Detailed Description
To make the principles, technical solutions and advantages of the present application clearer, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Residential communities generally manage the parking spaces in a parking lot through a parking space management device. Generally, the parking space management device identifies the license plate number of the vehicle parked in the parking space, compares the license plate number with the license plate number bound to the parking space, and displays warning information if the license plate number is different from the license plate number bound to the parking space.
However, in the image recognition process, due to light, angle, broken license plate, ground reflection, etc., the numbers and/or letters with similar shapes are often recognized incorrectly, such as: 8. b and 3, 0, D, U and C, 1, L and 7, X, Y and V, etc. Therefore, even if the vehicle of the user belonging to the parking space is parked in the parking space, if the license plate number of the vehicle is identified wrongly, the parking space management device will identify the vehicle of the user parked in the parking space as a non-user vehicle and generate a wrong alarm, which may cause poor experience of the user belonging to the parking space.
The embodiment of the application provides a parking space management method, and in the method, a parking space not only binds a license plate number of an affiliated user, but also binds an alternative license plate number of the parking space. Therefore, the method can allow the license plate number recognition result to have a certain difference degree with the license plate number of the user to which the parking space belongs, so that the error alarm of the parking space management equipment is avoided, and the parking experience of the user is improved.
Fig. 1 is a flowchart of a parking space management method according to an embodiment of the present application, where the method may be used for a parking space management device in a parking space management system. As shown in fig. 1, the method includes:
The target parking space is any parking space of the parking lot of the community. The target vehicle is any vehicle parked in the target parking space, and the target vehicle may be a vehicle of a user in the target parking space or may not be a vehicle of a user in the target parking space.
Optionally, the parking space management device may collect a license plate image of a target vehicle parked in the target parking space, and recognize the target license plate number from the license plate image.
Illustratively, the parking space management system further comprises a camera arranged near the target parking space, and the parking space management device is connected with the camera. In step 101, the parking space management device may control the camera to capture the license plate image. For example, the parking space management device may control the camera to acquire a video stream of the target parking space, and then the parking space management device acquires the license plate image from the video stream. And then, the parking space management equipment can identify the target license plate number according to the license plate image. For example, the parking space management device may identify a target license plate number of a parked target vehicle through an artificial intelligence algorithm. Optionally, the target license plate number may also be sent to the parking space management device by the camera after the target license plate number is identified, which is not limited in the embodiment of the present application.
The target license plate number can be a license plate number which is correctly identified by the parking space management equipment, and can also be a license plate number which is incorrectly identified by the parking space management equipment due to environmental factors (such as light change, object shielding and the like). For example, if the target vehicle is a vehicle of a user to which the target parking space belongs, the license plate number of the vehicle is "B12345", and the target license plate number recognized by the parking space management device may be "B12345" (correct recognition) or "B12B 45" (wrong recognition).
It should be noted that, in the embodiment of the present application, the time for identifying the license plate number by the parking space management device is not limited. For example, the parking space management device may identify the license plate number when the vehicle enters the parking space, or the parking space management device may identify the license plate number after the vehicle is parked in the parking space.
It should be noted that each parking space has a corresponding user (user to whom the parking space belongs), and according to a license plate number provided by the user (such as a license plate number of a vehicle of the user), a parking space manager can record a corresponding relationship between the parking space and the license plate number of the user into the parking space management device. The parking space management equipment can establish the corresponding relation between the parking space and the license plate number of the user. When the parking space management device judges whether the alarm condition (whether the difference degrees between the target license plate number and the license plates are all larger than or equal to the difference threshold value) is met, the parking space management device can determine the license plate number of the user to which the target parking space belongs according to the corresponding relation, and compares the target license plate number with the license plate number of the user to which the target parking space belongs to determine whether the difference degree between the target license plate number and the license plate number of the user to which the target parking space belongs is larger than or equal to the difference threshold value.
The target space may also have at least one alternate license plate number. When the parking space management device judges whether the alarm condition (whether the difference degrees of the target license plate number and the plurality of license plate numbers are all larger than or equal to the difference threshold value) is met, the parking space management device can also judge whether the difference degrees of the target license plate number and at least one alternative license plate number are all larger than or equal to the difference threshold value.
