4 is a time series illustrating a method of providing distance view information according to an embodiment of the present invention. Hereinafter, a method, a system, and a computer program of providing distance view information of the present invention will be described in detail with reference to FIGS. 3 and 4.

The street view function provided by the electronic map is characterized by providing a photograph of the real world. Therefore, in order to provide the street view function, actual photographing is required. In general, a road view is obtained by moving a road on a car and taking a 360-degree panoramic image at regular intervals with a camera installed on the car. That is, when a location where the street view picture is taken is referred to as a street view spot, when the user selects the street view spot on the map, a panorama image taken by the corresponding street view spot is provided as the street view picture. However, the distance view picture is different from the actual street appearance after a certain time after the shooting, and therefore, there is a need to update the distance view picture after a certain time.

On the other hand, there are regions in which the street view photographs need to be updated frequently, or regions in which the need for updating is relatively low according to the characteristics of the region. For example, in the case of a road inside an apartment complex, the location, type, and appearance of a building taken on a street view photograph does not change after several years, so the need for updating is low. However, in the case of the roadside, there is a need to update frequently because the location, shape, and shops in the building are changed frequently. Despite these regional features, collectively capturing and updating street view photos for all regions on the map can lead to costly and time-consuming inefficiencies.

An object of the present invention is to establish a distance view photographing plan in consideration of the point of time difference with other comparative data for each region, the number of times of viewing and the elapsed time from the point of view when taking a street view photograph in consideration of the above-described point do.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 3 and 4.

First, the evaluation unit determiner 310 determines an evaluation unit corresponding to a link connecting one region on the electronic map or two or more points on the electronic map (S1). The evaluation unit may be a basic unit for calculating a comparison score, a popularity score, and an aging score described later.

According to an embodiment of the present invention, all points, lines, or surfaces on the electronic map may be evaluation units. For example, there may be an evaluation unit corresponding to one area (point or surface) or a link (line) connecting two or more points on the electronic map. In a more specific example, the evaluation unit is a point on a map such as a street view spot where a street view photograph was taken, an area within a predetermined radius based on a specific point, or a predetermined area designated as an administrative unit, and two points on a road. The connecting line may be an evaluation unit. According to an embodiment of the present invention, a score for calculating a comparison score based on a distance view shooting time difference with comparison data, a popularity score based on the number of distance view requests by users, and an aging score based on the elapsed shooting date for each evaluation unit, may be calculated as scores. Can be. Alternatively, in the following description, calculating the comparison score, the popularity score, the aging score, or the comprehensive score for the evaluation unit may be calculated by sampling data of some distance view spots among the street view spots belonging to the evaluation unit.

More specifically, if the evaluation unit is a face, in particular, an area within a predetermined radius from a specific coordinate on the map, a comparison score, a popularity score, and an aging score, which will be described later, may be calculated for the street view spots within the evaluation unit. . In this case, specific coordinates may correspond to individual distance view spots, and the evaluation unit may be an area within a predetermined radius from the individual distance view spots. Alternatively, the specific coordinates may refer to the center coordinates of the administrative region (eg, the east unit), and the evaluation unit may be the administrative region including the central coordinate.

In another example, when the evaluation unit is a link connecting two points on the road, a comparison score, a popularity score, and an aging score, which are described below, may be calculated for the street view spots existing on the link. In this case, the point on the map that is the basis of the link may be a street view spot on the road, but is not necessarily limited thereto. Or, the point on the map on which the link is based may be an intersection on the road, and one link may be a line on the road segmented by the intersection. In other words, a link may be a line on a road connecting a specific intersection to the next intersection. However, the present invention is not limited thereto, and there may be a link including a plurality of intersections. That is, a line of a road segmented into an intersection, a part of the road without an intersection, a part of a road including an intersection, and the like may all be links of the present invention.

The evaluation unit may be a basic unit for calculating a comparison score, popularity score, or aging score, which will be described later. In this case, when there are a plurality of street view spots in the evaluation unit, the average or sum of the scores of the corresponding street view spots may be the score for each evaluation unit. For example, when the evaluation unit is a specific area on the map, the average score or the sum of the popularity scores of the plurality of street view spots existing in the specific area may be the popularity score of the corresponding evaluation unit. In addition, when the evaluation unit is a link on a road, the average or sum of the aging scores of the plurality of street view spots existing on the link may be the aging score of the corresponding evaluation unit.

Next, at least one of a comparison score for each evaluation unit by the comparison score calculation unit 320, a popularity score by the popularity score calculation unit 330, or an aging degree score calculation unit 340 is calculated. (S2).

