Fig. 1 is a flowchart of an identity recognition method for a vehicle with an occluded license plate according to an embodiment of the present invention, where as shown in fig. 1, the identity recognition method for a vehicle with an occluded license plate includes:

and step 11, the background server acquires vehicle information of the vehicle with the shielded license plate, wherein the vehicle information comprises vehicle identification information of the vehicle with the shielded license plate, residual license plate number information of the vehicle with the shielded license plate and position information of the vehicle with the shielded license plate.

And step 12, the background server determines at least one complete license plate number according to the residual license plate number information, and the vehicle identification information of the vehicle corresponding to each complete vehicle number is the same as the vehicle identification information of the vehicle with the license plate covered.

And step 13, the background server acquires the vehicle owner communication numbers corresponding to the complete license plate numbers and acquires the position information corresponding to the vehicle owner communication numbers.

And step 14, the background server determines the vehicle owner communication number and the complete license plate number corresponding to the license plate sheltering vehicle according to the position information of the license plate sheltering vehicle and the position information corresponding to each vehicle owner communication number.

In the technical scheme of the identity recognition method for the license plate sheltered vehicle, the background server determines at least one complete license plate number, corresponding to the vehicle identification information of the vehicle, which is the same as the vehicle identification information of the license plate sheltered vehicle, according to the residual license plate number information of the license plate sheltered vehicle, acquires the vehicle owner communication numbers corresponding to the complete license plate numbers and the position information corresponding to the vehicle owner communication numbers, and determines the vehicle owner communication numbers and the complete license plate numbers corresponding to the license plate sheltered vehicle according to the position information of the license plate sheltered vehicle and the position information corresponding to the vehicle owner communication numbers, so that the identity of the license plate sheltered vehicle is effectively recognized, the license plate sheltered vehicle is recognized, and the labor cost and the time cost of a traffic police for recognizing the license plate sheltered vehicle can be.

Fig. 2 is a flowchart of an identity recognition method for a vehicle with a covered license plate according to a second embodiment of the present invention, and as shown in fig. 2, the method includes:

step 21, the first monitoring device obtains a first vehicle image of the vehicle and a first shooting time corresponding to the first vehicle image.

When the vehicle runs into the monitoring range of the first monitoring device on a road section, the first monitoring device obtains a first vehicle image of the vehicle and first shooting time corresponding to the first vehicle image. In this embodiment, the first monitoring device may be any monitoring device on the road segment. For example, the road segment may be a road segment for one-way driving, and the first monitoring device may be a monitoring device disposed at a start position of the road segment; for example, the road segment may also be a bidirectional travel road segment, and the first monitoring device may be a monitoring device disposed at a start position of each travel direction of the road segment.

And step 22, the first monitoring device acquires the vehicle identification information and the license plate number information of the vehicle according to the first vehicle image.

In the present embodiment, the vehicle identification information may include at least one of vehicle type information, vehicle color information, and vehicle sign information.

In this embodiment, the first monitoring device may recognize the vehicle identification information and the license plate number information of the vehicle from the first vehicle image of the vehicle through an image recognition technology.

In this embodiment, the license plate number information may include a license plate number image, or may include a license plate number identified by an image recognition technology.

And step 23, the first monitoring device judges whether the license plate of the vehicle is partially shielded according to the license plate number information, if so, the vehicle is determined as a shielded license plate vehicle and step 24 is executed, and if not, the flow is ended.

In this embodiment, if the first monitoring device determines that the license plate of the vehicle is not blocked, the process is ended; if the first monitoring device judges that the license plate of the vehicle is completely shielded, the process is ended; if the first monitoring device determines that the license plate of the vehicle is partially shielded, the first monitoring device determines that the vehicle is a shielded license plate vehicle and executes step 24.

Taking the license plate of a general vehicle in the chinese region as an example, the characters of the license plate number of the general vehicle include chinese characters, english letters, and numbers, such as kyo a.f 1234. As an example, when the number of characters of the recognized license plate number is less than the total number of characters of the complete license plate number (e.g., the total number of characters of the complete license plate number is 7), it indicates that the license plate of the vehicle is partially occluded; when the number of the characters of the license plate number of the vehicle is recognized to be complete, the license plate of the vehicle is indicated to be not shielded; when the license plate number cannot be identified, the license plate is completely shielded.

Optionally, the first monitoring device sends warning information to the traffic control command center according to the license plate number information if the license plate of the vehicle is judged to be completely shielded, so as to prompt a traffic police department that the vehicle with the shielded license plate passes through the road section where the first monitoring device is located, thereby improving the efficiency of the traffic police department in handling the violation behavior of shielding the license plate. Then, the flow ends.

