Description

  The present invention relates to an information processing apparatus and a computer program capable of acquiring own device position information representing the own device position.

  In recent years, disaster prevention measures due to abnormal weather such as heavy rain have attracted attention. For example, in a navigation device or the like capable of grasping the position of the user's own device, the user can move while avoiding the rainy area by making it possible to confirm the raining area on the map.

  As a technology for realizing such a situation, a navigation device has been proposed that displays weather conditions such as rain and sunny on a map in duplicate, and is used as a judgment material when grasping the situation and determining a destination or traveling route. (For example, refer to Patent Document 1).

  Under such circumstances, the operation of the “VICS Wide (registered trademark)” system has been started from April 23, 2015 by the Road Traffic Information and Communication System Center in Japan. In this system, as one of services, information relating to a heavy rain area that can be used by a navigation device or the like is actually provided (for example, see Non-Patent Document 1).

JP 2000-193469 A Road Traffic Information and Communication System Center, "4. Display heavy rain area", [Search on December 21, 2015], Internet <URL: http://www.vics.or.jp/know/wide /04.html>

  However, such an area requiring vigilance due to heavy rain (a vigilance area) fluctuates with the passage of time, so in a conventional navigation device, it is grasped whether the vigilance area tends to approach or move away. It was difficult.

  The present invention has been made in view of such circumstances, and provides an information processing apparatus and a computer program that can easily grasp the positional relationship with a warning area that varies with the passage of time.

  An information processing apparatus according to the present invention is an information processing apparatus capable of acquiring own apparatus position information representing an own apparatus position, and includes area information acquisition means for acquiring area information related to a warning area, the own apparatus position information, Using the area information, a calculation means for calculating the distance from the own aircraft position to the warning area, and the distance calculated by the calculation means is set as a reference value, and a new comparison calculated by the calculation means The comparison means for comparing the distance for use and the reference value, and the output means for outputting according to the comparison result of the comparison means.

  With such a configuration, the distance from the own device position calculated using the own device position information and the area information by the calculating means to the warning area is set as the reference value by the comparing means, and the new value calculated by the calculating means is calculated. The comparison distance and the reference value are compared. Then, output according to the comparison result is performed by the output means. As a result, a change in the positional relationship between the position of the aircraft and the warning area is determined, and output according to the determination result is performed. For example, when the distance for comparison is shorter than the reference value, it is possible to determine that the position of the own aircraft tends to approach the warning area and notify that the warning area tends to approach. Further, for example, when the comparison distance is longer than the reference value, it is determined that the position of the own device tends to move away from the alert area, and the notification can be canceled.

  In the information processing apparatus according to the present invention, the calculation unit calculates a distance as the reference value using own device position information indicating the own device position before a predetermined time and area information regarding the warning area before the predetermined time. Then, the comparison distance can be calculated using own device position information indicating the current device position at the current time and area information regarding the alert area at the current time.

  With such a configuration, the calculation unit calculates the distance as the reference value using the own device position information indicating the own device position before the predetermined time and the area information regarding the warning area before the predetermined time, and the own device at the current time is calculated. A comparison distance is calculated using the position information representing the position and the area information regarding the alert area at the current time. As a result, the change in the positional relationship between the own aircraft position and the warning area from a predetermined time before to the current time is determined, and it is grasped whether the own aircraft position and the warning area tend to approach or move away at the current time. be able to.

  In the information processing apparatus according to the present invention, route guidance means for performing route guidance from the own device position to a predetermined destination, and predicting the own device position on the route predicted after a predetermined time has elapsed from the current time. Predicting means, and the calculating means calculates the distance as the reference value using own apparatus position information indicating the own apparatus position at the current time and area information relating to a warning area before a predetermined time, The comparison distance may be calculated using own device position information indicating the own device position predicted by the prediction unit and area information regarding the alert area at the current time.

  With such a configuration, the prediction unit predicts the position on the route after the predetermined time has elapsed from the current time. Then, the distance that is the reference value is calculated by using the calculation unit with the own position information indicating the position of the own machine at the current time and the area information regarding the warning area before the predetermined time, and the predicted position is calculated by the prediction unit. A distance for comparison is calculated using the position information of the device to be represented and area information regarding the alert area at the current time. As a result, assuming the tendency of the change in the positional relationship between the own aircraft position and the warning area from the current time until after the elapse of a predetermined time, the position of the own aircraft and the warning area tend to approach or move away after the elapse of the predetermined time. You can predict if there is.

  Further, the information processing apparatus according to the present invention can be configured to vary the output contents of the output means in accordance with a change in distance in the comparison result.

