<p>The invention concerns a visual restitution device with 3 window large fields for visual restitution providing an artificial visual environment of flight simulator and more particularly for a helicopter. The invention is characterised in that with only 3 windows it provides very great visibility pattern and it also provides a simple and inexpensive solution to a complex problem. Its horizontal field very easily attains ?110°. Its front vertical field reaches up to +90°. Its lateral fields reach down to 70°. The device is based on a structure of right angles, arranged in a specific manner, and enabling an the whole field of vision to be inscribed within the images. In accordance with the principle of overhead projection, the observer, in schematic eye position, is located somewhere inside said volume and sees each of the 3 faces beneath the horizontal and vertical fields which form large base viewing pyramids. In fact he is immersed in the action. The concept can be used for all simulation systems requiring restitution of visual environment: 1) replacing a sphere site; 2) any form of visual restitution with 3 windows for various simulators: aeroplanes, cars, ships, for sports, such as skiing/bobsleigh/ canoeing and the like; 3) virtual reality for architect firm, exhibition parks and the like.</p> |