Optionally, in step 23, the first monitoring device further determines, according to the license plate number information, whether the number of characters of the portion of the vehicle where the license plate is blocked is less than or equal to a preset number threshold when it is determined that the license plate of the vehicle is partially blocked, if so, determines that the vehicle is a vehicle where the license plate is blocked and executes step 24, otherwise, ends the procedure.

The preset number threshold may be 2, and may also be set according to an actual situation.

Optionally, if the first monitoring device further determines that the number of characters of the portion of the vehicle where the license plate is blocked exceeds a preset number threshold (e.g. 2), sending an alarm message to a traffic control command center to prompt a traffic police department that the vehicle with the blocked license plate passes through the road segment where the first monitoring device is located, so as to improve the efficiency of the traffic police department in handling the violation behavior of blocking the license plate, and then ending the process.

It is understood that a blocked license plate vehicle refers to a vehicle that has a violation that blocks the license plate number.

And step 24, the first monitoring device acquires the residual license plate number information of the shielded license plate vehicle according to the license plate number information and acquires the first position coordinate of the shielded license plate vehicle at the first shooting time.

In this embodiment, in the license plate number information, the characters of the shielded portion may be replaced by preset characters (such as X), such as jing a.f1xx4; the residual license plate number information may include characters of an unobstructed portion of the recognized license plate number and characters for replacing the obstructed portion of the characters, such as jing a. f1 xx4.

Optionally, in order to identify the identity of the license plate obstructing vehicle in time, the first monitoring device may acquire the residual license plate number information of the license plate obstructing vehicle only for the license plate obstructing vehicle whose number of characters is 1 or 2.

In this embodiment, the first position coordinate of the vehicle with the license plate covered at the first shooting time may be the position coordinate of the first monitoring device. Optionally, the first position coordinate of the vehicle with the license plate covered at the first shooting time may also be calculated by the first monitoring device according to the position coordinate of the first monitoring device and the monitoring view angle range of the first monitoring device. The first monitoring device can perform GPS positioning through a positioning device arranged on the first monitoring device so as to obtain the position coordinates of the first monitoring device; when the first monitoring apparatus is installed, the position coordinates of the installation position may be obtained in advance and stored in the first monitoring apparatus as the position coordinates of the first monitoring apparatus.

And step 25, the first monitoring device sends vehicle information of the shielded license plate vehicle to the background server, wherein the vehicle information comprises vehicle identification information, residual license plate number information and position information of the shielded license plate vehicle, and the position information of the shielded license plate vehicle comprises a first position coordinate of the shielded license plate vehicle at a first shooting time.

And step 26, the background server determines at least one complete license plate number according to the residual license plate number information, wherein the vehicle identification information of the vehicle corresponding to each complete vehicle number is the same as the vehicle identification information of the vehicle with the license plate covered.

In this embodiment, step 26 includes:

and 261, determining the complete license plate numbers of all possible vehicles with the shielded license plate according to the residual license plate number information by the background server.

In this embodiment, the background server first calculates all possible complete license plate numbers according to the information of the residual license plate numbers. If the residual license plate number information is jing a.f1xx4, where "XX" is a character of the occluded part, all possibilities of "XX" need to be calculated, and if "XX" is determined as "00", "01", "02", "03", … …, and so on, all possible complete license plate numbers can be obtained.

And step 262, the background server sends a query request to the vehicle information database to request to query all possible complete license plate numbers, wherein the corresponding vehicle identification information of the vehicle is the same as the complete license plate number of the vehicle with the license plate shielded.

Specifically, after all possible complete license plate numbers are determined, the background server initiates query to the vehicle information database so as to query at least one complete license plate number, of all possible complete license plate numbers, of which the corresponding vehicle identification information is the same as the vehicle identification information of the vehicle with the license plate covered.

The vehicle information database maintains registration information of all vehicles on the road, wherein the registration information at least comprises vehicle identification information, a complete license plate number, vehicle owner information and vehicle owner communication numbers of the vehicles. For example, the vehicle owner communication number is a vehicle owner mobile phone number, and the vehicle owner information may include vehicle owner identification card information, driving license information, driver license information, address information, and the like.

And 263, the background server receives a query result returned by the vehicle information database, wherein the query result comprises at least one complete license plate number, and the vehicle identification information of the vehicle corresponding to each complete vehicle number is the same as the vehicle identification information of the vehicle with the license plate covered.

And 27, the background server acquires the vehicle owner communication numbers corresponding to the complete license plate numbers and acquires the position information corresponding to the vehicle owner communication numbers.

