Description

  The present invention relates to a system and a device for guiding a vehicle from a current location to a destination when moving by car or walking, and more specifically, a destination guidance system for guiding to a destination by sequentially showing landmarks. , And a destination guide device.

  In recent years, many navigation systems have been used. In this navigation system, a pedestrian navigation system for guiding pedestrians, including a car navigation system for guiding roads of vehicles, has been put into practical use.

  Car navigation systems are used by many people because they can be equipped with necessary equipment such as a GPS receiver for measuring position and a monitor that displays the current position and direction of travel. .

  On the other hand, pedestrian navigation systems are not so popular as compared to car navigation systems, because it is not easy to carry necessary equipment. Moreover, in the case of pedestrians, places that cannot be measured by GPS, such as in buildings and underground malls, may move, and there has been no appropriate positioning technology to replace GPS. Furthermore, although there is a demand for navigation in shopping streets, complex commercial facilities, and event venues, such map data and route data (hereinafter referred to as “map data”) are rarely prepared. In order to put it to practical use, it will be implemented from data preparation, which has also become a barrier to dissemination.

  However, as a result of the remarkable spread of mobile phones in recent years and the dramatic improvement in technology, it has become possible to easily perform positioning using mobile phones even in environments where GPS cannot be used, such as indoors. Indoor positioning technology includes, for example, a positioning method using a wireless LAN access point (such as Place Engine), a positioning method using visible light communication that transmits a fast blinking LED as a signal, and positioning by positioning indoor GPS. Various positioning technologies such as IMES (Indoor Messaging System), positioning method that acquires position information from QR code, visual marker (marker used in ARTToolKit) and RFID tag, positioning method using infrared communication, etc. It can be illustrated. Under such circumstances, navigation systems for pedestrians have been attracting attention, and various services have been provided.

  In the navigation system that has been used conventionally, it is necessary to prepare data such as a map for guiding a moving person to a destination as well as means for positioning the present location such as GPS. In this map data, etc., links such as roads and passages and nodes provided at the connection points of these links are indispensable. For example, in the case of a car navigation system, a road is provided as a link, Need to be maintained as a node. Coordinates are provided for these nodes and links, and the relationship between the nodes and links is set. Based on these geometries (geometric information) and positioning results, the route from the current location to the destination can be guided. is there.

  When navigating pedestrians in shopping streets, complex commercial facilities, and event venues, it was also necessary to maintain data such as maps consisting of links and nodes. FIG. 1 is a plan view showing a store arrangement of a floor for selling food items in a complex commercial facility. When navigating the grocery floor shown in this figure, it is necessary to maintain the entrances and intersections as nodes and between the nodes as links, as well as store information and location information.

  As described above, in order to realize a navigation system, it is necessary to prepare data such as maps including nodes and links, and geometries related to them, and the labor and cost of these investigations and data maintenance will be a heavy burden. I had a problem. In addition, maps and other data have to be updated as roads are newly constructed or improved, and in addition to the initial maintenance burden, updating the data for operation has been a considerable burden. In particular, in places where events are temporarily set up, considering the cost effectiveness, it will be a burden to prepare data such as maps, so it is extremely rare for navigation systems to be constructed in such places. It was.

  Furthermore, many of the conventional navigation systems are guided using nodes (intersections) and links (roads) as clues, such as “turn right at the next intersection” or “go along this road to 1 km”. It was. However, there are actually landmarks such as landmarks and signs that are easier to identify than intersections and roads, and those who use these as clues are easy to understand. However, in the past, there were few guides with such landmarks in consideration of the initial maintenance and update load of data.

  Therefore, Patent Document 1 proposes a route guidance system or the like that prepares data of landmark features and guides the landmark features as a clue.

