Therefore, the brightness of the walking path throughout the year will be important data for choosing a new home. In addition, not only for pedestrians but also for car drivers, the brightness of the walking path throughout the year will be important data for choosing a new home. When there are multiple candidate routes from the destination to the new home, if the brightness of each candidate route can be grasped, it will be easier for real estate agents to introduce properties that meet the needs of customers, not just those looking for new homes Will. In calculating the value of real estate, the brightness of the route to the real estate will be an important indicator.

The network 1 is a computer network such as the Internet. A server 20 and a plurality of terminal devices 10 are connected via the network 1. The terminal device 10 may be a wireless terminal 10a such as a smartphone or a tablet terminal, or may be a wired terminal 10b such as a personal computer. When the matters common to the wireless terminal 10a and the wired terminal 10b are described, these are simply referred to as the terminal device 10.

  The receiving facility 30 has a receiver that receives an image taken by an artificial satellite 31 or the like. The reception facility 30 and the artificial satellite 31 are not essential for the information processing system 100. This is because the information processing system 100 can provide a navigation service if the satellite image is available. The server 20 accumulates ground images (hereinafter referred to as satellite images) taken from the sky by an artificial satellite 31 or an aircraft. The terminal device 10 transmits a search request including the departure place and the destination to the server 20. The server 20 has map data, performs a search in response to a search request from the terminal device 10, and transmits information indicating a plurality of candidate routes to the terminal device 10. In particular, in this embodiment, the server 20 searches and extracts a plurality of satellite images taken at night for an area including a plurality of candidate routes, compares the brightness of the plurality of candidate routes, and determines a recommended route. To the terminal device 10. Note that a route from a plurality of departure points to a single candidate location may be searched, or a route from a single candidate location to a plurality of destinations may be searched. For example, the address of the first new house candidate and the address of the second new house candidate may be input as the departure place, and the station name of the nearest station may be input as the target value. This will allow multiple new house candidates to be evaluated in terms of distance from the route, travel time, and nighttime brightness. As described above, the plurality of candidate routes include not only a plurality of routes between a single starting point and a single destination but also a starting point when there are a plurality of starting points and destinations. It may be a plurality of routes for each combination of destination and destination.

  FIG. 2 is a block diagram illustrating an example of hardware applicable to an information processing device such as the server 20 and the terminal device 10. The CPU 51 is an arithmetic device that executes various calculations according to a control program. The storage device 52 is a storage device such as a ROM, RAM, HDD (hard disk drive), or SSD (silicon state drive). The storage device 52 stores a boot program, data, a navigation program, and the like. In particular, the storage device 52 stores map data, satellite images, and the like. The communication interface 57 is a communication circuit that transmits and receives information to and from other information processing apparatuses via the network 1. The input device 55 is a keyboard, a mouse, a touch panel, or the like. An operator operates the input device 55 of the terminal device 10 to set a departure point and a destination, and a search request is transmitted to the server 20. The display device 56 is a display device such as a CRT (inter-cathode tube) display or a liquid crystal display. The display device 56 of the terminal device 10 displays the recommended route received from the server 20.

  FIG. 3 shows a part of functions realized by the CPU 51 of the server 20 executing the navigation program and a part of functions realized by the CPU 51 of the terminal apparatus 10 executing the program (for example, Web browser). The server 20 includes a map database 61 that stores map information, an image database 62 that stores satellite images (image data), and a route search unit 63 that searches for candidate routes and recommended routes. The recommended route is a candidate route having a relatively high evaluation value (eg, distance, travel time, nighttime brightness) among a plurality of candidate routes.

  The map database 61 may be a map database server that searches for one or more candidate routes from a departure place to a destination. The image database 62 may be an image database server that stores a plurality of images taken from above in a plurality of regions and each having a different time or date. The terminal device 10 includes a route presentation unit 64 that requests the server 20 to search for a route whose brightness is to be checked, and presents the candidate route and the recommended route received from the server 20 to the user. The server 20 may provide the navigation service as a web-based service. In this case, the route search unit 63 transmits a web page (HTML file, image data, script, etc.) for the operator to input the departure point and destination to the terminal device 10. The route presentation unit 64 of the terminal device 10 displays the web page on the display device 56. The Web page is provided with a text box for inputting a departure point, a text box for inputting a destination, and a search button for instructing a search.

<Flowchart>
FIG. 4 is a flowchart showing an example of route determination processing executed by the route search unit 63. The route presentation unit 64 of the terminal device 10 may receive the map data of the area including the input address from the route search unit 63 and display it on the display device 56 by inputting an address or the like. FIG. 5 shows an example of the map data 71. Instead of the map data 71, satellite images (eg, high-accuracy and high-resolution satellite photographs and aerial photographs) may be displayed.

