Description

Technical Field

[0001] The present invention relates to, for example, an information processing system, an information processing method, a program, and a program storage medium, and particularly to an information processing system, an information processing method, a program, and a program storage medium that apply and develop the basic configuration of mainly ETC (ELECTRONIC Toll Collection), which are applicable to the collection of usage fees at toll gates such as toll roads and parking lots.

Background Art

[0002] First, as this type of technology, in Patent Document 1, regarding the ETC part, while referring to several prior arts, it is shown that the NP reader 1C is a photographing means, and it discloses that "when a detection signal indicating the presence of vehicle A is output from the vehicle detector of the vehicle type discrimination device 1B, vehicle A is photographed, and an image including the license plate of the vehicle A (hereinafter, also referred to as an "NP image") is obtained."

[0003] Also, the user photographing unit 11 is also a photographing means (camera) (paragraph

[0032] ), and the monitoring camera 1F is a camera as the name implies (paragraph

[0028] ).

[0004] In other words, Patent Document 1 adopts the same technology as the previous technology for the ETC part, and in addition, it has a configuration of "ETC + camera" equipped with various cameras.

[0005] Here, Patent Document 2 is the patent gazette that is the registration result of Patent Document 1. Although there are various circumstances, as a result, it is patented after being limited to the content of claim 9 at the time of application, that is, the content with an additional analysis processing unit and fraud detection unit. Structurally, the part of the toll collection facility 1 at the site where there is a toll gate has a configuration in which inventive step is not recognized, and it is patented by adding analysis processing and fraud detection by the upper device 2.

[0006] In other words, it can be interpreted that, at the time of filing Patent Document 1, the basic components excluding the analysis processing unit and the fraud detection unit were largely known technology.

[0007] On the other hand, regarding the configuration of "ETC + camera," there are various prior art documents (especially patent documents), but to put it simply, the effective use of imaging means (cameras) has yielded acceptable results in the technology of detecting and preventing fraud and its applications. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Japanese Patent Publication No. 2019-148961 [Patent Document 2] Patent No. 7097193 [Overview of the Initiative] [Problems that the invention aims to solve]

[0009] Figure 8 is an explanatory diagram showing an image of the vicinity of a toll booth where the ETC system in its current state (conventional technology) is applied, Figure 9 is an explanatory diagram showing an image of a wide wireless communication area that does not take into account the narrowing of the area in the case of Figure 8, and Figure 10 is an explanatory diagram explaining the problems in the case of Figure 9.

[0010] The ETC system, as part of the overall system, includes a wireless communication function that allows toll booths and vehicles to send and receive ETC information by communicating wirelessly with specific vehicles that receive radio waves emitted from roadside wireless antennas.

[0011] The illustrated roadside wireless antenna E0 is responsible for any one toll booth within the overall wireless communication function. Although only the antenna portion for wireless communication is shown in the illustration, it has wireless control functions (not shown) that exchange various information with the central control unit that controls the entire ETC system. The roadside wireless antenna E0 communicates with specific vehicles located in the illustrated wireless communication area E0a.

[0012] Here, the wireless communication area E0a in Figure 8 is narrowly defined as the immediate vicinity of a specific vehicle. In contrast, the wireless communication area E0a in Figure 9 is a broad area that does not take narrowing into consideration.

[0013] In Figure 10, a following vehicle is present, resulting in two vehicles within the wireless communication area E0a shown in Figure 9. In this case, various problems may arise, such as applying the toll charges of the preceding vehicle to the following vehicle, or conversely, charging the preceding vehicle for the toll charges of the following vehicle, or even if it is determined that toll charges cannot be collected from either the preceding or following vehicle, both vehicles being allowed to pass, or a vehicle that should be stopped passing and another vehicle that should be stopped passing, etc.

[0014] Figure 10 illustrates the case where a following vehicle enters the wireless communication area E0a, but the cases are not limited to just the front-to-back relationship. For example, if the area is wide, vehicles in adjacent lanes may also enter the wireless communication area E0a, potentially causing various problems.

[0015] One solution to the problems that arise in these wide-area wireless communication regions E0a is the narrowed wireless communication region E0a shown in Figure 8, which is limited to a very narrow area (narrow range) that is just within the vicinity of a specific vehicle.

[0016] Furthermore, the direction of technological development pursued in each of the aforementioned prior arts also falls under the category of "narrowing the wireless communication domain."

[0017] There is a demand for shorter toll booth passage times using the ETC system, and because some vehicles attempt to pass through toll booths with extremely short following distances, including for the purpose of "fraud," there is a growing trend towards considering "narrowing the wireless communication area" at toll booths, which would further restrict the wireless communication area to a narrower range (region).

[0018] To achieve this "narrowing of the wireless communication range," antennas for wireless communication require high directivity, making it impossible to use general-purpose, inexpensive antennas. Furthermore, these factors necessitate further technological advancements, as well as the elimination of the high costs associated with adopting new technologies.

[0019] Furthermore, when installing wireless antennas in existing parking lots or similar locations, rather than in toll booths specifically designed for ETC on expressways, radio waves may reflect off the ceilings and walls of the facilities, making unexpected communication with other vehicles more likely. This suggests that simply "narrowing the wireless communication area" may not solve the problem.

[0020] Therefore, the present invention aims to solve the problems of the prior art described above, and aims to provide an information processing system, information processing method, program, and program storage medium that can eliminate false detection by combining existing technologies without requiring antenna directivity for narrowing the wireless communication range. [Means for solving the problem]

[0021] Therefore, in order to solve the above-mentioned problems, the information processing system according to the first aspect of the present invention includes: a wireless detection function that can collect wireless detection information that can be detected via wireless communication from among the vehicle information of a vehicle to be detected by communicating with one or more vehicles in a detectable wireless communication area; a separate detection function that can detect one or more vehicle information included in the wireless detection information as separate detection information for a vehicle in a vehicle identification area for identifying one of the one or more vehicles, in a method other than that of the wireless detection function; and a vehicle identification function that, when the separate detection information matches the vehicle information detected by the wireless detection function, can identify the vehicle having the matching vehicle information as a specific vehicle.

[0022] Also, as a fourteenth aspect corresponding to the first aspect, an information processing method includes: a wireless detection step of communicating and collecting, with one or more vehicles existing in a detectable wireless communication area, wireless detection information that can be detected via wireless communication among the vehicle information of a vehicle to be detected; a separate detection step of detecting, for a vehicle existing in a vehicle identification area for identifying one of the one or more vehicles, one or more pieces of vehicle information included in the wireless detection information as separate detection information by a method different from the wireless detection function; and a vehicle identification step of being able to identify, as a specific vehicle, a vehicle having the matching vehicle information when the separate detection information matches the vehicle information detected in the wireless detection step.