JP 2010-203946 A

  Patent Document 1 maintains mark feature data, links data and node data, and associates the mark feature data with a link or a node. The intersection (node) is on the right. ”

  As described above, in Patent Document 1, it is necessary to maintain and update data such as nodes and links and their geometry, and it is also necessary to maintain and update landmark feature data. In other words, the burden associated with the maintenance and update of data such as maps was rather reduced, but rather increased.

  In addition, conventional methods for navigating pedestrians in shopping streets, complex commercial facilities, and event venues have different problems. This problem will be described with reference to the example of the pedestrian navigation system on the food floor shown in FIG. When the user P purchases a confectionery, it is necessary to search for a confectionery store on the map displayed on the navigation system. Here, the confectionery store A and the confectionery store B can be found. And if you specify one of the pastry shops, the route to that will be shown. However, the user P can only determine which pastry store suits his taste by actually going to the store. In judging, I would like to refer to the store's reputation, but I can't get such information. Thus, the conventional navigation system for pedestrians has a problem that the user P himself / herself has to search for a destination and lacks reference information for selecting a store. In addition, it is possible to prepare detailed information of the store from the initial data stage and display it, but in this case it is generally information on the store side and is not objective and new information (for example, recently used person) Is not enough as reference information.

  An object of the present invention is to solve the problems of the prior art, and to provide an intuitive and easy-to-understand destination guidance system that uses a mark as a clue without maintaining and updating nodes and links and their geometries, and an object. It is to provide a ground guidance device.

[Embodiment]
An embodiment of a destination guidance system and a destination guidance device according to the present invention will be described below with reference to the drawings.

(Overview)
The destination guidance system and destination guidance device of the present invention guide the current location to the destination, and can be used by any means of movement such as movement by car or movement by walking. In addition, it can be used in any place, such as indoors, outdoors, or above ground or underground. Here, for the sake of convenience, a case will be described as an example where guidance is provided to a target store on a floor (hereinafter, simply referred to as “food floor”) in the complex commercial facility shown in FIG.

  As shown in FIG. 1, the user P is now standing at the entrance of the grocery floor and going to the intended snack shop C. Therefore, the portable terminal 1 (FIG. 3) is held, and a snack shop C, which is the destination, is input thereto. Then, a mark on the route from the current position to the snack shop C is displayed on a display function (display means) provided in the portable terminal 1. At this time, since the marks are displayed in the order of passing from the current position to the snack shop C, the user P can reach the snack shop C by following the landmarks. In addition, although the passage is provided in FIG. 1, in this invention, the installation and space (so-called route) provided for traffic, such as a road and a passage, are not necessarily required. In the prior art, a route is required. For example, in Patent Document 1, a road (link) corresponding to the route is required, and geometry data of links and nodes is also required. The fact that this route is not necessary is one of the technical features of the present invention, and even in places where there is no route, for example, a place opened like a park, it is possible to guide fountains and objects as landmarks. is there.

(Mark)
The mark is visible, and it is desirable to make it more conspicuous if possible. In addition, since the next mark is guided as a clue when the mark is reached, the mark is provided at a place where other marks can be seen (visible) when standing near the mark. The number of marks that can be seen from the mark (hereinafter referred to as “visible marks”) is sufficient, but of course, it may be provided in a place where two or more marks can be seen. Further, if it can be seen from the mark, it can be selected as a mark that can be seen, and it is not always necessary to see the mark from the mark that can be seen, that is, it is not necessary that both can see each other.

  FIG. 2 is a model diagram for explaining visibility between the landmarks. In the case of this figure, when the user stands on the mark Ma, the mark Mb can be seen, so that the mark Mb can be seen. Similarly, the mark Mc and the mark Md are marked on the mark Mb, the mark Mf is marked on the mark Mc, and the mark Me is marked on the mark Me. Md and the mark Mf are visibility marks. On the other hand, when standing at the mark Ma, the mark Mc cannot be seen due to the influence of an obstacle or the like, and therefore, it cannot be seen. Therefore, in FIG. 2, for example, when the user P is at the mark Ma, the user P can start from here and guide to the destination (in this case, the mark Mf) in the order of the mark Mb → the mark Mc → the mark Mf.

