All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

At present, after a traffic accident occurs on a highway, a traffic accident party generally calls a telephone for alarming, and in order to ensure the smoothness of a road, a traffic police can require the traffic accident party to move a vehicle to the side of the road or to go down to a highway junction, and wait for the traffic police to arrive at the scene for disposal. After the traffic police arrives at the scene, the traffic accident party is inquired, the road side monitoring record is called, and the like to judge the responsibility, so that a great amount of time is spent, inconvenience is brought to the traffic accident party, the workload of the traffic police is increased, and the condition that the traffic accident party is not satisfied with the judging result because no accident scene information is reserved is more likely to happen. In addition, some traffic accident parties can intentionally generate accidents, and the insurance is cheated, so that the economy is influenced.

Based on the method and the system for remotely disposing the expressway accident, provided by the embodiment of the invention, the accuracy and the efficiency of identifying the accident responsibility of the expressway can be improved, and the social and economic losses are reduced.

For the sake of understanding the present embodiment, first, a method for remote highway accident disposal disclosed in the present embodiment is described in detail, and referring to fig. 1, the method may include the following steps:

step S102, based on a matching relation between a preset expressway section and a traffic police command center, a video alarm request from a mobile terminal corresponding to an accident occurrence party is sent to a target traffic police command center corresponding to the accident occurrence section.

In an exemplary embodiment, a matching relationship table between each highway section and each traffic police command center may be established in advance on a middleware (such as a server) of a mobile terminal (such as a mobile phone) for an accident party, and when a traffic accident occurs on the highway, the accident party may send a video alarm request through the mobile terminal (such as the mobile phone) carried by itself, and may determine the traffic police command center to which the accident section belongs based on the matching relationship table and send the video alarm request to the traffic police command center for video alarm.

Step S104, after the target traffic police command center responds to the video alarm request, acquiring first video data acquired by the mobile terminal in the moving process, and acquiring evidence information of the accident occurrence road section according to the first video data and the police database.

The traffic police command center receiving the video alarm request establishes video communication with the mobile terminal after responding to the video alarm request, and the traffic police can remotely command the accident occurrence party to enable the mobile terminal to move to a proper position of the accident occurrence site in the video communication so as to ensure that video data collected by the mobile terminal contains as much effective information as possible (such as license plate number, vehicle position, vehicle collision position, driving license, face and the like), thereby enabling the video data obtained by the traffic police command center to contain as much effective information as possible; because the accident of the expressway is easy to cause secondary accidents, road congestion and the like, after the video data acquired by the traffic police command center contain as much effective information as possible, traffic police can also remotely guide an accident producer to evacuate from the scene in the video communication; the traffic police command center can identify the effective information contained in the video data through an image identification technology and call the police database to acquire related data (including vehicle detailed information, insurance information, driver information, driving license information, identity card information and the like), so that the effective information contained in the video data and the related data in the police database are combined to obtain evidence information of an accident road section.

And S106, the target traffic police command center acquires second video data acquired by the road side unit of the accident road section in the accident occurrence period, and acquires vehicle behavior information of the accident road section according to the evidence information and the second video data.

The accident occurrence period may be a period including an accident occurrence time. The vehicle behavior information can reflect the behavior of vehicle lane changing, rear-end collision and the like, and the specific content can be customized according to actual requirements without limitation.

Step S108, the target traffic police command center determines the accident type according to the vehicle behavior information, generates an original responsibility identification book according to the evidence information, the accident type, the preset responsibility identification book template and voice data input by the traffic police, and then sends the original responsibility identification book to the mobile terminal.

For example, for a traffic accident in which a vehicle collides, the vehicle behavior information includes a collision angle when the vehicle collides, the type of the accident can be determined according to the magnitude of the collision angle, and the type of the accident can include a rear-end collision, lane change, and the like, which is not limited.

The preset responsibility assignment book template is generated with reference to the responsibility assignment book of the current specification, and the original responsibility assignment book can be generated by filling contents related to evidence information, accident type, voice data input by the traffic police, and the like into the preset responsibility assignment book template.

