BACKGROUND OF THE INVENTION
  The present invention provides, on a predetermined premises, a premises guidance device for guiding a route from a first point as a starting point to a second point as a destination point,Program and campus guidance methodAbout.
[0002]
[Prior art]
Various methods have conventionally been considered and put into practical use as methods for accessing target information. In particular, with the development of information processing technology in recent years, technology for searching for and accessing target information has made dramatic progress.
[0003]
As an example, the applicant of this application has put a book search system into practical use and commercialized it as remedy (trade name). This book search system has various functions, but one of them is to search for books (including magazines, papers, etc.) based on various keywords, and to use information about books as search results. Provided to the user of the user terminal.
[0004]
[Problems to be solved by the invention]
Taking a book search as an example, a person who searches for a book and accesses information about the desired book will usually want to access the book itself. Therefore, it is conceivable to include information on the location of the book in the book search result. For example, in the case of a library, information on a place where the book is stored is provided, and in the case of a bookstore, information on a sales floor in the bookstore where the book is sold is provided.
[0005]
However, even if you provide information about the location in the library where the book is stored and the sales floor in the bookstore where the book is sold, those who are unfamiliar with the library or bookstore have access to the book. It's not easy. For this reason, an effective method for supporting access to the retrieved books is desired.
[0006]
In addition, as a tool for route guidance to a target place, conventionally, a navigation system represented by a car navigation system has been proposed (for example, Japanese Patent Laid-Open Nos. 9-119845 and 10-318773, JP-A-11-94571, etc.) are widely used. However, such a navigation system cannot be applied as it is as a tool for supporting access to searched books.
[0007]
An object of the present invention is to provide an effective technique for supporting access to a search object such as a searched book.

[0055]
The book search system 401 has a hardware configuration similar to that of the server 101, and provides a book search function to the client 201 that is accessing the book search system 401. That is, the book search system 401 is also a computer including a microcomputer including a CPU and a memory, and interprets and executes software for book search. The software for book search is an external program linked by a CGI program executed on the book search system 401, and performs processing in response to a request from the browser software of the client 201.
[0056]
Here, as illustrated in FIG. 1, the client 201 can search for a book by accessing the book search system 401. The book search is performed, for example, when the book search system 401 provides a book search screen to the client 201 and the client 201 inputs a keyword to the book search screen by the input device 221. That is, the book search software executed on the book search system 401 searches a book database (not shown) according to the keyword input by the client 201 and provides the corresponding book information to the client 201. The book search result screen 1001 illustrated in FIG. 1 provides the user with arrangement information 1011 in which the searched book is arranged.

[0057]
FIG. 3 is a flowchart showing the flow of the on-site guidance process. FIG. 4 is a schematic diagram illustrating an example of a guidance screen. FIG. 5 is a schematic diagram illustrating an example of a panoramic image that is a peripheral image of a node included in the attribute screen in the guidance screen. FIG. 6 is a schematic diagram showing an example of a panoramic image transformed into a donut shape that is a peripheral image of a node included in the attribute screen in the guidance screen. Hereinafter, the flow of the on-site guidance process will be described with reference to FIG.
[0058]
When a hyperlink 1003 in the placement information 1002 displayed on the book search result screen 1001 is clicked, in addition to a command to start the campus guidance processing program, the place where the searched book is placed, for example, the number of floors of the library Along with the information on the library, information on the first point serving as the starting point and the second point serving as the destination point on the campus of the corresponding floor of the library is transmitted from the book search system 401 to the server 101. Thereby, in the server 101, information related to the number of floors of the library and information related to the first point serving as the starting point and the second point serving as the arrival point on the premises of the corresponding floor of the library are input (step S101). ). Here, a means (step) for receiving inputs of a first point serving as a starting point and a second point serving as a destination point on a predetermined campus is executed.
[0059]
Next, in the server 101, a combination of a node and a route that is the shortest route from the first point (A) to the second point (B) is calculated by the route search software (step S102). Such processing by the route search software is executed by a known calculation method for calculating a combination of a node and a route that is the shortest route from the starting point to the destination point. As such a known calculation method, for example, “Iwanami Shoten, Kiyoshi Ishihata, Software Science Volume 3“ Algorithms and Data Structures ”, Chapter 4“ Graph Algorithms ”, Section 5“ Shortest Path Problem ”(b ) A simple method for realizing the Dijkstra algorithm ”. Here, a means (step) for calculating a route composed of a node and a route from the first point to the second point based on the input first point and second point is executed. .
[0060]
Next, it is determined whether or not there is a route as a result of the calculation in step S102 (step S103). If there is no route, it is possible to browse without a route on the client 201 (step S104), and if there is a plan view of the corresponding floor of the library. It is possible to browse in 201 (step S105). In this case, the plan view of the corresponding floor of the library is an example of a drawing representing the campus, and the drawing representing the campus is not limited to the plan view, but various drawings such as a three-dimensional view and a bird's eye view. Can be adopted.