[0023] Also, as a fifteenth aspect corresponding to the first aspect, a program causes the above-described information processing system to execute the above-described information processing method. That is, the program causes a computer to execute: a wireless detection function of communicating and collecting, with one or more vehicles existing in a detectable wireless communication area, wireless detection information that can be detected via wireless communication among the vehicle information of a vehicle to be detected; a separate detection function of detecting, for a vehicle existing in a vehicle identification area for identifying one of the one or more vehicles, one or more pieces of vehicle information included in the wireless detection information as separate detection information by a method different from the wireless detection function; and a vehicle identification function of being able to identify, as a specific vehicle, a vehicle having the matching vehicle information when the separate detection information matches the vehicle information detected by the wireless detection function.

[0024] Also, as a sixteenth aspect corresponding to the first aspect, a program storage medium stores the above-described program so that it can be used by the above-described information processing system.

[0025] According to these information processing systems or information processing methods, or according to the programs or program storage media of these aspects, by means of a wireless detection function, among the vehicle information of the vehicle to be detected, the wireless detection information that can be detected via wireless communication can be communicated and collected with one or more vehicles existing in the detectable wireless communication area, and by means of a separate detection function, for vehicles existing in a vehicle identification area for identifying one of the one or more vehicles, one or more vehicle information included in the wireless detection information can be detected as separate detection information by a method different from the wireless detection function, and by means of a vehicle identification function, when the separate detection information matches the vehicle information detected by the wireless detection function, the vehicle having the matched vehicle information can be identified as the specific vehicle.

[0026] In this case, first, by means of the wireless detection function, it is possible to collect the wireless detection information of one or more vehicles existing in the wireless communication area. Here, "one or more vehicles" is meant to include "a plurality of vehicles", and "a plurality of vehicles" is tolerated.

[0027] In the concept in the prior art described above, as previously mentioned in FIG. 10, various problems occur, so wireless communication with "a plurality of vehicles" cannot be tolerated, and the aim is "to narrow the wireless communication area". In contrast, in this case, in order to tolerate "a plurality of vehicles", it is not necessary to "narrow the wireless communication area". Rather, considering collecting the wireless detection information of as many vehicles as possible almost simultaneously, it may be recommended to "widen the wireless communication area".

[0028] However, at the time when the wireless detection information is collected, the wireless detection information is obtained including the specific vehicle to be identified and vehicles other than the specific vehicle.

[0029] On the other hand, by means of a separate detection function, for vehicles existing in a vehicle identification area, one or more vehicle information included in the wireless detection information can be detected as separate detection information by a method different from the wireless detection function, whereby the information for identifying the specific vehicle is made complete.

[0030] Furthermore, the vehicle identification function allows the vehicle with matching vehicle information to be identified as a specific vehicle when separate detection information matches vehicle information detected by the wireless detection function, thereby completing the objective of this project, which is "identification of specific vehicles."

[0031] Therefore, in this case (this embodiment), false detection can be eliminated by combining existing technologies without requiring antenna directivity for narrowing the wireless communication range. Consequently, the high costs associated with adopting advanced technologies for "narrowing the wireless communication range" are avoided.

[0032] Furthermore, the aforementioned "wireless detection function" comprises a "wireless communication function for wireless communication" and a subsequent "detection (information gathering) function" that collects (acquires) "wireless detection information that can be detected via wireless communication from among the vehicle information." Since the purpose is strictly to "acquire at least wireless detection information," here and in subsequent explanations, we will not use the term "wireless control function," which is a concept that includes other functions, but will simply use the term "wireless detection function."

[0033] Furthermore, a typical example of a manner in which the aforementioned "wireless communication function" is realized is the aforementioned "roadside wireless antenna," which is "part of the wireless communication function." This is particularly evident in ETC systems on toll roads. However, from a technical standpoint, neither "roadside" nor "antenna" is essential as a component of the system requirements. Depending on the definition of "roadside," for example, in parking lots and other uses, "roadside" is not essential as "part of the wireless communication function."

[0034] Furthermore, while the definition of "antenna" varies, if, for example, near-field communication (NFC) is used, the area is limited without requiring "narrowing of the wireless communication area," making it usable with combinations of current technologies. This can be particularly useful in places where electric vehicles have contactless charging capabilities on the road. In short, any "wireless detection function that can acquire at least wireless detection information via wireless communication" is acceptable, regardless of the type of wireless communication.

[0035] Furthermore, while the "roadside wireless antenna E0" shown in Figures 8-10 above was responsible for any one toll booth within the overall "wireless communication function," to distinguish it from this, the one responsible for any one toll booth within the overall "wireless detection function," which will be described later, has functions that include part of the "detection (information collection) function" after communication, and therefore will be referred to as a "wireless sensor S0," etc.

[0036] Furthermore, as an information processing system relating to a second embodiment, in the first embodiment, the wireless detection information may include the same vehicle information as the imaging detection information that can be detected by imaging, and the separate detection function may be equipped with an imaging detection function that can detect the imaging detection information as the separate detection information.

[0037] In this case, the wireless detection information includes the same vehicle information as the image detection information that can be detected by imaging, and the separate detection function is equipped with an image detection function that can detect the image detection information as separate detection information. Therefore, the image detection function can detect the image detection information as separate detection information, and when it matches the detected vehicle information in the wireless detection information (the same vehicle information as the image detection information), the vehicle with the matching vehicle information can be identified as a specific vehicle.

[0038] In the case of imaging, the number of vehicles being imaged is not an issue. Therefore, it is basically limited to one vehicle, but it may be possible to detect imaging information for multiple vehicles simultaneously. In that case, it may be possible to identify multiple specific vehicles that have passed through the wireless communication area at once.

[0039] Furthermore, as an information processing system relating to a third embodiment, in the second embodiment, the image detection information may include vehicle number information.

[0040] By regulation, the wireless detection information in the ETC system includes the vehicle's license plate number. Therefore, it is possible to identify vehicles that match the vehicle and license plate number indicated by the image detection information in the image capture results from the detected wireless detection information. This allows it to be recognized that the identified vehicle passed through the wireless communication area where the wireless detection information was acquired.

[0041] Furthermore, as an information processing system relating to the fourth embodiment, in the first embodiment, the wireless communication area may include the area of ​​a toll booth on a toll road.

[0042] In this case, the wireless communication area includes the area of ​​toll booths on toll roads, making it easier to obtain wireless detection information of vehicles present at the toll booths.

[0043] Furthermore, as an information processing system relating to the fifth embodiment, in the first embodiment, the vehicle identification area may include lanes on a toll road.

[0044] In this case, the vehicle identification area includes lanes on toll roads, making it easier to identify vehicles located in the lanes of toll roads as specific vehicles.

[0045] Furthermore, as an information processing system relating to the sixth embodiment, in the first embodiment, the separate detection function may be configured to detect separate detection information of multiple vehicles lined up within any single lane width direction.

[0046] In this case, the separate detection function can detect separate detection information for multiple vehicles lined up within any given lane width. When multiple vehicles are lined up within any given lane width, for example, when two or more passenger cars are driving side by side within the same lane width, with one car attempting to overtake the other, and one car crossing the lane boundary line, or when two passenger cars are driving side by side, each crossing the opposite boundary line of the other, etc., in this case, even if two or more vehicles are driving within the same lane width, the separate detection information for multiple lined up vehicles can be detected, and therefore, separate detection information for each vehicle can be obtained.