Step S110, the target traffic police command center receives and stores the accident responsibility identification book with the accident party signature from the mobile terminal.

Wherein, the mobile terminal can be used for: receiving an original responsibility identification book; in response to a signature operation aiming at an original responsibility identification book, adding an accident generating party signature to the original responsibility identification book to obtain an accident responsibility identification book; and sending the accident responsibility identification book to the target traffic police command center.

After receiving the original responsibility identification book sent by the traffic police command center, the mobile terminal can sign the original responsibility identification book through the mobile terminal (for example, sign a name with a finger or a touch pen at a designated position on the original responsibility identification book), add an accident party signature to the designated position on the original responsibility identification book after responding to the signing operation, thereby obtaining an accident responsibility identification book with the accident party signature, and then send the accident responsibility identification book to the traffic police command center for storage, and finally complete the responsibility identification process.

According to the expressway accident remote disposal method provided by the embodiment of the invention, after a target traffic police command center corresponding to an accident road section responds to a video alarm request from a mobile terminal corresponding to an accident party, first video data acquired by the mobile terminal in a moving process are acquired, and evidence information of the accident road section is acquired according to the first video data and a police database; the target traffic police command center acquires second video data acquired by a road side unit of the accident road section in the accident occurrence period, and acquires vehicle behavior information of the accident road section according to the evidence information and the second video data; the target traffic police command center determines the accident type according to the vehicle behavior information, generates an original responsibility identification book according to the evidence information, the accident type, a preset responsibility identification book template and voice data input by traffic police, and then sends the original responsibility identification book to the mobile terminal; the target traffic police command center receives and stores the accident responsibility identification book with the accident party signature from the mobile terminal. By adopting the technology, when traffic accidents occur on the expressway, the traffic accident responsibility can be identified remotely by the target traffic police command center corresponding to the accident road section through the video data of the mobile terminal, the police database and the video data of the corresponding road side unit in a mode that the accident party corresponds to the mobile terminal for video alarming, so that the accuracy and efficiency of traffic accident responsibility identification are improved, and social and economic losses are reduced.

As a possible implementation manner, the step S102 (that is, based on the matching relationship between the preset expressway section and the traffic police command center, the step of sending the video alarm request from the mobile terminal corresponding to the accident occurrence party to the target traffic police command center corresponding to the accident occurrence section) may include:

(11) And responding to the video alarm request sent by the mobile terminal, acquiring the geographic position of the expressway where the mobile terminal is located, and determining an accident occurrence road section according to the geographic position.

(12) And determining a target traffic police command center based on the matching relation, and sending a video alarm request to the target traffic police command center.

As a possible implementation manner, the acquiring evidence information of the accident road section according to the first video data and the police database in the step S104 may include:

(21) Extracting on-site evidence of an accident road section from the first video data;

the on-site evidence includes, but is not limited to, a license plate number, and for example, the on-site evidence may include a position of a vehicle, a collision position of the vehicle, a driving license, a face, and the like, in addition to the license plate number.

For example, at least one frame of target image containing the live evidence target may be captured from the first video data, the live evidence target contained in each frame of target image may be identified, and all of the identified live evidence targets may be combined into the live evidence. For example, field information such as license plate number, driving license and the like in each frame of target image is identified as a scene evidence target through OCR image identification technology (a series of processes such as image input, image preprocessing, text detection, text recognition, text output and the like), and a face in each frame of target image is identified as a scene evidence target through face recognition technology (a series of processes such as image input, face detection, face tracking, face feature extraction and recognition and the like), and then all the identified scene evidence targets are subjected to duplication elimination and the scene evidence targets which remain after the duplication elimination form scene evidence of an accident occurrence road section.

(22) And acquiring police data related to the on-site evidence from the police database, and checking the on-site evidence by utilizing the police data.

