DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate explanations will be omitted. Furthermore, the embodiments of the present disclosure in the following description are specific examples of the present invention, and the present invention is not limited to these embodiments unless otherwise specified to limit the present invention.

[0011] FIG. 1 is a diagram showing an example of a system configuration of an infrastructure impact calculation system 4 including an infrastructure impact calculation device 1 according to an embodiment. As shown in FIG. 1, the infrastructure impact calculation system 4 includes the infrastructure impact calculation device 1, one or more vehicles 2 (plurality of vehicles 2 will be collectively referred to as "vehicles 2" as appropriate), and one or more external devices 3 (plurality of external devices 3 will be collectively referred to as "external devices 3" as appropriate). The infrastructure impact calculation device 1 and the vehicles 2 are communicatively connected to each other via a network such as a mobile communication network, and can transmit and receive information to and from each other. The infrastructure impact calculation device 1 and the external devices 3 are communicatively connected to each other via a network such as the Internet, and can transmit and receive information to and from each other.

[0012] The infrastructure impact calculation device 1 is a server device that calculates an infrastructure impact, which is the degree of impact of construction work on road infrastructure. In this embodiment, the construction work is assumed to be road construction, but is not limited thereto and may be general civil engineering or construction work. The road infrastructure is infrastructure laid under, above, or around (near, near, nearby, nearby, around, around, beside, beside, within a predetermined distance from) the road. Examples of road infrastructure include water pipes (water pipes, sewer pipes), gas pipes, electric wires, or communication lines buried under the road, electric wires or communication lines strung on telephone poles above the road, or water pipes, gas pipes, electric wires, communication lines, or railroad tracks laid beside or next to the road. The impact degree is the degree of impact. The impact degree may be expressed, for example, as an integer between "0" and "100," with values ​​closer to "0" indicating less impact and values ​​closer to "100" indicating greater impact. The impact may be expressed as a probability, a real number, or a discrete value such as "large," "medium," or "small," but is not limited to these. Details of the infrastructure impact calculation device 1 will be described later.

[0013] The vehicle 2 is a general vehicle with wheels. In this embodiment, a car traveling on a road owned by a user of the infrastructure impact calculation device 1 is assumed, but this is not limited to this. The vehicle 2 is equipped with a drive recorder, a dashcam D. The dashcam D is a video camera (imaging device) attached to the windshield or dashboard of the vehicle 2. The dashcam D captures images of the road outside the vehicle and outputs the images as road images. In this embodiment, the term "image" may be replaced with "video," "video," or "moving image" as appropriate. The vehicle 2 transmits the road images captured by the dashcam D (images of the road) to the infrastructure impact calculation device 1 via a network at any timing or a predetermined timing.

[0014] The drive recorder D may be equipped with a GPS (Global Positioning System). The drive recorder D may use the equipped GPS to output imaging position information (latitude, longitude, etc.) relating to the position where the road image was captured (the position of the drive recorder D). The vehicle 2 may transmit the road image captured by the drive recorder D and the imaging position information (output by the drive recorder D) relating to the position where the road image was captured to the infrastructure impact calculation device 1 via the network at any timing or a predetermined timing.

[0015] The external device 3 is an external server device (with respect to the infrastructure impact calculation device 1). The external device 3 stores various information used in the processing of the infrastructure impact calculation device 1 in advance and transmits (provides) it to the infrastructure impact calculation device 1 via a network. The external device 3 may transmit road infrastructure information related to road infrastructure to the infrastructure impact calculation device 1. The road infrastructure information may include at least one of the (preset) location (latitude, longitude, etc.) of the road infrastructure, its type, depth (under the road), height (above the road), and years of installation. The road infrastructure information makes it possible to grasp the buried (installed) status of the road infrastructure. The external device 3 may transmit construction information related to construction work to the infrastructure impact calculation device 1. The construction information may include at least one of information related to construction work that has been notified in advance to the company or local government that owns the infrastructure (notified construction work), the construction location (latitude, longitude, etc.), the waiting location (latitude, longitude, etc.) of construction personnel, and a weight according to the type of construction object (described later).