Optionally, the parking space management device determines whether the difference degrees of the target license plate number and the at least one candidate license plate number are all greater than or equal to a difference degree threshold value according to the regular expression. For example, the parking space management device may receive at least one regular expression indicating the at least one alternative license plate number; when the target license plate number is not matched with the at least one regular expression, the parking space management device can determine that the difference degree between the target license plate number and the at least one alternative license plate number is greater than or equal to the difference degree threshold value. When the target license plate number is matched with any regular expression in the at least one regular expression, the parking space management device may determine that the difference degree between the target license plate number and the at least one alternative license plate number is not greater than or equal to the difference degree threshold value.
The at least one regular expression is used to indicate the at least one alternate license plate number. Each regular expression may be used to indicate one or more alternative license plate numbers, and the at least one regular expression used to indicate the at least one alternative license plate number may be one regular expression or multiple regular expressions.
Illustratively, the at least one regular expression includes: at least one of the first regular expression and the second regular expression. The first regular expression comprises at least one number character in the license plate number of the user to which the target parking space belongs; the second regular expression comprises at least one character in the parking space number of the target parking space. It can be seen that the first regular expression is an expression obtained by transforming the license plate number of the user to which the target parking space belongs, and the second regular expression is an expression obtained by transforming the parking space number of the target parking space.
For example, taking the license plate number of the user to which the target parking space belongs as "B12345", the first regular expression may be "B1 [ Z |2] [3| B |8] 45". The conditions that the alternative license plate number indicated by the first regular expression satisfies include: the alternative license plate number comprises six characters, wherein the first character is B, the second character is 1, the third character is Z or 2, the fourth character is 3, B or 8, the fifth character is 4, and the sixth character is 5. If the target license plate number meets the condition (if the target license plate number is B12B45), the target license plate number is matched with the first regular expression. If the target license plate number does not meet the condition (if the target license plate number is B72B46), the target license plate number is not matched with the first regular expression.
For another example, taking the parking space number of the target parking space as "F11", the second regular expression may be ". times.f 11", where ". times" represents any one or more characters. The conditions that the alternative license plate number indicated by the second regular expression satisfies include: the alternate license plate numbers include consecutive F, 1 and 1. If the target license plate number meets the condition (if the target license plate number is 11F111), the target license plate number is matched with the second regular expression. If the target license plate number does not meet the condition (if the target license plate number is 11F001), the target license plate number is not matched with the second regular expression.
It should be noted that, due to the reason of the light reflection on the ground, when no vehicle is parked in the target parking space, the parking space management device still collects the target license plate number. At this moment, the target license plate number is similar to the parking space number of the target parking space. Because the second regular expression is obtained by transforming the parking space number of the target parking space, under the condition that the vehicle is not parked on the target parking space but the parking space management equipment still collects the target license plate number, the parking space management equipment can determine that the target license plate number is matched with the second regular expression and determine that the alarm condition is not met, thereby avoiding the false alarm of the parking space management equipment.
It should be noted that the step of receiving the at least one regular expression by the parking space management device may be located in step 102, or may be before step 102 (e.g., before step 101), which is not limited in this embodiment of the present application. The at least one regular expression may be entered by a space manager in the space management device. The regular expression can be obtained according to the rule of the license plate number aimed by the false alarm information after the parking space manager analyzes the historical false alarm information.
It should be noted that, when the parking space management device determines whether the alarm condition is satisfied, it is necessary to determine whether both the first condition and the second condition are satisfied. The first condition includes: the degree of difference between the target license plate number and the license plate number of the user is greater than or equal to a degree of difference threshold, and the second condition comprises: the difference degree between the target license plate number and at least one alternative license plate number is larger than or equal to the difference degree threshold value. In the embodiment of the application, the parking space management device is used for judging whether the first condition is met or not and then judging whether the second condition is met or not. Optionally, the parking space management device may also determine whether the second condition is met first, and then determine whether the first condition is met. Or, the parking space management device may also determine whether the first condition and the second condition are satisfied at the same time. The embodiment of the application does not limit the sequence of judging whether the first condition and the second condition are met by the parking space management equipment.
For example, when judging whether the alarm condition is met, the parking space management device firstly judges whether the difference degree between the target license plate number and the license plate number of the user is greater than or equal to the difference degree threshold value; when the difference degree between the target license plate number and the license plate number of the user is larger than or equal to the difference degree threshold value, the parking space management equipment judges whether the difference degree between the target license plate number and at least one alternative license plate number is larger than or equal to the difference degree threshold value. And when the difference degree between the target license plate number and at least one alternative license plate number is greater than or equal to the difference degree threshold value, the parking space management equipment determines that the alarm condition is met. When the difference degree between the target license plate number and any one of the license plates (including the license plate number of the user and at least one alternative license plate number) is smaller than the difference degree threshold value, the parking space management equipment determines that the alarm condition is not met.
