Description

Technical Field

[0001] The present invention relates to the field of data processing technology, in particular to a method, device, electronic equipment and storage medium for investigating toll evasion on expressway gantries. Background Art

[0002] At present, changing the vehicle model is a relatively common means of evading fees. The main ways of evading fees by changing the vehicle model are to use forged materials to achieve a large vehicle with a small label, a truck with a passenger label, or a bus with a cargo label when the vehicle is issued, and to change the vehicle model during the passage, such as using / changing the trailer.

[0003] Existing methods simply determine the model of passing vehicles by analyzing their historical traffic patterns. This is not accurate enough, and the data on suspected toll evaders filtered out is not precise enough. In addition, the number of axles of a trailer can change while traveling on the highway, and the number of axles currently traveling cannot be determined by analyzing the vehicle's historical traffic patterns. Therefore, it is impossible to detect toll evasion by changing the vehicle model during travel.

[0004] Therefore, the existing technology needs to be improved. Summary of the Invention

[0054] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0055] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0056] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0057] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0058] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0059] The highway gantry toll evasion inspection method provided by this application can be applied to Figure 1 In the application environment shown, the highway gantry toll evasion inspection method is applied to a highway gantry toll evasion inspection device. The client of the highway gantry toll evasion inspection device is configured at terminal 102, and the server is configured at server 104. The highway gantry toll evasion inspection method is completed by the interaction between terminal 102 and server 104.

[0060] The terminal 102 and the server 104 can communicate via a network.

[0061] Among them, the terminal 102 can be but is not limited to various personal computers, laptops, smart phones, tablet computers and portable wearable devices. The terminal 102 must have the function of obtaining image information or video information of a vehicle passing through a highway gantry; obtaining vehicle feature information of the vehicle and the vehicle's passing transaction information based on the image information or video information of the vehicle passing through the highway gantry; obtaining the vehicle's evasion data based on the vehicle feature information of the vehicle and the vehicle's passing transaction information; and automatically collecting the vehicle's evasion evidence chain based on the vehicle's evasion data. The server 104 can be implemented using an independent server or a server cluster composed of multiple servers.

[0062] In one embodiment, Figure 2 As shown, a method for checking toll evasion on highway gantry is provided. This embodiment mainly applies the method to Figure 1 The terminal 102 in the highway gantry toll evasion inspection method includes:

[0063] Step 210: Obtain image or video information of vehicles passing through the highway gantry. Specifically, a highway gantry is a gantry-shaped device installed at a set location on the highway. It is equipped with multiple sensors, cameras, etc. The sensors sense the arrival of vehicles at a set distance, and the cameras capture images or videos of the vehicles. The cameras on the highway gantry are generally located in front of the vehicle's direction of travel. When the sensors detect that a vehicle has reached the set distance, the cameras start to continuously capture or record the vehicle, thereby capturing image or video information of the vehicle passing through the highway gantry. It should be noted that image or video information of the vehicle passing through the highway gantry is also captured when the vehicle passes through the entrance or exit of the highway. The image information of the vehicle captured at the entrance or exit is also used to identify the vehicle's license plate number, model, color, etc. However, since cameras and other equipment are inevitably present at the entrance or exit of the highway, this application does not specifically emphasize the acquisition of image or video information of vehicles at the highway entrance or exit. It is assumed that such equipment is present and that image or video information of the vehicle is captured.

[0064] Specifically, in one embodiment of the present application, obtaining image information or video information of a vehicle passing through a highway gantry includes:

[0065] A gantry structure is set up on a set section of the highway, and multiple image acquisition devices and sensor devices are set up on the gantry; the sensor devices and image acquisition devices can be used in combination, for example, one image acquisition device is matched with one sensor device, or an image acquisition device and a sensor device are set up above each lane, and each sensor device and image acquisition device is responsible for one lane.

[0066] According to the above, multiple image acquisition devices and sensor devices are set on the gantry to obtain the vehicle traffic status information sensed by the sensor device; specifically, the function of the sensor device is to detect vehicles traveling from a distance, and the sensor device is used to detect the distance information of the vehicle, such as the distance sensor. When the vehicle reaches the detection distance set by the sensor device, the sensor device can detect the vehicle.