Specifically, in step 27, the background server may initiate an inquiry to the vehicle information database to inquire the car owner communication number corresponding to each complete license plate number, for example, the car owner communication number is a car owner mobile phone number; after acquiring the vehicle owner communication numbers corresponding to the complete license plate numbers, the background server can initiate position query of the vehicle owner communication numbers to the cloud communication platform server so as to acquire position information corresponding to the vehicle owner communication numbers, wherein the position information corresponding to the vehicle owner communication numbers comprises second position coordinates corresponding to the vehicle owner communication numbers at the first shooting time.

Optionally, in the step 263, the query result may also include the car owner communication number corresponding to each complete license plate number. In this case, in step 27, the background server does not need to acquire the car owner communication numbers corresponding to the complete license plate numbers, that is, in step 27, the background server only executes the step of acquiring the position information corresponding to the car owner communication numbers.

And step 28, the background server determines the vehicle owner communication number and the complete license plate number corresponding to the vehicle with the license plate shielded according to the position information of the vehicle with the license plate shielded and the position information corresponding to each vehicle owner communication number.

In this embodiment, according to the descriptions in step 25 and step 27, the position information of the blocked license plate vehicle includes a first position coordinate of the blocked license plate vehicle at the first shooting time, and the position information corresponding to the car owner communication number includes a second position coordinate of the blocked license plate vehicle at the first shooting time. Specifically, step 28 includes:

step 281, the background server judges whether a distance between a second position coordinate of the vehicle owner communication number at the first shooting time and a first position coordinate of the vehicle with the license plate covered at the first shooting time is smaller than or equal to a preset distance threshold value or not according to each vehicle owner communication number, if yes, step 282 is executed, and if not, the vehicle owner communication number is not further processed.

The preset distance threshold may be set according to actual needs, for example, the preset distance threshold may be 0.5 meter, 1 meter, or 2 meters, and the like. In step 281, when the background server determines that the distance between the second position coordinate at the first shooting time corresponding to the car owner communication number and the first position coordinate at the first shooting time of the blocking license plate vehicle is less than or equal to the preset distance threshold, it indicates that the car owner communication number and the blocking license plate vehicle are in the same or similar positions at the first shooting time, and the complete license plate number and the vehicle identification information corresponding to the car owner communication number both correspond to the blocking license plate vehicle, so that the car owner communication number is most likely to be the car owner communication number of the car owner of the blocking license plate vehicle, and the complete license plate number corresponding to the car owner communication number is most likely to be the complete license plate number of the blocking license plate vehicle, and therefore, step 282 is executed.

In this embodiment, when the distance between the second position coordinate at the first shooting time corresponding to each car owner communication number and the first position coordinate at the first shooting time of the license plate sheltered vehicle is greater than the preset distance threshold, only sending the warning information to the traffic control command center to prompt the traffic police department that the vehicle sheltered from the license plate passes through the road section where the first monitoring device is located, so as to improve the efficiency of the traffic police department in handling the violation behavior of sheltering from the license plate, and then ending the flow.

And 282, the background server determines the vehicle owner communication number and the complete license plate number corresponding to the vehicle owner communication number as the vehicle owner communication number and the complete license plate number corresponding to the shielded license plate vehicle.

In this embodiment, the number of the finally determined vehicle-owner communication numbers corresponding to the license plate-obstructing vehicles is one, that is, the number of the complete license plate numbers corresponding to the license plate-obstructing vehicles is one.

In this embodiment, if it is determined that there are a plurality of car owner communication numbers corresponding to the license plate sheltered vehicles, that is, the number of complete license plate numbers corresponding to the license plate sheltered vehicles is multiple, the vehicle information of the license plate sheltered vehicles fed back by other monitoring devices may be further determined (the specific flow of the vehicle information of the license plate sheltered vehicles fed back by other monitoring devices may refer to the above-mentioned step 21 to step 25), whether a distance between the position information of the license plate sheltered vehicles fed back by other monitoring devices and the position information of each car owner communication number in the plurality of car owner communication numbers is smaller than or equal to a preset distance threshold value is determined (refer to step 281), and if there is a car owner communication number satisfying a condition in the plurality of car owner communication numbers corresponding to the license plate sheltered vehicles, the car owner communication number is determined as the car owner communication number corresponding to the license plate sheltered vehicles, and the complete license plate number corresponding to the car owner communication number is determined as the complete license plate number And (4) repeating the steps until a vehicle owner communication number and a complete license plate number corresponding to the vehicle with the shielded license plate are finally determined.

And step 29, the background server sends vehicle violation information to the traffic control command center, wherein the vehicle violation information comprises a complete license plate number of a vehicle with a shielded license plate.