And 103, displaying the alarm information aiming at the target license plate number.
For example, the parking space management device may include a display screen, a speaker, and other units for warning, and the parking space management device may display the warning information using the units for warning.
As another example, the parking space management system may include an alarm, which may be disposed near the target parking space, and the parking space management device may be connected to the alarm. In step 103, the parking space management device may control the alarm to display the alarm information for the target license plate number. The alarm can be a sound box, a display screen, a warning lamp (the warning lamp can be arranged on the camera), and the like.
The parking space management equipment has various ways for displaying the warning information, and a plurality of ways are explained as examples below.
(1) In an optional mode, the parking space management equipment adopts a voice broadcast mode when displaying the warning information. Illustratively, taking the target license plate number "xxxxxx" as an example, "X represents an arbitrary character. After the target license plate number is determined to meet the warning condition, the parking space management equipment can control the sound box to broadcast the voice of 'please the XXXXXXXX vehicle owner to stop the parking space occupation behavior'.
(2) In another optional mode, the parking space management device adopts an image display mode when displaying the warning information. For example, after determining that the target license plate number meets the warning condition, the parking space management device may control the display screen to display a warning image of "please the xxxxxxxx vehicle owner to stop the parking space occupation behavior".
(3) In another optional mode, the parking space management device adopts a light prompting mode when displaying the warning information. For example, after it is determined that the target license plate number meets the alarm condition, the parking space management device may control a warning light installed in the target parking space to flash.
(4) In yet another alternative, the parking space management device may adopt two or three of the three aforementioned alternatives. For example, the parking space management device adopts a mode of combining voice broadcast and image display when displaying the warning information. Illustratively, the target license plate number is "xxxxxx". After confirming that target license plate number satisfies the condition of reporting an emergency and asking for help or increased vigilance, parking stall management equipment control audio amplifier reports the pronunciation of "please XXXXXXXX car owner to stop the parking stall and occupy the action" to and control display screen display shows that the content includes: and a warning image for asking the XXXXXXXX vehicle owner to stop the parking space occupation behavior.
Optionally, the parking space management device notifies the parking space manager to intervene in the field while displaying the warning information for the target license plate number. For example, the parking space management device may control the alarm to display the alarm information, and simultaneously display the alarm information on the parking space management device, and/or send the parking space number and the target license plate number of the target parking space to the user device (such as a mobile phone or a computer) of the parking space manager, so as to notify the parking space manager that the target vehicle occupies the target parking space.
And 104, prohibiting displaying the alarm information aiming at the target license plate number.
In summary, in the parking space management method provided in the embodiment of the present application, the parking space management device not only needs to determine whether the difference between the target license plate number and the license plate number of the user is greater than or equal to the difference threshold, but also needs to determine whether the difference between the target license plate number and at least one alternative license plate number is greater than or equal to the difference threshold. When the difference degree between the target license plate number and the license plate number of the user is larger than or equal to the difference degree threshold value, if the difference degree between the target license plate number and at least one alternative license plate number is not larger than or equal to the difference degree threshold value, the parking space management equipment cannot give an alarm, and therefore the probability of false alarm of the parking space management equipment is reduced.
If the difference degree between the target license plate number and the license plate number of the user is larger than or equal to the difference degree threshold value, and the difference degree between the target license plate number and at least one alternative license plate number is larger than or equal to the difference degree threshold value, the parking space management equipment gives an alarm. If the difference degree between the target license plate number and the license plate number of the user is smaller than the difference degree threshold value, the parking space management equipment cannot give an alarm.
The following describes the parking space management method provided by the present application by way of an example.
For example, assuming that the license plate number of the user to which the target parking space belongs is B12345, the at least one regular expression includes: a first regular expression B1[ Z |2] [3| B |8]45 and a second regular expression F11.