  With such a configuration, the output contents of the output means differ depending on the manner of change in distance in the comparison result, and fine output according to the comparison result can be performed. For example, when the distance for comparison is smaller than the reference value, or when the difference between the reference value and the distance for comparison is a predetermined value or less, the difference between the two may be different, For example, a warning may be given when the comparison distance is half of the reference value. Further, for example, the warning may be canceled when the comparison distance becomes smaller than the reference value, or the alarm is canceled when the comparison distance is longer than the reference value twice in succession. For example, the number of times may be different.

A comparison function for comparing a comparison distance and the reference value, and an output function for performing output in accordance with a comparison result of the comparison function are executed.

  With such a configuration, as with the information processing apparatus described above, the distance from the own device position calculated using the own device position information and area information by the calculation function to the warning area is set as a reference value by the comparison function, The new comparison distance calculated by the calculation function is compared with the reference value. Then, output according to the comparison result is performed by the output function. As a result, a change in the positional relationship with the alert area is determined, and output according to the determination result is performed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  An information processing apparatus according to an embodiment of the present invention is configured as shown in FIG. This information processing apparatus is an in-vehicle apparatus having a navigation unit that supports vehicle driving such as route guidance to a destination.

  In FIG. 1, an in-vehicle device 100 (information processing device) has a processing unit 11 constituted by a computer unit (for example, including a CPU). The processing unit 11 includes an AV unit 17 capable of reproducing various sound sources and video sources (for example, CD, DVD, etc.), and a navigation unit 18 (navigation) that performs navigation processing such as route guidance to a vehicle destination. Device) is connected. Further, an output circuit 15 connected to the speaker 16 is connected to the processing unit 11, and an audio signal based on the processing of the AV unit 17 and the navigation unit 18 is output under the control of the processing unit 11. Is provided to the speaker 16 and the sound based on the audio signal is emitted from the speaker 16. Furthermore, the processing unit 11 includes a storage unit 14 (for example, a hard disk drive) that stores various information such as music information and map information used in the AV unit 17 and the navigation unit 18, and an LCD. The display unit 13 is connected to an operation unit 12 that includes a touch panel on the display unit 13 and is used to input processing instructions and various information. Under the control of the processing unit 11, the display unit 13 displays video from the AV unit 17, images such as maps and guidance routes based on processing in the navigation unit 18, and various information based on notification settings, which will be described later. The

  The in-vehicle device 100 includes a receiving unit 19 that can receive road traffic information transmitted from the outside using FM multiplex broadcasting or the like under the control of the processing unit 11. Specifically, this road traffic information is information provided by the “VICS Wide (registered trademark)” system, and is provided at predetermined intervals (specifically, 12: 5, 12:10, etc.). Updated every 5 minutes). This road traffic information includes information about a warning area (hereinafter referred to as area information) indicating an area where heavy rain (for example, rain of “50 mm / hour” or more, which is assumed to be rainfall intensity at which the driver's forward visibility is reduced) is falling. Called). The processing unit 11 manages time information by a time measuring means (not shown) such as a timer, and is configured to be able to extract area information from the road traffic information received by the receiving unit 19 at predetermined time intervals. The area information will be described in detail later with reference to the drawings.

  In such a configuration, when a switch that is operated when the vehicle is started, for example, an accessory switch (ACC), is turned on, and the notification setting regarding the warning area is made by the user operation or the like in the in-vehicle device 100, the processing unit 11 Performs processing according to the procedure (part 1) shown in FIG.

  First, the processing unit 11 determines the presence / absence of notification setting cancellation (S11). If it is determined that the notification setting has not been canceled (the setting is maintained) (YES in S11), the reception timing of the area information is further determined. It is determined whether or not (S12). For example, this reception timing is set to a timing of the same time interval as the update period of the transmitted area information, specifically, every 5 minutes from a predetermined time (for example, the time when ACC is turned on).

  If it is determined that it is not the reception timing (NO in S12), the processing unit 11 returns the process to S11. On the other hand, when it is determined that it is the reception timing (YES in S12), the processing unit 11 positions the vehicle-mounted device 100 at the current time via the navigation unit 18 having a positioning function such as GPS (Global Positioning System). Position information (hereinafter referred to as own apparatus position information) representing (own apparatus position) is acquired (S13), and area information is acquired via the receiving unit 19 (S14: area information acquisition means).

  Here, each information will be described with reference to FIG. The own device position information is used to display the own device position 21 on the map 20 displayed on the display unit 13 (FIG. 1). The area information is used for displaying the warning area 22 to be superimposed on the map 20 in units of mesh such as 250 meters square. Thereby, the user can grasp | ascertain intuitively the range where rain is strong. For example, the own device position information is composed of information including the latitude and longitude indicating the specific position, and the area information is composed of information including the latitude and longitude of the mesh end point.