[0047] Furthermore, as an information processing system relating to the seventh aspect, in the first aspect, the separate detection function may be configured to detect separate vehicle detection information from both the front and rear of the direction of travel for any one lane.

[0048] In this case, the separate detection function can detect separate detection information for vehicles from both the front and rear in the direction of travel for any given lane, making it easier to acquire separate detection information for each vehicle. For example, when using image detection information as separate detection information, even in situations where sufficient image detection information cannot be acquired with one image due to overlapping images of vehicles traveling in front, behind, or adjacent / parallel, or due to poor image quality or image loss caused by dirt or distortion on the vehicle, this system can detect image detection information for vehicles from both the front and rear in the direction of travel for any given lane, making it easier to acquire image detection information for each vehicle. In particular, when the vehicle is a motorcycle, the license plate showing the vehicle number information is only on the rear, so rear image detection is essential.

[0049] Furthermore, as an information processing system relating to the eighth aspect, in the first aspect, if there is a single charge within the area subject to usage fees, the wireless communication area and the vehicle-specific area may include a predetermined transit area through which all vehicles pass at least once.

[0050] In this case, if the area subject to usage fees (e.g., a toll road) has a single fee, the wireless communication area and the vehicle identification area include a predetermined passage area that all vehicles pass through at least once. Therefore, by reliably acquiring wireless detection information and other detection information (e.g., image detection information) when each vehicle passes through that predetermined passage area, the identification of a specific vehicle can be reliably performed.

[0051] Furthermore, as an information processing system relating to the ninth aspect, in the first aspect, if the charges for the area subject to usage fees are section-based charges from any entrance to any exit, the wireless communication area may include an area for detecting wireless detection information of all vehicles passing through any one entrance, and the vehicle identification area may include an area for detecting separate detection information of all vehicles passing through any one exit.

[0052] In this case, if the toll for the area subject to usage fees (e.g., a toll road) is a section-based fee from any entrance to any exit, the wireless communication area includes an area for detecting wireless detection information for all vehicles passing through any single entrance, so wireless detection information can be reliably obtained when each vehicle passes through. The vehicle identification area includes an area for detecting separate detection information for all vehicles passing through any single exit, so separate detection information (e.g., image detection information) can be reliably obtained when each vehicle passes through, thereby reliably identifying a specific vehicle.

[0053] Furthermore, as an information processing system relating to the tenth embodiment, in the first embodiment, if the fee for the area subject to usage fees is a section-based fee from any entrance to any exit, the system may include an area for detecting separate detection information for all vehicles passing through any single entrance, and the vehicle identification area may include an area for detecting wireless detection information for all vehicles passing through any single exit.

[0054] In this case, if the toll for the area subject to usage fees (e.g., a toll road) is a section-based fee from any entrance to any exit, the system includes an area for detecting separate detection information for all vehicles passing through any single entrance, so that separate detection information (e.g., image detection information) can be reliably obtained when each vehicle passes through. Furthermore, the vehicle identification area includes an area for detecting wireless detection information for all vehicles passing through any single exit, so that the identification of a specific vehicle can be reliably performed.

[0055] Furthermore, as an information processing system relating to the eleventh embodiment, in the first embodiment, the wireless communication area may include the area of ​​the parking lot entrance, and the vehicle identification area may include an area for detecting separate detection information for all vehicles passing through the parking lot exit.

[0056] In this case, the wireless communication area includes the area of ​​the parking lot entrance and includes an area for detecting wireless detection information of all vehicles passing through the parking lot entrance, so wireless detection information can be reliably acquired when each vehicle passes through. The vehicle identification area includes an area for detecting separate detection information of all vehicles passing through the parking lot exit, so by reliably acquiring separate detection information (e.g., image detection information) when each vehicle passes through, the identification of a specific vehicle can be reliably performed.

[0057] Furthermore, as an information processing system relating to the twelfth embodiment, in the first embodiment, the system may detect separate detection information for all vehicles passing through the parking lot entrance, and the vehicle identification area may include an area for detecting wireless detection information for all vehicles passing through the parking lot exit.

[0058] In this case, separate detection information (e.g., image detection information) for all vehicles passing through the parking lot entrance can be reliably acquired, and the vehicle identification area includes an area for detecting wireless detection information for all vehicles passing through the parking lot exit, so that the identification of a specific vehicle can be reliably performed as each vehicle passes through.

[0059] Furthermore, as an information processing system relating to the 13th embodiment, in the first embodiment, the wireless communication area may include multiple locations divided into multiple areas, and the wireless detection information acquired corresponding to each of the multiple locations may be shared as wireless detection information corresponding to all of the multiple locations.

[0060] In this case, the wireless communication domain includes multiple locations divided into multiple domains, and the wireless detection information acquired for each of these locations is shared as wireless detection information corresponding to all locations in the multi-location domain. Therefore, there is no loss or duplication of wireless detection information, and it can be managed comprehensively and collectively. [Effects of the Invention]

[0061] According to each aspect of the present invention, it is possible to eliminate false detection by combining existing technologies without requiring antenna directivity for narrowing the wireless communication range. [Brief explanation of the drawing]

[Figure 10] Figure 9 is an explanatory diagram illustrating the scenario when a following vehicle is following behind. [Modes for carrying out the invention]

[0063] The concept of the present invention is described more fully below with reference to the accompanying drawings illustrating specific embodiments of the concept of the present invention. However, the concept of the present invention can be embodied in many different forms and should not be construed as being limited to the embodiments described herein. Rather, these embodiments are provided as examples so that this disclosure is thorough and complete and fully conveys the scope of the concept of the present invention to those skilled in the art. Similar numbers refer to similar elements throughout the description.

[0064] The following sections will be explained in order: [1. Example of the basic system function configuration], [2. Example of the practical application function configuration], [3. Specific examples of applicable facilities], and [4. Summary].

[0065] [1. Example of a system's basic function configuration] Figure 1 is an explanatory diagram of the functional blocks of the basic functional configuration of the "information processing function" in the embodiment.

[0066] Furthermore, among the vehicle information of the vehicle to be detected, vehicle information that can be detected via wireless communication is referred to as wireless detection information, and the area in which wireless detection information can be detected is referred to as the wireless communication area. Among the vehicle information, vehicle information that is identical to one or more vehicle information included in the wireless detection information but can be detected by a method other than the wireless detection function is referred to as separate detection information. As an example of separate detection information, vehicle information that can be detected by imaging is referred to as imaging detection information, and the area in which imaging detection information can be detected is referred to as the imaging detection area. The area used to identify the final target vehicle for detection is referred to as the vehicle identification area. Wireless detection information and separate detection information include the time at which detection occurred.