[0067] Based on the vehicle traffic status information sensed by the sensor device, the image capture device is activated to capture image or video information of the gantry on the highway where the vehicle is passing. Specifically, when the sensor device detects an approaching vehicle, the image capture device is activated and, depending on the layout of the image capture device, captures an image of the vehicle or records video of the vehicle within a specified road section using either a fixed capture method or a moving image capture device angle.

[0068] Specifically, the function of the sensor device is to obtain the distance of the vehicle. The sensor device can be a speed sensor, a distance sensor or a sound sensor, etc. The sensor device can detect a moving vehicle at a set distance and control the image acquisition device to start collecting vehicle images or video information. It should be noted that in order to save resources and improve efficiency, the image acquisition device may not work full-time. For example, when there is no vehicle passing, the image acquisition device may be in a dormant state. When the sensor device detects a vehicle passing within a set distance range, the image acquisition device will be activated and collect vehicle image information or vehicle video information within a set time length or a set distance length.

[0069] Step 220: Acquire vehicle feature information of the vehicle and the vehicle's passing transaction information based on the image information or video information of the vehicle passing through the highway gantry.

[0070] Specifically, vehicle feature information is used to identify the vehicle and determine its uniqueness. For example, the vehicle model, color, and category can be obtained by searching the corresponding database through the license plate number. Vehicle categories include large trucks, large buses, passenger cars with more than 7 seats, passenger cars with less than 7 seats, etc. Vehicle traffic transaction information refers to the billing information generated for the vehicle when the vehicle passes through the entrance and exit and each highway gantry. For example, when the vehicle enters the highway entrance, the vehicle is charged by scanning the license plate. Then, when driving on the highway, the vehicle is identified and charged each time it passes a highway gantry. At the highway exit, the vehicle is finally charged for the highway section. These billing information are the vehicle's traffic transaction information. It should be noted that, for example, if a vehicle uses a duplicate license plate or a fake license plate, or uses inconsistent license plates, or changes a license plate that is inconsistent with the vehicle model while the vehicle is driving on the highway, or adds or removes a trailer while the vehicle is driving on the highway, these cannot be charged using the existing toll collection system. It is necessary to combine the process of the vehicle passing through the highway gantry and whether the vehicle information identified by the highway gantry each time is consistent with the vehicle information at the vehicle entrance and exit. Through these consistency judgments, it is ensured that all states of the vehicle during driving are consistent to ensure that the vehicle is charged accurately.

[0071] Specifically, in one embodiment of the present application, obtaining the vehicle characteristic information and the vehicle passing transaction information based on the image information or video information of the vehicle passing through the highway gantry includes:

[0072] Based on the image information or video information of the vehicle passing through the highway gantry, panoramic image information of the vehicle when passing through the highway gantry is obtained; specifically, the panoramic image information of the vehicle can be obtained by image stitching or the like. In an embodiment of the present application, the panoramic image information of the vehicle when communicating with the highway gantry is obtained by using relevant algorithms of the prior art.

[0073] Based on the panoramic image information of the vehicle when passing through the highway gantry, the vehicle characteristic information of the vehicle is obtained, and the vehicle characteristic information includes the vehicle's license plate number information, color information, vehicle model information, and axle number information; specifically, through image recognition technology, the vehicle characteristic information of the vehicle can be obtained through the panoramic image of the vehicle. These vehicle characteristic information include the license plate number, vehicle color, vehicle model, and number of axles. The corresponding database can be queried through the license plate number to obtain the vehicle information corresponding to the license plate number, and then through the identification and comparison of the vehicle model, number of axles and vehicle color, it can be determined whether the vehicle characteristic information identified by the highway gantry is consistent with the vehicle characteristic information stored in the original database corresponding to the license plate number. If they are consistent, it means that the vehicle is legal and normal. If they are inconsistent, it is necessary to make a judgment through other highway gantries.

[0074] Based on the vehicle characteristic information of the vehicle, the entrance and exit information and all the gantries information passed by the vehicle on the highway are obtained; specifically, since the speed of the vehicle on the highway is relatively fast, and at the same time, the vehicle images captured by the image acquisition equipment also have certain errors, therefore, the entrance and exit information passed by the vehicle on the highway, that is, all the gantries information, refers to all highway gantries that can correctly identify the license plate number and the vehicle characteristic information stored in the database corresponding to the license plate number is consistent with the vehicle characteristic information identified by the highway gantries. If they are inconsistent, they need to be eliminated.