[0061]
As a result of the processing in step S105, a guidance screen 2001 is displayed on the display device 211 of the client 201. This guidance screen 2001 is composed of a map screen 2101 and an attribute screen 2201 as illustrated in FIGS. When the process of step S105 is completed, only the map screen 2101 is displayed in the guidance screen 2001.
[0062]
Next, in step S106, an attribute screen and an attribute information program are created. In this way, in step S105 and step S106, a database (hard disk {circle around (2)} 131) that stores and saves image information necessary for generating a drawing representing the premises and attribute information relating to the nodes and routes is retrieved, and the drawings representing the premises. Information for generating a guidance screen 2001 combining a map screen 2101 for displaying a calculated route and an attribute screen 2201 for displaying attribute information of nodes and routes constituting the calculated route in order of the route. Collecting means (steps) are executed.
[0063]
In step S106, the created attribute information program is transmitted to the client 201. As a result, the client 201 can execute the attribute information program.
[0064]
Next, the server 101 allows the client 201 to browse the attribute screen created in step S106 (step S107). As a result, the attribute screen 2201 illustrated in FIGS. 1 and 4 can be displayed on the client 201.
[0065]
At this time, the server 101 transmits the calculation result in step S102 to the client 201. Therefore, the client 201 interprets and executes the attribute information program transmitted from the server 101 in step S106, so that the node and route corresponding to the shortest path are displayed on the map screen 2101 according to the calculated result in step S102. The display can be browsed (step S108). In the flowchart of FIG. 3, the process of step S108 is shown in parentheses because the process of step S108 is interpreted and executed by the microcomputer included in the client 201. As a result, as illustrated in FIGS. 1 and 4, the client 201 includes the nodes 2111 illustrated as “502”, “506”, “507”, and “509” on the map screen 2101, and those The route 2121 connecting the nodes 2111 can be displayed. In the map screen 2101 illustrated in FIG. 4, the node 2111 displayed as “502” is the first point as the starting point, and the node 2111 displayed as “509” is the second point as the destination. It is a point.
[0066]
As described above, the server 101 executes processing for enabling browsing of certain information by the client 201 as in steps S105, S107, and S108. Here, a means (step) for enabling the user terminal (client 201) to browse the guidance screen 2001 based on the collected information is executed.
[0067]
Thereafter, the server 101 waits for user input (step S109).
[0068]
Here, the guidance screen 2001 including the attribute screen 2201 will be described.
[0069]
First, the attribute screen 2201 has various objects that can be specified by the client 201 browsing the guide screen 2001. In this case, the designation on the client 201 is, for example, by a click operation with a pointing device included in the input device 221. When such an object is designated by the client 201, a change occurs in the guidance screen 2001 that is being browsed by the display device 211. This is a function obtained by interpreting and executing on the client 201 the attribute information program transmitted from the server 101 to the client 201 in step S106 in the flowchart shown in FIG.
[0070]
Next, the attribute screen 2201 has a brief description 2211 explaining the guidance route guided by the guidance screen 2001 at the beginning of the attribute screen 2201. In FIG. 4, “shortest path from 502 to 509” is shown as the short description 2211. 502 and 509 mean the node 2111.
[0071]
Below the description of such a guide route, an object 2221 “return to selection screen” is shown. When the object 2221 is clicked on the client 201, the attribute information program transmitted from the server 101 to the client 201 in step S106 is interpreted and executed by the client 201, and the client 201 returns the screen display to the selection screen. This selection screen is, for example, the book search result screen 1001 illustrated in FIG.
[0072]
In the guidance screen 2001, a check box 2231 as a route blinking designation object with an explanation of “all nodes and routes blinking display” is displayed below the object 2221 “return to selection screen”. . When this check box 2231 is clicked, the attribute information program transmitted from the server 101 to the client 201 in step S106 is interpreted and executed by the client 201, and displayed on the map screen 2101 of the client 201 by the processing in step S108 of the server 101. Nodes 2111 and the route 2121 connecting these nodes 2111 are displayed in a blinking manner. As a result, the node 2111 and the route 2121 are conspicuous and can be easily visually recognized.
[0073]
In addition, in the guidance screen 2001, a route actual captured video with a description “view all route videos continuously” is displayed below a check box 2231 with a description “all nodes, blinking display of route”. A designated object 2241 is displayed. When this route actual shot video designation object 2241 is clicked, the attribute information program transmitted from the server 101 to the client 201 in step S106 is interpreted and executed by the client 201. Actual captured images (moving images) of all the routes up to 509 are reproduced. In this case, even if such actual captured video is transmitted in advance from the server 101 to the client 201 together with the attribute information program in step S106, the actual path captured with the description of “viewing all path video continuously” is attached. The server 101 may be notified that the video designation object 2241 has been clicked, and the server 101 may send it to the client 201 in response to this, or any known method for executing the same type of processing may be used.