  As many landmarks as necessary are set within the range targeted by the destination guidance system and destination guidance device of the present invention, but it is not always necessary to construct a landmark as a new structure. , What has already been installed can be set as a landmark. FIG. 3 is an explanatory diagram showing a situation in which the user P stands at the escalator exit M4, which is a landmark, and uses the clock M5, which is the landmark, and FIG. 4 is a store signboard M6, where the user P is the landmark. It is explanatory drawing which shows the condition which arrived at the snack shop C although it found the destination. M4 to M6 correspond to those in FIG.

  In this way, the mark covers various things such as the watch M5 that is easy to identify as a point, those that can identify the general point such as the exit M4 of the escalator, and those that can be easily installed and removed like the store signboard M6. sell. Of course, in some cases, a new structure or the like can be constructed and set as a landmark. Further, the mark is not necessarily provided at a branch point on the route such as an intersection, and may be provided at a long straight intermediate point.

(Market information)
In the destination guidance system and destination guidance device of the present invention, landmark information is prepared in advance. The mark information includes information related to the mark and information on a visible mark that can be seen when standing near the mark. For example, in the case of FIG. 3, the mark information of the exit M4 includes information that the mark is the exit of the escalator and that the visibility mark is the clock M5.

  The “information on the mark” included in the mark information may be text-based information indicating the characteristic of the mark (hereinafter referred to as “marker attribute information”), or image information or video information (hereinafter referred to as “marker attribute information”). "Marker image information") or a combination of landmark attribute information and landmark image information. In addition, mark attribute information can be divided into representative contents (name and outline) and detailed contents (clock color, store appearance, etc.), and include multiple images as mark image information. You can also. Further, as described above, the “viewable mark information” included in the mark information is not limited to one but may be two or more.

  The mark information can also include coordinates. In this case, it can be a three-dimensional coordinate (X, Y, Z) provided with a coordinate of height, or can be a plane coordinate (X, Y).

  In implementing the destination guidance system and destination guidance device of the present invention, usually, a large number of landmarks are set, that is, a large number of landmark information is prepared. The mark information is stored in the mark storage means (mark storage function). At this time, it is preferable to construct a database of landmark information. For example, if the landmark information is composed of an identification number (ID), character information, image information, and coordinate information, text search and position search are possible.

(Auxiliary mark)
The mark is visible (if more prominent if possible), and is provided at a place where other marks can be seen when standing near the mark. On the other hand, some are visible, and other landmarks cannot be seen from the vicinity of the ground, but others are visible. Such a thing can be maintained as an auxiliary landmark. For example, when the designated destination cannot be seen from any of the landmarks, the auxiliary landmark can relay the landmark and the destination, which is suitable for smoothly guiding the user P to the destination. The auxiliary mark information is maintained in the same manner as the mark information except for “visible mark information”, and is stored in the mark storage means (mark storage function). In addition, although it does not stop there, the auxiliary landmark information can also be prepared using an auxiliary landmark that can be seen from any position in the vicinity (for example, Tokyo Tower or Sky Tree).

(Own position)
The self-position here is a place where the user P exists (is standing). When using the destination guidance system and destination guidance device of the present invention, the user's own position (that is, the start point) at the start time is input, but the user P moves according to the guidance, Since it changes, your position is dynamic information, not necessarily the starting point.

  The own position is input by own position input means (own position acquisition function). The own position at this time can be input as coordinates, or can be input by designating mark information near the own position. When specifying landmark information in the vicinity of its own position, a landmark in the vicinity is designated by selecting from the DB of the landmark information by text search or position search, or by selecting from a list display of landmark information. can do.