In the technical scheme of the identification method for the vehicle with the license plate covered, provided by the embodiment, the first monitoring device monitors the vehicle with the license plate covered, the background server acquires the vehicle information of the vehicle with the license plate covered from the first monitoring device, determining at least one complete license plate number of the corresponding vehicle, the vehicle identification information of which is the same as that of the vehicle with the shielded license plate, according to the residual license plate number information of the vehicle with the shielded license plate, and acquires the car owner communication number corresponding to each complete license plate number and the position information corresponding to each car owner communication number, according to the position information of the vehicle with the blocked license plate and the position information corresponding to each vehicle-owner communication number, the vehicle-owner communication number and the complete license plate number corresponding to the vehicle with the blocked license plate are determined, therefore, the identity of the vehicle with the shielded license plate can be effectively identified, the vehicle with the shielded license plate can be identified, and the labor cost and the time cost for the traffic police department to identify the vehicle with the shielded license plate can be effectively saved.

Fig. 3 is a flowchart of an identity recognition method for a vehicle with a covered license plate according to a third embodiment of the present invention, and as shown in fig. 3, the method includes:

As an example, when the number of characters of the recognized license plate number is less than the total number of characters of the complete license plate number (e.g., the total number of characters of the complete license plate number is 7), it indicates that the license plate of the vehicle is partially occluded; when the number of the characters of the license plate number of the vehicle is recognized to be complete, the license plate of the vehicle is indicated to be not shielded; when the license plate number cannot be identified, the license plate is completely shielded.

Optionally, the background server sends warning information to the traffic control command center according to the license plate number information if the license plate of the vehicle is judged to be completely shielded, so as to prompt the traffic police department that the vehicle with the shielded license plate passes through the road section where the first monitoring device is located, thereby improving the efficiency of the traffic police department in handling the violation behavior of shielding the license plate, and then ending the flow.

Optionally, in step 33, the background server further determines, according to the license plate number information, whether the number of characters of the portion of the vehicle where the license plate is blocked is less than or equal to a preset number threshold when it is determined that the license plate of the vehicle is partially blocked, if so, execute step 34, otherwise, end the process.

And step 34, the background server determines the vehicle as an occlusion license plate vehicle, and acquires the residual license plate number information of the occlusion license plate vehicle according to the license plate number information.

And step 35, the background server generates vehicle information of the shielded license plate vehicle according to the vehicle identification information, the residual license plate number information and the first position coordinate of the shielded license plate vehicle, wherein the vehicle information comprises the vehicle identification information, the residual license plate number information and the position information of the shielded license plate vehicle, and the position information of the shielded license plate vehicle comprises the first position coordinate of the shielded license plate vehicle at the first shooting time.

And step 36, the background server determines at least one complete license plate number according to the residual license plate number information, and the vehicle identification information of the vehicle corresponding to each complete vehicle number is the same as the vehicle identification information of the vehicle with the license plate covered.

And step 37, the background server acquires the vehicle owner communication numbers corresponding to the complete license plate numbers and acquires the position information corresponding to the vehicle owner communication numbers.

The position information corresponding to the car owner communication number comprises a second position coordinate corresponding to the car owner communication number in the first shooting time. For a detailed description of step 37, reference is made to the above description of step 27, which is not repeated herein.

And step 38, the background server determines the vehicle owner communication number and the complete license plate number corresponding to the shielded license plate vehicle according to the position information of the shielded license plate vehicle and the position information corresponding to each vehicle owner communication number.

Specifically, step 38 includes:

step 381, the background server judges whether the distance between the second position coordinate of the vehicle owner communication number at the first shooting time and the first position coordinate of the vehicle with the license plate covered at the first shooting time is smaller than or equal to a preset distance threshold value or not according to each vehicle owner communication number, if yes, step 382 is executed, and if not, the vehicle owner communication number is not further processed.

For a detailed description of this step 381, refer to the description of step 281 described above, which is not repeated herein.

Step 382, the background server determines the vehicle owner communication number and the complete license plate number corresponding to the vehicle owner communication number as a vehicle owner communication number and a complete license plate number corresponding to the shielded license plate vehicle.

In this embodiment, if it is determined that there are a plurality of owner communication numbers corresponding to the license plate-blocked vehicle, that is, a plurality of complete license plate numbers corresponding to the license plate-blocked vehicle, the monitoring information of the license plate-blocked vehicle fed back by other monitoring devices may be further used to obtain the vehicle information of the license plate-blocked vehicle (the specific process of obtaining the vehicle information of the license plate-blocked vehicle may refer to the above steps 31 to 35), it is determined whether the distance between the position information of the license plate-blocked vehicle fed back by other monitoring devices and the position information of each of the plurality of owner communication numbers is less than or equal to a preset distance threshold (refer to step 381), and if there is an owner communication number satisfying a condition in the plurality of owner communication numbers corresponding to the license plate-blocked vehicle, the owner communication number is determined as the owner communication number corresponding to the license plate-blocked vehicle, and determining the finished license plate number corresponding to the vehicle owner communication number as the complete license plate number corresponding to the shielded license plate vehicle, and so on until finally determining a vehicle owner communication number and a complete license plate number corresponding to the shielded license plate vehicle.

