Abstract

PURPOSE:To understand a course more effectively by displaying sceneries of respective points on the course on a display device and providing a printer which prints the sceneries together with the course. CONSTITUTION:The display device 6 displays the sceneries of the respective points on the course and the printer 7 prints the sceneries together with the course. A central processing part 3 calculates the shortest path to a destination and pieces of image information on the respective sceneries are read out of a data base 4 along the course and displayed on the display device 6. Scenery images which are reduced are inserted into a map image at marked places and the composite map image is printed out on paper by using the printer 7. Consequently, the course is understood more effectively.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Application of Industry-L The present invention relates to a route guidance device used by people whose route to a destination is unclear.

(Explanation) Conventional technology In the past, when giving directions at a police box etc., the person answering the questions was usually Iruma. In addition, on guidance devices such as those installed at tourist information centers, by selecting the name of the place from among the buttons prepared in advance, you can select the name of the place on the map. A method was used in which lights and other lights were turned on to determine the positional relationship between the current location and the destination.

However, with such a method, for people who are unfamiliar with the area, there is a large gap between the recognition on the map and the recognition in the actual landscape.

Also, if the route is simple, it may be fine, but if the route is complicated, please provide information about the route and landmarks that were explained to you or read by yourself using a map! As the amount of information increases, problems arise such as forgetting these items or making the mutual relationship between the routes or one quick question unclear.

Furthermore, in order to prevent such problems, the map should be
There are 41Pl for copying on paper etc. by yourself! bawl.

(c) The problem to be solved by the present invention is to understand the route in road guidance by directly measuring the wind around the actual route, and by visually interpreting the visual perception of people who are uncertain about the route. @ of what to present to
It is designed to more effectively understand the route for people who are unclear about the route.

(d)! ! Means for Solving the Problems The present invention provides a route guidance device for guiding a route from a starting point to a destination, which includes a display device for displaying a guide map from the current point to the destination. The scenery at each point on the route is displayed, and it has a printing device that prints the scenery along with the route.

1 E) Function The route guidance device according to the present invention not only displays a map but also displays surrounding scenery along the route, and also prints and outputs a map with scenery of places that can serve as landmarks inserted into the map.

(F) Example Hereinafter, an example of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a block diagram of a route guidance device according to the present invention. (1) is a microphone that receives the sound emitted by the unknown item, (2) is a voice recognition unit that recognizes the sound received by microphone (1) as language, and (3) determines the destination from the recognized input. , map data and route scenery S* data are stored in the database section (4
This database m(4) is a central processing unit that extracts data in a compressed state by accessing the database m(4), and a large amount of compressed map data and landscape image data for directions is managed by CI. (5) centrally processes the data extracted by the database unit (4)
According to the control in 3), restore the compressed data to the original image and display that image on the -1 screen, or insert a static + I image of the location marked 11 on the map image. , print the composite image - fI-Jl! (6) is a display for displaying map images and scenic images for directions, (7) is a printer for printing map images or landscape images, and (8) is for human power other than voice human power.ii (This is a keyboard that falls under the category of auxiliary human-powered device for the purpose of

Next, the operation of the route guidance device of this embodiment will be explained.

The voice containing information representing the destination uttered by the guide n is manually input to the device of the present invention through the microphone (1). The human-generated speech is recognized as language by the speech recognition section (2), and the information is sent to the central processing section (3). The central processing unit (3) identifies the address or name of the received language information and sends it to the database unit (3).
4) Arrange in the cedar style as search information when accessing. Then, when accessible search information is obtained, the database section (4) is accessed. The database unit (4) stores landscape images and map data for directions in a compressed state, and data matching the manually searched information is output to the central processing unit (3). .

First, as the first floor of the first P, map data corresponding to the destination is read out by the database section (4).

The read map data is stored in the central processing unit (3) and sent to the image processing unit (5), where it is restored into a map image. Then, the result is displayed on the display (6)L, and the map is presented to the guide n.

In the next step, the central processing unit (3) calculates the shortest route to the destination based on the obtained map information, and image information of each landscape along the route is read out from the database unit (4). The plural pieces of image information that have been read out are sequentially sent to the image processing section (5), restored, and displayed on the display (6). At this time, by rapidly repeating the restoration and display of multiple image information according to the route,
A moving image is displayed in the human mouth as if it were being reproduced in a pseudo manner.

In the final stage, the central processing unit (3) selects landmarks (such as a song located at the 9th corner, a famous store, a public place, etc.) that are characteristic and are useful for directions among the previously read landscape images.
An image of a location where the image is identified is identified, and only that image is sent to the image processing JIFJ (5). Here, image identification is done in advance using the database fli (4)
When an image is transferred to a computer, the P image processing section (5) performs image area reduction processing on the received image using information added to each image data, and then sends the image to the central processing section J! Part 1 (3
) Insert the reduced landscape image onto the map image at the location that will become the landmark using the @elementary four operations.

Finally, the image processing unit (5) controlled by the central processing unit (3)
) prints and outputs the combined map image on paper using a printer (7).

FIG. 2 shows an example of the composite map obtained in this way.

FIG. 3 shows a flowchart for controlling the stages of the process according to the wishes of the unguided person in the process shown in -1- below.

The first step is to display only the map (6
1k (a), and in the next step the wind lt in the directions
The M image is displayed on the display (6) (b), and finally the map with the image of the landmark location inserted is printed (c), and the process ends.

At the end of each stage, a screen is displayed asking you to choose whether or not to proceed with the next stage. By responding with a 51 tone or a switch, the processing of this device can be controlled at a desired stage.

(}) 5＠Effect of light As is clear from the above explanation, the present invention is based on the importance of directly presenting the surrounding scenery of the actual route to the visual sense of people who are unfamiliar with the area, in route understanding in route guidance. It has a display device that displays a guide map from the current point to destination D, and the display device displays the scenery at each point along the route, and has a device that prints this scenery along with the route. This makes it possible for people whose routes are unclear to more effectively understand their routes.