Next, the processing unit 11 calculates the shortest distance X1 from the own device position 21 to the alert area 22 at the current time using the acquired own device position information and area information (S15: calculation means). At this time, since the alert area 22 is formed of a polygon (specifically, a square) as shown in FIG. 3, the distance calculation can be easily performed.
Then, the processing unit 11 determines whether or not a reference value for comparison with the distance X1 is stored in the storage unit 14 (S16). This reference value is calculated at the time of the previous reception, that is, the shortest distance X (see FIG. 4) between the own position 21A and the alert area 22A at the previous reception, and is calculated for the second and subsequent times. Will exist in the case of.

  If it is determined that the reference value is not stored in the storage unit 14 (YES in S16), the processing unit 11 sets the new distance X1 calculated this time as the reference value (distance X) and stores the storage unit 14 (S17), and the process returns to S11. On the other hand, when it is determined that the reference value is stored in the storage unit 14 (NO in S16), the processing unit 11 uses the new distance X1 calculated with information newer than the reference value this time for comparison. The distance is compared with a reference value (distance X), and it is determined whether or not the comparison distance is smaller than the reference value (S18: comparison means).

If the processing unit 11 determines that the comparison distance is smaller than the reference value (YES in S18), the processing unit 11 displays a warning message 23 (see FIG. 5) that the warning area 22 has approached the own device position 21. The information is displayed on the display unit 13 (S19: output means), and the process returns to S11. On the other hand, when it is determined that the comparison distance is not smaller than the reference value (NO in S18), the processing unit 11 returns the process to S11. At this time, if the warning message 23 is displayed, the display of the warning message 23 is canceled.
If it is determined that the notification setting has been canceled in S11 (NO in S11), the processing unit 11 deletes the reference value stored in the storage unit 14 (S20) and ends the process. To do.

According to the vehicle-mounted device 100 (information processing device) as described above, the distance X from the own device position 21A calculated using the own device position information and the area information to the warning area 22A is set as a reference value. The calculated new comparison distance (distance X1) is compared with the reference value. Then, an output corresponding to the comparison result (specifically, a warning message 23 indicating that the warning area is approaching is displayed when the distance for comparison is shorter than the reference value, and the warning message 23 is displayed when the distance is not short. Display is canceled). As a result, a change in the positional relationship between the own aircraft position 21 and the warning area 22 is determined, and an output corresponding to the determination result is performed. Therefore, the positional relationship between the warning area 22 and the own aircraft position 21 that change over time. Can be easily grasped.
In addition, fine output (display) according to the comparison result can be performed by varying the output (display) content in accordance with the mode of change in the distance in the comparison result.

  Further, a distance X as a reference value is calculated using own position information representing the own position 21A before the predetermined time and area information regarding the warning area 22A before the predetermined time, and represents the own position 21 at the current time. A comparison distance (distance X1) is calculated using the position information of the own device and the area information regarding the alert area 22 at the current time. Thereby, a change in the positional relationship between the own aircraft position 21 and the warning area 22 from a predetermined time before to the current time is determined, and the own vehicle position 21 and the warning area 22 tend to approach or move away at the current time. Can be grasped.

  The processing procedure (part 1) by the in-vehicle device 100 described above relates to the notification at the current time, but the processing procedure (part 2) by the in-vehicle device 100 shown in FIG. 6 described below is the current time. The notification is made by predicting after a predetermined time has elapsed. Note that, in the following description, parts different from the processing procedure (part 1) will be mainly described.

  First, the processing unit 11 determines whether or not the notification setting is canceled (S21), and if it is determined that the notification setting is not canceled (YES in S21), it is further determined whether or not it is the reception timing of the area information. (S22). When it is determined that it is not the reception timing (NO in S22), the processing unit 11 returns the process to S21. On the other hand, when it is determined that it is the reception timing (YES in S22), the processing unit 11 acquires its own position information (S23) and also acquires area information (S24: area information acquisition means).

  Further, when the route guidance to the predetermined destination is performed by the navigation unit 18 (route guidance means), the processing unit 11 is on the route 24 after a predetermined time has elapsed from the current time, as shown in FIG. Is predicted (S25: prediction means). For example, this prediction is performed using route information for setting the route 24 and prediction information such as a vehicle speed sensor (not shown).

  Next, the processing unit 11 uses the predicted own position information of the own position 21B and the acquired area information, and the shortest distance from the own position 21B to the alert area 22 at the current time after a predetermined time has elapsed. Y1 is calculated (S26: calculation means). Then, the processing unit 11 determines whether or not the area information acquired at the previous reception timing is stored in the storage unit 14 (S27).