[0074]
Next, on the attribute screen 2201, attribute information on the node 2111 that constitutes the guide route in the map screen 2101 under the actual route shooting image designation object 2241 with the description “view all the route images continuously”. 2251 and attribute information 2261 related to the route 2121 are displayed in the order of the route. These attribute information 2251 and 2261 are shown as “departure node 502”, “from route 502 to 506”, “node 506”, “from route 506 to 507” on the attribute screen 2201 illustrated in FIG. Has been.
[0075]
In the attribute information 2251 related to the node 2111, the identification number 2252 of the node 2111 is indicated as a node ID, and a spot name 2253 and a spot summary 2254 are indicated. In the attribute screen 2201 shown in FIG. 4, “502” is shown as the identification number 2252 of the node 2111, “5th floor hall” is shown as the spot name 2253, “near the main building elevator” is shown as the spot summary 2254, and the identification number 2252 of the node 2111 is shown. "506", "5th floor new library nature book back number (1)" as the spot name 2253, and "5th floor new library nature book back number (1)" as the spot outline 2254, respectively.
[0076]
Further, the attribute information 2251 related to the node 2111 includes a peripheral image of the node 2111. In this embodiment, a panoramic image 2255 around the node 2111 and an image 2256 obtained by transforming such a panoramic image 2255 into a donut shape are displayed as the peripheral image of the node 2111. The panorama image 2255 may be a 360-degree image or a panorama image at a narrower angle. In addition, the panorama image 2255 and the image 2256 deformed into a donut shape are configured by actual captured video as an example. You may use as the image 2256 deform | transformed into the donut shape. In addition, the peripheral image of the node 2111 is not necessarily the panoramic image 2255 and the image 2256 deformed into a donut shape.
[0077]
Here, FIG. 5 illustrates a panoramic image 2255 as the attribute information 2251 of the node 2111 whose identification number 2252 is “506”, and FIG. 6 illustrates an image 2256 obtained by transforming such a panoramic image 2255 into a donut shape. is doing.
[0078]
Further, the panorama image 2255 and the image 2256 transformed into a donut shape itself constitute an object, and when clicked, the attribute information program transmitted from the server 101 to the client 201 in step S106 is interpreted and executed by the client 201. Then, the clicked panorama image 2255 or an image 2256 deformed into a donut shape is enlarged and displayed. FIG. 1 illustrates a state where an image 2256 obtained by transforming the panoramic image 2255 into a donut shape is clicked to become an enlarged image.
[0079]
In addition, in the attribute screen 2201 related to the node 2111, a check box 2257 as a node blinking designation object with an explanation “node blinking display” is displayed. When this check box 2257 is clicked, the attribute information program transmitted from the server 101 to the client 201 in step S106 is interpreted and executed by the client 201, and displayed in the map screen 2101 of the client 201 by the processing in step S108. Node 2111 is displayed blinking. For example, when the check box 2257 in the attribute screen 2201 related to the node 2111 whose identification number 2252 is “502” is clicked, the node 2111 “502” displayed in the map screen 2101 is blinked. As a result, the target node 2111 is conspicuous and easily visible.
[0080]
Next, in the attribute information 2261 regarding the route 2121, an identification number 2262 of the route 2121 is indicated as a node ID, and a route name 2263 as a point name and a point summary 2264 are indicated. In the attribute screen 2201 shown in FIG. 4, “5026_0” is identified as the identification number 2262 of the route 2121 from 502 to 506, “5th floor new library natural book back number (1) direction” as the location name 2263, and “5” as the location overview 2264. The route from the main floor hall to the 5th floor new library nature book back number (1) "is shown," 5067_0 "as the identification number 2262 of the route 2121 from 506 to 507, and" 5th floor new building natural book "as the spot name 2263 "Back number (2) direction", as the point outline 2264, "5th floor new library natural library back number (2) from 5th floor new library natural library back number (2)" is shown respectively.
[0081]
The attribute information 2261 relating to the route 2121 includes a peripheral image 2265 at the start point of the route 2121 and a peripheral image 2266 at the end point. These peripheral images 2265 and 2266 are configured by actual captured video as an example. However, in practice, animation images or the like may be used as the peripheral images 2265 and 2266 instead of the actual captured video.
[0082]
Further, these peripheral images 2265 and 2266 themselves constitute an object, and when clicked, the attribute information program transmitted from the server 101 to the client 201 in step S106 is interpreted and executed by the client 201 and clicked. The peripheral images 2265 and 2266 are enlarged and displayed. FIG. 1 exemplifies a state in which the peripheral image 2266 at the end point of the route 2121 with the identification number “5026_0” is clicked to become an enlarged image.
[0083]
The attribute information 2261 relating to the route 2121 includes a symbol 2267 indicating a traveling direction and a change in direction in the route 2121 located between the peripheral image 2265 at the start point of the route 2121 and the peripheral image 2266 at the end point. A required time 2268 corresponding to the symbol 2267 is displayed. As an example of such a symbol 2267 and the required time 2268, a route 2121 with an identification number “5026_0” from 502 to 507 is taken as an example, straight travel 4.5 seconds, left turn 2.5 seconds, straight travel 17.9 seconds.