For other details regarding this step 38, reference may be made to the above description of step 28, which is not repeated herein.

And step 39, the background server sends vehicle violation information to the traffic control command center, wherein the vehicle violation information comprises a complete license plate number of a vehicle with a shielded license plate.

The present embodiment is different from the second embodiment in that: in the second embodiment, the first monitoring device monitors and judges the vehicle with the license plate shielded, and the background server directly obtains the vehicle information of the vehicle with the license plate shielded from the first monitoring device.

In the technical scheme of the identification method for the vehicle with the covered license plate provided by the embodiment, the background server acquires first monitoring information from the first monitoring device, obtaining the vehicle information of the vehicle with the shielded license plate according to the first monitoring information, determining at least one complete license plate number of the vehicle with the same vehicle identification information of the vehicle with the shielded license plate according to the residual license plate number information of the vehicle with the shielded license plate, and acquires the car owner communication number corresponding to each complete license plate number and the position information corresponding to each car owner communication number, according to the position information of the vehicle with the blocked license plate and the position information corresponding to each vehicle-owner communication number, the vehicle-owner communication number and the complete license plate number corresponding to the vehicle with the blocked license plate are determined, therefore, the identity of the vehicle with the shielded license plate can be effectively identified, the vehicle with the shielded license plate can be identified, and the labor cost and the time cost for the traffic police department to identify the vehicle with the shielded license plate can be effectively saved.

Fig. 4 is a flowchart of an identity recognition method for a vehicle with a covered license plate according to a fourth embodiment of the present invention, as shown in fig. 4, the method includes:

step 41, the first monitoring device obtains a first vehicle image of the first vehicle and corresponding first shooting time.

For the detailed description of step 41, reference may be made to the description of step 21 in the second embodiment, and details are not repeated here.

And 42, the first monitoring device acquires the vehicle identification information and the license plate number information of the first vehicle according to the first vehicle image.

For a detailed description of step 42, reference may be made to the description of step 22 in the second embodiment, and details are not repeated here.

And 43, judging whether the license plate of the first vehicle is partially shielded or not by the first monitoring device according to the license plate number information of the first vehicle, if so, determining the first vehicle as the first shielded license plate vehicle and executing the step 44, otherwise, not performing further processing.

For the detailed description of step 43, reference may be made to the description of step 23 in the second embodiment, and details are not repeated here.

And step 44, the first monitoring device acquires the residual license plate number information of the first vehicle according to the license plate number information of the first vehicle, and acquires the first position coordinate of the first vehicle at the first shooting time.

In this embodiment, the first position coordinates of the first vehicle at the first photographing time may be position coordinates of the first monitoring device. Optionally, the first position coordinate of the first vehicle at the first shooting time may also be calculated by the first monitoring device according to the own position coordinate and the own monitoring view angle range.

For other specific descriptions of step 44, reference may be made to the description of step 24 in the second embodiment, and details are not repeated here.

And step 45, the first monitoring device sends the blocking license plate information of the first vehicle to the background server, wherein the blocking license plate information of the first vehicle comprises the vehicle identification information, the residual license plate number information and the first position coordinate of the first vehicle at first monitoring time, and the first monitoring time is first shooting time.

And step 46, aiming at each second monitoring device in at least one second monitoring device on the same road section as the first monitoring device, acquiring a second vehicle image of the second vehicle and a second shooting time corresponding to the second vehicle image by the second monitoring device.

When a second vehicle runs into the monitoring range of the second monitoring device on the road section where the first monitoring device is located, the second monitoring device obtains a second vehicle image of the second vehicle and second shooting time corresponding to the second vehicle image. The second monitoring device is other monitoring devices except the first monitoring device on the road section, and the first monitoring device and the at least one second monitoring device are arranged on the road section at intervals.

And step 47, the second monitoring device acquires the vehicle identification information and the license plate number information of the second vehicle according to the second vehicle image.

In the present embodiment, the vehicle identification information of the second vehicle may include at least one of vehicle type information, vehicle color information, and vehicle sign information.

In this embodiment, the second monitoring device may recognize the vehicle identification information and the license plate number information of the second vehicle from the second vehicle image of the second vehicle through an image recognition technology.