  When inputting as coordinates, it is necessary to measure (position) the own position by positioning means. As a positioning method in the present invention, various conventionally used methods can be used. For example, GPS can be cited as a typical example when positioning outdoors, and when positioning by GPS is difficult, such as indoors, a positioning method using a wireless LAN access point (such as Place Engine), LED flashes rapidly. Positioning method using visible light communication to transmit as a signal, IMES (Indoor Messaging System) positioning by positioning GPS indoors, QR code and visual marker (marker used in ARTToolKit), RFID tag, etc. Various methods such as a positioning method for acquiring position information and a positioning method using infrared communication can be exemplified. Here, the coordinates acquired by positioning can be three-dimensional coordinates (X, Y, Z) or plane coordinates (X, Y).

  In order to input the own position coordinates measured by the positioning means, the coordinate value can be directly input by the own position input means, but the own position acquisition having both the positioning means and the means for automatically fetching the coordinate values is possible. It is desirable to provide means (function self-location acquisition function). By providing the own position acquisition means (functional own position acquisition function), it is possible to omit the trouble of inputting the coordinate location by the user P and to prevent a transcription error (input error).

(Destination)
When using the destination guidance system or destination guidance device of the present invention, the user P designates the destination by destination designation means (destination designation function). The designation of the destination is performed by selecting a desired one from the destination information prepared in advance. For example, a destination can be represented on a map and a desired destination can be selected from the map. Alternatively, a destination information database is constructed, and a desired destination can be selected from this DB by text search or position search. In addition, a list of destination information can be simply displayed and a desired destination can be selected from this display.

  As with the landmarks, the number of destinations is set within the range targeted by the present invention, as many as necessary, but it is not always necessary to construct a new destination as a structure, and it has already been installed. What is present (for example, a store) can be set as the destination. Further, as will be described later, the landmark can also be used as the destination.

  The destination information includes information related to the destination. The “information about the destination” may be text-based information indicating the characteristics of the destination (hereinafter referred to as “destination attribute information”), or image information or video information (hereinafter referred to as “information about the destination”). "Destination image information") or a combination of destination attribute information and destination image information. In addition, destination attribute information can be divided into representative contents (name and outline) and detailed contents (clock color, store appearance, etc.), and a plurality of images as destination image information. Can also be included.

  The destination information can also include coordinates as destination position information. In this case, the coordinates can be three-dimensional coordinates (X, Y, Z) or plane coordinates (X, Y). In this case, as described above, the destination can be represented on the map, and a desired destination can be selected from the map.

  A plurality of destination information is stored in the destination storage means (destination storage function). At this time, it is preferable to construct a database of destination information. For example, if the destination information is composed of an identification number (ID), character information, image information, and coordinate information, text search and position search can be performed. In addition, since the destination may be a store, various information such as the type of store (clothing store, food, etc.), subdivision of the type (Japanese food, Western food, etc.), business days and business hours, etc. When it is provided, it becomes easier to search, and it becomes possible to select various destinations such as a user P who feels attractive and wants to visit a destination different from the destination originally planned.

  In addition, by providing the own position acquisition means (functional own position acquisition function), it is possible to measure the own position periodically while the user P is moving. Based on the measurement results (coordinates), destination information around the user's own location can be displayed on a display function or display means (hereinafter collectively referred to as “monitor”). The location (for example, a store) can be grasped, and the same type of store can be found at a location closer to the initially planned store. Or it becomes possible to display the advertisement regarding the store around the own position, that is, a position-linked advertisement can also be realized.

  The destination information can be the same content as the landmark information except for “Visible marker information”. Therefore, only the landmark information is prepared and stored in the landmark storage means (marker storage function). A destination can also be designated from the mark information (or auxiliary mark information). Alternatively, the landmark information (auxiliary landmark information) and the destination information (or each DB) are prepared separately, but both of them are the landmark storage means (the landmark storage function) or the destination storage means (the destination storage function). Either one can be stored.