In more detail, the comparison score calculation unit 320 may calculate a comparison score for each evaluation unit. The comparison score is a score indicating how long the photographing time point of the target data has elapsed compared to the photographing time point of the comparison data for each evaluation unit. The comparison score calculation unit 320 obtains a distance view photographing time point of the comparison data of the distance view spots corresponding to the evaluation unit, and obtains a distance view photographing time point of the target data, and calculates two distance view photographing points in order to calculate a comparison score. The comparison score for each evaluation unit is calculated based on the time difference of.

According to an embodiment of the present invention, the comparison data may be competitor's most recent distance view photographing data, and the target data may be its most recent distance view photographing data. For example, when the latest photographing time of the comparison data for the specific evaluation unit is January 1, 2016, and the most recent photographing time of the target data is January 1, 2017, the photographing time difference may be +365 days. Conversely, when the latest photographing time of the comparison data for the specific evaluation unit is January 1, 2017, and the most recent photographing time of the target data is January 1, 2016, the time difference of the specific evaluation unit may be -365. Based on this time difference, the comparison score for each evaluation unit can be calculated by normalizing the time difference.

According to an embodiment of the present invention, the higher the comparison score, the more recently the photographing of the target data is performed than the photographing time point of the comparison data. That is, as the comparison score is higher, the distance view photographing date of the competitor is more recent than the competitor's distance view photographing date for the evaluation unit, and thus, the distance view data of the competitor may be judged to be more competitive.

In addition, the comparison score calculation unit 320 may visualize and provide a comparison score for each evaluation unit on a map. In this case, the comparison score calculation unit 320 may visualize the comparison score for each evaluation unit so that the user intuitively recognizes the comparison score for each evaluation unit by overlaying and displaying symbols and text such as figures and lines on the map. In this case, the comparison score calculator 320 may integrate and provide the visualized symbols according to the accumulation of the electronic map. For example, as the scale of the map changes, adjacent visualized symbols can be integrated or provided separately.

5 is an example of visualizing a comparison score according to an embodiment of the present invention.

Referring to FIG. 5, a map visualizing a comparison score according to an embodiment of the present invention is displayed. In more detail, in the embodiment of FIG. 5, the evaluation unit is one area on the map, and a comparison score calculated for each evaluation unit is shown according to the degree of shading in the circle symbol. That is, the darker the degree of shadow, the smaller the comparison score, and the lighter the degree of shadow, the higher the comparison score. More specifically, circle a1 is shaded darker than circle a2, and the user views the visualized data, and the evaluation unit corresponding to the corresponding a1 point has a higher shooting point than the competitor's distance view shooting data than the evaluation unit corresponding to the a2 point. You can see that it has fallen behind.

In addition, the setting menus m51 to m55 may exist in the map visualizing the comparison score of FIG. 5. In more detail, the comparison date selection menu m51 may select a date for calculating a comparison score. In the visualization sharpness menu m52, the transparency of the visualization symbol (circle symbol in the embodiment of FIG. 5) overlaid on the map may be adjusted. In addition, in the comparison step menu (m53) may determine how many steps to express the comparison score in the shade or color of the visualization symbol, and what color or shade to express. Also, in the comparison date menu m54, the maximum and minimum values of the difference value daydff of the photographing date of the comparison data and the photographing date of the target data may be determined. In addition, the magnification information m55 may display the magnification of the displayed map.

In addition, in the embodiment of FIG. 5, when one of the circle symbols on the map is selected, a specific value for the difference value daydff of the photographing date may be displayed on the auxiliary window m56. In more detail, when A is the last photographing date of the comparison data, and B is the last photographing date of the target data, it can be seen that the difference value daydff of the photographing date is 1321. This may mean that the company's distance view shooting date is 1321 days later than the competitor's distance view shooting date of the evaluation unit corresponding to the circle symbol.

According to an embodiment of the present invention, the visualization data of the embodiment as shown in FIG. 5 may intuitively provide information on which area of the street view was taken earlier or later than the competitor, and how quickly or lately. A street view photographing plan can be established with reference. For example, a street view photographing plan may be designed to preferentially update street view photographs of regions having a low comparison score (such as an a3 area on a map) having a lower comparison score (prior to a competitor's shooting date).

6 is another example of visualizing a comparison score according to an embodiment of the present invention.

6 illustrates a map visualizing a comparison score according to an embodiment of the present invention. 6 is an example in which the scale of the map is increased. When the scale is increased as shown in FIG. 6, when the circle symbol is displayed for each of the same evaluation units as in FIG. 5, the number of circle symbols to be displayed on the map may be excessively increased, thereby not providing meaningful information to the user. Therefore, in the map of which the scale is increased as shown in FIG. 6, the comparison score may be displayed as a circle symbol for each enlarged evaluation unit by expanding the range of the evaluation unit.

