DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following is a description of a navigational status display and guide device as an embodiment of the present invention with reference to the drawings. FIG. 1 is an explanatory view schematically showing a related state of its constituent devices, and FIG. 2 shows a flow of its operation. It is a block diagram shown.

As shown in FIG. 1, a large number of satellite images are taken to fill the planned route of a liner as a vehicle.
It is processed by the image scanner 1 and is stored in the photograph data storage means 2 with a name so that it can be individually distinguished. Each photograph data stored at this time is displayed on the computer screen, and the actual accurate latitude / longitude information written on the artificial satellite photograph is used, and the latitude / longitude is calculated from the latitude / longitude using the relation of spherical surface → plane projection. The conversion 7d for screen coordinates is obtained, and its input is performed by the keyboard.

[0008] Also, a plurality of voice guidance data about nearby islands and coastal areas along the planned route are input by the microphone 3 and the recording tape 4 and are named and stored so that they can be individually distinguished. It is stored in the means 5. In addition, the coordinates of the boundary with each photograph and the coordinates of the boundary of each audio data on the regular route are input in advance to the program of the selection unit 7a using the keyboard. As a result, the regular route is divided and the name of the photo or audio data corresponding to each segment is assigned.

Next, during the navigation of the liner, the navigation instrument 6 measures the latitude and longitude, the speed and the azimuth of the current position of the ship. Then, as shown in FIG. 2, the main body computer 7 uses the positioning data of the ship including the measured values of latitude and longitude obtained from the navigation instrument 6 to select the ship 7 from the photo data storage means 2 by the selection unit 7a. Select the photo data whose name includes the position. The selection unit 7a is also configured to select required voice guidance data in the same manner from the voice guidance data storage means 5 based on the measured value. Further, the main body computer 7 is provided with a conversion unit 7b for converting the measured values into coordinates on the photographic data.

The main computer 7 has an image synthesizing section 7c.
The image synthesizing unit 7c also includes a selecting unit 7a.
Based on the information from the nautical instrument 6, it is possible to display not only the position of the ship but also the direction and speed of the ship on the photo data selected in, and further display the date and time using the internal clock of the main computer 7. Image synthesis is performed so that the image can be displayed. An image display voice output unit 8 is provided for displaying the image data synthesized by the image synthesis unit 7c as an image and outputting the voice guidance data selected by the selection unit 7a by voice.

Since the navigation status display guide device as one embodiment of the present invention is constructed as described above, the photograph data storage means 2 is based on the own ship's positioning data obtained from the navigation instrument 6 during navigation. The selecting section 7a operates to select the photo data including the own ship position from the selecting section 7a.
In a, required voice guidance data is also selected based on the positioning data. Then, the conversion unit 7b performs an operation of converting the measured values of the latitude and longitude of the ship position into coordinates on the computer screen.

In this way, the photographic data selected by the selecting unit 7a and the position coordinates of the own ship converted by the converting unit 7b are combined by the image combining unit 7c, and the image display sound output unit 8 is displayed.
The image is sent to and displayed as an image, and an appropriate character (a figure in which the plane shape of the hull is made into a figure, etc.) is used for displaying the position coordinates. Further, when the required voice guidance data is selected from the voice guidance data storage means 5 based on the above-mentioned positioning data and the image display voice output section 8 receives the signal of the voice guidance data selected in this way, the same is output. The voice message will be broadcast from the department through the speaker 8a.

As is clear from the present embodiment, according to the above-mentioned navigation status display guidance device, it is possible to generate an artificial satellite photograph without requiring a great deal of time and labor to create map image data as in the conventional case. It becomes possible to input data corresponding to map image data into the computer 7 of the main body, and since satellite images are used in this embodiment as compared with the case of the conventional pictorial map, navigation of the own ship is possible. Passengers will be given a real sense of reality as if the driving situation was taken from an artificial satellite.

[0014] Then, since voice messages about the islands in the vicinity of the own ship, etc. that are advancing momentarily on the image of the satellite image are broadcast, passengers can confirm the current situation by comparing with the actual scenery from the own ship. There is also.
