Embodiment Construction

[0015] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] The method proposed by the present invention is actually a typical application combining ultra-large-scale virtual reality technology with modern positioning and navigation technology, and can be used for military helicopters to generate virtual three-dimensional scenes around the outside of the fuselage under harsh visual conditions, providing an intuitive and close to real environment. The visual environment of the external scene can provide an intuitive picture during the flight to reduce the workload of the pilot, and can observe the position and attitude of the carrier aircraft from the perspective of God, and observe the proximity of the carrier aircraft to terrain, mountains, water bodies, etc. during landi...

Abstract

The invention belongs to the field of three-dimensional reconstruction and situation awareness, and discloses a three-dimensional scene real-time updating method in a helicopter-borne environment. Themethod based on synthetic vision technology comprises the steps of airborne inertial navigation equipment and photoelectric aiming line pose data analysis, terrain space transformation matrix construction, multi-view transformation matrix construction and scene node transformation matrix application. Under the driving of the method, the synthesized visual scene can generate an airplane external scene which is continuously updated in real time or an airplane motion scene which is externally observed.

Description

technical field [0001] The invention belongs to the technical fields of three-dimensional reconstruction and situation awareness, and relates to a method for real-time updating of three-dimensional scenes in a helicopter environment. Background technique [0002] The damage rate of helicopters under poor visual conditions has been high all over the world. Statistics from the aviation industry show that the number of helicopter accidents is more than ten times that of fixed-wing aircraft. The U.S. Army lost 130 helicopters to non-enemy fire during the Iran-Iraq War. In 2013 alone, a total of 537 helicopters were lost worldwide. Excluding about 35% of the number of accidents where the cause cannot be found, about half of the remaining number of accidents are related to the environment, including rain, snow, fog, sand and dust, etc. resulting in varying degrees of poor visual conditions. Further studies have shown that any situation that can lead to poor visual conditions, in...