[0067] Furthermore, the words in brackets [] indicate the corresponding terms within the claims, but if they match the expressions in the detailed explanation below, the brackets [] will be omitted. Also, the brackets [] will be included only when necessary, and their frequent appearance will be avoided as much as possible.

[0068] As shown in Figure 1, the information processing function (system / device / part / method / process, etc.) 1Aa comprises an information control function (system / device / part / method / process, etc.) 10, a wireless detection function (system / device / part / method / process, etc.) S, and an imaging detection function (system / device / part / method / process, etc.) V.

[0069] Here, an information processing function (system / device / part / method / process, etc.) 1Aa functionally possesses an "information processing function," but from a hardware perspective, the function is executed by a part of the hardware configuration, and can therefore be called an "information processing system," "information processing device," or "information processing unit." On the other hand, from an algorithmic perspective, the function is executed by a part of the overall algorithm, and can therefore be called an "information processing method" or "information processing process."

[0070] Therefore, if we were to express these collectively, it might be appropriate to express (describe) them as "Information Processing Function (System / Device / Part / Method / Process, etc.) 1Aa" as described above. However, in the following explanation, we will simplify and limit ourselves to expressing only the function, that is, only "Information Processing Function 1Aa". Similarly, other functions (systems / devices / parts / methods / processes, etc.) will also be limited to expressing only the function.

[0071] Therefore, as shown again in Figure 1, the information processing function 1Aa comprises an information control function 10, a wireless detection function S, and an imaging detection function [separate detection function] V.

[0072] Within the central control function C, which is commonly referred to as a server, the information control function 10 is composed of what is commonly referred to as a "CPU," and is responsible for controlling the entire information processing within the central control function C, or, if necessary, the entire information processing within the information processing function [information processing system] 1Aa.

[0073] In this embodiment, the vehicles designated as "specific vehicles" are, for example, vehicles subject to toll collection on toll roads, etc. In order to collect tolls, it is necessary to identify the vehicles subject to toll collection and to perform a predetermined collection process for toll collection based on the wireless detection information of the identified vehicles (specific vehicles).

[0074] Therefore, the wireless detection function S has one or more wireless sensors S0~(S0, S1, ...) and detects wireless detection information of one or more vehicles. Here, it detects wireless detection information of vehicles that can be detected in the wireless communication area, regardless of whether they are specific vehicles subject to toll collection.

[0075] Here, one or more wireless sensors S0~(S0, S1, ...) are, for example, installed at each toll booth on a toll road, and have a wide-area antenna capable of communicating simultaneously or sequentially with one or more vehicles present in the wireless communication area (toll booth, etc.). These sensors detect wireless detection information of one or more vehicles via the wide-area antenna and store the detected wireless detection information as element information of a list stored in the wireless detection information storage function 1111 described later.

[0076] The wireless detection function S, which has these features, collects the wireless detection information as element information of the list detected by one or more wireless sensors S0~(S0, S1, ...) and reports (transmits information) to the information control function 10, either in a condensed manner or simultaneously from each wireless sensor S0, etc.

[0077] Next, the imaging detection function [separate detection function] V has one or more imaging sensors V0~(V0, V1, ...) and captures imaging detection information.

[0078] In this case, the imaging detection area is an area capable of capturing images of vehicles that are stopped in or passing through an area where tolls can be collected. Therefore, one or more imaging sensors V0~(V0, V1, ...) are installed, for example, in the case of a toll road, in areas capable of capturing images of vehicles that are stopped in or passing through each toll booth, i.e., near the toll booths. By having one or more imaging sensors V0~(V0, V1, ...), the imaging detection function V becomes capable of detecting imaging information of vehicles present in the imaging detection area.

[0079] The imaging detection function V collects imaging detection information detected by one or more imaging sensors V0~(V0, V1, ...) and reports (transmits) it to the information control function 10 either in a consolidated manner or simultaneously from each imaging sensor V0, etc.

[0080] As mentioned above, the information control function 10 is composed of what is commonly referred to as a "CPU," and is responsible for the overall control of information processing within the central control function C and, if necessary, within the information processing function 1Aa.

[0081] The information control function 10 includes a vehicle identification function 110 and a fare collection function 120, as shown in the figure.

[0082] The vehicle identification function 110 includes a wireless detection information processing function 111 and an image detection information processing function 112, and the wireless detection information processing function 111 includes a wireless detection information storage function 1111. The image detection information processing function 112 may also include an image detection information storage function, etc.

[0083] The wireless detection information processing function 111 stores the wireless detection information detected and reported (received) as list information in the wireless detection information storage function 1111 by the wireless detection function S.

[0084] Similarly, the image detection information processing function 112 receives (receives) image detection information from the image detection function V. In this case, however, it immediately identifies one of the one or more vehicles listed in the wireless detection information of the wireless detection information storage function 1111 that matches the vehicle for which the image detection information was detected, as the specific vehicle.

[0085] In other words, the vehicle identification function 110 includes a wireless detection information processing function 111 and an image detection information processing function 112, and these functions in cooperation with each other to enable the identification of a specific vehicle.

[0086] The following fare collection function 120 has the capability to perform a predetermined fare collection process for collecting usage fees from the specific vehicle identified above, and performs the fare collection process.

[0087] As described above, the information processing function 1Aa has one or more wireless sensors S0~(S0, S1, ...) for the wireless detection function S, each of which has a wide-area antenna capable of communicating simultaneously or sequentially with multiple vehicles present in a wireless communication area (toll booth, etc.), and can detect wireless detection information of one or more vehicles via the wide-area antenna.

[0088] Figure 2 is an explanatory diagram showing an image of the area near a toll booth to which the information processing function of this embodiment is applied.

[0089] As shown in Figure 2, any one wireless sensor belonging to the wireless detection function S (wireless sensor S0 is shown here as an example) has a wireless detection function, which is not shown in the figure, that exchanges various information with the central control function C, although only the antenna portion for wireless communication is shown in the figure. Wireless sensor S0 communicates with a specific vehicle located in the wireless sensor detection area S0a shown in the figure and detects the wireless detection information of that specific vehicle.

[0090] Figure 3 is an explanatory diagram showing an image of a wide-area wireless communication domain without considering the narrowing of the area in the case of Figure 2, and Figure 4 is an explanatory diagram showing an image of the case where a following vehicle is following in Figure 3.

[0091] In the case of the wide-area wireless communication region S0a shown in Figure 3, similar to the case in Figure 2, the wireless sensor S0 communicates with vehicles located in the illustrated wireless communication region S0a and detects wireless detection information from each vehicle.

[0092] As shown in Figure 4, the presence of two (or more) vehicles within the same wireless communication area E0a can cause various problems, as mentioned above. However, this case is completely different.

[0093] In other words, the wireless detection function S of this embodiment has one or more wireless sensors S0~(S0, S1, ...), each having a wide-area antenna capable of communicating simultaneously or sequentially with multiple vehicles present in a wireless communication area (toll booth, etc.), and is capable of detecting wireless detection information of one or more vehicles via the wide-area antenna.