[0016] When there are multiple external devices 3, each external device 3 may store different types of information. The external devices 3 may be incorporated into the infrastructure impact calculation device 1. That is, the infrastructure impact calculation device 1 (the storage unit 10 described below) may store the above-mentioned various types of information in advance.

[0017] 2 is a diagram illustrating an example of a functional configuration of the infrastructure impact calculation device 1 according to the embodiment. As shown in FIG. 2, the infrastructure impact calculation device 1 includes a storage unit 10, an acquisition unit 11 (acquisition unit), an extraction unit 12 (extraction unit), a calculation unit 13 (calculation unit), and a display unit 14 (display unit).

[0018] Each functional block of the infrastructure impact calculation device 1 is assumed to function within the infrastructure impact calculation device 1, but is not limited to this. For example, some of the functional blocks of the infrastructure impact calculation device 1 may function in a computer device different from the infrastructure impact calculation device 1, and connected to the infrastructure impact calculation device 1 through a network, while appropriately sending and receiving information with the infrastructure impact calculation device 1. Furthermore, some functional blocks of the infrastructure impact calculation device 1 may be omitted, multiple functional blocks may be integrated into one functional block, or one functional block may be separated into multiple functional blocks.

[0019] Hereinafter, each function of the infrastructure impact calculation device 1 shown in FIG. 2 will be described.

[0020] The storage unit 10 stores any information used in calculations in the infrastructure impact calculation device 1 and the results of calculations in the infrastructure impact calculation device 1. The information stored by the storage unit 10 may be referred to by each function of the infrastructure impact calculation device 1 as appropriate.

[0021] The acquisition unit 11 acquires road images captured on a road. The acquisition unit 11 may acquire road images captured by a dashcam D (in the vehicle 2). The acquisition unit 11 may further acquire imaging position information relating to the position where the road image was captured.

[0022] Specifically, the acquisition unit 11 acquires, via a network, at least one of a road image captured by the drive recorder D of the vehicle 2 and transmitted from the vehicle 2, and imaging position information (output by the drive recorder D) relating to the position where the road image was captured. If there are multiple vehicles 2, the acquisition unit 11 may acquire at least one of the road image and the imaging position information from each of the vehicles 2. The acquisition unit 11 may acquire at least one of the road image and the imaging position information stored by the storage unit 10 (not from the vehicle 2). The acquisition unit 11 may acquire at least one of the road image and the imaging position information from another device (not from the vehicle 2) via a network or the like.

[0023] The acquisition unit 11 may acquire various types of information from the external device 3 via a network. For example, the acquisition unit 11 may acquire at least one of road infrastructure information and construction information from the external device 3. When there are multiple external devices 3, the acquisition unit 11 may acquire at least one of road infrastructure information and construction information from one or more of the external devices 3. The acquisition unit 11 may acquire at least one of road infrastructure information and construction information stored by the storage unit 10 (not from the external device 3).

[0024] The acquisition unit 11 may output the acquired information (road images, imaging location information, various information, road infrastructure information, construction information, etc.) to the extraction unit 12, the calculation unit 13, or the display unit 14, or may store it in the storage unit 10.

[0025] The extraction unit 12 extracts (recognizes) construction objects included in the road image acquired by the acquisition unit 11. A construction object is one or more objects (targets) related to construction (plural construction objects will be collectively referred to as "construction object" as appropriate). An object may be an object or a person. For example, construction objects may be cones (color cones (registered trademark)), cone bars, barricades, fences, arrow signs, (construction) signs, other construction items, excavators, cranes, other (construction) special vehicles, construction locations, waiting areas for construction workers, people wearing (construction) helmets, other construction workers, etc.

[0026] Specifically, the extraction unit 12 acquires the road image output from the acquisition unit 11 or the road image stored by the storage unit 10, and extracts construction objects from the acquired road image using an existing technology for extracting objects from images. For example, construction objects included in the road image may be extracted using a trained model that has been machine-learned in advance using images of construction objects. Alternatively, for example, after extracting any object from the road image using an open software library such as OpenCV, only the construction objects may be extracted using pattern matching technology or the like.

