Embodiment one: referring to fig. 1, fig. 1 is a flow chart of an ETC checkout security control method according to an embodiment of the invention. As shown in fig. 1, the ETC checkout security control method according to the embodiment of the invention includes the following steps: extracting bayonet structure data and vehicle data according to the first vehicle image data; detecting a target vehicle from the bayonet structure data and the vehicle data; and controlling the working state of ETC equipment according to the detection result of the target vehicle.

In this step, the ETC devices of the prior art are all in a normally open state, which results in an easy to be rubbed ETC by him, i.e. the technical problems referred to in the foregoing background art. In view of this, the present invention uses the driving image captured by the vehicle-mounted image capturing device to analyze the front gate structure data and the vehicle data, so that it is possible to analyze which vehicles are suspected target vehicles with ETC, and correspondingly switch the working state of the ETC device according to the detection result, for example, when it is analyzed that a certain vehicle in front is suspected, the ETC device may be switched to the off state (the device itself is powered off, or the reading module of the charging card is disconnected). Therefore, the scheme of the invention can obtain the target vehicle with the scratch ETC suspicion based on the analysis of the driving image data, and further pertinently switch the working state of the ETC equipment, thereby achieving the purpose of avoiding the ETC equipment from being scratched.

In addition, the scheme of the invention can be applied to expressway scenes, and other application scenes such as scenic spots, communities, charging bayonets of parks and the like can be easily obtained by a person skilled in the art.

It should be noted that, the scheme of the present invention may be implemented in the ETC device itself, and accordingly, the ETC device has a processing module and a communication module in addition to the original settlement-related module, where the communication module is used to connect with the vehicle-mounted image acquisition device to receive the driving image data. Of course, the communication and processing functions described above may be implemented in the vehicle itself, that is, by a processing terminal of a vehicle computer, for example, provided in the vehicle itself. In addition, the method can also be implemented on various types of in-vehicle mobile terminals, such as mobile phones, computers, tablet computers, wearable devices, virtual reality devices and the like, and detailed description thereof is omitted.

In this step, because ETC charging/checkout is performed at the gate (i.e. the toll gate), the present invention determines whether the front is about to pass the gate by comparing the positioning data of the vehicle with the high-precision map, at this time, the acquisition of the second traffic image data may be triggered, whether the gate is actually present is determined, and the gates that have been removed but the high-precision map has not been updated are excluded, and accordingly, the acquisition of the first traffic image data may be triggered when the gate is identified based on the second traffic image data. By the arrangement, invalid identification of the first driving image data can be avoided, and the data processing amount is reduced.

When the vehicle is detected, the suitable first driving image data acquisition time can be calculated according to the distance between the vehicle and the speed of the vehicle.

In this step, the running image data may be acquired by the above-described two kinds of vehicle-mounted image acquisition apparatuses, wherein the vehicle-mounted camera may be a camera equipped at the time of shipment of the vehicle, for example, a camera for running records, driving assistance, and the like.

In this step, a vehicle to be rubbed ETC generally waits in a region in front of the ETC channel, and after the ETC device of the following vehicle is identified, the vehicle quickly drives into the corresponding ETC channel, thereby rubbing ETC. Meanwhile, the behavior characteristics of different vehicles in the process of executing the ETC are different, and the ETC behavior database is difficult to build in an enumeration mode. Therefore, the depth recognition model is built, and the depth recognition model is trained by utilizing the behavior characteristics and the bayonet structure characteristics of the real vehicle rubbing ETC scene obtained through various ways, so that the relation among the vehicle data, the bayonet structure data and the suspicion index of the rubbing ETC can be built.

The depth recognition model may be built by using various algorithms in the prior art, for example, a hybrid network consisting of a recurrent neural network (Recurrent Neural Network, RNN), a convolutional neural network (Convolutional Neural Network, CNN), long-term short-term memory (Long-Short Term Memory, LSTM) and CNN, and the specific building method is not described herein.

In this step, the driving behavior of the vehicle in front of the etc. channel may be "abnormal" due to various reasons, for example, the ETC reader or the barrier may fail, so that the candidate vehicle stays in front of the etc. channel, and at this time, the first suspicion index output by the depth recognition model may be too high, which may cause erroneous judgment to the candidate vehicle. In order to solve the problem, the method further obtains personnel data related to the inter-lane isolation roadbed structure data, and corrects the first suspicion index based on the personnel data, so as to obtain a more accurate second suspicion index.

In this step, when the ETC reader or the barrier gate fails, the candidate vehicle is retained in front of the ETC channel, and at this time, if a worker wearing a related uniform appears on the lane separation roadbed, the authenticity of the failure condition can be confirmed, and accordingly, the suspicion index of the candidate vehicle should be adjusted down, or otherwise, adjusted up or not.

In this step, when the foregoing malfunction does exist, the candidate vehicle may output a malfunction alert by means of a whistle before the relevant staff member is treated. In view of this phenomenon, when no relevant staff is detected, the invention further judges whether the candidate vehicle is whistling, if so, the authenticity of the fault is judged to be high, and accordingly, the suspicion index of the candidate vehicle is required to be adjusted down, otherwise, the suspicion index of the candidate vehicle is required to be adjusted up or not.

It should be noted that, the presence of the staff member is more reliable than the judgment of the fault authenticity by the whistle, so the third correction coefficient should be set to be larger than the first correction coefficient, and the fourth correction coefficient should be larger than the second correction coefficient.

Embodiment two: referring to fig. 2, fig. 2 is a schematic structural diagram of an ETC checkout security control system according to an embodiment of the invention. As shown in fig. 2, the ETC checkout security control system of the embodiment of the invention comprises an acquisition module (101), a processing module (102) and a storage module (103), wherein the processing module (102) is connected with the acquisition module (101) and the storage module (103); wherein the memory module (103) is adapted to store executable computer program code; the acquisition module (101) is used for acquiring driving data according to the control instruction of the processing module (102); the method is characterized in that: the processing module (102) is configured to execute the method according to embodiment one by invoking the executable computer program code in the storage module (103).
