Abstract
The invention relates to a method for developing a three-dimensional representation of a terrain overflown by an aircraft able to be piloted by a pilot via a control station. The method includes for representation of at least one current terrain element, following steps: determining a first distance between a first terrain element and the aircraft; determining a second distance between a second terrain element and the aircraft; and calculating a resultant display intensity of the current terrain element as a function of a difference between the first distance and the second distance.
Claims10
A method for generating a three-dimensional representation of a terrain overflown by an aircraft able to be piloted by a pilot via a control station, the control station comprising an at least partially transparent display screen and a sensor capable of determining an orientation direction of a head of the pilot, the orientation direction being associated with a predetermined solid angle defining a field of view, the display screen being suitable for displaying the three-dimensional representation and being positioned at least partially in the field of view,
- the method including, for a representation of at least one current terrain element included in the field of view, steps:
- determining a first distance between a first terrain element and the aircraft, a representation of the first terrain element being included in the field of view and the first terrain element being located in a vicinity of the current terrain element;
- determining a second distance between a second terrain element and the aircraft, a representation of the second terrain element being included in the field of view, separate from the first terrain element and the second terrain element being located in the vicinity of the current terrain element;
- calculating a resultant display intensity of the current terrain element as a function of a difference between the first distance and the second distance;
- and
- displaying the current terrain element with the associated resultant display intensity.
A device for generating a three-dimensional representation of a terrain overflown by an aircraft able to be piloted by a pilot via a control station, the control station comprising an at least partially transparent display screen and a sensor capable of determining an orientation direction of a gaze of the pilot, the orientation direction being associated with a predetermined solid angle defining a field of view, the display screen being suitable for displaying the three-dimensional representation and being positioned at least partially in the field of view, the device including:
- a memory;
- a processor coupled to the memory and configured to:
- determine, for a representation of at least one current terrain element included in the field of view, a first distance between a first terrain element and the aircraft and a second distance between a second terrain element and the aircraft, a representation of the first terrain element and the second terrain element being included in the field of view, the first terrain element and the second terrain element being located within a vicinity of the current terrain element, the second terrain element being separate from the first terrain element;
- calculate a resultant display intensity of the current terrain element as a function of a difference between the first distance and the second distance;
- and
- display the current terrain element with the associates resultant display intensity.