[0094] To illustrate with reference to the diagram, any one toll booth can be described as follows: Any one wireless sensor belonging to the wireless detection function S (wireless sensor S0 is used as an example here) can communicate with one or more vehicles located within the wireless sensor detection area S0a shown in the diagram and collect wireless detection information. Here, "one or more vehicles" includes "multiple vehicles," thus acknowledging the presence of "multiple vehicles."

[0095] In the conventional approach described above, as shown in Figure 10, various problems arise, making wireless communication with "multiple vehicles" unacceptable, and thus aiming for "narrowing of the wireless communication area." In contrast, in this case, since "multiple vehicles" are permitted, "narrowing of the wireless communication area" is not necessary. Rather, considering the need to collect wireless detection information from as many vehicles as possible almost simultaneously, "widening of the wireless communication area" may be recommended.

[0096] However, when collecting wireless detection information, the system acquires wireless detection information that includes not only the specific vehicle to be identified, but also other vehicles.

[0097] On the other hand, the imaging detection function [separate detection function] V can detect one or more vehicle information items (specifically, license plate information) included in the wireless detection information for vehicles located in the imaging detection area [vehicle identification area] Va, and this provides the information necessary to identify a specific vehicle.

[0098] To illustrate this with an arbitrary toll booth, the image sensor V0 can detect vehicle numbers that are the same as those included in the wireless detection information for vehicles within the image sensor detection area V0a, thereby providing the necessary information to identify a specific vehicle.

[0099] Then, as explained in Figure 1, the vehicle identification function 110, when the image detection information [separate detection information] matches the vehicle information detected by the wireless detection function V, makes it possible to identify the vehicle with the matching vehicle information as a specific vehicle, thereby completing the objective of this case, "identification of a specific vehicle".

[0100] In addition, while Figure 4 above shows the case where a following vehicle enters the wireless communication area S0a, vehicle information may be actively collected not only in relation to the preceding vehicle, but also, for example, from vehicles in adjacent lanes.

[0101] Therefore, in this embodiment, false detection can be eliminated by combining existing technologies without requiring antenna directivity for narrowing the wireless communication range. Consequently, the high costs associated with adopting advanced technologies for "narrowing the wireless communication range" are avoided.

[0102] Therefore, unlike conventional technologies, it is not necessary to "narrow the wireless communication range." On the contrary, in order to enable the use of general-purpose, low-directional, and inexpensive wide-area antennas, it is better to aim for "wider wireless communication range," which is based on the exact opposite idea.

[0103] In cases where multiple vehicles are lined up within any single lane width, for example, when two or more passenger cars are driving side-by-side within a single lane width, with one car attempting to overtake the other, and one car crossing the lane boundary line, or when two passenger cars are driving side-by-side, each crossing the opposite boundary line of the other, etc., in this case, even if two or more vehicles are driving within a single lane width, it is possible to detect separate detection information for each of the multiple vehicles driving side-by-side, and therefore separate detection information for each vehicle can be obtained.

[0104] Furthermore, for any given lane, it may be possible to detect separate vehicle detection information from both the front and rear in the direction of travel.

[0105] In this case, the separate detection function can detect separate vehicle detection information from both the front and rear of any single lane in the direction of travel, making it easier to acquire separate detection information for each vehicle.

[0106] For example, when using image-captured detection information as separate detection information, even in situations where sufficient image-captured detection information cannot be obtained with one image capture due to overlapping images of vehicles traveling in front, behind, or adjacent to / parallel to, or due to poor image quality or image loss caused by dirt or distortion on the vehicles, in this case, it is possible to detect image-captured detection information of vehicles from both the front and rear in the direction of travel for any given lane, making it easier to obtain image-captured detection information for each vehicle.

[0107] Especially in the case of motorcycles, since the license plate showing the vehicle number is only located at the rear, rear-facing image detection is essential.

[0108] Note that Figure 1 is an explanation of the basic functional configuration, and therefore omits details such as the network infrastructure, although these may be essential in practice.

[0109] Of course, in cases where the information processing function 1Aa is used, for example, within the same premises such as a parking lot, and the wireless detection function S and imaging detection function V are not in a remote location but are geographically close to the information control function 10, a wired connection is also possible, and a network is not necessarily required. Furthermore, even in the case of wireless connections in remote locations, if a large company has a dedicated wireless line, a network is not necessary, and a direct one-to-one connection is sufficient.

[0110] On the other hand, even if the wireless detection function S or the imaging detection function V are located far from the information control function 10, transmission and reception can be processed without hindrance by using a predetermined network function.

[0111] Figure 5 is an explanatory diagram similar to Figure 1, showing the case where the roadside detection information network function Nr is added to the "information processing function" in Figure 1.

[0112] As shown in Figure 5, the information processing function 1Ab, like the information processing function 1Aa described above in Figure 1, includes an information control function 10, a wireless detection function S, and an imaging detection function V, and further includes a roadside detection information network function Nr.

[0113] First, the roadside detection information network function Nr includes the wireless detection information network function Ns and the image detection information network function Nv, and through these, information is exchanged between the wireless detection function S and the information control function 10, and between the image detection function V and the information control function 10. As a result, even if the wireless detection function S or the image detection function V is located far from the information control function 10, transmission and reception can be processed without any problems.

[0114] In this case, the wireless detection function S in Figure 1 collects the wireless detection information as element information of the list detected by the one or more wireless sensors S0~(S0, S1, ...) and reports (transmits information) to the information control function 10, or more specifically to the wireless detection information processing function 111 of the vehicle identification function 110, via the wireless detection information network function Ns, either simultaneously or in parallel from each wireless sensor S0, etc.

[0115] In this case, since the exchange of information between the wireless detection function S and the vehicle identification function 110 is performed via a predetermined wireless detection information network function Ns, processing can be carried out without any problems even if the installation locations of the wireless detection function S and the vehicle identification function 110 are far apart from each other.

[0116] Furthermore, in Figure 1, the aforementioned imaging detection function V collects imaging detection information detected by one or more imaging sensors V0~(V0, V1, ...) and reports (transmits information) to the information control function 10, or more specifically to the imaging detection information processing function 112 of the vehicle identification function 110, via the imaging detection information network function Nv, either in a consolidated manner or simultaneously from each imaging sensor V0, etc.

[0117] In this case, since the exchange of information between the image detection function V and the vehicle identification function 110 is performed via a predetermined image detection information network function Nv, processing can be performed without problems even if the installation locations of the image detection function V and the vehicle identification function 110 are far apart from each other.

[0118] Here, I will give some more detailed and practical examples.

[0119] First, the wireless detection function S may be equipped with a wide-area antenna function that enables the exchange of wireless detection information with vehicles within the entire wireless communication area set up on the toll road. This is precisely based on the idea of ​​"expanding the wireless communication area" and does not require "narrowing the wireless communication area," so it is possible to use a general-purpose, low-directivity, and inexpensive wide-area antenna.