The traffic police command center can find out target data corresponding to the license plate number from the police database after obtaining the field evidence of the accident road section, and extract the target data as police data; and then the traffic police command center compares the on-site evidence with the police data to judge the coincidence degree between the on-site evidence and the police data, namely, judges the authenticity of the on-site evidence by taking the police data as a reference basis so as to realize the verification of the on-site evidence.

(23) If the on-site evidence verification is passed, determining evidence information according to the on-site evidence and police data, and acquiring the evidence information.

When the on-site evidence verification passes, the traffic police command center judges that the on-site evidence is truly effective, correlates the on-site evidence with police data, removes the duplication, and then composes the information remained after the correlation and the duplication into evidence information of an accident road section.

As a possible implementation manner, the acquiring the vehicle behavior information of the accident-occurrence section according to the evidence information and the second video data in the step S106 may include: and identifying a vehicle target corresponding to the license plate number from the second video data through a pre-trained target detection model, tracking the vehicle target, and extracting the obtained moving track of the vehicle target as vehicle behavior information.

The object detection model may be YOLO (You Only Look Once), SSD (Single Shot MultiBox Detector), or the like, and is not limited thereto. Taking the object detection model as an example, YOLO V5 is adopted, accident occurrence video data (namely second video data) acquired by a drive test unit of an accident occurrence road section and license plate numbers in the evidence information can be input into the object detection model to identify and track a vehicle object, the input video data is normalized through the object detection model, image characteristics are extracted and transferred, a detection frame of the vehicle object is generated, the detection frame is tracked, and the like, so that a movement track of the vehicle object is obtained, and the movement track of the obtained vehicle object can be extracted as vehicle behavior information because the movement track of the vehicle object can reflect corresponding vehicle behaviors.

As a possible implementation manner, generating the original responsibility assignment book according to the evidence information, the accident type, the preset responsibility assignment book template, and the voice data input by the traffic police in the step S108 may include:

(31) Voice information related to accident liability is identified from the voice data by means of hidden markov models (Hidden Markov Model, HMM).

Illustratively, after the traffic police judges the accident responsibility party according to the regulations of the road safety law of the people's republic of China, voice data containing the relevant dictation of the accident responsibility is input to the traffic police command center through a voice input device connected with the traffic police command center, so that the traffic police command center recognizes the relevant dictation of the accident responsibility from the input voice data through the HMM as voice information related to the accident responsibility.

(32) Generating accident information according to the evidence information, the accident type and the voice information, and filling the accident information into a preset responsibility identification book template to obtain an original responsibility identification book.

Illustratively, after obtaining the evidence information, the accident type and the voice information, the traffic police command center may correlate the evidence information, the accident type and the voice information together to obtain accident information (including driver name, driver license information, driving license information, insurance information, responsibility identification result of the traffic police, etc.) and then populate the accident information into a preset responsibility identification book template to obtain an original responsibility identification book.

As a possible implementation manner, the police data can include insurance information; based on this, the highway accident remote handling method may further include: if the number of times of risk emergence in the insurance information exceeds a preset threshold value, generating early warning information representing the risk of cheating insurance.

The traffic police command center, after extracting corresponding police data containing insurance information from the police database by using license plate numbers, judges whether the number of times of danger in the insurance information exceeds a preset threshold, if so (that is, the number of times of danger in the insurance information exceeds the preset threshold), indicates that the traffic accident occurred by the vehicle with the license plate number has a cheating protection risk, and can trigger a deliberate accident early warning mechanism of the traffic police command center to generate corresponding early warning information to represent the cheating protection risk so as to facilitate timely processing of traffic police.

For ease of understanding, the above-described highway accident remote management method is exemplarily described herein below with a specific application as an example. Referring to fig. 2, the above-mentioned highway accident remote disposal method may be performed in the following operation manner:

step S202, after the traffic accident occurs on the expressway, matching the video alarm request to a traffic police command center corresponding to the accident road section, and establishing video call between the traffic police and the traffic accident party.

