Problems solved by technology

[0002] The existing wide-angle infinite view display system at home and abroad cannot change the imaging distance of obliquely looking down. This is because the relative position between the rear projection screen with a scattering layer and the reflector is fixed, so that the pilot is in the system. When observing at the exit pupil, the visual distance is a fixed value, so that it is impossible to truly simulate the change of the visual distance of the pilot squinting down due to the change of the distance between the aircraft and the ground when the aircraft takes off and lands, so that the pilot can use the existing wide-angle infinite Training under the visual display system can not feel the visual change of the oblique viewing distance when the aircraft takes off and lands, which greatly affects the effect of take-off and landing flight training

Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0020] The oblique downward viewing distance variable wide-angle infinite view display method of the present invention is to change the oblique downward viewing distance by moving the distance between the diffuse reflection soft film screen 3 attached to the rear projection screen and the outer surface of the rear projection screen 2 . The continuous movement of the imaging distance adjustment mechanism realizes the continuous change of the distance between the diffuse reflection soft film screen and the rear projection screen, so that the visual imaging distance of oblique downward vision also changes gradually. On the premise of ensuring that the forward-looking and upward-looking visual imaging distances of the system are infinitely constant, changing the distance between the diffuse reflection soft film screen and the rear projection screen realiz...

Abstract

The invention discloses a changeable inclined-lower-vision vision distance wide-angel unlimited sight displaying method and a displaying system which continuously change a distance between the lower end of a back projection screen and the lower end of a reflector focal plane so as to realize the continuous changing of the vision distance of inclined-lower-vision. The changing process simulates the vision changing of inclined-lower-vision of the rising-landing process of aircrafts according to the vision changing rule of the rising-landing process of aircrafts and naked-eye visual rule, so as to enhance the training effect of flight training and in particular to the rising-landing process. The invention adopts a diffuse reflection flexible film provided with elastic deformation capability to be attached onto the outer surface of the back projection screen so as to realize the continuous changing of the distance between the lower end of the diffuse reflection flexible film and the lowerend of the back projection screen in virtue of the continuous movement of an imaging-distance adjusting mechanism, so as to result in the gradual changing of the vision distance of inclined-lower-vision, namely, to realize the changeable imaging-distance of the inclined-lower-vision through changing the distance between diffuse reflection flexible film screen and the back projection screen.