[0084]
Here, an example is shown in which the required time 2268 of each symbol 2267 is displayed in correspondence with the symbol 2267 indicating the traveling direction and the direction change in the route 2121. However, instead of the required time 2268, the required number of walks is displayed. Anyway.
[0085]
In the attribute screen 2201 related to the route 2121, a check box 2269 is displayed as a route blinking designation object with an explanation of “route blinking display”. When this check box 2269 is clicked, the attribute information program transmitted from the server 101 to the client 201 in step S106 is interpreted and executed by the client 201, and the corresponding information displayed in the map screen 2101 of the client 201 by the processing in step S108. The route 2121 is displayed blinking. For example, when the check box 2269 in the attribute screen 2201 related to the route 2121 with the identification number 2262 of “5026_0” is clicked, the routes 2121 from 502 to 506 displayed in the map screen 2101 are blinked. As a result, the target route 2121 is conspicuous and easily visible.
[0086]
Also, in the attribute screen 2201 related to the route 2121, a route actual captured video designation object 2270 with an explanation “view route video” is displayed. When this route actual captured video designation object 2270 is clicked, the attribute information program transmitted from the server 101 to the client 201 in step S106 is interpreted and executed by the client 201, and the route 2121 corresponding to the attribute screen 2201 is reached from the start point to the end point. The actual captured video (movie) is played back. In this case, even if such actual captured video is transmitted in advance from the server 101 to the client 201 together with the attribute information program in step S106, the route actual captured video designation object 2270 with the description “view root video” is attached. May be notified to the server 101, and the server 101 may send it to the client 201 in response to this, or any known method for executing the same kind of processing may be used.
[0087]
Further, the attribute information program that is interpreted and executed by the client 201 is clicked on the route actual captured video designation object 2270 with the description of “view root video” and the corresponding end point from the start point of the route 2121 in the attribute screen 2201. The corresponding route 2121 displayed in the map screen 2101 is displayed in an animation in accordance with the progress of the actual captured video (moving image) that is reached. As an example of the animation display, for example, a part of the color of the corresponding route 2121 displayed in the map screen 2101 may be changed in accordance with the progress of reproduction of the actual captured video (moving image) of the route 2121. It is possible to employ a method of displaying a part of the corresponding route 2121 in a blinking manner.

<Second Embodiment>
A second embodiment of the present invention will be described with reference to FIGS. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is also omitted. Accordingly, reference is also made to FIGS. 1 to 6 used to describe the first embodiment as appropriate.
[0090]
The present embodiment relates to details of processing in the case where a route actual captured image designation object 2241 with an explanation of “viewing all route images continuously” is clicked on the guidance screen 2001 shown in FIG. As described above, in the guidance screen 2001 shown in FIG. 4, below the check box 2231 with the description of “all nodes, blinking display of route”, there is an explanation of “viewing all route images continuously”. Attached route actual shooting video designation object 2241 is displayed. When this route actual captured video designation object 2241 is clicked, the attribute information program transmitted from the server 101 to the client 201 in step S106 is interpreted and executed by the client 201, and actual captured images (moving images) of all routes are displayed in the guidance screen 2001. Played. In this case, even if such actual captured video is transmitted in advance from the server 101 to the client 201 together with the attribute information program in step S106, the actual path captured with the description of “viewing all path video continuously” is attached. The server 101 may be notified that the video designation object 2241 has been clicked, and the server 101 may send it to the client 201 in response to this, or any known method for executing the same type of processing may be used.
[0091]
In addition, here, an example is shown in which an actually captured video is used as the actual captured video. However, the actual captured video does not have to be a real captured video, and may be, for example, a graphics image or an animation image. . In other words, any video can be used as long as the video can be easily recognized by the user, whether it is an actually captured video or a created virtual video. In this sense, in the guidance screen 2001 shown in FIG. 4, the actual route shooting image designation object 2241 with the description “view all the route images continuously” can also be referred to as a route image designation object 2241. . Therefore, in the present embodiment, the object referred to as the path actual captured video designation object 2241 in the first embodiment is referred to as the path video designation object 2241.
[0092]
FIG. 7 is a schematic diagram illustrating an example of the map screen 2101. In this map screen 2101, all nodes 2111 and routes 2121 set in the server 11 are shown. In the route, a first point as a starting point and a second point as a destination point are selected from a plurality of preset nodes 2111 (indicated by 501 to 509 in FIG. 7). . As the guide route from the first point to the second point, the shortest route is selected from a plurality of preset routes 2121 connecting the nodes 2111. For example, when the first point is the node 2111 “502” and the second point is the node 2111 “508”, the route is “502” → “506”, “506” → “508”. As described above, the algorithm for obtaining such a route is executed by a known calculation method for calculating a combination of the node 2111 and the route 2121 that are the shortest route from the starting point to the destination point.
