Description

  The present invention mainly relates to a system for projecting an image to the left and right outward with respect to the traveling direction of a train.

  Conventionally, various video projection systems have been used. However, as shown in this proposal, there is currently no projector that is mounted on a train and projects images on the left and right sides of the train.

A train is a vehicle that travels on a track with a predetermined width, and passes through a suburb or tunnel to reach a destination. When traveling in the suburbs, passengers can enjoy the scenery outside during the day, but the outside is completely dark inside the tunnel. When traveling in this tunnel, it is an innocent time and I am looking forward to getting out of the tunnel quickly, but currently there is no way to enjoy scenery etc. even when traveling in the tunnel, and there are no other meaningful methods Is the current situation.
In view of the above, this plan solves the above-mentioned problems by installing projectors on the left and right sides of the train and projecting the video data built in the data recorder connected to the projectors from the projector toward the inner wall of the tunnel. It was invented for the purpose of providing a means to do this.

As a means for solving the problems, the present plan has the following configuration.
That is, a data storage unit for storing arbitrary video data, a set of control units for controlling the stored data, and a data recorder mounted at an appropriate place in the traveling vehicle, the data The vehicle has a set of controllers for transmitting control commands to the recorder and a plurality of projectors for projecting the video selected by the video signal from the control unit to the left and right sides of the vehicle. The left projection and the right projection can be individually adjusted with respect to the direction. The present proposal is a bidirectional projection system mounted on a traveling vehicle having the above configuration.

This plan has the following effects.
1. Arbitrary images can be projected on the inner wall of the tunnel, and vehicle passengers can enjoy the images.
2. Simultaneous projection can be performed on the left and right sides of the tunnel, so both the right and left seat occupants can enjoy it.
3. Projection only inside the tunnel can be performed by switch operation, and running costs can be reduced.

Hereinafter, embodiments of the present invention will be described.
In the figure, reference numeral 1 denotes a data recorder mounted on an arbitrarily selected vehicle.
A data storage unit 2 is provided in the data recorder. The data storage unit is similar to a hard disk and can store and delete necessary data.
The data is a suburban landscape video, a commercial message video, or any other video. Reference numeral 3 denotes a right control unit that controls a projected image. This right control part is a part which controls the image | video projected to the right toward a train advancing direction, Comprising: Artificial control is made | formed by the controller 4 connected to this right control part. Adjustments such as the amount of light of the image, the projection range angle, the focal length adjustment, the hue, brightness, and saturation of the image are made.
5 is a similar left control unit, and 6 is a controller. 10 is a right projector, 11 is a left projector. For convenience of explanation, the number of projectors is limited.
These projectors are installed in a non-projecting state with respect to the train outer surface.

Images from these projectors are projected outside the train. In Japan, in the case of a double track, the train travels on the left side, and the left projection and the right projection are different as shown in FIG.
That is, the left projection is a wide angle projection because the distance from the projector to the inner wall of the tunnel is short, and the focal length corresponds to that distance. On the other hand, right projection is a projection in a narrow angle range because the distance from the projector to the inner wall of the tunnel is long, and a focal length corresponding to that distance. Further, the amount of projection light is also set according to this distance.
The number of projectors and the interval between adjacent projectors are set according to the vehicle length.
In practice, a switch is provided in the driver's seat, and all the vehicle projectors are turned on and off by this switch operation. That is, when a train enters the tunnel, projection starts when the switch is turned on, and when the train exits the tunnel, projection ends when the switch is turned off.

That is, when the switch is turned on, the control unit in the data recorder operates to send the data in the data storage unit to the projector, and the image is projected outward from the projector. This projection is preset in advance by controller adjustment, and optimal projection is performed.
Also, as shown in the figure, the left projection and the right projection are projected with adjustments adapted to this difference because the distance to the tunnel inner wall is different.
People basically don't like darkness. This is an instinct from the beginning.
Lighting has been invented with the passage of time, and a bright environment has been obtained, but the range of use is limited, and there is basically no lighting in the tunnel.
It is also necessary for people to check the environment where they are located, and there are always windows in houses and traffic vehicles, which can be used to check the external situation. Can not.

However, in this proposal, since various images can be projected on the inner wall of the tunnel, visual interest and a sense of security can be obtained. As a projected image, both a still image and a moving image are possible, but various contents as described below are possible.
1. By projecting a video of the scenery at that location outside the tunnel in the tunnel, you can feel that you are traveling in the suburbs even inside the tunnel.
2. Project domestic or overseas famous places and scenic shot videos or still images.
3. Project a commercial image of a company as a video or a slideshow still image.
4). Project movie trailers for movies and dramas.
5). Project a manner-invoking activation picture in daily life
6). Real-time image information is projected using a separate tuner connection.
The above is an example, and various other uses are possible.

The number of projectors used in the present plan and their installation intervals are arbitrarily determined, and examples thereof are shown in FIGS. In both figures, the projection to the left is the same, but in the projection to the right, FIG. 5 shows an example in which the installation locations are the same on the left and right, and FIG.
In either case, the installation interval and the projection angle range are preset so that the projection is not fogged.
Since the inner wall of the tunnel is a curved surface, it is preferable to use a curved surface projector, thereby eliminating the distortion of the projected image.
Recently, the opening of a new Shinkansen has become a hot topic, but there are cases where the Shinkansen has many tunnels, and it seems that this projection system is effective in such cases.
In addition, although this plan is intended for use on trains, it can also be used on other vehicles.
As described above, according to the present invention, it is possible to obtain a device that can achieve visual satisfaction in the tunnel.
