Method of display and system for aiding navigation

A method for displaying images on respective screens of at least two headsets of a system for aiding navigation, wherein the system further comprises a plurality of cameras capable of acquiring at least one image of a part of an environment and a calculator, the method comprising, for each screen, the successive steps of:

• receiving by the calculator images of the part of the environment acquired by the plurality of cameras;
• merging the images derived from the plurality of cameras to obtain a merged image of the part of the environment;
• determining a first orientation of the headset worn by an operator, the determination of the first orientation of the headset of the operator taking place at a first instant prior to extracting a part of the merged image;
• extracting the part of the merged image to obtain a first image, wherein the extracting the part of the merged image is a function of the determined first orientation of the headset of the operator;
• processing the first image having a first number of pixels to obtain a first processed image, the first processed image being an improved quality of the first image;
• measuring a second orientation of the headset worn by the operator, the measurement taking place at a second instant after processing of the first image;
• extracting a part of the first processed image as a function of the second measured orientation of the headset to obtain a second image having a second number of pixels that is less than the first number of pixels;
• and
• dispatching by the calculator to the headset the second image for display on the screen.

A navigation aid system for aiding navigation for a vehicle comprising:

• at least one headset comprising a screen;
• a plurality of cameras capable of acquiring at least one image of a part of an environment;
• and
• a calculator;
• wherein the calculator is configured to do the following for each headset furnished to an operator during said aiding of the navigation of the vehicle:
• receive images of the part of the environment acquired by the plurality of cameras;
• merge the images derived from the plurality of cameras to obtain a merged image of the part of the environment;
• determine a first orientation of the headset worn by the operator, the determination of the first orientation of the headset of the operator taking place at a first instant prior to extracting a part of the merged image;
• extract the part of the merged image to obtain a first image, wherein extracting the part of the merged image is a function of the determined first orientation of the headset of the operator;
• process the first image having a first number of pixels to obtain a first processed image, the first processed image being an improved quality of the first image;
• measure a second orientation of the headset worn by the operator, the measurement taking place at a second instant after the processing of the first image;
• extract a part of the first processed image as a function of the second measured orientation of the headset to obtain a second image having a second number of pixels that is less than the first number of pixels;
• and
• dispatch to the headset the second image for display on the screen.

A vehicle comprising a navigation aid system for aiding navigation of the vehicle, wherein the system comprises:

• at least one headset comprising a screen;
• a plurality of cameras capable of acquiring at least one image of a part of an environment;
• and
• a calculator;
• wherein the calculator is configured to do the following for each headset furnished to an operator during said aiding of the navigation of the vehicle:
• receive images of the part of the environment acquired by the plurality of cameras;
• merge the images derived from the plurality of cameras to obtain a merged image of the part of the environment;
• determine a first orientation of the headset worn by the operator, the determination of the first orientation of the headset of the operator taking place at a first instant prior to extracting a part of the merged image;
• extract the part of the merged image to obtain a first image, wherein extracting the part of the merged image is a function of the determined first orientation of the headset of the operator;
• process the first image having a first number of pixels to obtain a first processed image, the first processed image being an improved quality of the first image;
• measure a second orientation of the headset worn by the operator, the measurement taking place at a second instant after the processing of the first image;
• extract a part of the first processed image as a function of the measured orientation of the headset to obtain a second image having a second number of pixels that is less than the first number of pixels;
• and
• dispatch to the headset the second image for display on the screen.