  In S <b> 1, the route search unit 63 receives a search request including the departure place and the destination from the route presentation unit 64. FIG. 6 shows an example of the departure point 73 and the destination 74 set by the route presentation unit 64 for the map data 71. The starting point 73 and the destination 74 may be specified by inputting an address in a text box, or may be specified by touching or clicking the map data 71 displayed on the display device 56 through the input device 55. Good. The operator designates a departure point (eg, home) to a destination (eg, nearest station or bus stop) in order to examine the route in the walking section of the commuting route or school route. The operator may designate a candidate place where the new house is to be set as a departure place or a purpose. The present embodiment may be used to input the current address and the candidate location alternately or simultaneously to check the brightness of each route. In general, a route search from a single departure point to a single destination is executed, but in this embodiment, a route search from a plurality of departure points to a single destination may be executed. A route search from a single departure point to a plurality of destinations may be performed. This makes it easier for the operator to weigh the current address route and the new candidate address route. FIG. 13A shows a user interface 150a for executing a route search from a plurality of departure points to a single destination. FIG. 13B shows a user interface 150b for executing a route search from a single departure place to a plurality of destinations. As described above, the route search unit 63 functions as a reception unit that receives designations of a plurality of departure points and a single destination, and a reception unit that receives designations of a single departure point and a plurality of destinations.

  In S <b> 2, the route search unit 63 extracts one or a plurality of candidate routes that connect the departure point and the destination specified by the route presentation unit 64 by searching the map database 61. FIG. 7 is a diagram illustrating an example of a candidate route. The search result 72 includes a first candidate route 75 and a second candidate route 76. Actually, three or more candidate routes may be extracted.

  In S3, the route search unit 63 searches the image database 62 based on the candidate route, and extracts a plurality of satellite images for the area including the candidate route. Note that the plurality of satellite images include at least those captured at night. A satellite photograph with a resolution of 2 m or less will be able to determine the brightness (eg, illuminance) with high accuracy even on a walking path where pedestrians pass. Note that the present invention may be used not only for searching a route for a sidewalk but also for searching a route for a bicycle-only road, or for searching a route for an automobile road.

  When a plurality of candidate routes spans a plurality of images (such as satellite photographs), the route search unit 63 may perform illuminance correction (this process may be referred to as normalization or normalization). ). In this case, the route search unit 63 acquires a single wide image (small-scale image) including all of the plurality of candidate routes from the map database 61, and average illuminance (luminance) in an area including all candidate routes. Ask for. Further, the route search unit 63 obtains a ratio (illuminance ratio) between the average illuminance and the illuminance of each geographical area. The geographical area is an area that is divided into a plurality of areas and is covered by a plurality of images with a large scale. The route search unit 63 corrects the illuminance of each image by multiplying each of the plurality of large scale images by the illuminance ratio obtained from the wide image for each image.

  By the way, the plurality of satellite images extracted in S3 may be a plurality of satellite images having different times and dates / times, such as a plurality of satellite images periodically taken at night in each region. This will allow us to identify the lowest illuminance throughout the year in the region that is independent of season, weather, and time. There are cases where navigation services are used for short-term purposes and cases where they are used for long-term purposes. The former is a general navigation service, while the latter is a service used for selecting a new house. Therefore, the lowest illumination throughout the year will be useful for real estate related services. A satellite image taken in rainy weather may be an image in which the brightness on the ground cannot be determined by clouds. Such satellite images are excluded in advance.

  In S4, the route search unit 63 divides the extracted satellite image into a plurality of regions, and obtains the illuminance of each region. FIG. 8 can be said by combining the first satellite image 81 taken at the first date and time, the second satellite image 82 taken at the second date and time, the first satellite image 81 and the second satellite image 82. FIG. 6 is a diagram showing a composite image 83. The route search unit 63 divides the satellite image into N × M areas and adds the luminance of the pixels constituting each area to obtain the illuminance of each area. As can be seen by comparing the first satellite image 81 and the second satellite image 82, the illuminance of each region is different if the shooting date and time are different. For example, when a car passes by the shooting date and time, the illuminance is increased by the headlight of the car. Since cars are not always in traffic, pedestrians may not rely on car headlights for safety. Therefore, when determining the illuminance in each section of the candidate route, it will be necessary to exclude the influence of the automobile headlight. This will be realized by obtaining the minimum illuminance for each region from a plurality of satellite images. The size of each region may be a size about the width of the sidewalk.

