To do. The probe information includes the ID of the vehicle (identification information of the vehicle or the probe information providing apparatus 101), vehicle state information, vehicle position information, and time information. The vehicle state information includes door state information (information on whether the door is open or closed).

  In the present embodiment, in a vehicle equipped with a camera, video data around the vehicle photographed by the camera is included in the probe information. Alternatively, as probe information different from the probe information, probe information including video data around the vehicle photographed by the camera is transmitted (uploaded) to the meeting place presentation device 102 at predetermined time intervals or irregularly. To do.

  The communication means (communication method) between the in-vehicle probe information providing apparatus 101 and the meeting place presentation apparatus 102 is not particularly limited. Transmission / reception may be performed by transmitting (uploading) probe information in real time from a vehicle using wireless communication, or by recording the probe information in a medium and uploading it later to the probe database 303 of the meeting place presentation device 102. good.

  The meeting place presentation device 102 accepts request information RQ (request signal) including a designated position to wait for from the place information notification device 100. Upon receiving the request information RQ, the meeting place presentation device 102 extracts, from the probe database 303, a place where the number of vehicles whose doors are opened in the vicinity of the designated position is equal to or more than a preset number as a meeting place. And the meeting place presentation apparatus 102 proposes a meeting place by transmitting the extracted information on the meeting place to the requesting place information notification apparatus 100. The information on the meeting place may be position information or a place name such as a facility serving as a landmark.

As shown in FIG. 2, the meeting place presentation device 102 includes a probe information storage unit 300, a request reception unit 301, a meeting place extraction unit 302, an information transmission unit 305, a video presentation processing unit 306, a probe database 303, and a map database 304. Is provided.
The probe information storage unit 300 acquires probe information individually transmitted by the in-vehicle probe information providing apparatus 101 mounted on a plurality of vehicles, and stores the probe information in the probe database 303. As described above, the probe information includes vehicle position information and vehicle door opening / closing information.
The request receiving unit 301 receives request information RQ including information on a designated position.
When receiving the request information RQ, the meeting place extraction unit 302 refers to the probe information in the probe database 303 and extracts the meeting place from the information on the designated position included in the request information RQ.

  As shown in FIG. 3, the meeting place extraction unit 302 of the present embodiment includes a reference position specifying unit 302A, a search range specifying unit 302B, a place determining unit 302C, and a video presentation processing unit 306. The reference position specifying unit 302A performs processing for specifying the reference position from the information on the designated position included in the request information RQ. The reference position is a position that serves as a reference when determining the periphery of the designated position. The search range specifying unit 302B performs processing for determining a search target range based on a search range condition set in advance with the specified reference position as a reference. The place determination unit 302C performs processing for determining a meeting place based on the position information of the vehicle where the door is opened and closed within the search target range. The place determination unit 302C according to the present embodiment sets a place where the number of vehicles whose doors are opened and closed is equal to or more than a preset number as a candidate for a waiting place. The video presentation processing unit 306 performs processing for extracting and presenting video related to the selected meeting place from the probe database 303.

Further, the information transmission unit 305 transmits the information on the meeting place extracted by the meeting place extraction unit 302 as presentation information to the requested location information notification device 100 (the request source that transmitted the request information RQ).
FIG. 4 is an example of the data structure of probe information stored in the probe database 303. In the example illustrated in FIG. 4, the probe information data includes items “id”, “time_stamp”, “lat”, “lon”, and “door”. The item “id” stores vehicle ID information. The item “time_stamp” stores time information. The item “lat” stores latitude information. The item “lon” stores longitude information. The item “door” stores door opening / closing information. Although not shown, other vehicle state information is also stored as needed.

  The location information notification device 100 is mounted as at least one of a hardware configuration and a software configuration on a device that can be used by a user. As a device on which the location information notification device 100 is mounted, for example, a mobile terminal 104 such as a mobile phone, a personal computer 105, and a vehicle 106 including a communication device can be illustrated as shown in FIG. The location information notification device 100 includes a request information transmission unit and a request information transmission unit. The request information transmission unit transmits request information (request signal) including information on the input designated position to the meeting place presentation device 102 in accordance with a user input operation. The request information transmission unit notifies the user by displaying the presentation information received from the meeting place presentation device 102 on the display unit. For example, the position of the meeting place included in the presentation information is displayed superimposed on the map data around the designated position.