In this embodiment, the license plate number information of the second vehicle may include a license plate number image, or may include a license plate number identified by an image recognition technology.

And 48, judging whether the license plate of the second vehicle is partially shielded or not by the second monitoring device according to the license plate number information of the second vehicle, if so, determining the second vehicle as the second shielded license plate vehicle and executing the step 49, otherwise, not performing further processing.

In this embodiment, if the second monitoring device determines that the license plate of the second vehicle is not blocked, no further processing is performed; if the second monitoring device judges that the license plate of the second vehicle is completely shielded, no further processing is carried out; if the second monitoring device determines that the license plate of the second vehicle is partially blocked, the second monitoring device determines the second vehicle as a second blocked license plate vehicle and performs step 49.

Taking the license plate of a general vehicle in the chinese region as an example, the characters of the license plate number of the general vehicle include chinese characters, english letters, and numbers, such as kyo a.f 1234. As an example, when it is recognized that the number of characters of the license plate number of the second vehicle is less than the total number of characters of the complete license plate number (for example, the total number of characters of the complete license plate number is 7), it indicates that the license plate of the second vehicle is partially occluded; when the number of the characters of the license plate number of the second vehicle is recognized to be complete, the license plate of the second vehicle is indicated to be not shielded; and when the license plate number of the second vehicle cannot be identified, the license plate number of the second vehicle is completely shielded.

Optionally, the second monitoring device sends an alarm message to the traffic control command center according to the license plate number information if the license plate of the second vehicle is judged to be completely shielded, so as to prompt the traffic police department that the vehicle with the shielded license plate passes through the road section where the second monitoring device is located, thereby improving the efficiency of the traffic police department in handling the violation behavior of shielding the license plate. Then, the flow ends.

Optionally, in step 48, the second monitoring device further determines, according to the license plate number information, whether the number of characters of the portion of the second vehicle where the license plate is blocked is less than or equal to a preset number threshold when determining that the license plate of the second vehicle is partially blocked, if so, determines that the second vehicle is a second blocked license plate vehicle and performs step 49, otherwise, does not perform further processing.

Optionally, if the second monitoring device further determines that the number of characters of the portion, where the license plate of the second vehicle is blocked, exceeds a preset number threshold (e.g., 2), sending an alarm message to a traffic control command center to prompt a traffic police department that a vehicle, where the license plate of the second monitoring device is blocked, passes through the road section where the second monitoring device is located, so that the efficiency of the traffic police department in handling the violation behavior of blocking the license plate is improved, and then ending the flow.

It is understood that the second masked license plate vehicle is a vehicle having a violation that masks the license plate number.

And step 49, the second monitoring device acquires the residual license plate number information of the second vehicle according to the license plate number information of the second vehicle and acquires a third position coordinate of the second vehicle at the second shooting time.

Optionally, in order to be able to recognize the identity of the vehicle with the license plate covered in time, the second monitoring device may acquire the residual license plate number information of the second vehicle only for the second vehicle with the number of characters of the covered part of the license plate being 1 or 2.

In this embodiment, the third position coordinates of the second vehicle at the second photographing time may be position coordinates of the second monitoring device. Optionally, the third position coordinate of the second vehicle at the second shooting time may also be calculated by the second monitoring device according to the own position coordinate and the own monitoring view angle range. The second monitoring device can perform GPS positioning through a positioning device arranged on the second monitoring device so as to obtain the position coordinates of the second monitoring device; when the second monitoring apparatus is mounted, the position coordinates of the mounting position may be obtained in advance and stored in the second monitoring apparatus as the position coordinates of the second monitoring apparatus.

And step 50, the second monitoring device sends the shielded license plate information of the second vehicle to the background server, wherein the shielded license plate information of the second vehicle comprises the vehicle identification information and the residual license plate number information of the second vehicle and the third position coordinate of the second vehicle at the second monitoring time, and the second monitoring time is the second shooting time.

If the number of the second monitoring devices is multiple, when the second monitoring devices monitor that the license plate of the second vehicle is partially shielded in the respective monitoring ranges, the background server receives the license plate shielding information of the second vehicle sent by the second monitoring devices, wherein each second monitoring device judges whether the license plate of the second vehicle in the respective monitoring range is partially shielded through the steps 46 to 48. It should be noted that the second vehicles respectively monitored by the plurality of second monitoring devices may be the same vehicle or different vehicles, and the specific need is determined according to actual conditions.

Step 51, aiming at each second monitoring device, the background server compares the vehicle identification information of the first vehicle with the vehicle identification information of the second vehicle corresponding to the second monitoring device, compares the residual license plate number information of the first vehicle with the residual license plate number information of the second vehicle corresponding to the second monitoring device, if the comparison results are consistent, the step 52 is executed, otherwise, no further processing is carried out.