  In S5, the route search unit 63 compares a plurality of satellite images and determines the minimum illuminance in the same region. For example, the route search unit 63 extracts regions having the same latitude and longitude from a plurality of satellite images, compares the illuminances of the extracted regions, and determines the minimum illuminance. The route search unit 63 may create the composite image 83 by mapping the minimum illuminance of each coordinate (each region). As a result, the minimum illuminance of each region is determined in a predetermined period. In order to reduce the calculation load, the minimum illuminance may be determined only for the region on the candidate route.

  In S6, the route search unit 63 determines an evaluation value of each candidate route based on at least the minimum illuminance, and determines a candidate route having the highest evaluation value as a recommended route. The evaluation value may take into account the distance and travel time (walking time, etc.) of each candidate route. For example, illuminance, distance, and travel time may be evaluated in 10 stages, and the total score may be used as the evaluation value. For example, the evaluation value increases in proportion to the illuminance, the evaluation value increases in inverse proportion to the distance, and the evaluation value increases in inverse proportion to the travel time. The route search unit 63 compares the evaluation values of a plurality of candidate routes, and determines the candidate route having the highest evaluation value as the recommended route. It should be noted that the parameters to be considered in the evaluation value may be designated in advance by the operator. For example, only the illuminance may be included in the evaluation value so that the illuminance has the highest priority, or weighting may be introduced.

In S <b> 7, the route search unit 63 outputs the recommended route to the terminal device 10 in association with the illuminance. The route presentation unit 64 of the terminal device 10 causes the display device 56 to display the received recommended route.
The route search unit 63 may output a plurality of candidate routes / recommended routes to the terminal device 10 in association with the illuminance obtained in S4. At this time, the processes of S5 and S6 are omitted.

  FIG. 9 shows an example of a user interface 77 for presenting a recommended route. In the user interface 77, the first candidate route 75 and the second candidate route 76 are mapped and displayed on the map data acquired from the map database. The minimum illuminance of each section may be visualized by changing the color or luminance of each section of the first candidate route 75 and the second candidate route 76 according to the minimum illuminance. As a result, the operator can easily recognize the minimum illuminance of each section. In this example, since the second candidate route 76 is a recommended route recommended over the first candidate route 75, the second candidate route 76 may be highlighted. For example, the second candidate route 76 may be displayed blinking or may be displayed with a thicker line.

  FIG. 10 shows another example of a user interface 77 for presenting a recommended route. In the user interface 77, the first candidate route 75 and the second candidate route 76 are mapped and displayed on the composite image created based on the minimum illuminance. As a result, the operator can easily recognize the minimum illuminance of each section.

  FIG. 11 is a diagram illustrating an example of a user interface including an illuminance graph 85 of each candidate route. A graph 85 indicating a change in luminance may be displayed on the display device 56 together with the interface including the map shown in FIG. 9 or 10. In the graph 85, the horizontal axis that is the first axis indicates the distance of each candidate route, and the vertical axis that is the second axis indicates the brightness (illuminance).

  The first luminance curve 86 shows the relationship between the distance from the departure point and the illuminance for the first candidate route 75. The second luminance curve 87 shows the relationship between the distance from the departure point and the illuminance for the second candidate route 76. Comparing the first luminance curve 86 and the second luminance curve 87, it can be seen that the second candidate route 76 has a longer travel distance than the first candidate route 75, but most of the sections are bright. On the other hand, although the first candidate route 75 has a short moving distance, it can be seen that there are many dark sections.

  Note that the route search unit 63 may present statistical values such as the average value, maximum value, and minimum value of the illuminance of each candidate route to the route presentation unit 64. The route presentation unit 64 associates and outputs these statistical values for candidate routes and recommended routes. Note that the route and the statistical value may be displayed simultaneously or individually.

It functions as brightness determination means for determining (minimum illumination). The determination unit 120 may function as a brightness determination unit that divides an image into a plurality of image areas and determines the brightness (eg, luminance and illuminance) of each image area.

  As described with respect to S5, the determination unit 120 determines the latitude and longitude coordinates for the plurality of image regions constituting the first satellite image and the plurality of image regions constituting the second satellite image acquired for each candidate route. Image regions that match may be extracted. The comparison unit 122 may compare the brightness of the image area extracted from the first satellite image with the brightness of the image area extracted from the second satellite image. The selection unit 131 may select a darker image region based on the comparison result of the comparison unit 122. The synthesizing unit 132 may function as a generating unit that synthesizes the image areas selected for each coordinate to generate one synthesized image.