  In addition, when the location information notification device 100 detects a user operation for selecting a meeting place and detects a video request operation for the meeting place received and displayed on the display unit, information on the selected meeting place is displayed. The image request information that is included is transmitted to the meeting place presentation device 102. Furthermore, the location information notification device 100 displays the video received from the meeting location presentation device 102 on the display unit in response to the request by the transmission of the video request information.

Note that the video request information may be included in the request information RQ. In this case, all candidates for the meeting place are targeted for transmission. Even in this case, after transmitting the presentation information, only the video corresponding to the request may be transmitted.
The meeting place presentation device 102 composed of the server will be further described (see FIG. 2).

The request receiving unit 301 receives request information RQ including information on a designated position.
The information on the designated position is information on a position where the user's meeting place information is desired. The information on the designated position is, for example, information specified at a POI (Point of Interest) location such as “XX Station South Exit”, “△△ Zoo”, “□□ Co., Ltd.”, latitude / longitude, etc. It is position information specified by the position itself. The facility designated by the POI is a facility with a characteristic that can serve as a landmark.

When the acquired information on the designated position is the position information itself such as latitude and longitude, the reference position specifying unit 302A sets the position as the reference position. When “ΔΔ zoo” or the like is acquired, the map database 304 or the like is referred to, and the position (for example, the entrance to the park or the central location of the place) is obtained as the reference position.
The search range specifying unit 302B determines a search target range based on a preset search range condition with reference to the reference position specified by the reference position specifying unit 302A. The search range specifying unit 302B determines, as the specified search range condition, for example, an area centered on the reference position and having a radius set in advance (for example, a radius of 500 m) as the search target range.

However, when an area-like search condition is included in the received request information RQ, the search condition is prioritized and the search target range is specified by the search condition.
Examples of search conditions included in the request information RQ include search conditions related to areas such as a distance range, search conditions related to a time range, and search conditions related to the number of hits at a meeting place.

  The search condition regarding the area is, for example, a distance condition. The distance condition is, for example, a condition such as “within a radius of 1 km (from the XX station south exit)” or “within a 10-minute walk from (ΔΔ zoo)” together with the information on the designated position. When it is set to 10 minutes on foot, the set time is converted into a distance based on a preset conversion condition to specify a search target range. In addition, the search condition regarding the area may be a directional condition. For example, “Only south side from XX station south exit”. In this case, for example, only the south side with the track as the boundary is set as the search target range.

Search conditions related to the time range are, for example, a specific time zone of the day such as “time zone from 18:00 to 21:00 (in the XX station south exit)” or a specific time zone such as “holiday △ Δ zoo”. The date is specified. The date of “holiday △ Δ zoo” can be specified, for example, by referring to a facility information database (not shown). If it cannot be identified, a message to that effect is sent to the requester.
The search condition regarding the number of hits at the meeting place is set to, for example, “10 (in descending order of frequency of meeting)”.
Further, a search condition for the extraction priority may be set as the search condition. The priority search condition is, for example, the order in which the distance is close to the reference position or the order in which the number of opened and closed vehicles is large.

Search conditions other than the search conditions related to the place are used when determining the waiting candidate in the process of the place determination unit 302C.
The location determination unit 302C extracts from the probe information in the probe database 303 the probe information of the vehicle whose door has been opened and closed within the specified search target range. At this time, if there is a search condition related to the temporal range, probe information that also satisfies the search condition is extracted. The probe information of the vehicle whose door has been opened / closed has the item “door” of the probe information immediately before in the same vehicle (same id) as “closed”, and the target probe information item This is a case where door is “opened” (open information).

  Here, the search target in the probe database 303 may be all data in the probe database 303, or may be data within a preset period, for example. The preset period is, for example, the past year. Further, even when no time condition is specified in the request information RQ, only probe information in a preset time zone including the time when the request information RQ is received may be set as a search target.

