Embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to invention:
In Fig. 1, display module in virtual reality module, data acquisition module, the cabin, all be to finish by the hardware facility that is installed on the aircraft, the pilot is the startup person and the effector of system.The main modular of system is the virtual reality module, it is sent to the real time modelling image of actual environment the display of being presented in face of the pilot, can allow the true change in location that must experience aircraft with respect to the airport of pilot, help that the pilot is better must to finish the landing process, realize the aircraft stable landing.
Fig. 2 and Fig. 3 are based on the workflow diagram of the aircraft stable landing method of virtual reality technology.
At first, when aircraft advanced near landing, the pilot started auxiliary landing system, promptly realized the stable landing of aircraft by virtual reality technology.
Secondly, computer run virtual reality software, the range data of comprehensively passing back and be pre-stored in airport and airplane data in the computing machine simulates the relative position of current aircraft and airfield runway, finishes virtual reality.Be the workflow diagram of virtual reality processing module as shown in Figure 3, when the pilot opens this auxiliary landing system, computing machine is earlier according to the airport data that are preset in the internal memory, finish the generation of airport environment, and the aircraft three-dimensional model of in the scene of airport, packing into, distance measuring sensor is set starts working, this has just finished the initialization for this system virtualization reality.Enter the instant virtual process of computing machine then for reality, computing machine reads the landing wheel that records and the distance between the ground, actual range and the relation of the distance proportion in the three-dimensional scenic according to measuring and calculating in advance, draw model aircraft new position data in scene, upgrade the position of three-dimensional model aircraft with respect to the airport virtual scene.After having finished the once renewal for the aircraft three-dimensional model, read the distance measuring sensor data once more, up to the aircraft stable landing, the pilot closes the landing backup system.