[0093]
Here, when such a route is provided as a video on the guidance screen 2001, if all the routes from all the nodes 2111 to all the nodes 2111 are photographed, the amount of photographing becomes enormous and the amount of data becomes enormous. . Therefore, a method may be considered in which a moving image is captured for each route 2121 connecting the nodes 2111 and the moving images divided for each route 2121 are combined and provided to the user. In the case of the above-described example, the image of the route 2121 from “502” to “506” and the image of the route 2121 from “506” to “508” are combined, and “502” is combined. → Video that reaches “508” is provided to the user. At this time, Real Media (registered trademark), Windows Media (registered trademark), or the like is used as a streaming video format. In addition, as a means for providing and combining images, for example, the description illustrated in FIG. 8 is created using SMIL, for example, a route image list is created, and the description is described in Real Player (registered trademark) or the like. By reading a route video list as a file, the combined video can be provided to the user as a streaming video via the network 301.
[0094]
When images are combined in this way, it is highly desirable for guiding the routes that the directions of the images match in the portion where the images are combined. In the case of the above example, the shooting direction at the end of the video of the route 2121 from “502” to “506” and the shooting direction at the start of the video of the route 2121 from “506” to “508” Should be consistent. In this way, the user can view a continuous video from “502” to “508” via “506”.
[0095]
However, the node 2111 “506” is a starting point of the route 2121 to the node 2111 “507” in addition to the route 2121 to the node 2111 “508”. In this case, as is apparent from FIG. 7, a route 2121 from the node 2111 “506” to the node 2111 “507” and a route 2121 from the node 2111 “506” to the node 2111 “508” Are in different directions. Therefore, in such a case, the start of the image of the route 2121 reaching “506” → “508” with respect to the orientation at the end of the image of the route 2121 reaching “502” → “506”. Therefore, it is necessary to match the shooting direction at the start of the video of the route 2121 from “506” to “507”.
[0096]
Therefore, as a simple solution to such a problem, for example, the direction at the end of the video of the route 2121 from “502” to “506” is the direction of the node 2111 of “507”, and “506” → The direction of the start of the video reaching “508” starts from the direction of the node 2111 “507”, and the video reaches the node 2111 “508” after the photographing direction is rotated 90 degrees counterclockwise. Assuming that the starting direction of the video from “506” to “507” is the direction of the node 2111 of “507”, all the problematic directions can be matched.
[0097]
However, for example, when an image from the node 2111 “507” to the node 2111 “508” is to be created, the route 2121 becomes “507” → “506”, “506” → “508”. In order to reuse the video, the video from “507” to “506” must be rotated 180 degrees after reaching the node 2111 “506”. This is because in the video “507” → “506”, the orientation is opposite to the node 2111 “507”, but the orientation is adjusted to the video “506” → “508” at the node 2111 “506”. This is because the direction of the node 2111 “507” must be pointed. Moreover, the user rotates 180 degrees at the node 2111 “506” at the end of the video of the route 2121 from “507” to “506”, and then starts the video of the route 2121 from “506” to “508”. At that time, an image rotated 90 degrees counterclockwise will be seen, and it is conceivable that the rotation is confused a lot.
[0098]
As described above, such problems frequently occur as the number of nodes 2111 and routes 2121 increases.
[0099]
In the present embodiment, in view of the problems described above, the periphery of each node 2111 is recorded as a panoramic image 2255, and two images positioned before and after the node 2111 are displayed as rotated images based on the panoramic image 2255. A process for smoothly connecting the routes 2121 is executed. That is, the server 101 records the start direction of the panoramic image 2255 in the hard disk {circle around (2)} 131 in association with the panoramic image 2255. Then, when guiding from the first point to the second point with the moving image of the route 2121 connecting them, the node 2111 located between the plurality of routes 2121 from the first point to the second point If the direction of the end point of the preceding route 2121 image reaching the node 2111 is different from the direction of the starting point of the subsequent route 2121 image starting from the node 2111, the panorama image 2255 recorded around the node 2111 and A rotation image is created using the information of the starting direction. In this way, after the end of the route 2121 video reaching the node 2111, the created rotated image is inserted, and then the route 2121 video starting from the node 2111 is started. As a result, the two routes 2121 positioned before and after the node 2111 are smoothly connected.
[0100]
The process described above will be described in more detail with reference to FIGS.
[0101]
FIG. 9 is a schematic block diagram of the search guidance system. In the present embodiment, the server 101 includes a streaming video server 141. The streaming video server 141 has two roles: an encoder that creates (encodes) streaming-compatible data, and a distribution server that performs distribution. As another embodiment, the server 101 may function as an encoder, and the streaming video server 141 may be divided so as to function only as a distribution server. In addition, streaming video playback software is installed in the client 201 which is a user terminal. Therefore, the client 201 functions as a player that receives and reproduces streaming-compatible data. The streaming distribution method executed by the system of this embodiment that executes such streaming technology includes an on-demand distribution method in which encoded data is stored once in a file and then distributed by a distribution server, and encoding and distribution Any of the live distribution methods for performing real-time distribution in parallel may be adopted.