[0075] The vehicle's access transaction information is obtained based on the information about the entrances and exits and all gantries that the vehicle passes through on the highway. Specifically, within a collection of highway entrances and exits and highway gantries that can correctly identify vehicle characteristic information, the charging identification of each highway gantry is used to indicate whether the vehicle is being charged normally, as well as the vehicle charging identification at the highway entrance and exit, thereby forming a transaction flow of the vehicle at the highway entrances and exits, as well as the vehicle at the highway gantries. By summarizing these transaction flows, the vehicle's access transaction information can be obtained.

[0076] Specifically, in one embodiment of the present application, obtaining the entrance and exit information and all gate frame information passed by the vehicle on the highway based on the vehicle characteristic information of the vehicle includes:

[0077] Based on the vehicle characteristic information of the vehicle, the entrance and exit information passed by the vehicle on the expressway is obtained; specifically, when the vehicle enters the entrance of the expressway, the vehicle will register the entrance through which the vehicle enters the expressway based on the vehicle characteristic information of the vehicle, and when the vehicle exits the expressway, the vehicle will register the exit through which the vehicle exits the expressway. The entrances and exits of the expressway passed by the vehicle are important bases for charging the vehicle. At the same time, the vehicle characteristic information obtained at the entrances and exits of the expressway is an important basis for determining whether the vehicle has evaded tolls.

[0078] Based on the entrance and exit information passed by the vehicle on the expressway, information on all gantries that the vehicle needs to pass through after passing through the entrance and exit is obtained; specifically, since the expressway gantries that the vehicle needs to pass through when traveling on the expressway can be obtained through the vehicle at the entrance and exit of the expressway, all these expressway gantries that the vehicle needs to pass through are the expressway gantries set up on the expressway sections at the entrance and exit.

[0079] Based on the information of all the gantries that the vehicle needs to pass through after passing through the entrance and exit, the vehicle information monitored by all the gantries that the vehicle needs to pass through is obtained; specifically, after obtaining all the gantries that the vehicle needs to pass through, the vehicle information monitored by all the gantries can be checked. It should be noted that the vehicle information monitored by all the gantries is not necessarily completely consistent. For example, some may monitor inconsistent vehicle models, some may monitor inconsistent vehicle colors, and some may monitor inconsistent axle numbers, etc. The main reason for the inconsistency is that the vehicle tries to evade tolls. For example, if the vehicle is dropped or replaced during driving on the highway, the monitored vehicle model will be inconsistent. For example, if the license plate of the vehicle is replaced during driving on the highway, such as a truck with a passenger license plate or a large vehicle with a small license plate, the monitored vehicle model and axle number will be different.

[0080] Based on the vehicle information detected by all the gantries that the vehicle is required to pass through, information about all gantries that have actually detected the vehicle is obtained. Specifically, by obtaining information about all the highway gantries that the vehicle is required to pass through when traveling on the highway, it is possible to determine which gantries have actually detected the vehicle and which have not correctly identified the vehicle. The reason for not correctly identifying the vehicle may be that the vehicle has evaded tolls.

[0081] Specifically, in one embodiment of the present application, obtaining the vehicle's traffic transaction information based on the entrance and exit information and all gate frame information passed by the vehicle on the highway includes:

[0082] Based on the entrance and exit information and all gantries information passed by the vehicle on the highway, the toll signs of the vehicle at the entrance and exit, as well as the toll signs of all gantries passed by the vehicle on the highway are obtained; specifically, after the vehicle passes through the entrance and exit and the highway gantry, the vehicle's vehicle characteristic information will be identified, and then the vehicle after the vehicle characteristic information is identified will be marked with a toll sign, indicating that the vehicle passing through the highway entrance and exit and the highway gantry has been charged. On the one hand, it prevents undercharging or non-charging, and on the other hand, it makes charging more reasonable by continuously setting toll signs.

[0083] Based on the toll signs of the vehicle at the entrances and exits and the toll signs of all the gantries passed by the vehicle on the highway, the transaction information of the vehicle at the entrances and exits and all the gantries passed by the vehicle is obtained; specifically, after the vehicle completes the setting of the toll sign, the transaction information of all toll signs can be counted based on the toll signs of the vehicle at the entrances and exits, and after the highway gantry identifies the vehicle and completes the setting of the toll sign.

