Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the drawings.

[0036] The present invention provides a simulation method for maneuvering and flying of a near-surface aircraft, such as figure 1 As shown, including the following steps:

[0037] Step 1: Establishment of 3D scene model

[0038] The establishment of 3D scene model mainly includes ocean scene modeling and 3D entity modeling. The ocean scene model includes a wave situation model and an island model, which is one of the key steps in constructing a near-surface aircraft visual simulation platform. In the present invention, the establishment process of the 3D scene model is completed through the process of data analysis preparation, original model generation, terrain optimization, texture mapping and debugging optimization processing. The specific modeling process includes the following steps:

[0039] (1) Obtain the physical appearance and geometric shape data through design drawings and re...

Abstract

The invention discloses a water level-close aircraft maneuvering flight visual scene simulation method, and belongs to the field of computer simulation. The method comprises the following steps of: step one, establishing a three-dimensional scene model; step two, configuring a three-dimensional model and manufacturing a three-dimensional special efficacy; and step three, implementing the simulation process. According to the water level-close aircraft maneuvering flight visual scene simulation method disclosed by the invention, the water level-close aircraft maneuvering flight is subjected to visualization visual scene simulation, the defect that the traditional real object simulation has nonrepeatability and high risk is solved, and the water level-close aircraft maneuvering flight visual scene simulation method has the characteristics of high efficiency, repeatability and low cost; and real ocean geographic information is added in the three-dimensional scene model creation, thus the simulation environment is more real; and the flight posture of air route of individual aircraft can be displayed and deduced, viewing angles can be switched among a plurality of flight air routes of a plurality of aircrafts, and all-dimensional and multi-angle simulation viewing angles can be provided.

Description

Technical field [0001] The invention belongs to the field of computer simulation, and specifically relates to a visual scene simulation technology, in particular to a near-surface aircraft maneuvering scene simulation method. Background technique [0002] Route planning technology is one of the key technologies for near-surface aircraft maneuvering. The route planning system can plan precise flight paths for near-surface aircraft. It is very important to verify the validity and correctness of the route planning results by simulating the planning results of the route planning system. The traditional simulation method for maneuvering flight of near-surface aircraft is physical simulation, which can grasp the performance and movement of near-surface aircraft from a macro perspective. However, this method is expensive to implement and complicated in technology, and cannot be used to determine the performance of near-surface aircraft. Carrying out detailed analysis, this reflects the...