[0120] Furthermore, the imaging detection function V may include a camera function capable of capturing images of vehicles within the entire imaging detection area set within the toll road.

[0121] By adopting a wide-area antenna function, there is no need to wait for technological advancements to narrow the wireless communication range, nor will it result in high costs due to the adoption of advanced technology. By adopting a camera function, the problem of false detection can be resolved by combining imaging detection with widening the wireless communication range.

[0122] Furthermore, the wide-area antenna function may be equipped with a roadside antenna for communicating with vehicles on toll roads, and the camera function may be equipped with a roadside camera for imaging vehicles on toll roads. By utilizing these roadside antennas and roadside cameras, it becomes possible to acquire wireless detection information and image detection information for identifying vehicles on toll roads.

[0123] In this case, both the roadside antenna and roadside camera can be general-purpose and inexpensive, so there is no need to wait for "technological advancements" to "narrow the wireless communication range," nor will it result in high costs due to the adoption of advanced technology. Furthermore, by combining image detection with "widening the wireless communication range," the problem of false detection can also be resolved.

[0124] Therefore, according to the information processing function of this embodiment, when applied as a toll collection system for toll roads, it is possible to eliminate false detections by combining existing technologies without requiring antenna directivity for narrowing the wireless communication range.

[0125] Furthermore, in this specific example, by employing the roadside detection information network function Nr, information processing of communications regarding wireless detection information and image detection information is performed, enabling information processing without problems even if the wireless detection function, image detection function and server are located in remote locations. In this specific example, at least a part of at least one of the functions of the wireless detection function S, image detection function V, and roadside detection information network function Nr may be installed on a gantry that spans the width of the toll road.

[0126] In this case, some of the detection functions, such as the wireless detection function S, the imaging detection function V, and the roadside detection information network function Nr, are installed on the gantry above the toll road and are located near the vehicle to be detected. This can be expected to have positive effects on the detection environment and detection status, such as improved sensitivity and response speed.

[0127] [2. Example Configuration of Practical Application Functions of the System] Figure 6 is an explanatory diagram of the functional blocks of the practical (applied) functional configuration when the "information processing function" of the embodiment is implemented in an existing general-purpose system. Note that explanations that overlap with the above explanations in the information processing function 1Aa in Figure 1 and information processing function 1Ab in Figure 2 are omitted as appropriate.

[0128] As shown in Figure 6, the information processing function 1B includes a central control function C, a network function N, a wireless detection function S, and an imaging detection function [separate detection function] V.

[0129] As with the explanations in Figures 1 and 5, the relevant (corresponding) terms within the claims are indicated within the brackets []. However, if the expression matches the one used in the detailed explanation below, the brackets [] will be omitted. Furthermore, the brackets [] will be included only when necessary, and their frequent appearance will be avoided as much as possible. With the above summarized, the explanation continues below.

[0130] Furthermore, regarding the hardware aspects, for example, the central control function C shown in Figure 6 is composed of what is commonly referred to as a "computer," and some or all of this may be configured using so-called cloud computing via any or specific network.

[0131] Furthermore, regarding the algorithmic aspects, so-called information processing includes both "A-type," where an algorithm is implemented on the information processing function (so-called computer, etc.) side in the information processing process and the information as a result of the processing is obtained by performing the processing itself, and "B-type," where the information as a result of the processing is obtained from an external source. In "B-type," the processing result to be obtained may be one in which the results of information processing are automatically input by another external system, or it may be one in which a human makes corrections to the results of automatic processing based on their own judgment, or a human input is accepted.

[0132] The central control function C will be discussed later, but first, here, information is exchanged between the wireless detection function S and the central control function C, and between the imaging detection function V and the central control function C, via the network function N. As a result, even if the wireless detection function S and the imaging detection function V are located far from the central control function C, transmission and reception can be processed without any problems.

[0133] Furthermore, as shown in the figure, this network function N includes comprehensive network functions, including the wireless detection information network function Ns and the image detection information network function Nv described in Figure 5. It may also include the roadside detection information network function Nr described in Figure 5, and similarly, a gantry may be used.

[0134] Furthermore, similar to the examples in Figures 1 and 5, if the information processing function 1B is used within the same premises, such as a parking lot, and the wireless detection function S and imaging detection function V are not located far from the central control function C, a wired connection is also possible, and the network function N is not necessarily required. Also, even in the case of wireless connections at remote locations, if a large company has a dedicated wireless line, a network is not necessary, and a direct one-to-one connection is sufficient.

[0135] Here, as in the examples in Figures 1 and 5, the vehicle information detected via wireless communication is wireless detection information, the area in which it can be detected is the wireless communication area, and vehicles from which wireless detection information is detected are subject to the collection of usage fees. Therefore, in order to collect usage fees, it is necessary to identify the vehicles subject to collection and to perform a predetermined collection process for usage fees based on the wireless detection information of those identified vehicles (specific vehicles).

[0136] However, detailed explanations of the wireless detection function S and the imaging detection function V are omitted as they overlap with the explanations in Figures 1 and 5.

[0137] In other words, the wireless detection function S collects wireless detection information as element information of a list detected by one or more wireless sensors S0~(S0, S1, ...) and reports (transmits information) it to the central control function C, or more specifically to the information control function 10, via the network function N, or directly, either simultaneously or in parallel from each wireless sensor S0, etc.

[0138] Similarly, the imaging detection function V collects imaging detection information detected by one or more imaging sensors V0~(V0, V1, ...) and reports (transmits information) it to the central control function C, or more specifically to the information control function 10, via the network function N or directly, either simultaneously or in parallel from each imaging sensor V0, etc.

[0139] As shown in Figure 6, the central control function C includes an information control function 10, an information notification function 20, an information acquisition function 30, an information storage function 40, and an information communication function 50.

[0140] Within the central control function C, the information control function 10 is composed of what is commonly referred to as a "CPU," and is responsible for controlling the entire information processing within the central control function C, or, if necessary, the entire information processing within the information processing function [information processing system] 1B.

[0141] Furthermore, the information notification function 20 may consist of a display or LED screen as the notification means, or it may also consist of a speaker, vibrator, or other means that notify by sound or vibration, or a combination thereof. In addition, the information acquisition function 30 may consist of a keyboard or mouse, or a so-called sensor system such as a barcode reader or scanner, or a combination thereof. Alternatively, it may be configured using a tablet that serves both information notification and information acquisition. In addition, the information storage function 40 can be configured using various types of memory or servers, and the information communication function 50 can be configured using various communication means.

[0142] Furthermore, by actively utilizing the comprehensive functions including the algorithmic and hardware aspects mentioned above, and especially by actively using a cloud-based system to facilitate information collection and storage, it is possible to create a self-developing configuration. In other words, in this case, it would be possible to adopt a configuration that employs AI that develops and expands through deep learning in the collection and storage of information.

[0143] Now, let's proceed to the details of the information control function 10 shown in Figure 6. As shown in the figure, the information control function 10 includes a vehicle identification function 110 and a fare collection function 120.