  Next, the location determination unit 302C divides the specified search target range into a plurality of locations, and performs voting processing on the extracted probe information with respect to the partitioned locations. Thus, the number of vehicles whose doors are opened and closed is determined for each place. The division is set, for example, by dividing the search target range into a grid having a predetermined size. Also, when voting probe information, for the same vehicle (same id), the voting right for the same place is set to 1, and even if the same vehicle stops at the same place several times, it stops once It is preferable to count.

  Here, the method for identifying the meeting place based on the position of the vehicle where the door is opened and closed is not limited to this. For example, a plurality of set positions may be obtained by performing known statistical processing on a set of position information in the extracted plurality of probe information. In this case, with respect to the plurality of extracted probe information, a plurality of pieces of probe information that are probe information of the same vehicle and whose proximity distances are set in advance are converted into one piece of probe information. Conversion refers to only representative probe information, or conversion into one piece of probe information with the position of the center of gravity of a plurality of probe information groups at close distances as position information.

Then, the place determination unit 302C selects a place where the number of vehicles whose doors are opened and closed is equal to or more than a preset number as a meeting place.
Here, the opening of the vehicle door is equivalent to the person getting on and off, and if it is a position around the POI, it can be considered that the waiting of the person and the vehicle has been performed.
If the number of selected meeting places is the preset number of presentations, the place determination unit 302C extracts the number of presentations from the side with the largest number of vehicles that have been opened and closed.

  The presentation information including the extracted meeting place information is, for example, in a list format. Then, for example, the presentation information is generated by setting the information on the meeting place having a large number of vehicles whose doors have been opened and closed higher, that is, by increasing the priority. Alternatively, the presentation information is generated in the order closer to the reference position (synonymous with the specified position) specified from the specified position, and the higher the closer to the reference position, the higher the presentation information. In other words, priority information is set for the information on the meeting place and used as presentation information.

In addition, if the place determination unit 302C determines from the presentation information in the above list format or the like that the public stop space such as an area where parking is prohibited or a bus stop overlaps with the meeting place position to be presented, the place Is deleted.
The information transmission unit 305 performs processing for transmitting the presentation information created by the location determination unit 302C to the request source.

  When the video presentation processing unit 306 receives video request information including information on a specific meeting place with respect to the presentation information transmitted by the information transmission unit 305, the video presentation processing unit 306 executes processing. The video presentation processing unit 306 extracts, from the probe database, probe information including video data obtained by photographing the location corresponding to the received information on the specific meeting place and its surroundings, and the video data of the extracted probe information is extracted. Process and send the processed video data to the request source.

Here, the probe information includes probe information, that is, vehicle position information when video data is acquired. Further, as the video data information included in the probe information, information on the presence / absence of video data and the direction in which the video was shot is stored. The shooting direction is, for example, the direction of the shooting axis with respect to the longitudinal axis of the vehicle.
The video presentation processing unit 306 refers to the date and time when the extracted video was shot, the shooting position, and the shooting direction, and processes the video according to the user.
If the request information includes a search condition related to the time range, video is extracted according to the specification.

Next, the process of presenting a meeting place in the meeting place presentation device 102 will be described with reference to the flowchart of FIG.
In step S501, the request reception unit 301 receives request information RQ including a designated position related to a meeting place from the user. Specifically, as described above, not only the information on the designated position relating to the position where the user wants to wait but also the search condition such as the search range is received. If the request information RQ is received, the process proceeds to step S502.

In step S <b> 502, the meeting place extraction unit 302 searches for a meeting place from the probe database 303. Specifically, the search target range is specified from the designated position related to the meeting place requested by the user, and the search information of the specified search target range is combined with the information that the door is opened to search.
In step S503, when the corresponding information exists as a result of the search (Yes in S503), the process proceeds to step S504. On the other hand, if the corresponding information does not exist as a result of the search (No in S503), the process proceeds to step S505.

In step S504, the meeting place extraction unit 302 creates presentation information. And the information transmission part 305 transmits the presentation information regarding the meeting place extracted with respect to the user.
In step S505, the information transmission unit 305 notifies the user that there is no corresponding information. In addition, the user is notified that the condition regarding the meeting place is transmitted again.

