Method for presenting spatial attitude and heading information of a vehicle

摘要

A method of presenting attitude and heading information of a vehicle on a display to a viewer inside the given vehicle, comprising the steps of: using a 2D display, using data provided by an inertial reference system, using a computer and graphical software for treating the data and defining graphical elements, depicting the graphical elements in 3D on the 2D display, and presenting the attitude and heading information on the 2D display by associating them to at least one graphical element.

1. A method of presenting attitude and heading information of a vehicle on a 2D display to a viewer inside the vehicle, comprising the steps of:
using data provided by an inertial reference system, using a computer and graphical software for treating the data and defining 3D graphical elements, depicting the 3D graphical elements on the 2D display, presenting the attitude and heading information of the vehicle on the 2D display by associating the information to at least one 3D graphical element, depicting a first graphical element as a transparent sphere representing a fixed reference system with respect to the inertial reference system for the movement of the vehicle, the sphere including longitudinal and lateral markings on its surface representing direction and orientation references, an upper half sphere representing the sky, and a lower half sphere representing the ground, projecting movable heading information in response to variations in heading on the surface of the sphere, using a second graphical element which is fixed with respect of the vehicle, representing a 3D reference symbol of the vehicle and/or main axes of the vehicle and/or an orientation plane of the vehicle, placing the 3D reference symbol in the sphere, moving the 3D reference symbol inside the fixed sphere with regard to the vehicle's movement in the inertial reference system, depicting the graphical elements in a vehicle external observer viewing mode, and using for the 3D reference symbol an additional half sphere placed inside the sphere and whose plane surface constitutes the orientation plane comprising a vehicle representation.