[0144] The vehicle identification function 110 comprises a wireless detection information processing function 111 and an image detection information processing function 112. The wireless detection information processing function 111 processes wireless detection information acquired via the wireless detection function S, and the image detection information processing function 112 processes image detection information acquired via the image detection function V.

[0145] According to regulations, the wireless detection information in the ETC system includes the vehicle type classification and license plate number. Therefore, among the detected wireless detection information, vehicles that match the vehicle type classification and license plate number indicated by the image detection information in the image capture results are identified as specific vehicles.

[0146] This allows us to recognize that the specific vehicle identified here has passed through the wireless communication area where the wireless detection information was acquired.

[0147] Furthermore, in the case of imaging, the number of vehicles being imaged is not a problem. Therefore, it may be possible to detect imaging information for multiple vehicles simultaneously, and in that case, it may be possible to identify multiple specific vehicles that have passed through the wireless communication area all at once.

[0148] Here, the detected and acquired wireless detection information is stored in the wireless detection information storage function 1111 either in its original state or in a listed state. Similarly, the imaging detection information is also stored in the imaging detection information storage function 1121 either in its original state or in a listed state.

[0149] The detected wireless detection information and image detection information may be stored in the information storage function 40, which is a unique memory device within the central control function C, or they may be stored in a database memory device such as a cloud via the network function N.

[0150] Furthermore, as stated above, "among the wireless detection information that has been detected, vehicles that match the vehicle (vehicle type and license plate number) indicated by the image detection information in the image capture results are identified as specific vehicles," which suggests that the acquisition of wireless detection information comes first, followed by the acquisition of image detection information. However, the order can be reversed, and it would also be acceptable to say, "among the image detection information that has been detected, vehicles that match the detected and acquired wireless detection information (vehicle type and license plate number) are identified as specific vehicles."

[0151] Therefore, both the wireless detection information processing function 111 and the image detection information processing function 112 have a "vehicle identification function" that identifies a specific vehicle by referring to the information acquired by the other and matching it with the information acquired by itself, and perform a double check (match check) of the resulting "specific vehicle" as needed.

[0152] In the vehicle identification function 110, once the identification of a specific vehicle is complete, the toll collection function 120 then performs a predetermined collection process for collecting the usage fee from the specific vehicle. Since the vehicle has been identified and the wireless communication area (e.g., toll booth) that the specific vehicle has passed through is also known, the usage fee can be calculated and the predetermined collection process, such as billing, can be performed.

[0153] The fare collection function 120 includes a reference information processing function 121 and a fare collection information processing function 122, as shown in the figure.

[0154] The reference information processing function 121 includes a user information processing function 1211 and a card information processing function 1212.

[0155] The user information processing function 1211 acquires and processes (investigates and records) vehicle-related information, mainly related to the user's vehicle, such as the onboard unit management number, vehicle information (license plate, vehicle length, maximum height, vehicle width, maximum load capacity, vehicle weight, type of vehicle, purpose, passenger capacity, engine displacement, fuel type), etc., in order to calculate the usage fee.

[0156] The card information processing function 1212 acquires and processes (investigates and records) the user's card-related information (card number, expiration date, etc.).

[0157] Vehicle-related information and card-related information here may be stored in the information storage function 40, which is a unique storage device, or they may be stored in a storage device for a database such as a cloud via the network function N.

[0158] The receipt information processing function 122 includes a fee calculation processing function 1221 and a fee collection processing function 1222.

[0159] The fee calculation processing function 1221 calculates the usage fee to be charged to the user (owner of the vehicle) based on information about the specific vehicle obtained by the vehicle identification function 110, such as the type of vehicle, the entrance and exit points in the case of a toll road, as well as vehicle-related information and card-related information obtained by the reference information processing function 121, and sometimes specific discount information related to these.

[0160] The fee collection processing function 1222 processes invoices to credit card companies, etc., in order to collect the usage fees calculated by the fee calculation processing function 1221 described above.

[0161] As described above, the information processing function [information processing system] 1B of this embodiment performs a predetermined collection process for collecting usage fees from a specific vehicle. That is, since the vehicle is identified and the wireless communication area (e.g., toll booth) that the specific vehicle has passed through is also determined, the usage fee can be calculated and a predetermined collection process such as billing can be performed.

[0162] As mentioned above, in this case, there is no need to "narrow the wireless communication range." On the contrary, in order to enable the use of a general-purpose, low-directional, and inexpensive wide-area antenna, it is better to aim for "widening the wireless communication range," which is based on the exact opposite idea.

[0163] Therefore, there is no need to wait for technological advancements to narrow the wireless communication range, and the high costs associated with adopting advanced technologies are avoided. Furthermore, by combining image detection with widening the wireless communication range, the problem of false detection can also be resolved.

[0164] Therefore, according to this embodiment, without waiting for further technological advancements, and based on the ingenious combination of current technologies, it is possible to eliminate false detections without requiring antenna directivity for narrowing the wireless communication range.

[0165] Furthermore, in this case, the wireless detection information includes card information from a card installed inside the target vehicle, so the wireless detection function can be used to acquire (detect) the card information.

[0166] Furthermore, in this case, by designating the area of ​​the toll booth on the toll road as a wireless communication area, it can be applied to the collection of usage fees on the toll road.

[0167] Furthermore, by installing the imaging detection function on the roadside of the toll road lanes and including the lanes on the toll road in the imaging detection area, the imaging detection function installed on the roadside of the toll road lanes can capture images of the lanes on the toll road as the imaging detection area, thereby enabling the acquisition of imaging detection information from vehicles on the toll road.

[0168] In the example above, we mainly explained the application of this case to toll roads, but various other applications are also conceivable.

[0169] [3. Specific examples of applicable facilities] Figure 7 is an explanatory diagram showing a specific example of a facility to which the "information processing function" of the embodiment is applied.

[0170] The first example shows an application to the toll roads described above, but here the explanation is divided into cases for toll roads with a single fee and toll roads that charge based on distance.

[0171] In the case of a toll road with a single toll, the collection of usage fees can be reliably performed by ensuring that the wireless communication area and the image detection area include a predetermined passage area that all vehicles pass through at least once, and by reliably acquiring wireless detection information and image detection information when each vehicle passes through that predetermined passage area.

[0172] Therefore, in the case of a single toll, toll booths are often installed at either the entrance or exit of the toll road, and ETC, which has a wireless detection function, is often set up near the area where vehicles pass through the toll booth.

[0173] However, in this case, the wireless communication area is set (installed) in such a way that each vehicle passing through the toll booth must enter that area at least once, and the wireless detection function can detect wireless detection information, thus "widening the wireless communication area." This allows the use of a general-purpose, low-directional, and inexpensive wide-area antenna.

[0174] Furthermore, the image detection area is configured such that each vehicle passing through the tollbooth enters the area at least once, allowing for the detection of image detection information. This is achieved by setting the installation locations and number of image sensors V0~ of the image detection function V. In other words, "optimization of the installation conditions for the image detection function" is achieved.