  Of the destination information, the destination attribute information and the destination image information may be appropriately updated by destination information input means (destination information input function). The input authority of this destination information input means (destination information input function) can be designed freely, it can be given only to the system administrator, or it can be input to any input person via the Internet line etc. Can also be given. Giving the system administrator input authority is preferable because, for example, the store side can easily provide advertisements. Alternatively, if an input authority is given to an arbitrary input person and the user can input freely using, for example, a communication tool (for example, Twitter, etc.), the store user can input its reputation and the like, so various information can be used for specifying the destination. Increases and becomes suitable.

(Market extraction)
When the user's own position is input (or acquired) and the destination is specified, the landmark to be advanced is extracted from the landmark information by the landmark extraction means (marker extraction function). The extraction of the mark is roughly divided into a case where the coordinates are not used and a case where the marks are based on the coordinates. Hereinafter, each case will be described individually.

1. When not using coordinates The input of the own position is performed by the user P selecting, for example, the nearest mark from the mark information and designating the mark as the own position. The destination is designated by selecting a desired one by searching or the like from the prepared destination information and designating it as the destination.

  Based on the “viewable mark information” included in the mark information of the own position, the “mark to be advanced” as the next mark is selected from the mark information stored in the mark storage means (mark mark storage function). Extract. Based on the “viewable mark information” included in the “mark to be advanced”, a “mark to be advanced” is further extracted. This process is repeated until the destination is reached. The determination of arrival at the destination (that is, determination of the end of processing) can be made until the mark is extracted as “mark to be advanced” when the mark is designated as the destination. In addition, when a landmark is not designated as the destination, the destination information and the landmark information are associated in advance, and the above processing is performed until the landmark associated with the designated destination is extracted as a “mark to go” It can also be made. The order of the “marks to proceed” extracted in this way is the route from the first location to the destination.

  When a plurality of “marks to be advanced” are selected, “branch marks to be advanced” are sequentially extracted thereafter, and as a result, combinations (that is, routes) of a plurality of “marks to be advanced” are extracted. In this case, all routes may be presented to the user P, or the distance between the landmarks is prepared in advance, and only the route with the shortest distance is presented to the user P. You can also.

  When a plurality of “marks to go” are selected, the shortest route (route) can be estimated without preparing the marks, the coordinates of the destination, or the distance between the marks in advance. This will be specifically described with reference to FIG. First, a route from the mark designated as the own position (mark A in FIG. 5) to the destination (mark Z in FIG. 5) is calculated (primary analysis). At the same time, a route from the destination (mark Z) to the mark (mark A) set as the own position is also calculated (secondary analysis). As shown in FIG. 5, in the primary analysis (the route from the own position to the destination) and the secondary analysis (the reverse path from the destination to the own position), if there are multiple options for each mark, the route is in an amoeba shape. As a result, various routes are required. When a plurality of routes (forward route) obtained by the primary analysis and a plurality of routes (reverse route) obtained by the secondary analysis are collated, a case having a common mark (mark N in FIG. 5) for each route ( A combination of forward and reverse). At this time, start the mark (mark A) that is your position, and use the common mark (mark N) to reach the destination (mark Z) as the shortest path (course) Can do.

  The “marks to proceed” are displayed on the monitor in order from the first location to the destination. In other words, taking FIG. 1 as an example, it is displayed on the monitor in the order of M1, M2, M3, M4, M5, and M6. At this time, M1 to M6 may always be displayed in series, or every time the “mark to be advanced” (for example, M2) is reached, that fact is input, thereby the next “mark to be advanced” (for example, M3). The monitor display can also be changed. Alternatively, by always displaying a series of M1 to M6 and inputting that the “mark to be advanced” (for example, M2) has been reached, the next “mark to be advanced” (for example, M3) is highlighted ( Highlight).

