Abstract

PURPOSE:To widen the moving target recording extent of a pilot, by moving a display section in which a collimating lens and combining glass are united in one body in accordance with correcting signals. CONSTITUTION:An X- and Y-deflection signals converted at a symbol signal generator 1 are corrected at a center position corrector 6 which generates correcting signals for fixing the symbol of a moving target onto an X- and Y-axes and sent to a CRT2, and then, sent to a display 7, in which a collimating lens and combining glass are united in one body and to which a moving function is added, through an optical fiber symbol transmitting section. Then the display 7 is moved to a position, at which a symbol corresponding to the moving target is displayed, in accordance with the signals, whose center positions are corrected at the center position corrector 6. Therefore, the moving target can be displayed on the display 7 in a wide extent and, as a result, the front visual field of a pilot can be widened extensively.

Description

[Detailed description of the invention] The present invention relates to a head-up display device.

Conventionally, this type of head-up display device has a first
As shown in the figure, the information acquired by each sensor on the machine is converted into Y-axis and Y-axis deflection signals by the symbol signal generator 1, and displayed as symbols on the CRTZ.
The symbol displayed on the RT 2 is transmitted to the scicollimating lens 4 by a symbol transmission unit 3 such as a relay lens group or an optical fiber, and is displayed on a compiling glass 5 fixed at a specific position in front of the pilot's line of sight. is,
To make symbols necessary for flight etc. visible to pilots. Since the compiling glass 5 of the head-up display device is fixed, the symbol indicating the moving target disappears from the compiling glass when the target moves. That is, as shown in FIG. 2, the field of view θ from the pilot's viewpoint P. In the head-up display device, a target T1 in front of the pilot's viewpoint P has a field of view θ. within the target Tt
The symbol S1 corresponding to is displayed on the compiling glass 5, but the target T1 moves to the target
. When the symbol 82 falls outside the target T2, the symbol 82 disappears from the compiling glass 5.

The present invention eliminates the above drawbacks, and in a head-up display device, corrects the X-axis and Y-axis deflection signals by using a center position corrector, and integrates the lens, collimating lens, and compiling glass into one unit. To provide a device capable of displaying a symbol of a moving target over a wide range on a compiling glass by moving a display part in accordance with a correction signal, thereby widening a pilot's visual range of a moving target. .

A head-up display device according to the present invention includes a central position corrector, a display device that integrates a compiling glass, and a collimating lens, and an optical fiber symbol transmission section.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 3 is a basic block diagram of the present invention.

In FIG. 3, symbol signal generator 1. Since the CRT 2 is all the same as in FIG. 1, detailed explanation will be omitted. Third
In the figure, X converted in symbol signal generator 1
, Y deflection signal, the symbol of the moving target is
Alternatively, the center position is corrected by a center position corrector 6 that generates a correction signal for fixing the image on the Y axis, and sent to the CRT 2 via an optical fiber symbol transmission unit 8 to combine a collimating lens and a compiling glass into one unit. The display 7 moves to the position where the symbol corresponding to the target is displayed, based on a signal which is sent to the display 7 which has an added moving function and whose center position is further corrected by the center position corrector 6. FIG. 4 is a diagram for supplementary explanation of the present invention, and shows a plan view when the target moves from the center position f4 to the left and further to the right. In FIG. 4, there is a target '13 moving ahead of the pilot's viewpoint P, and a symbol S3 corresponding to the target T3.
is displayed on the display 7. When the target T3 moves to the target T4, the center position corrector 6 corrects the deflection signal and sends a signal to the display 7 to move the display 7. When the target T4 moves to the target T5, the center position corrector 6 similarly generates a correction signal matching the movement angle α2, and sends it to the CRT 2 and the display 7.
A symbol S5 corresponding to the target T5 is displayed on the display 7.

That is, the visual field in which the symbol corresponding to the target can be visually recognized by the pilot is the visual field θ in the fixed state shown in FIG. From, θ. It is expanded to +θyo+θ.

As explained above, the present invention displays a moving target over a wide range by configuring a head-up display device with a center position corrector, a moving display, and an optical fiber symbol transmission section. This has the effect of realizing a head-up display device that can be displayed on the vehicle and significantly widen the pilot's forward field of view.