[0175] These measures allow for a wider detection range, rather than the narrow range of conventional technologies, by utilizing a general-purpose wide-area antenna to reliably detect wireless detection information from each vehicle. In other words, these measures also enable "specific and optimized detection of specific vehicles."

[0176] In this case, it is possible to avoid waiting for technological advancements to narrow the wireless communication area, and also to avoid the high costs associated with adopting new technologies. Furthermore, it becomes possible to reliably perform wireless detection, which can also effectively eliminate false detections. In other words, this also contributes to the rationalization of toll collection.

[0177] The following example shows a toll road where distance-based (section-based) charges are collected. The wireless communication area includes an area for detecting wireless detection information of all vehicles passing through any one entrance, ensuring that wireless detection information is reliably acquired when each vehicle passes through. The vehicle identification area includes an area for detecting separate detection information of all vehicles passing through any one exit, ensuring that separate detection information (e.g., image detection information) is reliably acquired when each vehicle passes through, ensuring that specific vehicles are identified. This allows for the calculation of usage fees according to the vehicle type and travel section, and the collection of appropriate usage fees. The entrance area may also include an area for detecting separate detection information, ensuring that separate detection information (e.g., image detection information) is reliably acquired when each vehicle passes through.

[0178] Alternatively, by including an area that detects separate detection information for all vehicles passing through any one entrance, and ensuring that separate detection information (e.g., image detection information) is reliably acquired when each vehicle passes through, and by including an area in the vehicle identification area that detects wireless detection information for all vehicles passing through any one exit, the identification of a specific vehicle can be reliably performed. This allows for the calculation of usage fees according to the vehicle type and travel section, and enables the collection of appropriate usage fees.

[0179] In this example, wireless communication areas and imaging detection areas are often set up to correspond to the entrance and exit toll booths. In this case as well, by setting a wide wireless communication area, the use of a general-purpose wide-area antenna can be used to "widen the wireless communication area" and "optimize the installation conditions for the imaging detection function," thereby also achieving "optimal identification of specific vehicles" and "optimal toll collection." As a result, false detections and high costs can be eliminated without waiting for technological advancements.

[0180] The following example shows an application to a parking lot. By including the area of ​​the parking lot entrance in the wireless communication area, wireless detection information can be collected. By including the area of ​​a predetermined location at the parking lot exit in the image detection area, the area at the predetermined location at the parking lot exit can be imaged as an image detection area. This allows the vehicle that has been previously identified by the wireless detection information to be identified as a specific vehicle, and the fee can be calculated according to the dwell time, etc., and the usage fee can be collected at the toll booth area at the parking lot exit. Alternatively, by including an area for detecting other detection information at the entrance, it is possible to reliably acquire other detection information (e.g., image detection information) when each vehicle passes through.

[0181] Alternatively, as separate detection information, an area at a predetermined location at the parking lot entrance can be imaged as an imaging detection area, and the area at the parking lot exit can be included in the wireless communication area as a vehicle identification area. By collecting wireless detection information, the vehicle can be identified as a specific vehicle, and a fee can be calculated according to the dwell time, etc., and the usage fee can be collected at the toll booth area at the parking lot exit.

[0182] In this example as well, the wireless communication area and imaging detection area corresponding to the entrance and exit are set to wide areas, thereby achieving "wider wireless communication area" and "optimization of installation conditions for imaging detection function," as well as "optimization of specific vehicle identification" and "optimization of toll collection." As a result, a general-purpose wide-area antenna can be used, and false detection and high costs can be eliminated without waiting for technological advancements.

[0183] The following example illustrates the application to a limited area in a service area (SA), parking area (PA), or other tourist destination. In this example, the basic idea is that the collection of vehicle information via radio detection only needs to collect radio detection information from all vehicles that enter the area, so the installation location of the detection device is not limited. In any case, it collects information from at least all vehicles that enter the area, so even if extra radio detection information is collected from vehicles that pass nearby outside the area, it does not pose a problem as long as the imaging device does not detect them.

[0184] Therefore, although the diagram shows "each entrance," detecting at "each entrance" satisfies the condition of "all vehicles that enter the area," so this is merely an example and not limited to this.

[0185] On the other hand, because it is necessary to individually and reliably detect the vehicles providing the service, the imaging detection area is described as "each facility" in order to reliably image and detect the vehicles receiving the service.

[0186] In this example as well, the above-mentioned settings allow for "expansion of the wireless communication range" and "optimization of the installation conditions for the imaging detection function," as well as "optimization of the identification of specific vehicles," thereby aiming to eliminate false detections and high costs without waiting for technological advancements.

[0187] In this example, it would also be possible to link the charges for various services within this area, such as meal provision and souvenir sales, and collect charges accordingly. This would allow for a single settlement where the service usage fees at service bases are included in the usage fees for vehicles subject to charges within the wireless communication area. In this case, "fairness in charge collection" would also be achieved.

[0188] Furthermore, as mentioned above, since vehicle-related information such as vehicle registration information can be obtained based on wireless detection information, it is possible to link the service to provide services tailored to the characteristics of the vehicle, such as whether the vehicle is from a nearby or distant location across the country, and whether it is for private or commercial use.

[0189] Furthermore, in this embodiment, the wireless detection function may be configured to communicate simultaneously or sequentially with multiple vehicles in the wireless communication domain to collect wireless detection information from each vehicle.

[0190] In this case, the wireless detection function can communicate simultaneously or sequentially with multiple vehicles in the wireless communication domain to collect wireless detection information from each vehicle, thus enabling the acquisition of wireless detection information from each vehicle through simultaneous or sequential communication.

[0191] Furthermore, the wireless detection information acquisition function may also include a wireless detection information storage function capable of storing a list of wireless detection information from one or more vehicles.

[0192] In this case, the wireless detection information acquisition function is equipped with a wireless detection information storage function that can store a list of wireless detection information for one or more vehicles. Subsequently, the vehicle identification function can refer to the stored list to identify a specific vehicle.

[0193] Furthermore, the imaging detection function may be configured to detect imaging detection information of vehicles present in an imaging detection area, where an imaging detection area is defined as an area where vehicles stopped in or passing through an area where usage fees can be collected.

[0194] In this case, the imaging detection function defines the imaging detection area as the area in which vehicles that have stopped or are passing through the area where usage fees can be collected can be imaged, and is capable of detecting imaging detection information of vehicles that are present in that imaging detection area. Therefore, imaging detection information of vehicles that have stopped or are passing through the area in which usage fees can be collected can be reliably acquired.

[0195] Furthermore, the vehicle identification function may be configured to identify one vehicle as the designated vehicle from among one or more vehicles listed in the wireless detection information, which matches the vehicle detected by the image detection information.

[0196] In this case, the vehicle identification function can identify one vehicle from a list of one or more vehicles whose wireless detection information matches the vehicle detected by the image detection information, thus reliably identifying the specific vehicle by referring to the list.