[0027] The extraction unit 12 may further extract relative position information regarding the relative position between the position where the road image was captured and the position of each construction object, based on the imaging position information acquired by the acquisition unit 11. Specifically, the extraction unit 12 acquires the road image and imaging position information output from the acquisition unit 11, or the road image and imaging position information stored by the storage unit 10, and extracts relative position information for the acquired road image using an existing technology for extracting the relative position of an object included in the image, based on the acquired imaging position information and the construction object extracted by the extraction unit 12. For example, the extraction unit 12 extracts (measures) the relative position between the position of the vehicle 2 (or the dashcam D) and the position of each construction object, using technology such as monocular depth estimation, SLAM (Simultaneous Location and Mapping), or SfM (Structure from Motion).

[0028] The extraction unit 12 may output the extraction result to the calculation unit 13 or the display unit 14, or may store it in the storage unit 10. The extraction result may be a set of pairs of information identifying a construction object, such as "[cone, (5.3m, -1.2m)], [barricade, (-4.7m, 3.8m)], ...", and relative position information, which is the relative coordinates between the construction object and the position where the road image was captured.

[0029] The calculation unit 13 calculates an infrastructure impact degree, which is the degree of impact of the construction work on the road infrastructure, based on the distance between the construction object and the road infrastructure. The calculation unit 13 may calculate the infrastructure impact degree based on the distance between the construction object extracted by the extraction unit 12 and the road infrastructure. The calculation unit 13 may calculate the distance between the construction object and the road infrastructure based on the imaging position information acquired by the acquisition unit 11, the relative position information extracted by the extraction unit 12, and information on the predetermined position of the road infrastructure (included in the road infrastructure information acquired by the acquisition unit 11 from the external device 3).

[0030] Fig. 3 is a diagram showing an example of the distance between a construction object and road infrastructure. In Fig. 3, a water pipe W, which is a part of road infrastructure, cones C1, C2, and C3, which are construction objects, a barricade B, which is a construction object, and an arrow A, which is a construction object, are included. The (shortest) distance between (the center line of) the water pipe W and the cone C1 is distance d C1 The distance between the water pipe W and the barricade B is d B The distance between the water pipe W and the cone C2 is d C2 The distance between the water pipe W and the cone C3 is d C3 The distance between the water pipe W and the arrow plate A is d A is shown.

[0031] The calculation unit 13 performs coordinate calculations and the like based on the extraction result output by the extraction unit 12 or the extraction result stored by the storage unit 10, the imaging position information output by the acquisition unit 11 or the imaging position information stored by the storage unit 10, and the road infrastructure information (or information related to the position of the road infrastructure) output by the acquisition unit 11 or the road infrastructure information (or information related to the position of the road infrastructure) stored by the storage unit 10, and calculates the above-mentioned distance d C1 , distance d B , distance d C2 , distance d C3 and distance d A Calculate.

[0032] The calculation unit 13 calculates the distance d between the construction object and the road infrastructure by the following formula (1): j (j is the index value of the construction object) may be used to calculate the infrastructure impact score. score=Σ(1 / d j ) …(1)

[0033] That is, the more construction objects there are, and the greater the distance d between the construction objects and the road infrastructure, j The closer (shorter) the time, the greater the impact on infrastructure.

[0034] The calculation unit 13 may calculate the infrastructure impact degree further based on the type of each construction object. More specifically, the calculation unit 13 may calculate the infrastructure impact degree by weighting the distance between the construction object and the road infrastructure according to the type of the construction object. FIG. 4 is an example of a table of weights according to the type of construction object. As shown in FIG. 4, special vehicles such as excavators and cranes are weighted higher than construction items such as signs and cones. Since construction items such as signs and cones are not dangerous to the road infrastructure, their weights can be set relatively low. On the other hand, special vehicles such as excavators and cranes may damage the road infrastructure, so their weights can be set relatively high. The weights according to the type of construction object may be acquired from the storage unit 10 where they are stored in advance, or may be acquired from construction information acquired by the acquisition unit 11 from the external device 3.

[0035] The calculation unit 13 calculates a weight w according to the type of each construction object using the following formula (2): i The infrastructure impact score may be calculated further based on (i is the index value of the type) (for equation (1)). score=ΣΣ(w i / d i,j ) …(2)

[0036] That is, the greater the weight according to the type of construction object, the greater the impact on infrastructure.

