Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a simulated visibility device for an exercise experience simulator for reproducing scenery seen from, for example, an aircraft, a ship, a vehicle, etc. while being manipulated artificially.

[Conventional technology]

BACKGROUND ART Conventionally, a simulated visibility device for an exercise experience simulator has been known that reproduces the scenery seen from an aircraft, ship, vehicle, etc., and is operated by artificially moving it. As shown in FIG. 3, this type of device projects an actually photographed landscape image from a projector 10, and displays it on a transmission screen 13 at step 1112. The mirror 12 is connected to a motor 15 that rotates in the vertical direction and a motor 16 that rotates in the horizontal direction. The image projected on the screen 13 is smaller than the image projected from the projector 10. Now, when the viewer A who is looking at the image projected on the screen 13 wants to move the image, the drive motor 15, the drive motor 1
6, the mirror 12 rotates accordingly,
For example, a landscape image taken from a moving car is displayed, and when the viewer A who is looking at the landscape image turns the steering wheel as if he were the driver, the drive motor 16 is linked to the steering wheel. rotates, and the scenery moves left and right. In this way, viewer A can see the screen 13.
The projected image can be viewed while being artificially moved. However, with a method like this device in which the reflection angle is changed by mechanically driving the boundary to move the image, there is a limit to the ability to reproduce images that change rapidly or images that change rapidly. Also,
As the mirror 12 moves, the optical distance to the screen 13 changes, causing image deterioration such as image distortion and out-of-focus. Furthermore, with the above-mentioned device, although the image can be moved up and down and left and right, it is not possible to rotate the image, so a sufficient visual effect cannot be obtained. On the other hand, there is a device that synthesizes images using a computer and displays the synthesized image on a screen. With such a device, it is possible to not only move the image up and down and left and right, but also rotate the image. Moreover, modern computers have fast processing speeds, so they can handle fairly fast movements. However, since the images projected by this device are originally composite images, they are far from the actual scenery.

[Problem to be solved by the invention]

The present invention was made in view of the above, and uses an actual landscape image as an original image, and can not only move the image up and down and left and right in response to the fast movement of the landscape, but also rotate the image. A simulated visual field device for an exercise experience simulator is provided.

[Means to solve the problem]

A simulated visual field device for an exercise experience simulator to which the present invention is applied in order to solve the above problems will be explained with reference to FIG. 1 corresponding to an embodiment. As shown in FIG. 1, the simulated visual field device for an exercise experience simulator according to the present invention sequentially moves the portion of the projected image from the video reproducing device 1 that reproduces the real image, thereby changing the projected image on the screen. It is a device that can be moved. Its essential configuration is that the control device 3 converts the movement of a portion of the projected image designated by the operating device 2 into an address signal on the projected image. A portion of the time-series video scanning signal of the projected image output from the video reproduction bag fil, which follows the address signal, is selected by the image processing device 4 as a projected image signal and stored in the temporary storage device 15. The projection image signals sequentially retrieved from the temporary storage device 5 are made into visible images by the display device 6, and the visible images are projected onto the screen 9.

【Example】

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram of an embodiment of a simulated visibility device for an exercise experience simulator to which the present invention is applied, and will be explained by giving an example in which this device is used for a simulated operation of a helicopter. In the figure, l is a video playback device, 2 is an operation device, 3 is a control device, 4 is an image processing device, and 5 is a temporary storage device Video R
AM, 6/7/8/9 display device. The video playback device l is a video laser disc device (VLD).
), this video laser disc device reproduces images on a video laser disc in which real landscapes taken with a video tape camera are dubbed, and generates time-series video scanning signals. An entire shot of a landscape image taken with a videotape camera from the front window of a helicopter is indicated by V in FIG. Preferably, the overall landscape image V has a wider angle of view than the field of view that can be seen by a person from the front window of the helicopter. The controller 2 is a simulated control stick mounted at a corresponding position on the simulated control device 1. For example, when the simulated control stick is tilted to the right, a partial image within the overall landscape image V is rotated to the right. A signal appears. That is, a signal designating the range of the partial image to be cut out from the entire landscape image V shown in FIG. 2 is output. The control device 3 converts a signal specifying the range of the partial image into an address signal on the projected image by operating the operating device 2. The address signal is the column address (0, 1, 2
, 3,..., ml, row address (0, 1, 2, 3°・
, nl digital signals. The image processing device 4 extracts, from among the time-series video scanning signals of the projection images output from the video laser disc device 1,
Signals within the range of the address signal issued by the control device 3 are selected and re-edited as a projection image signal. The temporary storage device 5 is a video RAM, which sequentially stores the edited video signal and stores it as a signal for each screen. The display devices 6, 7, 8, and 9 are composed of a cathode ray tube device 6, a projection lens 7, a concave mirror 8, and a transmissive screen 9, and the transmissive screen 9 is arranged at a position corresponding to the front window of the simulated pilot device. In the simulated visual field device for the exercise experience simulator of this example,
As shown in FIG. 2, when a wide-angle overall landscape image V is actually photographed, the center portion of the entire landscape image V is displayed on the transmissive screen 9 if the simulated control stick is upright. When the simulated control stick is tilted to the right, the image rotates to the right by an angle θ as shown by vl, and is displayed on the transparent screen 9. In addition to simply rotating the image as in the above embodiment, it is also possible to cut out and display the entire landscape image V from any position without rotation, as shown in (2) and v3 in Figure 2. It is also possible to display images by enlarging or reducing them.