If it is determined that the previous area information is not stored in the storage unit 14 (YES in S27), the processing unit 11 stores the newly acquired area information in the storage unit 14 (S28). To S21. On the other hand, when it is determined that the previous area information is stored in the storage unit 14 (NO in S27), the shortest distance Y from the own position 21 to the previous warning area 22A at the current time (FIG. 8). Reference) is calculated, and the calculated distance Y is set as a reference value (S29; calculation means).
Next, the processing unit 11 compares the new comparison distance (distance Y1) calculated with information newer than the reference value in S26 with the reference value (distance Y), and the comparison distance is greater than the reference value. It is determined whether or not it is small (S30: comparison means).

When it is determined that the comparison distance is smaller than the reference value (YES in S30), the processing unit 11 warns that the warning area 22 is assumed to approach the own position 21B after a predetermined time has elapsed. The message 23A (see FIG. 9) is displayed on the display unit 13 (S31: output means), and the process returns to S21. Thereby, the user can grasp | ascertain that the warning area 22 will approach if it moves along the route | root in route guidance.
On the other hand, when it is determined that the comparison distance is not smaller than the reference value (NO in S30), the processing unit 11 returns the process to S21. At this time, if the warning message 23A is displayed, the display of the warning message 23A is canceled.
If it is determined that the notification setting has been canceled in S21 (NO in S21), the processing unit 11 deletes the area information stored in the storage unit 14 (S32) and ends the process. To do.

  According to the in-vehicle device 100 (information processing device) that performs the processing procedure (part 2) as described above, in addition to performing the processing procedure (part 1), a route after a predetermined time has elapsed from the current time. The own position 21B on 24 can be predicted. Then, a distance Y as a reference value is calculated using the own position information indicating the own position 21 at the current time and the area information regarding the warning area 22A before a predetermined time, and the own position indicating the predicted own position 21B is calculated. A comparison distance (distance Y1) is calculated using the machine position information and the area information regarding the alert area 22 at the current time. As a result, assuming a tendency of a change in the positional relationship between the own aircraft position 21 and the warning area 22 from the current time until a predetermined time has elapsed, the own vehicle position 21 and the warning area 22 tend to approach after the predetermined time has elapsed. It can be predicted whether it tends to go away.

The present invention is not limited to that described in the above-described embodiment, and various modifications can be made.
For example, in the above-described embodiment, the in-vehicle device 100 having the navigation unit 18 as the information processing device has been illustrated. If so, a simple alarm device or the like may be used.
Further, the processing unit 11 and the navigation unit 18 may be integrated.
Furthermore, each function (area information acquisition means, calculation means, etc.) for the processing unit 11 to perform each procedure may be executed by a computer program stored in the storage unit 14 or the like. Specifically, the present invention can be applied to a navigation program for smartphones.

  The processing unit 11 displays the warning messages 23 and 23A on the display unit 13 when it is determined that the comparison distance is smaller than the reference value, and the warning messages 23 and 23A are displayed when it is determined that the distance is not small. Although the display is canceled, the present invention is not limited to this. For example, a warning may be issued when the difference between the reference value and the comparison distance is equal to or less than a predetermined value, or a warning is given when the comparison distance is half the reference value. It may be determined whether or not to perform. The time when the own device position 21 enters the alert area 22 may be calculated from the change in the positional relationship and predicted and notified. Further, the warning may be canceled when the comparison distance is longer than the reference value twice in succession, and the number of times may be varied. The output means is not limited to the display of the warning messages 23 and 23A, but may be other output means as long as it can notify the user such as voice or mail transmission.

  Further, in the above-described embodiment, the case where the heavy rain occurrence area is the warning area 22 has been described. However, the present invention is not limited to this, and various events such as strong winds, tornadoes, typhoons, earthquakes, tsunamis, fires, and volcanoes are generated. It is good also considering a region and possibility region as a warning area.

In the above-described embodiment, the information immediately before the information for calculating the distance for comparison (information received last time) is used for the calculation of the reference value in order to improve the accuracy. May be.
Furthermore, the shortest distance is calculated and compared when calculating each distance. However, the present invention is not limited to this. For example, the number of distances shorter than a predetermined distance may be calculated.
Further, in the processing procedure (part 2), the positional relationship between the own aircraft position 21B after the lapse of the predetermined time and the warning area 22 is predicted. However, the present invention is not limited to this, for example, the entire route 24 is targeted. It is also possible to predict the position relationship with the alert area 22 by predicting all of the own device positions 21 on the route 24 at the reception timing.

  As described above, the information processing apparatus and the computer program according to the present invention have the effect of being able to easily grasp the positional relationship with the warning area that varies with the passage of time, and represent the position of the own apparatus. It is useful as an information processing apparatus and computer program that can acquire position information.