If the target vehicle is the vehicle of the user to which the target parking space belongs (the license plate number is B12345), the target license plate number identified by the parking space management device is B12B45 (the license plate number identified by mistake). Then, the space management device may determine that the degree of difference between the target license plate number B12B45 and the license plate number B12345 of the user to which the target space belongs is greater than the degree of difference threshold, and that the target license plate number B12B45 matches the first regular expression B1[ Z |2] [3| B |8]45, and that the degree of difference between the target license plate number B12B45 and at least one candidate license plate number is not greater than the degree of difference threshold. At this time, although the target license plate number B12B45 is different from the license plate number B12345 of the user belonging to the target parking space, the parking space management device determines that the alarm condition is not satisfied, and the parking space management device does not alarm, thereby avoiding the false alarm of the parking space management device.
If the target vehicle is the vehicle of the user to which the target parking space belongs (the license plate number is B12345), the target license plate number identified by the parking space management device is B12345 (the license plate number identified correctly). Then, the parking space management device may determine that the difference between the target license plate number B12345 and the license plate number B12345 of the user belonging to the target parking space is not greater than the difference threshold. At the moment, the parking space management equipment can determine that the alarm condition is not met, and the parking space management equipment cannot alarm.
If the target vehicle is not the vehicle of the user to which the target parking space belongs (for example, the license plate number is B11111), the parking space management device identifies that the target license plate number is B11111 (the license plate number is correctly identified). Then, the parking space management device may determine that the difference between the target license plate number B11111 and the license plate number B12345 of the user to which the target parking space belongs is greater than the difference threshold, and that the target license plate number B11111 is not matched with the first regular expression B1[ Z |2] [3| B |8]45 and the second regular expression F11, and the difference between the target license plate number B11111 and at least one candidate license plate number is greater than the difference threshold. At the moment, the parking space management equipment can determine that the alarm condition is met, and the parking space management equipment can alarm.
In the above embodiment, when determining whether the alarm condition is satisfied, the parking space management device needs to determine whether a second condition is satisfied, where the second condition includes: whether the difference degrees of the target license plate number and at least one alternative license plate number of the target parking space are both larger than or equal to the difference degree threshold value or not. In the above description, the parking space management device determines whether the second condition is satisfied according to at least one regular expression. Optionally, the parking space management device may also obtain at least one alternative license plate number of the target parking space, and compare the target license plate number with each alternative license plate number to determine whether the second condition is satisfied. The space management device may also determine whether the second condition is satisfied in a combination of the two ways described above.
The parking space management device has various ways of acquiring the at least one alternative license plate number, and the following explanation will be given by taking three acquisition ways as examples. The parking space management equipment can also obtain the alternative license plate number by combining at least two of the three modes.
(1) In a first optional obtaining mode, the parking space management device displays at least one piece of warning information, the warning information has a corresponding license plate number, and the at least one piece of warning information is corresponding to the at least one license plate number. And then, the parking space management equipment receives a selection instruction, wherein the selection instruction is used for indicating the false alarm information in the at least one alarm information. And finally, the parking space management equipment determines the license plate number for which the error warning information is directed as the alternative license plate number according to the selection instruction.
Optionally, the at least one warning message may be warning messages sequentially displayed by the parking space management device. For example, when an alarm is required each time, the parking space management device displays one alarm message, and after a period of time, the parking space management device displays at least one alarm message.
Optionally, the at least one warning message may be a warning message displayed by the parking space management device at one time. After the parking space management equipment displays at least one piece of alarm information in sequence, the parking space management equipment can summarize the at least one piece of alarm information and display the at least one piece of alarm information.
After the parking space management equipment displays the at least one piece of warning information, the parking space management personnel can select the mistaken warning information in the at least one piece of warning information, so that the parking space management equipment receives a selection instruction for indicating the mistaken warning information. For example, assuming that the parking space management device displays the at least one warning message in a display manner, the parking space manager may click a false warning message in the at least one warning message with a mouse, so that the parking space management device receives the selection instruction.
The parking space management personnel can determine whether the alarm information displayed by the parking space management equipment is the false alarm information in any mode. For example, the parking space manager may check with the user to which the target parking space belongs to determine whether the warning information is the false warning information.
It should be noted that before the parking space management device determines whether the second condition is met according to at least one regular expression, at least one regular expression for indicating at least one candidate license plate number needs to be obtained. In step 102, the parking space management device receives the at least one regular expression input by the parking space manager as an example. Optionally, when the parking space management device acquires the at least one regular expression, the parking space management device may also refer to the first optional acquisition mode, display at least one warning message, and receive a selection instruction for indicating a false warning message in the at least one warning message. And then, the parking space management equipment can determine the at least one regular expression according to the license plate number to which the false alarm information indicated by the selection instruction aims.