[0102]
The server 101 stores and saves the moving image from the start point to the end point of the route 2121 and the panorama image 2255 of the node 2111 for all the routes 2121 and nodes 2111 in the hard disk {circle around (2)} 131. That is, the hard disk {circle over (2)} 131 functions as a database that stores and saves the moving image video from the start point to the end point of the route 2121 and the panorama image 2255 of the node 2111 for all the routes 2121 and the nodes 2111. Therefore, the server 101, for all the routes 2121 and nodes 2111 from the first point to the second point, the moving image video from the start point to the end point of the route 2121 stored and stored in the hard disk (2) 131 and A rotated video based on the panorama image 2255 of the node 2111 that smoothly connects the routes 2121 is created as a route video list, and the created route video list is passed to the streaming video server 141. Thereby, the streaming video server 141 creates a route video so as to be compatible with streaming based on the route video list. Therefore, the client 201, which is a user terminal, can play the downloaded route video list while accessing the streaming video server 141 and downloading the route video by using the installed streaming video playback software.
[0103]
FIG. 10 shows a route video list creation process in the server 101 when a route video designation object 2241 with an explanation of “view all route videos continuously” is clicked on the guidance screen 2001 shown in FIG. It is a flowchart which shows a flow.
[0104]
When the route video designation object 2241 is clicked (step S201), the server 101 stores a hard disk {2} 131 which is a database for storing and saving the moving image video from the start point to the end point of the route 2121 and the panorama image 2255 of the node 2111. And a second process of connecting the end point of the preceding route 2121 and the starting point of the subsequent route 2121 with the rotated video based on the panoramic image 2255 in the node 2111 (reproducing means, reproducing step) ). In the present embodiment, when executing the second process, the server 101 creates a route video list and passes it to the streaming video server 141, and the streaming video server 141 can stream the actual route video. Generate in format. As a result, the route image from the first point to the second point in the calculated route order can be reproduced by the client 201 as the user terminal.
[0105]
Here, creation of a route video list in the server 101 will be described in more detail. First, the CGI program installed in the hard disk {circle around (1)} 121 of the server 101 reaches all the combined video numbers Z from the first point as the starting point to the second point as the destination point. The video of the optimal route 2121 is added to the route video list (steps S202 to S208). In order to realize such processing, first, the first route 2121 video is added to the route video list (step S202). At this time, for example, “1” is set as a value of N indicating the order of the route 2121 video in a counter or the like. Then, it is determined whether or not N has reached all the combined video numbers Z, that is, the number Z of all the routes 2121 from the first point that is the starting point to the second point that is the reaching point ( In step S203), if Z = N (Y in step S203), the route video list is completed, and the route video list after creation is passed to the streaming video server 141 (step S204). As a result, the created route video can be streamed to the client 201 which is the user terminal.
[0106]
On the other hand, when Z = N is not satisfied, that is, when N does not reach the number Z of all the routes 2121 from the first point as the starting point to the second point as the destination point ( In step S203 N), the N + th route 2121 video is added to the route video list (step S202), N set in the count is updated to N + (step S208), and the process returns to step S203. At this time, if the angle at the end of the Nth route 2121 image is equal to the angle at the start of the (N + 1) th route 2121 image (Y in step S205), the N + 1th route 2121 image is simply displayed. It is only added to the route video list (step S207). Otherwise (N in step S205), a rotated video is created based on the panorama image 2255 of the node 2111, and this rotated video is added to the route video list. After the addition (step S206), the (N + 1) th route 2121 video is added to the route video list (step S207). In this case, the rotated video based on the panoramic image 2255 of the node 2111 is a rotated video that smoothly connects the (N + 1) th route 2121 video and the (N + 1) th route 2121 video. The server 101 generates a rotated video based on the panorama image 2255 of such a node 2111.
[0107]
The route video list by the server 101 as described above is described in the XML description language shown in FIGS. 11 to 13 as an example. That is, the server 101 creates a route video list in an XML description language as exemplified in FIGS. The route picture list of the XML description language illustrated in FIGS. 11 to 13 has a series of contents linked to FIGS. 11 to 12 and FIGS. Here, FIG. 11 to FIG. 13 are only shown separately because of space problems in drawing representation. Hereinafter, a route video list using such an XML description language will be described in detail.
[0108]
First, in the path video list in the XML description language, still picture information is described in the still picture information description area shown in FIGS.
[0109]
For example, for the still image of the end / start video (they are the same image) in the node 2111 “506”, information is described in a tag of <image id = “S506”>. href = “...” is a link to the still image file. xSize is the number of pixels in the X direction of the image. ySize is the number of pixels in the Y direction of the image. The vertical Angle is a vertical angle of view. Horizontal Angle is a horizontal angle of view. AngleDirection is a direction in which the center of the still image is directed.