That is, the range of the area of the evaluation unit of FIG. 6 may be larger than the evaluation unit of FIG. 5. That is, the range of the area of the evaluation unit is also small in the small-scale map as shown in FIG. 5, but the area of the evaluation unit may also be large in the large-scale map as shown in FIG. 6. That is, since FIG. 6 calculates a comparison score for each evaluation unit by averaging or summing the comparison scores of the distance view spots in the wider evaluation unit, the user zooms out the comparison score visualization map as shown in FIG. Visually recognize whether the comparison score is low. In addition, since the evaluation unit can be enlarged or reduced as shown in FIG. 5 and FIG. 6, after establishing an approximate distance view photographing plan with reference to the enlarged evaluation unit, the detail can be described with reference to the reduced evaluation unit. Plan a street view plan.

Next, the popularity score calculation unit 330 calculates a popularity score for each evaluation unit according to an embodiment of the present invention. The popularity score may be determined by how many street view viewing requests were made at the street view spot corresponding to the evaluation unit. For example, when the evaluation unit is a link, the popularity score calculation unit may calculate the popularity for each link based on how many users request a street view of a road corresponding to the link. To this end, the popularity score calculation unit 330 may have street view request data of users for each street view spot. In one example, the popularity score calculation unit 330 may calculate the popularity score by summing or averaging the number of street view requests of the street view spots existing in the evaluation unit based on the street view request data of the users for each street view spot. have. In addition, the popularity score calculation unit 330 may calculate the popularity score for each evaluation unit by normalizing the number of viewing distance view requests for each evaluation unit.

In addition, the popularity score calculation unit 330 may visualize and provide a popularity score for each evaluation unit. As described in the description of the comparison score calculation unit 320, the popularity calculation unit 330 may display the popularity score for each evaluation unit as a symbol or text on an electronic map and provide the user with intuitive visual information. Although the embodiments of FIGS. 5-6 relate to comparison scores, in other embodiments of the present invention may be used to visualize and provide the calculated popularity scores. For another example, when the evaluation unit is a link, the link corresponding to the road on the electronic map may be displayed as a symbol, the popularity score may be written as text, and the shadow of the link may be differently expressed according to the popularity score.

7 is an example of visualizing a popularity score according to an embodiment of the present invention.

Referring to FIG. 7, links may be displayed on the electronic map by being overlaid with a line symbol (eg, l1, l2, l3, etc.) on a corresponding road. The embodiment of FIG. 7 illustrates that the evaluation unit is a link, and a region of a road composed of one line connecting two points on the road may constitute one link. More specifically, in the embodiment of FIG. 7, the area l1 of the road segmented into the intersection, the partial area l2 of the road without the intersection but the area l3 of the road including the intersection, and the like all constitute a link. Can be. In addition, the link may not exist on the road where the street view spot does not exist.

When the evaluation unit is a link as shown in FIG. 7, the popularity score calculation unit 330 may calculate the popularity score for each link by obtaining the number of distance view requests of users of the street view spots existing in the link. More specifically, the number of street view requests existing in the link may be normalized by averaging or summing the number of street view requests, and then calculating a popularity score. In addition, as shown in FIG. 7, the popularity score for each link may be displayed as text, and the color of the corresponding link may be changed or shaded according to the popularity score. For example, the popularity score of the link l2 may be 49.1, which is higher than the popularity score of the link l1, 36.8, and the shadow of l2 may be darker than the link l1. Through this, it is possible to provide visual information on the popularity of each link, and to establish a shooting plan that preferentially updates the street view photo of the road including the more popular link.

In addition, setting menus m71 to m75 may exist in a map visualizing the popularity score of FIG. 7. In more detail, the visualization sharpness menu m71 may adjust the transparency of the visualization information (line symbol and text in the embodiment of FIG. 7) overlaid on the map. In addition, the comparison step menu m72 may determine how many steps to express different visualization scores in the shade or color of the visualization symbol, and what color or shade to express. In addition, the date filter m74 may set a date range for collecting the number of street view requests of users to calculate the popularity score. In addition, the magnification information m75 may display the magnification of the displayed map.

Next, the aged score calculation unit 340 calculates the aged score for each evaluation unit according to an embodiment of the present invention. The deterioration score is a score indicating how much time has elapsed since the most recent distance view photographing date, and according to an embodiment of the present invention, the average or sum of the distance view photographing elapsed times of the street view spots corresponding to the evaluation unit according to an embodiment of the present invention. The score can then be normalized. According to an embodiment of the present invention, the lower the aging score, the corresponding evaluation unit may have elapsed time since the last photographing.