[0037] The calculation unit 13 may calculate the infrastructure impact level based on a distance (between a construction object and road infrastructure) that meets a predetermined standard. More specifically, the calculation unit 13 may calculate the infrastructure impact level based on a distance that is less than (or equal to or less than) a predetermined threshold. For example, if the distance between a construction object and road infrastructure is equal to or greater than the threshold δ, the calculation unit 13 ignores (sets to zero) the infrastructure impact level for the construction object. This reduces the amount of calculation when the construction object spans a wide area.

[0038] The calculation unit 13 may calculate the infrastructure impact degree further based on the depth or height of the road infrastructure. For example, the calculation unit 13 may set a weight according to the type of the above-mentioned construction object according to the depth of the road infrastructure. FIG. 5 is an example table of weights of construction objects according to the (burial) depth of the road infrastructure. As shown in FIG. 5, the shallower the road infrastructure, the greater the weight is set. For example, from the example table shown in FIG. 5, it can be seen that if the road infrastructure is shallow and there is a backhoe as a construction object, the weight is greater, i.e., the infrastructure impact degree is greater. That is, the calculation unit 13 uses the inverse of the depth of the road infrastructure as the weight. Although FIG. 5 is an example regarding the depth of the road infrastructure, the same applies to the height of the road infrastructure. The weight may be set to be greater the lower the road infrastructure. That is, the calculation unit 13 uses the inverse of the height of the road infrastructure as the weight. The depth or height of the road infrastructure may be acquired from the storage unit 10 where it is stored in advance, or may be acquired from road infrastructure information acquired by the acquisition unit 11 from the external device 3.

[0039] The calculation unit 13 may calculate the infrastructure impact degree further based on the number of years since the road infrastructure was laid. The calculation unit 13 may calculate the infrastructure impact degree score further based on the number of years since the road infrastructure was laid (relative to equation (2)) using the following equation (3). score=Y / 10*ΣΣ(w i / d i,j ) …(3)

[0040] In other words, the older the road infrastructure is, the greater the impact on the infrastructure. This is because the older the road infrastructure is, the more susceptible it is to deterioration and damage. Note that the division by "10" in equation (3) is for the purpose of aligning the other values.

[0041] The calculation unit 13 may calculate the infrastructure impact degree further based on the distance between the road infrastructure or the construction site and the construction workers or the waiting location of the construction workers. FIG. 6 is a diagram showing an example of the distance between the road infrastructure and the construction workers. In FIG. 6, a water pipe W, which is road infrastructure, and a construction worker P are included. The (shortest) distance between (the center line of) the water pipe W and the construction worker P is the distance d P The calculation unit 13 calculates the distance d P The infrastructure impact score score may be calculated further based on (for equation (2)). score=d P / 10*ΣΣ(w i / d i,j ) …(4)

[0042] In other words, the greater the distance between the road infrastructure and the construction workers, the greater the impact on the infrastructure. Note that the division by "10" in equation (4) is for the purpose of aligning the other values.

[0043] In the above description of FIG. 6, the road infrastructure may be replaced with a construction site, and the construction personnel P may be replaced with a waiting location for the construction personnel. For example, the calculation unit 13 calculates the infrastructure impact degree according to the distance, because the longer the distance between the nearby road infrastructure where construction is being carried out and the waiting location for the construction personnel, the longer it takes for emergency response personnel to arrive at the site. The construction site and the waiting location for the construction personnel may be acquired from the storage unit 10 where they are stored in advance, or may be acquired from construction information acquired by the acquisition unit 11 from the external device 3.

[0044] The calculation unit 13 may output the calculated infrastructure impact to the display unit 14, may store it in the storage unit 10, may display it to a user of the infrastructure impact calculation device 1 via the output device 1006 described below, or may output it to another device via a network, etc.

[0045] The display unit 14 performs display on a map based on the infrastructure impact degree calculated by the calculation unit 13. The display unit 14 may perform display on the map relating to construction objects and road infrastructure.