[0110]
Further, the panoramic image 2255 in the node 2111 “506” has information described in a tag <panoramicImage id = “P506”>. href, xSize, ySize, angleDirection, verticalAngle have the same meaning as the <image ..> tag. RotationImageHref means a 360 degree panoramic image 2255. rotationImageXSize and rotationImageYSize are the numbers of pixels in the X and Y directions in such a panoramic image 2255.
[0111]
With respect to the nodes 2111 “507” and “508”, the information of the still image of the end / start video and the panoramic image 2255 is described in the same manner.
[0112]
Next, in the path video list in the XML description language, information of the node 2111 is described in the node information description area shown in FIGS.
[0113]
For example, the ID of the node 2111 “506” is described as <naviNode id = “N506”>, and id = “N506”. The <link> tag represents a link to a related image or the like, and represents what the link is based on the type attribute.
[0114]
In this case, the link to the still image of the end / start video in the node 2111 “506” is <link type = "image" idref = "S506" />, and the link to the panoramic image 2255 is <link type = "panoramicImage". It is described as id = "P506" />.
[0115]
With respect to the nodes 2111 “507” and “508”, the information of the still image of the end / start video and the panoramic image 2255 is described in the same manner.
[0116]
Further, in the route video list in the XML description language, information on the route 2121 is described in the route information description area shown in FIG.
[0117]
For example, the route 2121 from the node 2111 “502” to “506” is described in a portion surrounded by tags <naviRoute id = “R502-506”>. The <routeLength> tag represents the distance of the route 2121. The <startNaviNode> tag represents the ID of the start node. The <endNaviNode> tag represents the ID of the end node 2111. In <routeFile>, a link to the video of the route 2121 is described as the attribute href.
[0118]
FIG. 14 is a schematic diagram visually showing a procedure for creating a rotated video from the panoramic image 2255. The upper part of FIG. 14 is an image at the end of the route 2121 to a certain node 2111. The corresponding <naviNode> can be determined from the ID of the end node 2111 in the <endNaviNode> tag described in the <naviRoute> tag, and the id attribute described in <link type = "image"> described in that <naviNode> Thus, the image at the end can be determined, and the angle a can be determined from the angle Direction described in the id attribute.
[0119]
In the same way, the angle d of the image (lower stage) at the start of the route 2121 to the next node 2111 can be determined.
[0120]
In the same way, the start angle e of the panorama image 2255 (middle stage) can be determined. Further, pixel positions b and c in the X direction on the panoramic image 2255 corresponding to the angles a and d can be determined from the XSize of the panoramic image 2255. The calculation formula is
b = (5140/360) × a
d = (5140/360) × c
It is. For example, when a = 180, d = 90, e = 0, and XSize = 5140 written in the panoramicImage tag, b = 2570 and d = 1285.
[0121]
From this, the amount of moving pixels on the panorama image 2255 is known. Therefore, it is possible to create a rotated video that moves from the pixel position b of the panoramic image 2255 to the pixel position c. Creation of a rotating video can be easily performed by describing it in, for example, the realPix language provided by real networks, so that the description thereof is omitted here.
[0122]
Then, by adding the rotated video of the node 2111 connecting the two routes 2121 between the moving images of the two routes 2121 having different end directions and starting directions to the route video list, guidance in which the video directions are smoothly connected. The route image can be provided to the user. At this time, when switching between the rotated image and the route 2121 image before and after it, an image using effects such as a crossfade effect and a dissolve effect is displayed, thereby reducing the difference in the connection portion and smoothing the connection. Can be. Since the cross-fade effect and dissolve effect are conventional techniques, description thereof is omitted.
[0123]
The method of smoothly connecting the two routes 2121 by the rotated video based on the panoramic image 2255 in the node 2111 described above can be applied to the first point as the starting point and the second point as the reaching point. In other words, for example, in a dialog box, it is assumed that any angle value can be input as the starting direction at the first point as the starting point and the ending direction at the second point as the reaching point. When a route video designation object 2241 with an explanation of “viewing the route video continuously” is clicked, the start direction and end direction of each input video are referred to, and if necessary, rotated from the panoramic image 2255 Create a video. Thus, if the direction of the moving image at the starting point of the route 2121 at the first point is different from the direction at which the guidance starts, the direction of starting the guiding and the direction of the moving image at the starting point of the route 2121 at the first point are set to the first. It is possible to connect with a rotated video based on the panoramic image 2255 of the node 2111 at the point. If the direction of the moving image at the end point of the route 2121 at the second point is different from the desired direction, the direction of the moving image at the end point of the route 2121 at the second point and the desired direction are set as a node at the second point. It is possible to connect with a rotated video based on the 2111 panoramic image 2255. Thereby, it is possible to provide guidance information that is easier to visually recognize.
[0124]
FIG. 15 is a schematic diagram visually showing a procedure different from that in FIG. 14 for creating a rotated video from the panoramic image 2255. That is, the method illustrated as a schematic diagram in FIG. 15 refers to the horizontal component and the vertical component when generating a rotated video from the panoramic image 2255, and detects the vertical shift between two images connected by the rotated video. Are also connected. Specifically, based on verticalAngle (iv), horizontalAngle (ih) described in <image> tag and verticalAngle (pv) written in <panoramicImage> tag, a rotating image that is connected more smoothly is created. .