Next, processing related to video presentation in the meeting place presentation device 102 will be described with reference to the flowchart of FIG. This process is executed by the video presentation processing unit 306.
When receiving video request information including information on a specific meeting place with respect to the presentation information transmitted by the information transmission unit 305, the video presentation processing unit 306 executes processing, and proceeds to step S610.
In step S610, it is determined whether or not there is a time designation in the request information RQ. The time designation is, for example, “time zone from 18:00 to 21:00 (in the XX station south exit)”. If there is a time designation, the process moves to step S620. On the other hand, if no time is specified, the process proceeds to step S630.

  In step S620, a time range is set in the search condition based on the designated time. In the present embodiment, the time range is divided into three time ranges (morning time, noon time, and night time), and the time of the segment where the designated times overlap most is selected. For example, the morning time is set in the range of 4 to 12 o'clock, the daytime is set in the range of 12:00 to 19:00, and the night time is set in the range of 19:00 to 4 o'clock. The number of divisions for dividing the time zone is not limited to three, and the number of divisions may be two or four or more. Also, the specified time itself may be the time range itself of the search condition. At this time, when the range of the designated time is narrow, a range that is expanded, for example, by a preset time (for example, 2 hours) before and after the designated time may be set as the time range to be set. good.

In step S630, it is determined whether or not a date is specified in the search condition in the request information. If the date is specified, the process proceeds to step S640. If no date is specified, the process proceeds to step S650. The date-designated search condition is, for example, designation of “holiday △ Δ zoo” or Saturday.
In step S640, the specified date is set as a search condition for video data.

  In step S650, if the weather at the meeting date and time is known, the search condition is set accordingly. In other words, if the set meeting date / time is current, the weather at the current specified position is acquired. If the set waiting date / time is a future date / time, the weather forecast for that date / time is acquired. Determine whether. When it is determined that it is raining, probe information when it is raining is set as a search condition. When it is determined that it is not raining, probe information when it is not raining is set as a search condition. For example, probe information having wiper use information in the probe information is set as probe information in case of rain. If there is weather information in the probe information, search is performed using that information. When the designation of weather information is received from the request source, the weather information is preferentially adopted.

In step S660, an image satisfying the conditions using the search conditions set in the above processing and an area condition including an area in a preset range (for example, a radius of 60 m) including the target meeting place as a search condition. Probe information including data is extracted from the probe database.
In step S670, if there is no video data satisfying the search condition, the process proceeds to step S680. If the video data can be extracted, the process proceeds to step S690.
In step S680, message information indicating that there is no video around the requested meeting place is selected or created, and is transmitted to the requesting place information notification apparatus 100 in step S730.

On the other hand, in step S690, it is determined whether or not the requesting location information notification device 100 is in-vehicle. For example, if the vehicle ID is transmitted as the identification of the location information notification device 100, it is determined for the vehicle. And if it determines with it being for vehicles, it will transfer to step S700 noting that the passenger | crew of the vehicle requested | required. If the vehicle is not determined to be used, it is determined that the pedestrian is to use it and the process proceeds to step S710.
In step S700 and step S710, an image suitable for the intended use is extracted from the probe information group including the extracted image data.

  In step S700, an image in which it is easy to recognize the meeting place as seen from the vehicle occupant is extracted. In step S700 of this embodiment, video data showing the meeting place or its vicinity is extracted from the road side. For example, as shown in the shooting direction axes P1 to P3 in FIG. 7, the video is taken from a vehicle passing through the road on the waiting location side in the vicinity of the waiting location, and is an image showing the left side from the vehicle, that is, the vehicle Select the images taken from the left side, front left, and rear left. The selection of the video is determined based on, for example, whether the shooting direction of the camera faces the meeting place based on the vehicle position, the camera position, and the position of the meeting place. Here, an image from a vehicle traveling in the lane on the opposite side of the meeting place (in this case, the image on the right side) may be adopted, but it is necessary to select in consideration of the obstruction of visibility by the vehicle traveling on the meeting side. There is. Then, when the extraction (selection) of the video for the vehicle is completed, the process proceeds to step S720.