[0046] FIG. 7 is a diagram showing an example of a display based on the infrastructure impact level on a map. FIG. 7 is an example of a screen displayed by the display unit 14. The upper left of the example screen is a road image acquired from the vehicle 2. The road images may be displayed as a video arranged in chronological order. The right of the example screen is a map of the vicinity of the position indicated by the road image in the upper left of the example screen. The display unit 14 displays information related to road infrastructure superimposed on the map based on the road infrastructure information stored by the storage unit 10 or the road infrastructure information output by the acquisition unit 11. In FIG. 7, a dotted line indicating a water pipe W is displayed superimposed on the map.

[0047] The display unit 14 displays information about the construction object superimposed on a map based on the imaging position information output by the acquisition unit 11 or the imaging position information stored by the storage unit 10, and the extraction results stored by the storage unit 10 or the extraction results output by the extraction unit 12. In FIG. 7, a circle indicating the presence of a construction object O is displayed superimposed on the map. The display unit 14 may display information on the map based on at least one of the type of construction object, the number of detected construction objects, or the area of ​​the construction object. For example, the display unit 14 may change the color of the circle depending on the type of construction object, display the circle larger in proportion to the number of detected construction objects, display the circle larger in proportion to the area ratio of the construction objects, or display a heat map corresponding to the area ratio of the construction objects as a grid on the map.

[0048] The bottom left of Fig. 7 shows various types of information displayed by the display unit 14. The example screen shown in Fig. 7 displays the number of construction objects extracted by the extraction unit 12 (for the road image in the upper left of the example screen), the infrastructure impact degree output by the calculation unit 13, and information indicating whether the construction (near the position indicated by the road image in the upper left of the example screen) is notified construction. The information indicating whether the construction is notified construction is displayed by the display unit 14 based on construction information acquired by the acquisition unit 11 from the external device 3.

[0049] Next, an example of the process (method for calculating an impact on infrastructure) executed by the infrastructure impact calculation system 4 will be described with reference to Fig. 8. Fig. 8 is a sequence diagram showing an example of the process executed by the infrastructure impact calculation system 4.

[0050] First, the vehicle 2 captures a road image using the dashcam D (step S1). Next, the vehicle 2 transmits the road image and image capture position information to the infrastructure impact calculation device 1 (step S2). Next, the infrastructure impact calculation device 1 requests external information from the external device 3 (step S3). Next, the external device 3 transmits the external information in response to S3 (step S4). Next, the extraction unit 12 of the infrastructure impact calculation device 1 extracts a construction object based on the information received at S2 and S4 (step S5, extraction step). Next, the calculation unit 13 of the infrastructure impact calculation device 1 calculates an infrastructure impact based on the information received at S2 and S4 and the extraction result of S5 (step S6, calculation step). Next, the display unit 14 of the infrastructure impact calculation device 1 performs a display based on the infrastructure impact based on the information received at S2 and S4, the extraction result of S5, the calculation result of S6, etc. (step S7, display step).

[0051] The timing of S3 and S4 is not limited to after S2 and before S5, but may be any timing. For example, they may be executed whenever external information becomes necessary in the processing of the infrastructure impact calculation device 1.

[0052] Next, the effects of the infrastructure impact calculation device 1 according to the embodiment will be described.

[0053] According to the infrastructure impact calculation device 1, the calculation unit 13 calculates the infrastructure impact, which is the degree of impact of construction on road infrastructure, based on the distance between a construction object, which is one or more objects related to the construction, and road infrastructure, which is infrastructure laid below, above, or around the road. With this configuration, the infrastructure impact, which is the degree of impact of construction on road infrastructure, is calculated, making it possible to detect the impact of construction on infrastructure. In addition, it is possible to detect the degree of impact of construction on infrastructure.

[0054] Furthermore, according to the infrastructure impact calculation device 1, the calculation unit 13 may calculate the infrastructure impact further based on the type of each construction object. With this configuration, it is possible to calculate a more accurate infrastructure impact further according to the type of each construction object.

[0055] Furthermore, according to the infrastructure impact calculation device 1, the calculation unit 13 may calculate the infrastructure impact based on a distance that satisfies a predetermined criterion. With this configuration, for example, calculations for distances that do not satisfy the predetermined criterion can be omitted, thereby reducing the amount of calculations.