[0125]
If the value described in the panoramicImage tag is used as the value of XSize and YSize, the pixel range (X, Y) in the frame surrounding the parts b and c in FIG.
X = (XSize / 360) × ih
Y = (YSize / pv) × iv
The coordinates of the upper left (px1, py1) and lower right (px2, py2) of the b frame on the panoramic image 2255 are
(Px1, py1) = (b−X / 2, YSize / 2−Y)
(Px2, py2) = (b + X / 2, YSize / 2 + Y)
(However, an approximate expression when the subject is at ∞).
[0126]
Accordingly, it is possible to create a rotated video that starts from a frame portion surrounding b at the pixel position b of the panoramic image 2255 and moves into the frame portion surrounding c at the pixel position c. Therefore, the direction change of the route image at the node 2111 can be made smoother, and the quality of the guidance information can be further improved.
[0127]
FIGS. 16 and 17 are schematic diagrams visually showing a procedure different from FIGS. 14 and 15 for creating a rotated video from the panoramic image 2255. FIG. That is, the panoramic image 2255 is a 360-degree image, and the left and right end portions of the panoramic image 2255 illustrated in FIG. 16 are connected without a seam. However, since the actual image file is expressed as a two-dimensional image, the coordinates in the X direction have a start point and an end point. For this reason, depending on the designation of the angle, a part of the frame of the corresponding part may protrude from the end (see b of FIG. 16) or completely (see c of FIG. 16). At this time, when creating a rotating image, it is necessary to perform exception determination for such an exception and generate a necessary still image for each case. Therefore, as illustrated in FIG. 17, by connecting two panoramic images 2255 in advance to form a 720 degree image, if the rotation angle is within 360 degrees, a rotated image can be created without making an exception determination. Can do. Accordingly, the node 2111 and the route 2121 before and after the node 2111 can be correctly connected, and the direction change of the route image at the node 2111 can be made smooth.
[0128]
Here, the panorama image 2255 may be stored and saved in advance as a 720 degree panorama image in the hard disk (2) 131 of the server 101, or may be a 720 degree panorama image when the server 101 creates a route video list. It ’s okay.
[0129]
18 is a route video list creation process different from that in FIG. 10 when a route video designation object 2241 with an explanation of “view all route videos continuously” is clicked on the guidance screen 2001 shown in FIG. It is a flowchart which shows the flow. However, also in the flowchart illustrated in FIG. 18, the basic processing flow is the same as that in the flowchart illustrated in FIG. 10. A different point is that the panoramic image 2255 is required in the node 2111 connecting the two routes 2121, but the required panoramic image 2255 does not exist in the hard disk {circle around (2)} 131 of the server 101.
[0130]
That is, as described above, when N does not reach the number Z of all the routes 2121 from the first point that is the starting point to the second point that is the reaching point (N in step S203). The N + th route 2121 video is added to the route video list (step S202), N set in the count is updated to N + (step S208), and the process returns to step S203. At this time, if the angle at the end of the Nth route 2121 image is equal to the angle at the start of the (N + 1) th route 2121 image (Y in step S205), the N + 1th route 2121 image is simply displayed. It is only added to the route video list (step S207). Otherwise (N in step S205), a rotated video is created based on the panorama image 2255 of the node 2111, and this rotated video is added to the route video list. After the addition (step S206), the (N + 1) th route 2121 video is added to the route video list (step S207).
[0131]
Here, in the flowchart illustrated in FIG. 10, when it is determined in step S205 that the angle at the end of the Nth route 2121 video is not equal to the angle at the start of the (N + 1) th route 2121 video ( N) in step S205, a panoramic image corresponding to the hard disk {circle around (2)} 131 of the server 101 is created prior to the processing in step S206 which creates a rotated video based on the panoramic image 2255 of the node 2111 and adds this rotated video to the route video list. It is determined whether or not 2255 exists (step S301). As a result of the determination, if it is determined that the corresponding panoramic image 2255 exists, the process of step S206 is executed to create a rotated video based on the panoramic image 2255 of the node 2111 and add this rotated video to the route video list. . On the other hand, as a result of the determination in step S301, if it is determined that the corresponding panoramic image 2255 does not exist (N in step S301), an image that displays the angle necessary for changing the orientation as characters. Is added to the route video list (step S302), and then the process proceeds to step S207. Accordingly, when a path video list to which an image for displaying the angle necessary for changing the orientation as characters is added to the streaming video server 141, the client accessing the streaming video server 141 In 201, it is possible to perform streaming display at least how many times the images of the two routes 2121 preceding and following are rotating. Thus, even when there is no panoramic image 2255 to be used on the hard disk {circle around (2)} 131 of the server 101, the user can be informed of how much the video orientation before and after the node 2111 has changed.
