Display system, related display method and computer program

Abstract

A display system 10 of a device capable of travelling along a path between at least two distinct points and using at least one heading datum comprises: an image sensor (12) for acquiring environmentalimages along the path; an image processing module (14) for determining the drift of the device in real-time; a module (16) for determining information representative of the route taken by the device;a module (18) for real-time determination of the true heading followed by the device, from the information representative of the route and the drift of the device; and a module (20) for returning information representative of the true heading to a user.

Description

technical field [0001] The invention relates to a display system, in particular a head-up display system, head-up or even head-up, included in a device capable of moving between two different points and using at least one heading data. [0002] The invention also relates to a display method implemented by such a display system. [0003] The invention also relates to a computer program comprising software instructions which, when executed by a computer, implement such a display method. [0004] The invention provides many applications, notably the use of true heading to improve the view of a user of a device, where the user is able to monitor the mobile environment and the information provided by the device's instrumentation through the device or by wearing the device. Background technique [0005] Indeed, true heading is an essential element of air, sea, space or ground navigation when the device is housed or embedded in a vehicle (i.e. the displacement of the device corres...

AI Technical Summary

Problems solved by technology

[0009] However, in cases where conformal projections of symbols and / or synthetic heads-up images are superimposed on the mobile environment or on helmet-mounted heads-up images (which must be consistent with the external vision of the traveling environment and require accurate true heading), such heading Inaccuracies can be destructive to the pilot or even the source of error

[0010] For vehicles equipped with only AHRS (Attitude and Heading Reference System), especially certain helicopters or other turboprop aircraft, the projection of head-up or helmet-mounted information is of limited interest due to the inaccuracy of currently obtained true heading
