on KALMAN enhancement and the precise estimation algorithm based on ICP of the driver’s pose was designed, then the position and angel of the viewpoint in the virtual scene are dynamically updated according to the pilots’ head pose. Moreover, the screen splicing method under dynamic viewpoint was also studied. The method proposed in this paper not only made the virtual scene change with the change of drivers’ head pose, but also provided the virtual scene from a large perspective, so as to the visual sense of the simulator was improved. The validity of the proposed algorithm was verified by four experiments in this paper.