In this embodiment, if the background server only receives the blocking license plate information of the second vehicle sent by one second monitoring device, in step 51, the background server compares the vehicle identification information of the first vehicle with the vehicle identification information of the second vehicle corresponding to the second monitoring device, and compares the residual license plate number information of the first vehicle with the residual license plate number information of the second vehicle corresponding to the second monitoring device, if the comparison results are consistent, step 52 is executed, otherwise, no further processing is performed.

If the number of the second monitoring devices is multiple, and the background server receives the blocking license plate information of the second vehicles sent by the multiple second monitoring devices, in step 51, for the blocking license plate information of the second vehicle corresponding to each second monitoring device, the background server compares the vehicle identification information of the first vehicle corresponding to the first monitoring device with the vehicle identification information of the second vehicle corresponding to the second monitoring device, and compares the residual license plate number information of the first vehicle corresponding to the first monitoring device with the residual license plate number information of the second vehicle corresponding to the second monitoring device, and if the comparison results are consistent, step 52 is executed. Therefore, whether a first shielded license plate vehicle (first vehicle) monitored by the first monitoring device and a second shielded license plate vehicle (second vehicle) monitored by the plurality of second monitoring devices are the same shielded license plate vehicle can be determined.

And step 52, the background server determines the first vehicle and a second vehicle corresponding to the second monitoring device as the same vehicle with the same license plate covered.

It can be understood that the first vehicle is a first license plate obstructing vehicle, and the second vehicle corresponding to the second monitoring device is a second license plate obstructing vehicle.

In this embodiment, for the shielding license plate information of the second vehicle corresponding to each second monitoring device, when the background server determines that the vehicle identification information of the first vehicle is the same as the vehicle identification information of the second vehicle corresponding to the second monitoring device, and determines that the residual license plate number information of the first vehicle is the same as the residual license plate number information of the second vehicle corresponding to the second monitoring device, the background server determines that the second vehicle (the second shielding license plate vehicle) corresponding to the second monitoring device and the first vehicle (the first shielding license plate vehicle) corresponding to the first monitoring device are the same shielding license plate vehicle. Therefore, the same shielded license plate vehicle monitored by a plurality of monitoring devices (the first monitoring device and the second monitoring device) on the same road section can be determined.

And step 53, the background server determines the position information of the vehicle with the license plate covered according to the first position coordinate of the vehicle with the license plate covered at the first monitoring time and the third position coordinate of the vehicle with the license plate covered at the second monitoring time.

The position information of the license plate sheltering vehicle comprises position information of the license plate sheltering vehicle in a running time range, and the running time range is a time range generated according to the first monitoring time and the second monitoring time.

In this embodiment, if the backend server determines in step 51 and step 52 that the first vehicle (first occluded license plate vehicle) corresponding to the first monitoring device is only the same occluded license plate vehicle as the second vehicle (second occluded license plate vehicle) corresponding to the second monitoring device, in step 53, the backend server determines the position information of the occluded license plate vehicle according to the first position coordinate of the occluded license plate vehicle at the first monitoring time and the third position coordinate of the occluded license plate vehicle at the second monitoring time. In this case, the travel time range is a time range from a first monitoring time (first photographing time) corresponding to the first monitoring device to a second monitoring time (second photographing time) corresponding to the second monitoring device.

In this embodiment, the second monitoring time corresponding to each second monitoring device is different, and the third position coordinate corresponding to each second monitoring device is also different. Therefore, it can be understood that, if the background server determines in the

above steps

51 and 52 that the first vehicle (first occluded license plate vehicle) corresponding to the first monitoring device and the second vehicles (second occluded license plate vehicles) corresponding to the plurality of second monitoring devices are the same occluded license plate vehicle, in step 53, the background server determines the position information of the occluded license plate vehicle according to the first position coordinate of the occluded license plate vehicle at the first monitoring time and the third position coordinate of the occluded license plate vehicle at each second monitoring time. In this case, the travel time range is a time range from the first monitoring time to the maximum second monitoring time among the second monitoring times.

And step 54, the background server generates the vehicle information of the shielded license plate vehicle according to the vehicle identification information, the residual license plate number information and the position information of the shielded license plate vehicle.

The vehicle information comprises vehicle identification information, residual license plate number information and position information of the shielded license plate vehicle, the position information of the shielded license plate vehicle comprises the position information of the shielded license plate vehicle in a running time range, and the running time range is a time range generated according to the first monitoring time and the second monitoring time.