[0084] Based on the transaction information of the vehicle at the entrances and exits and all the gates it passes through, the transaction information that is inconsistent with the vehicle characteristic information of the vehicle is obtained and deleted; specifically, when the highway gantry identifies the vehicle characteristic information, the identified vehicle characteristic information may be inconsistent with the vehicle's real vehicle characteristic information due to the vehicle deliberately evading the fee. At this time, it is necessary to delete the toll mark of the vehicle on the highway gantry with inconsistent vehicle characteristic information to ensure the consistency of the transaction information.

[0085] The vehicle's passing transaction information is obtained based on the result of deleting the transaction information that is inconsistent with the vehicle characteristic information of the vehicle.

[0086] Step 230: Acquire the toll evasion data of the vehicle based on the vehicle characteristic information of the vehicle and the vehicle's travel transaction information.

[0087] Specifically, after the vehicle's travel transaction information is calculated and counted, it is possible to obtain which highway gantries charged the vehicle and which did not when the vehicle was traveling between the entrances and exits of the highway, what was the vehicle characteristic information identified by the highway gantries that did not charge, and how it differed from the actual vehicle characteristic information of the vehicle, etc. Through these analyses and judgments, the vehicle's toll evasion data, that is, how the vehicle evaded the toll, can be determined.

[0088] Specifically, in one embodiment of the present application, obtaining the toll evasion data of the vehicle based on the vehicle characteristic information of the vehicle and the vehicle's pass transaction information includes:

[0089] Based on the vehicle's characteristic information and the vehicle's traffic transaction information, the time information and toll sign time information of the highway gantry detecting the passing vehicle, as well as the license plate number and license plate color information of the passing vehicle, are obtained. When a vehicle passes through the highway gantry, the image capture device captures the vehicle's image or video information and marks the current capture time, i.e., when the vehicle's travel image was captured. After the highway gantry captures the image, it performs vehicle feature recognition on the vehicle in the image and marks the vehicle for toll based on the recognition result. At this time, the toll marking of the vehicle also records the time information, i.e., when the vehicle toll was calculated. Under normal circumstances, there will be a time difference between the image recognition and toll marking of the same highway gantry. However, due to the high data processing capabilities of the equipment, this time difference is not very long. However, if the image recognition and toll marking are not generated by the same highway gantry, the time difference can be very long. For example, if the first highway gantry recognizes the vehicle's characteristics while the second highway gantry marks the vehicle for toll, the time difference can be very long.

[0090] Determine the difference between the time information of the highway gantry detecting the passing vehicle and the time information of the toll sign and the set threshold, as well as the consistency between the license plate number information and license plate color information of the passing vehicle detected by the highway gantry and the vehicle feature information detected at the entrance and exit. Specifically, the time threshold is a reasonable time difference between the statistical vehicle feature recognition and the toll sign. This time difference is mainly related to the data processing capability of the chip. If the time difference between the time information of the highway gantry detecting the passing vehicle and the time information of the toll sign is large, it means that the same highway gantry is not monitoring the time information of the passing vehicle and the time information of the toll sign at the same time. Instead, one highway gantry monitors the time information of the passing vehicle, and another highway gantry counts the time information of the toll sign. This time difference must be caused by the inconsistency of the vehicle feature information of the vehicle. Inconsistency of the vehicle feature information indicates that the vehicle is evading tolls.

[0091] When the difference between the time information of the highway gantry detecting a passing vehicle and the time information of the toll sign is less than a set threshold, and the license plate number and color information of the passing vehicle detected by the highway gantry are consistent with the vehicle characteristic information detected at the entrance and exit, the vehicle's toll evasion data is obtained. Specifically, the determination of whether a vehicle has engaged in toll evasion is made only when two conditions are met: first, the difference between the time information of the highway gantry detecting a passing vehicle and the time information of the toll sign is less than a set threshold, and second, the license plate number and color information of the passing vehicle detected by the highway gantry are consistent with the vehicle characteristic information detected at the entrance and exit.