  If the positional relationship between the mark and the preceding and following marks is prepared in advance, by entering that the mark has been reached, an arrow or character information indicating the direction of the next “mark to proceed” (such as a right turn or Left turn, diagonally forward right, 11 o'clock direction, etc.) can be displayed on the monitor. Further, if the distance between the mark is prepared in advance, the distance to the next “mark to be advanced” can be displayed on the monitor by inputting that the mark has been reached.

  The route in the order of the “mark to go” extracted based on the information on the own position and the destination can be processed at the timing when the information on the own position and the destination is inputted, or various kinds of own positions It can also be prepared in advance from a combination of (mark) and destination. However, when the number of pieces of mark information is large, it is desirable to perform arithmetic processing at the timing when the information is input.

2. When Based on Coordinates The coordinates of the own position are acquired by the own position acquisition means (functional own position acquisition function) having both the positioning means and the coordinate capturing means. This series of processing from positioning to coordinate acquisition can be performed each time by the operation of the user P, or can be performed periodically and automatically.

  A landmark that is close to the coordinates of its own position is retrieved by the landmark extraction means (mark extraction function). Therefore, in this case, the mark information includes coordinates. Then, based on the “viewable mark information” included in the searched mark information, the “mark to be advanced” that is the next mark from the mark information stored in the mark storage means (mark mark storage function). To extract. Based on the “viewable mark information” included in the “mark to be advanced”, a “mark to be advanced” is further extracted. This process is repeated until the destination is reached. The determination of arrival at the destination (that is, determination of the end of processing) can be made until the mark is extracted as “mark to be advanced” when the mark is designated as the destination. Further, when a landmark is not designated as the destination, the above-described processing can be performed until a landmark within a predetermined range from the destination is extracted as a “mark to be advanced”. The predetermined range from the destination is a distance (radius) provided as a threshold value in advance. Therefore, in this case, coordinates are included in the destination information. The order of the “marks to proceed” extracted in this way is the route from the first location to the destination.

  When a plurality of “marks to be advanced” are selected, “branch marks to be advanced” are sequentially extracted thereafter, and as a result, combinations (that is, routes) of a plurality of “marks to be advanced” are extracted. In this case, all routes may be presented to the user P, or the distance between the landmarks may be calculated to present only an appropriate route to the user P. The appropriate route can be appropriately designed such as a route having the shortest distance or up to five routes counted from a short distance.

  The “marks to proceed” are displayed on the monitor in order from the first location to the destination. In other words, taking FIG. 1 as an example, it is displayed on the monitor in the order of M1, M2, M3, M4, M5, and M6. At this time, M1 to M6 may always be displayed in series. Alternatively, the positioning is performed periodically and automatically, and it is automatically determined by the mark extraction means (mark mark extraction function) that the user P has reached the “mark to be advanced” (for example, M2). It is also possible to change the monitor display to “a mark to proceed” (for example, M3). Further, after always displaying M1 to M6 in a series, the mark extraction means (markmark extraction function) automatically determines that the mark “move to proceed” (for example, M2) has been reached. It is also possible to highlight (highlight) the “mark to go” (for example, M3). When the mark extraction means (mark extraction function) determines that the user P has reached the “mark to be advanced”, the coordinates of the own position acquired by automatic positioning are within a predetermined range from the “mark to be advanced”. Judgment can be made based on whether it is within or not. The predetermined range from the mark is a distance (radius) provided in advance as a threshold value.

  When it is determined by the mark extraction means (mark extraction function) that the user P has reached the “mark to be advanced”, various guidance displays are displayed on the monitor based on the coordinates of the mark and the “mark to be advanced”. Can be made. That is, at the timing when the user P reaches the “mark to go”, the distance to the next “mark to go” can be displayed on the monitor. If the portable terminal 1 is provided with a means (function) capable of acquiring an orientation such as an electronic compass, an arrow indicating the direction of the next “mark to go” or character information (right turn, left turn, diagonally forward right, 11 The time direction, etc.) can also be displayed on the monitor when the user P reaches the “mark to go”.