And step 55, the background server determines at least one complete license plate number according to the residual license plate number information of the vehicle with the shielded license plate, wherein the vehicle identification information of the vehicle corresponding to each complete vehicle number is the same as the vehicle identification information of the vehicle with the shielded license plate.

For a detailed description of this step 55, reference may be made to the description of step 26 in the above second embodiment, and details are not described here.

And step 56, the background server acquires the vehicle owner communication numbers corresponding to the complete license plate numbers and acquires the position information corresponding to the vehicle owner communication numbers.

The position information corresponding to the vehicle owner communication number comprises position information corresponding to the vehicle owner communication number within a driving time range.

For other descriptions of step 56, reference may be made to the description of step 27 in the above second embodiment, and further description is omitted here.

And 57, the background server determines the vehicle owner communication number and the complete license plate number corresponding to the shielded license plate vehicle according to the position information of the shielded license plate vehicle and the position information corresponding to each vehicle owner communication number.

In this embodiment, according to the descriptions of step 53 and step 56, the position information of the obstructing license plate vehicle includes the position information of the obstructing license plate vehicle in the driving time range, and the position information corresponding to the car owner communication number includes the position information corresponding to the car owner communication number in the driving time range.

Optionally, the position information of the license plate obstructing vehicle in the running time range includes a first position coordinate of the license plate obstructing vehicle in a first monitoring time (a first shooting time) and a third position coordinate of the license plate obstructing vehicle in a second monitoring time (a second shooting time), and the position information of the vehicle owner communication number in the running time range includes a second position coordinate of the vehicle owner communication number in the first monitoring time (the first shooting time) and a fourth position coordinate of the vehicle owner communication number in the second monitoring time (the second shooting time). In this case, step 57 comprises:

step 571a, aiming at each vehicle owner communication number, the background server judges whether the distance between the second position coordinate of the vehicle owner communication number at the first monitoring time and the first position coordinate of the vehicle with the license plate shielded at the first monitoring time is smaller than or equal to a preset distance threshold, if yes, step 572a is executed, otherwise, the vehicle owner communication number is not further processed.

For a detailed description of step 571a, reference may be made to the description of step 281 in the second embodiment, and details are not repeated here.

In step 572a, the background server further determines whether a distance between a fourth position coordinate of the vehicle owner communication number at the second monitoring time and a third position coordinate of the shielded license plate vehicle at the second monitoring time is smaller than or equal to a preset distance threshold, if so, executes step 573a, otherwise, does not further process the vehicle owner communication number.

The preset distance threshold may be set according to actual needs, for example, the preset distance threshold may be 0.5 meter, 1 meter, or 2 meters, and the like. In step 572a, when the backend server determines that the distance between the second position coordinate at the first monitoring time corresponding to the car owner communication number and the first position coordinate at the first monitoring time of the license plate-obstructing vehicle is less than or equal to the preset distance threshold, and determines that the distance between the fourth position coordinate at the second monitoring time corresponding to the car owner communication number and the third position coordinate at the second monitoring time of the license plate-obstructing vehicle is less than or equal to the preset distance threshold, it indicates that the car owner communication number and the license plate-obstructing vehicle are simultaneously present at the same or similar position at the first monitoring time, and are simultaneously present at the same or similar position at the second monitoring time, and the complete license plate number and the vehicle identification information corresponding to the car owner communication number are both consistent with the license plate-obstructing vehicle, so that the car owner communication number is most likely to be the car owner communication number of the license plate-obstructing vehicle, the complete license plate number corresponding to the vehicle owner communication number is most likely to be the complete license plate number of the vehicle with the hidden license plate, so step 573a is executed.

Step 573a, the background server determines the vehicle owner communication number and the complete license plate number corresponding to the vehicle owner communication number as the vehicle owner communication number and the complete license plate number corresponding to the shielded license plate vehicle.

For a detailed description of step 573a, reference may be made to the description of step 282 in the above second embodiment, and details are not repeated here.

Optionally, the position information of the vehicle covering the license plate within the driving time range includes a driving path of the vehicle covering the license plate within the driving time range, and the position information of the vehicle owner communication number within the driving time range includes a moving path of the vehicle owner communication number within the driving time range. In this case, step 57 comprises:

step 571b, the background server judges whether the matching degree between the moving path corresponding to each vehicle owner communication number within the driving time range and the driving path corresponding to the vehicle owner communication number within the driving time range is larger than or equal to a preset matching threshold value or not according to each vehicle owner communication number, if yes, step 572b is executed, and if not, the vehicle owner communication number is not further processed.

The preset matching threshold may be set according to actual needs, for example, the preset matching threshold is 90%. In the present embodiment, the matching degree between the travel path and the movement path may be a similarity between the travel path and the movement path.