  In step S710, an image useful for reaching a meeting place from a pedestrian is extracted. In step S710 of the present embodiment, an image showing the road direction (facility on the other side of the road) from the meeting place side is extracted. For example, as shown in the shooting direction axes P4 to P6 in FIG. 7, an image taken from a vehicle passing on a road on the opposite side of the meeting place in the vicinity of the meeting place and showing the left side from the vehicle That is, an image obtained by photographing the left side, the front left side, and the rear left side of the vehicle is selected. The selection of the video is determined based on, for example, the vehicle position, the camera position, and the position of the meeting place, and whether or not the shooting direction of the camera is the direction facing the road side from the meeting place. Here, an image from a vehicle that has traveled in the lane on the meeting place side (in this case, a video on the right side) may be adopted, but in this case, it is necessary to select in consideration of the obstruction in view by the vehicle traveling in the opposite lane. is there. Then, when the extraction (selection) of the video for the vehicle is completed, the process proceeds to step S720.

In step S720, the extracted video is selected and processed.
That is, in step S720, when a plurality of videos are extracted, the videos are selected in a preset priority order. For example, selection is performed under a condition that prioritizes the latest video in time. Alternatively, the selection may be made under a condition that gives priority to a meeting point closer to a preset reference distance. This is because it may become difficult to understand if it is too close to the meeting place.

Here, in the above-described embodiment, the case where the processing in step S690 and the processing in S710 are performed exclusively has been described. However, the processing in step S690 and the processing in S710 are performed, and both videos are transmitted. It is good also as composition to do.
Further, as the processing, a plurality of videos continuously acquired along the meeting place may be used and processed into panoramic video data obtained by synthesizing the videos. In the case of a panoramic image, for example, probe information from a vehicle that has uploaded probe information showing a meeting place or a place opposite to the meeting place across a road is used. Specifically, using the continuous video data taken before and after the meeting place along the run, the panoramic video is processed as if it was continuously connected for a preset distance (for example, 20 m). .

In step S730, the video is transmitted to the request source.
The above process is repeated as many times as the number of meeting places selected. The transmission may be batch transmission. Note that the extraction and processing of the video data may be performed in advance. Further, when there is video information in which a characteristic structure relating to the meeting place is projected in the map data, the video data may be transmitted as the video information.

(Operation other)
An operation of the meeting place extraction unit 302 when receiving request information RQ including a designated position to be waited for such as “XX station south exit” from the user will be described.
The meeting place extraction unit 302 performs a process for extracting a meeting place when the request receiving unit 301 receives request information RQ including information on a designated position that indicates a place to be waited for. First, the meeting place extraction unit 302 specifies a search target range based on the received information on the designated position. Then, the meeting place extraction unit 302 extracts, from the probe database 303, probe information that is information on a vehicle that has uploaded probe information within the specified search target range and has information that the door is opened. Whether the vehicle has uploaded probe information within the search target range is searched using latitude information (lat) and longitude information (lon) in FIG. Whether the door is opened or not is determined by door opening / closing information (door) in FIG.

By the above process, it is possible to extract the information on the vehicle whose door is opened around the designated position received, that is, the information on the position of the vehicle that may have waited.
Next, the meeting place extraction unit 302 divides the specified search target range into a plurality of sections according to preset conditions, and information on designated positions written in the extracted probe information data for each section. Voting is performed using (latitude information (lat), longitude information (lon)).

  Here, when the probe information is uploaded at a rate of once per second, the information that the door is open at a certain position is uploaded for the time that the door is open. For this reason, the search is hit in proportion to the time when the vehicle is stopped. That is, if the door of a certain vehicle is opened for 10 seconds, the opened of the door opening / closing information (door) will be 10 hits. As described above, when the doors are opened continuously in time, or when the position information at that time is almost the same, processing is performed so that the waiting is counted once. In the above embodiment, the processing is described with reference to the door information of the previous data, but there is only one probe information of the same vehicle that is continuously door opening information at the same vehicle position. You may process as.

In the present embodiment, an example is described in which the process of counting one time is performed even when there are a plurality of pieces of probe information that are opened and closed when the same vehicle stops at the same place.
By performing such processing, the meeting place extraction unit 302 can extract information on the designated position of the meeting place (latitude information (lat), longitude information (lon)) and hit number information.
Then, the meeting place extraction unit 302 extracts a section (place) where the number of hits is equal to or greater than a preset threshold value as a waiting place candidate.