The specific operation manner of step S202 may include: after an accident party initiates a video request by using a handheld mobile device (i.e. a mobile terminal such as a mobile phone and the like), the geographic position of the road section where the accident party is located is obtained, a corresponding traffic police command center is matched for the geographic position by utilizing a preset matching relationship between the expressway road section and the traffic police command center, and then the video request is pushed to the traffic police command center, so that the video call between traffic police and the traffic accident party is established.

In step S204, the traffic police uses the camera device of the mobile device (such as the camera of the mobile phone) to perform mobile evidence collection by using the video to instruct the traffic accident party, intercepts the image, and guides the traffic accident party to withdraw from the scene after the image is intercepted.

The video call is applicable to a slight accident, and the specific operation manner of the step S204 may include: in the video call, the traffic police directs the accident party to hold the mobile equipment and move the camera device of the mobile equipment to a proper position, and then intercepts the image, thereby ensuring that the intercepted image contains site information. For example: in the video call, the traffic police swings the accident side mobile phone, obtains the scene picture containing license plate number, vehicle position, collision point, driving license and the like through the traffic police command center in the moving process, and collects the face of the accident side. Because the accident of the expressway is easy to cause secondary accident and road congestion, after the image is intercepted, traffic police guides accident party to withdraw from the scene in video call.

Step S206, extracting the presence information from the intercepted image by image recognition and voice recognition technology, and calling corresponding data in the police database to verify the presence information.

The specific operation manner of step S206 may include: the traffic police command center recognizes field information such as license plates, drivers' license plates, running license plates and the like from the intercepted images through an OCR image recognition technology, and the traffic police command center recognizes faces from the intercepted images through a face recognition technology; the traffic police command center uses the license plate number to match the corresponding police data (including vehicle detailed information, insurance information, driver information, travel license information, identity card information and the like) from the police database, and checks whether the field information (i.e. field information and face information) is consistent with the corresponding police data, if so, the corresponding police data is checked to pass, and if not (i.e. the field information is inconsistent with the corresponding police data), the corresponding police data is checked to fail.

In the step S206, after the traffic police command center matches the license plate number with the corresponding police data containing the insurance information from the police database, the license plate number can be used as a key to perform association comparison between the field information and the police data, thereby realizing verification of the field information.

In the step S206, after the traffic police command center matches the corresponding police data containing insurance information from the police database with the license plate number, if the number of times of accident side danger exceeds the preset threshold, the intentional accident early warning mechanism of the traffic police command center is triggered to perform early warning so as to prompt the traffic police that the traffic accident has a cheating protection risk.

Step S208, accident information is automatically generated and filled in the responsibility identification book, the responsibility identification book is sent to the traffic accident party for confirmation and signature, and the signed responsibility identification book returned by the traffic accident party is received and stored.

The specific operation manner of step S208 may include: the traffic police calls road side video data acquired by a road side unit of an accident road section through a traffic police command center, inputs a license plate number passing the verification and the road side video data into a pre-trained target detection model YOLO V5 to identify and track a vehicle target, then extracts a moving track (comprising a collision included angle) of the vehicle target output by the YOLO V5 as vehicle behavior information, and determines the accident type according to the size of the collision included angle in the vehicle behavior information; the traffic police judges accident responsibility parties according to the regulations of the road safety law of the people's republic of China and inputs voice data containing accident responsibility identification results to a traffic police command center through voice input equipment, and the traffic police command center identifies accident responsibility identification result information contained in the voice data through a Hidden Markov Model (HMM); the traffic police command center generates a responsibility identification book template, and associates the field information and the face information which pass the verification with the accident type and the corresponding police data to form accident information and fills the accident information in the responsibility identification book template; after the traffic police confirms the responsibility identification book obtained after filling the accident information, the traffic police command center sends the responsibility identification book after the traffic police confirms to the mobile equipment used by the traffic accident party, so that the traffic accident party confirms and signs the responsibility identification book on the mobile equipment and returns the signed responsibility identification book to the traffic police command center for storage.

In addition, the traffic police command center can also comprise a network unit, wherein the network unit consists of hardware equipment supporting multi-network cable access.