[0092] Specifically, in one embodiment of the present application, when the difference between the time information of the highway gantry detecting a passing vehicle and the time information of the toll sign is less than a set threshold, and the license plate number information and license plate color information of the passing vehicle detected by the highway gantry are consistent with the vehicle feature information detected at the entrance and exit, obtaining the toll evasion data of the vehicle includes:

[0093] When the difference between the time information of the highway gantry detecting the passing vehicle and the time information of the toll sign is less than the set threshold, and the license plate number information and license plate color information of the passing vehicle detected by the highway gantry are consistent with the vehicle feature information detected at the entrance and exit,

[0094] If the vehicle type information detected by the highway gantry and the vehicle type information detected by the vehicle passing through the entrance and exit are inconsistent with the vehicle type, obtaining the toll evasion data of the vehicle;

[0095] Alternatively, if the axle number information detected by the vehicle passing through the highway gantry and the axle number information detected by the vehicle passing through the entrance and exit are inconsistent with the axle number of the vehicle, obtaining the toll evasion data of the vehicle;

[0096] Alternatively, if the toll identification information of the vehicle on the highway gantry and the toll identification information of the vehicle at the entrance and exit are inconsistent with the actual toll identification information of the vehicle, the toll evasion data of the vehicle is obtained.

[0097] Assuming that the vehicle is a truck and the number of axles of the vehicle is greater than the set value, if the number of axles marked on the toll sign of the highway gantry is less than the number of axles of the vehicle, and the number of axles of the vehicle counted at the entrance and exit of the highway is also less than the actual number of axles, then it is determined that the vehicle is suspected of evading highway tolls by means of dropping / switching. If the number of axles marked on the toll sign of the highway gantry is less than the number of axles of the vehicle, but the number of axles of the vehicle counted at the entrance and exit of the highway is consistent with the actual number of axles, then it should not be determined that the vehicle is suspected of evading highway tolls.

[0098] If the number of axles of the vehicle marked on the toll sign of the highway gantry is consistent with the number of axles of the vehicle, but the number of axles of the vehicle counted at the entrance and exit of the highway is inconsistent with the actual number of axles, it is also determined that the vehicle is suspected of evading highway tolls by means of dropping / changing the axles.

[0099] Specifically, for example, when the vehicle type marked on the toll sign of the highway gantry, the fixed-fee vehicle type at the highway entrance and exit, and the vehicle type are all passenger cars, trucks, or special-purpose vehicles, if the charge for the vehicle type marked on the toll sign of the highway gantry is less than the charge for the vehicle type, and the charge for the fixed-fee vehicle type at the highway entrance and exit is less than the charge for the vehicle type, then the vehicle is deemed to have suspected evasion of highway tolls by using the method of "large vehicle, small sign" for this passage; if the charge for the vehicle type marked on the toll sign of the highway gantry is less than the charge for the vehicle type, but the charge for the fixed-fee vehicle type at the highway entrance and exit is equal to the charge for the vehicle type, then the vehicle should not be deemed to have suspected evasion of highway tolls by this passage; if the charge for the vehicle type marked on the toll sign of the highway gantry is equal to the charge for the vehicle type, but the charge for the fixed-fee vehicle type at the highway entrance and exit is less than the charge for the vehicle type, then the vehicle is deemed to have suspected evasion of highway tolls by using the method of "large vehicle, small sign" for this passage.

[0100] Step 240: automatically collect the vehicle's fare evasion evidence chain based on the vehicle's fare evasion data.

[0101] Specifically, for vehicles suspected of toll evasion, the vehicle's highway entrance and exit transaction data, highway gantry transaction data, license plate recognition data, captured image / video data, and panoramic images of the vehicle obtained through image processing are automatically collected through license plates and travel times to form a corresponding chain of evidence.

[0102] The highway gantry toll evasion inspection method of the present application obtains image information or video information of a vehicle passing through the highway gantry; obtains vehicle characteristic information and vehicle passage transaction information of the vehicle based on the image information or video information of the vehicle passing through the highway gantry; obtains toll evasion data of the vehicle based on the vehicle characteristic information and vehicle passage transaction information; and automatically collects the toll evasion evidence chain of the vehicle based on the toll evasion data of the vehicle. The present application can accurately obtain the vehicle model and number of axles, and determine whether the vehicle has evaded tolls based on the model and number of axles, thereby improving the accuracy of the screening of suspected vehicle evasion data and solving the problem of failing to detect toll evasion behaviors caused by changing the vehicle model during vehicle passage.
