Embodiment Construction

[0036] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0037] In the present invention, in the absence of a contrary description, the orientation words included in the term, such as "upper, lower, inner, outer", etc., only represent the orientation of the term in the normal use state, or are understood by those skilled in the art colloquial term and should not be construed as a limitation of the term.

[0038] The attitude indicator is an airborne instrument used to indicate the attitude angle information of the aircraft. The attitude angle of the aircraft describes the angle between the body axis system and the ground axis system, including pitch angle, yaw angle and roll angle. The pitch angle of an aircraft ref...

Abstract

The invention discloses a three-dimensional virtual attitude indicator implementation method, the attitude indicator is used for indicating aircraft attitude angle information, an attitude angle of anaircraft describes an included angle between an aircraft body shafting and a ground shafting, the attitude angle comprises a pitch angle, a yaw angle and a roll angle, and the method comprises the following steps: 1, constructing a spatial three-dimensional model for an attitude indicator through sphere modeling; 2, drawing corresponding scale information for the surface of the attitude ball by using a texture mapping technology; 3, adding a space rotation effect to visually display flight attitude angle parameters; 4, applying Blinn-Phong illumination rendering to enhance the spatial stereoscopic impression of the attitude ball; and 5, drawing a dial plate and an auxiliary control. According to the three-dimensional virtual attitude indicator implementation method, the three-dimensionaleffect is obviously enhanced, the man-machine work efficiency is better met, and the airborne display requirement is met.

Description

technical field [0001] The invention relates to the technical field of aviation virtual instruments, in particular to a method for realizing a three-dimensional virtual attitude indicator. Background technique [0002] As an important part of the flight cockpit, the on-board instrument display provides the pilot with real-time flight attitude information and is an important carrier for the pilot to interact with the human-machine. The current airborne instrumentation realizes the integration of computer graphics technology and liquid crystal display technology, and the graphic display of airborne instrumentation has become the main design method of airborne instrumentation. [0003] At present, the implementation method of airborne virtual instrument is mainly based on two-dimensional drawing method, which can no longer meet the current airborne display requirements. Therefore, adding three-dimensional graphic effects to the traditional two-dimensional airborne virtual inst...