  Although the search range is not described in the above description, for example, when a distance range such as “within a radius of 1 km from the XX station south exit” is specified as a search condition, the radius is within 1 km centered on the received specified position. You can search by crossing the vehicle that uploaded the probe information and the information that the door was opened. When a time range such as “XX station south exit in the time zone from 18:00 to 21:00” is designated, the vehicle and the door opened information on the probe information around the received position, and further, 18 The search may be performed by multiplying within the time zone from time to 21:00 (time information (time_stamp) in FIG. 2).

  The same applies to the search conditions. When a condition such as “10 in descending order of frequency of waiting” is designated, the top 10 having the highest number of hits among the waiting places extracted by the waiting place extracting unit 302. Just pick out about. When a condition such as “in order from □□ Co., Ltd.” is designated, ten queuing locations extracted by the queuing location extraction unit 302 may be extracted in order from “□□ Co., Ltd.”.

  Then, the information transmission unit 305 transmits information on the meeting place extracted by the meeting place extraction unit 302 to the requesting place information notification apparatus 100. The location information notification device 100 performs display processing for presenting a meeting place on a display unit of a device on which the location information notification device 100 is mounted. For example, the location information notification device 100 synthesizes and displays the position data of the meeting place acquired from the meeting place presentation device 102 on the map data including the designated position so as to overlap. The position of the meeting place is displayed by a number, for example, and the higher the priority, the smaller the number, for example.

FIG. 8 is a display example of information related to the meeting place that the location information notification device 100 presents to the user.
A display screen 401 is a screen of a display unit mounted on a device such as a mobile phone on which the location information notification device 100 is mounted. A display area 402 of the display screen 401 is a request regarding a position where a user wants to wait, and information on a specified position, a search range, and a search condition are described therein. A display area 403 shows the meeting place extracted by the meeting place extraction unit 302 on the map viewer. In this figure, for the sake of simplicity, candidates for the meeting place are presented with four circle numbers (1) to (4). A display area 404 shows detailed information on the extracted meeting places (1) to (4). In this figure, the extracted position information and the number of search hits are displayed. For example, when the meeting place (2) is selected on the display area 403, a screen interface may be considered in which the information in the display area 404 is changed to the information on the meeting place (2).

Furthermore, when the location information notification device 100 detects that the user has selected one of the displayed waiting locations, and further detects that a video request has been selected, the location information notification device 100 is selected. A video request signal including information specifying the meeting place is transmitted to the meeting place presentation device.
When the meeting place presentation device receives the image request signal, the image presentation processing unit 306 extracts the image related to the selected meeting place and, if necessary, transmits it to the request source place information notification device 100.

The location information notification device 100 displays the received video data that has been transmitted on the display unit. FIG. 8 schematically shows that the video transmitted to the video display unit 405 is displayed. In the example of FIG. 8, the case where the image | video of the front-back and left-right 4 directions image | photographed with the vehicle which existed in the vicinity of the target meeting place is illustrated.
At this time, in the case of the location information notification device 100 mounted on a mobile terminal such as a mobile phone, the video to be displayed is a video obtained by photographing the road side direction from the meeting place. For this reason, when the user walks on the sidewalk and heads for a meeting, the user confirms with a video viewed from the pedestrian, so that it is easy to understand for the pedestrian who heads for the meeting place. On the other hand, in the case of the location information notification device 100 mounted on the vehicle, the video is an image that captures the meeting place from the vehicle side, and thus is easy to understand for the vehicle occupant. Thus, when considering reaching the meeting place, an image that is easy to understand for a vehicle occupant or a pedestrian is presented.

Further, in the case of a panoramic image, since it is a continuous image toward the meeting place, it is more difficult to make a mistake when moving to the meeting place.
In addition, by presenting the video to the user, it can be used as a reference when determining the meeting place. For example, when viewing the video, if the candidate for the meeting place is another person's parking lot, the user can determine that the position should not be the meeting place.

  Also, by providing an image close to the state when waiting as an image, it is possible to provide an image regarding a meeting place that is closer to the state of waiting. In other words, by presenting a video corresponding to the scene to be waited for to the user, it can be used as a reference when determining the meeting place. For example, it is easy to stop in the morning, but it is safe to meet in a place that is difficult to stop at night or stop on weekdays. It is effective in such a scene.