In addition, the aged score calculation unit 340 may also visualize the aged score. Although the embodiments of FIGS. 5-7 relate to comparison scores and popularity scores, in other embodiments of the present invention may be used to visualize and provide the calculated aging scores. That is, the aged scores may be calculated for each evaluation unit consisting of areas or links, and may be expressed in symbols or text so as to be visually recognized on the map.

Next, the comprehensive score calculation unit 350 may calculate a comprehensive score for each evaluation unit based on at least one of a comparison score, a popularity score, and an aging score for each evaluation unit calculated according to an embodiment of the present invention ( S3).

The comprehensive score according to an embodiment of the present invention may be any one of a comparison score, a popularity score, or an aging score, but may be a score obtained by combining two or more of the above-described scores. For example, the comprehensive score may be a comparison score and a popularity score, or a score including a comparison score and an aging score, a popularity score and an aging score, or a combination of the comparison score, the popularity score, and the aging score.

According to an embodiment of the present invention, the comprehensive score calculation unit 350 may vary the reflection ratio of each score when calculating the comprehensive score. For example, when the comprehensive score is a combination of the popularity score and the aging score, the popularity score may be reflected at a ratio of 0.7 and the aging score at a ratio of 0.3. In this way, when calculating the comprehensive score, by varying the ratio reflecting each score, the comprehensive score reflecting the characteristics of each region or road can be calculated.

In one embodiment of the present invention, the comprehensive score calculation unit 350 increases the ratio reflecting the popularity score in the region of high popularity score, and increases the ratio reflecting the aging score in the region of low aging score. Can be increased. In other words, in areas with many floating populations and shops or areas with high popularity scores, the ratio of reflecting the popularity scores can be increased to preferentially photograph streets with high popularity rather than the aging degree of street view photography. On the contrary, in areas with little floating population or low aging scores, such as roads in apartment complexes, it is possible to preferentially photograph old streets by increasing the reflecting ratio of aging scores rather than popularity. According to an embodiment of the present invention, by varying the ratio of combining the scores in consideration of the characteristics of the area, it is possible to more effectively calculate the overall score to plan the street view shooting.

In addition, the comprehensive score calculation unit 350 may visualize the calculated comprehensive score on the electronic map (S4). The above-described method for visualizing the comparison score, the popularity score, and the aging score may be equally applied to the method for visualizing the comprehensive score. More specifically, although the embodiments of FIGS. 5-7 relate to comparison scores and popularity scores, in other embodiments of the present invention may be used to visualize and provide the calculated composite score. That is, a comprehensive score may be calculated for each evaluation unit, and may be expressed in a symbol or text so as to be visually recognized on the map.

8 is an example of visualizing a comprehensive score according to an embodiment of the present invention.

Referring to FIG. 8, an example of visualizing a comprehensive score calculated by the comprehensive score calculator 370 is illustrated. FIG. 8 is a variation of FIG. 7, in which a symbol visualizing a composite score combining a popularity score and an aging score is shown. In this case, the same map as in FIG. 7 is represented, but a shade of a line symbol representing a link is expressed according to the composite score. And that the text has changed. The user may adjust the ratio reflecting the popularity score and the aging score among the comprehensive scores by using the score ratio adjustment menu m81. Referring to FIGS. 7 and 8, it can be seen that the link l1 has a popularity score of 36.8, but the combined score of the link l1 reflecting a popularity score of 70% and an aging score of 30% is 29.5. In addition, with regard to links l1 and l2, the link l1 score is high when only the popularity score is considered, and the overall score considering link popularity and aging is high because the score of the link l2 is high. It can be seen that the road corresponding to the photographing should be made first.

Next, the photographing plan planning unit 360 establishes and visualizes a photographing plan based on the calculated comprehensive score (S5). In more detail, the photographing planner 360 may establish a photographing plan to preferentially photograph a coordinate or a link having a low comprehensive score. As described above, the comprehensive score is one of two or more of the comparison scores, popularity scores, and aging scores for each evaluation unit. Frequent updates are required, or it can be seen that the time has elapsed since the shooting date. Therefore, the photographing plan establishment unit 360 may design a photographing path to preferentially photograph a path having a low total score when establishing a photographing plan in consideration of the comprehensive score. In addition, the photographing plan established by the photographing planner 360 may be visualized on a map so that the user may easily grasp.

For example, in the embodiment in which the comprehensive score is a combination of the popularity score and the aging score, as in the embodiment of FIG. 8, the photographing planner determines the photographing plan so as to first obtain a street view photograph of a road corresponding to a link having a low score. Can be established. In addition to the embodiment as shown in FIG. 8, when the evaluation unit is an area, a shooting plan may be established to preferentially photograph a street view photograph of a road in an area having a low total score. In addition, although not shown, the established photographing plan may be visualized on the map by a symbol such as an arrow.
