Helicopter navigation method, three-dimensional scene image generation method, device and equipment

Abstract

The invention provides a helicopter navigation method, a three-dimensional scene image generation method and device, and equipment, and relates to the technical field of three-dimensional reconstruction. The method comprises the steps of obtaining a current position of a helicopter; reading a target three-dimensional image of an area to which the current position belongs from a pre-generated three-dimensional scene image; and displaying the target three-dimensional image, and displaying an icon of the helicopter at a corresponding position in the target three-dimensional image according to thecurrent position. According to the scheme, the target three-dimensional image corresponding to the current position of the helicopter can be read from the pre-constructed three-dimensional scene image, and the icon of the helicopter is displayed in the target three-dimensional image, so that a driver can grasp the three-dimensional geographic information and the surrounding situation of the current flight position more visually; the flight parameters and flight path of the helicopter can be adjusted in time to realize auxiliary navigation of the flight path of the helicopter, and the purposeof improving the safe flight of the helicopter in the area is effectively achieved.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional reconstruction, in particular, to a helicopter navigation method, a three-dimensional scene image generation method, device and equipment. Background technique [0002] Helicopters have irreplaceable advantages in low-altitude flight such as emergency rescue, earthquake relief, agricultural and forestry spraying, air patrol and power line patrol. Therefore, the use of helicopters is becoming more and more widespread. Compared with large-scale flying equipment, helicopters are limited in both software and hardware capabilities. [0003] At present, due to the limitations of software and hardware capabilities, helicopters mainly rely on the pilot's visual flight when performing low-altitude flight tasks. Specifically, the driver judges the surrounding environment with naked eyes and controls the flight direction of the helicopter. [0004] But, adopt existing technology, when fl...

Problems solved by technology

[0004] However, with the existing technology, when flying at night or in weather conditions with low visibility such as heavy fog, the safety of helicopter flight will be reduced