In addition, it is easy to specify a meeting place by adopting an image showing a characteristic structure (POI) as a mark.
With the above system, information on the opening of the door is searched from probe information transmitted (uploaded) from a plurality of vehicles, the corresponding position is extracted as a meeting place, and provided to the user. By doing so, it is possible to propose a place where there is a high possibility that the meeting has actually been performed in the past, and thus it is possible to provide useful information to the user. Further, providing the video makes it easier to determine the selection of the meeting place and makes it easier to reach the selected meeting place.

(Modification)
(1) In the above embodiment, a configuration has been described in which, when a meeting place is selected by the place information notification apparatus 100 and a video request is made, the waiting place presentation apparatus transmits video data to the request source. Even when there is no video request, the video data may be transmitted together when presenting candidate information on the meeting place. In this case, it is preferable that information on the presence / absence of video is included in the request information RQ including the designated position.

(2) As a video processing process, a plurality of videos showing the waiting area may be processed into videos mapped in a three-dimensional space. In this case, the mapping process is performed from the viewpoint of the driver's seat or from the viewpoint of the sidewalk for pedestrians depending on whether the vehicle or the pedestrian. The mapping process in the three-dimensional space may use known video processing.
(3) Also. As the image processing process, a process of processing a plurality of images taken by a plurality of cameras mounted on a specific vehicle into one image may be performed.

(4) When extracting video data, the map database 304 may be referenced to search for information on characteristic structures in the target meeting place and its surroundings. At this time, when a characteristic structure (POI) is searched for, an image may be extracted based on the position of the characteristic structure. In this case, video data on which a characteristic structure (POI) is projected can be presented, and a meeting place can be specified more.
When the video presentation processing unit 306 provides a video showing a road in the opposite direction from the meeting place side, the video database 304 refers to the map database 304 or the like and there is a structure such as a building characteristic in that direction. In this case, it is preferable to adopt a configuration in which video data in which the shooting axis is directed in the direction of the characteristic structure is extracted.

(5) Information on the meeting place may be converted into information such as an address or a front of a building by referring to the map database 304.
(6) Moreover, when the position of the meeting place overlaps with the parking / parking prohibition position or the position of the public parking lot, it may be excluded from the extraction result.
(7) Conversely, if the location of the meeting place is a pickup lane (a stop space for general vehicles) set in a plaza in front of the station, it may be preferentially proposed to the user.

(8) In the above-described embodiment, the case where the user specifies and requests information on a place where the user wants to meet is illustrated. Instead of this, information on the current position when the user operates a device on which the location information notification device 100 is mounted may be information on the designated position included in the request information RQ. The current position may be specified by GPS or the like.
For example, when a pedestrian who is a mobile terminal such as a mobile phone and has a mobile terminal equipped with the location information notification device 100 operates the mobile terminal and transmits an information provision request for a meeting place, the current location of the pedestrian The surrounding meeting places will be extracted and presented.

In this case, in FIG. 3, the request receiving unit 301 receives current position information by a current position detection device such as a GPS provided in a terminal (for example, a mobile phone 104, a personal computer 105, or a vehicle 106 having communication devices) possessed by the user. To do. The current position information is specifically latitude / longitude information. The processing in the meeting place extraction unit 302 is performed as described above.
In this case, the user can obtain information on the meeting place around the current position without determining the meeting place in advance.

(9) Information on the waiting party may be set in the request information RQ. For example, the information on the meeting partner is a symbol written on, for example, an automobile registration number mark (number plate). The meeting place presentation device 102 specifies a target vehicle by a vehicle database or the like, and if the specified vehicle is communicable, for example, after inquiring, transmits information on the extracted meeting place. At this time, when there is information on the meeting place selected from the vehicle, the selected place may be presented to the request source that transmitted the request information RQ. In this case, a meeting place where the vehicle occupant can easily go can be presented to the request source. In this case, the video data relating to the meeting place may be transmitted to the meeting partner. In this case, it is preferable to transmit the video of the meeting place selected from the meeting partner.
Here, the probe information accumulating unit 300 constitutes a video information receiving unit.