For example, as shown in fig. 2, the parking space management device may first screen (e.g., screen according to the instruction of the parking space manager) the problem parking space (e.g., target parking space), and display at least one alarm message for the license plate number of the vehicle parked at the parking space; and then, the parking space management equipment can receive a selection instruction for indicating the false alarm information in the at least one alarm information, and determine the false alarm information according to the selection instruction to realize screening and identifying errors. Finally, the parking space management device may obtain the at least one regular expression according to the false alarm information summary rules (rules for identifying errors), and add the mapping relationship between the regular expressions and the target parking space. In the subsequent step 102, the at least one regular expression may be determined based on the mapping relationship, and the determination operation in step 102 may be performed based on the regular expressions.
(2) In a second optional obtaining mode, the parking space management device displays a first license plate number, wherein in the displayed warning information, the number of the warning information aiming at the first license plate number is greater than or equal to a number threshold value. Then, the parking space management equipment receives a judgment instruction aiming at the first license plate number, and the judgment instruction is used for indicating whether the first license plate number is an alternative license plate number. And when the judgment instruction indicates that the first license plate number is the alternative license plate number, the parking space management equipment determines that the first license plate number is the alternative license plate number.
In the second acquisition mode, the parking space management device needs to determine the first license plate number according to the displayed warning information before displaying the first license plate number. For example, the parking space management device may determine a license plate number for each alarm information in the displayed alarm information, and obtain that all the displayed alarm information is for at least one license plate number. Then, the parking space management device needs to determine the number of the warning messages corresponding to each license plate number in the at least one license plate number, where the number is: the number of alarm messages shown for the license plate number. And finally, the parking space management equipment determines a first license plate number in the at least one license plate number according to the number of the alarm information corresponding to each license plate number, wherein the number of the alarm information corresponding to the first license plate number is greater than or equal to a number threshold value.
For example, assume that the presented alert information includes: alarm information 1 for license plate number B12B45, alarm information 2 for license plate number B12B45, alarm information 3 for license plate number B12B45, alarm information 4 for license plate number B12B45, and alarm information 5 for license plate number B11111. As can be seen, the number of pieces of alarm information for the license plate number B12B45 is 4 (the number of pieces of alarm information corresponding to the license plate number B12B45 is 4), and the number of pieces of alarm information for the license plate number B11111 is 1 (the number of pieces of alarm information corresponding to the license plate number B11111 is 1). If the quantity threshold is 2, then the slot management device may determine that license plate number B12B45 is the first license plate number.
After the parking space management equipment displays the first license plate number, the parking space management personnel can judge whether the first license plate number is the spare license plate number or not and operate on the parking space management equipment according to the judgment result so that the parking space management equipment receives a judgment instruction for indicating whether the first license plate number is the spare license plate number or not.
For example, assuming that the parking space management device displays the first license plate number in a display manner, the parking space management device may further display selection buttons of "yes" and "no" when displaying the first license plate number. The parking space manager can click the 'yes' selection button or the 'no' selection button by using a mouse, so that the parking space management equipment receives the judgment instruction. When the parking space manager clicks the 'yes' selection button by using a mouse, the judgment instruction received by the parking space management equipment is used for indicating that the first license plate number is the alternative license plate number; when the parking space manager clicks the 'no' selection button by using a mouse, the judgment instruction received by the parking space management equipment is used for indicating that the first license plate number is not the alternative license plate number.
The parking space manager can determine whether the first license plate number is the alternative license plate number in any way. For example, the parking space manager may check with the user to which the target parking space belongs to determine whether the first license plate number is the false alarm information.
(3) In a third optional obtaining mode, the parking space management device receives a license plate number instruction, and the license plate number instruction is used for indicating at least one target license plate number. And then, the parking space management equipment determines that at least one target license plate number indicated by the license plate number instruction is an alternative license plate number. In the third acquisition mode, the parking space management equipment only needs to receive the license plate number instruction input by the parking space manager and determine the alternative license plate number according to the license plate number instruction.
Optionally, the license plate number instruction may include the at least one target license plate number. At the moment, the parking space management equipment can obtain the at least one target license plate number by analyzing the license plate number command.
Further, the parking space management device may periodically update the content related to the at least one alternative license plate number in the alarm condition. For example, the parking space management device may periodically update the at least one regular expression, and for example, the parking space management device may periodically update the at least one candidate license plate number.