[0056] Furthermore, according to the infrastructure impact calculation device 1, the calculation unit 13 may calculate the infrastructure impact further based on the depth or height of the road infrastructure. With this configuration, it is possible to calculate a more accurate infrastructure impact further according to the depth or height of the road infrastructure.

[0057] Furthermore, according to the infrastructure impact calculation device 1, the calculation unit 13 may calculate the infrastructure impact further based on the age of the road infrastructure. With this configuration, it is possible to calculate a more accurate infrastructure impact that is further in accordance with the age of the road infrastructure.

[0058] Furthermore, according to the infrastructure impact calculation device 1, the calculation unit 13 may calculate the infrastructure impact based on the distance between the road infrastructure or the construction site and the construction personnel or the waiting location of the construction personnel. With this configuration, it is possible to calculate a more accurate infrastructure impact that is further adapted to, for example, the arrival time of the construction personnel at the site as a temporary response.

[0059] Furthermore, according to the infrastructure impact calculation device 1, the acquisition unit 11 may acquire road images captured on a road, the extraction unit 12 may extract construction objects included in the road images acquired by the acquisition unit 11, and the calculation unit 13 may calculate the infrastructure impact based on the distance between the construction objects extracted by the extraction unit 12 and the road infrastructure. With this configuration, the infrastructure impact can be more easily calculated based on the captured road images.

[0060] Furthermore, according to the infrastructure impact calculation device 1, the acquisition unit 11 may acquire road images captured by a dashcam D. This configuration makes it possible to use an existing dashcam D (and vehicle 2), thereby reducing the investment cost for building the infrastructure impact calculation system 4.

[0061] Furthermore, according to the infrastructure impact calculation device 1, the acquisition unit 11 may further acquire imaging position information relating to the position where the road image was captured, the extraction unit 12 may further extract relative position information relating to the relative position between the position where the road image was captured and the position of each construction object based on the imaging position information acquired by the acquisition unit 11, and the calculation unit 13 may calculate the distance between the construction object and the road infrastructure based on the imaging position information acquired by the acquisition unit 11, the relative position information extracted by the extraction unit 12, and information relating to the position of the road infrastructure that has been set in advance. With this configuration, it is possible to calculate a more accurate distance based on the position, thereby enabling a more accurate calculation of the infrastructure impact.

[0062] Furthermore, according to the infrastructure impact calculation device 1, the display unit 14 may perform display on a map based on the infrastructure impact calculated by the calculation unit 13. With this configuration, the user of the infrastructure impact calculation device 1 can easily check the display based on the infrastructure impact on the map.

[0063] The infrastructure impact calculation device 1 is also a system that recognizes objects from the video captured by the dashcam D and visualizes them on a map. More specifically, the infrastructure impact calculation device 1 is a system that recognizes target objects from the video captured by the dashcam D and, based on the location information of the dashcam D, expresses and visualizes the number and type of recognized objects on a map.

[0064] Previously, road construction work and other construction projects required advance notification to the companies that own the infrastructure or local governments to avoid damaging the buried infrastructure. However, some construction projects were not notified, and the companies that own the infrastructure or local governments had to patrol the area to identify the issues and issue instructions on-site. However, this required a lot of manpower.

[0065] The infrastructure impact calculation device 1 detects objects using images captured by a dashcam D, and visualizes the results on a map based on the location information of the dashcam D. By comparing this information with the installation status of various buried infrastructures and notified construction work, patrols become unnecessary.

[0066] The extraction unit 12 of the infrastructure impact calculation device 1 can be regarded as an object recognition engine, and the calculation unit 13 and display unit 14 of the infrastructure impact calculation device 1 can be regarded as a visualization system.

[0067] The infrastructure impact calculation device 1 may calculate a score according to the detection type (of the construction object), and calculate and visualize the urgency (infrastructure impact) in conjunction with the laying status of the buried infrastructure (road infrastructure).

[0068] The block diagrams used to explain the above embodiments show functional blocks. These functional blocks (components) are realized by any combination of at least one of hardware and software. Furthermore, the method for realizing each functional block is not particularly limited. That is, each functional block may be realized using a single device that is physically or logically coupled, or may be realized using two or more physically or logically separated devices that are directly or indirectly connected (for example, using wires, wirelessly, etc.) and these multiple devices.