The following describes an exemplary parking space management method provided by the present application with reference to fig. 3 and 4.
As shown in fig. 3, after the parking space management device displays the warning information for the license plate number of a certain vehicle parked in the target parking space, the parking space manager may determine whether the license plate number targeted by the warning information is correctly identified.
When the license plate number is correctly identified, the parking space manager can further determine whether the license plate number is the license plate number of the user of the target parking space. If the license plate number targeted by the warning information is the license plate number of the user, the parking space management personnel can input the license plate number of the license plate number user into the parking space management equipment. At the moment, the parking space management equipment can bind the license plate number input by the parking space management personnel as the license plate number of the user with the target parking space, so that the license plate number is bound with the target parking space. The license plate number of the user obtained by the parking space management device in step 102 may also be obtained in this manner. If the license plate number aimed by the warning information is not the license plate number of the user, the parking space manager can go to the site of the target parking space to process the vehicle occupying the target parking space.
When the license plate number targeted by the warning information is identified incorrectly, the parking space manager can judge whether the vehicle parked in the current target parking space is the vehicle of the user.
If the vehicle parked in the target parking space is the vehicle of the user, the parking space manager can determine that the warning information is the false warning information and operate on the parking space management equipment, so that the parking space management equipment receives the selection instruction. The selection instruction is used for indicating that the alarm information is false alarm information. Then, the parking space management device may use the license plate number to which the warning information is directed as the first candidate license plate number of the target parking space, for example, add a mapping relationship between the target parking space and the first candidate license plate number.
If the vehicle parked in the target parking space is not the user's vehicle, the parking space manager may determine whether the current target parking space is an empty space. If the target parking space is an empty parking space, the warning information is error warning information, and at the moment, the parking space management personnel can also operate on the parking space management equipment so that the parking space management equipment receives a selection instruction. The selection instruction is used for indicating that the alarm information is false alarm information. Then, the parking space management device may use the license plate number to which the warning information is directed as a second candidate license plate number of the target parking space, for example, add a mapping relationship between the target parking space and the second candidate license plate number. If the target parking space is not an empty parking space, the warning information is not error warning information, and at the moment, parking space management personnel can go to the site of the target parking space to process the vehicle occupying the target parking space.
As shown in fig. 4, after the target vehicle is parked in the target parking space, the camera in the parking space management system collects the target license plate number of the target vehicle, and reports the target license plate number to the parking space management device. It can be seen that the parking space management equipment identifies the target license plate number through the camera.
Then, the parking space management device may determine whether the target vehicle is a vehicle of the user, for example, the parking space management device may determine whether the target license plate number is a license plate number of the user of the target parking space; when the target license plate number is the license plate number of the user of the target parking space (the difference degree between the target license plate number and the license plate number of the user is smaller than the difference degree threshold value), the parking space management equipment determines that the target vehicle is the vehicle of the user and can forbid displaying of the alarm information aiming at the target license plate number.
When the target license plate is not the license plate of the user of the target parking space (the difference between the target license plate and the license plate of the user is greater than or equal to the difference threshold), the parking space management device may further determine whether the target license plate meets the filtering rule, such as whether the target license plate is different from at least one alternative license plate of the target parking space (the difference between the target license plate and the at least one alternative license plate is greater than or equal to the difference threshold). When the target license plate number is the same as a certain alternative license plate number, the parking space management equipment can determine that the target license plate number meets the filtering rule and does not display the warning information aiming at the target license plate number. When the target license plate number is different from each alternative license plate number, the parking space management equipment can determine that the target license plate number does not accord with the filtering rule, and can display the alarm information aiming at the target license plate number.
The embodiment of the application provides a parking space management device, as shown in fig. 5, this parking space management device can include:
the identification module 201 is used for identifying a target license plate number of a target vehicle parked on a target parking space;

In summary, in the parking space management device provided in the embodiment of the present application, the parking space management device not only needs to determine whether the difference between the target license plate number and the license plate number of the user is greater than or equal to the difference threshold, but also needs to determine whether the difference between the target license plate number and at least one alternative license plate number is greater than or equal to the difference threshold. When the difference degree between the target license plate number and the license plate number of the user is larger than or equal to the difference degree threshold value, if the difference degree between the target license plate number and at least one alternative license plate number is not larger than or equal to the difference degree threshold value, the parking space management equipment cannot give an alarm, and therefore the probability of false alarm of the parking space management equipment is reduced.
