Description

Technical Field

[0001] The present application relates to the field of parking detection technology, and more specifically, to a method, system, and device for obtaining image evidence of vehicles entering and exiting parking spaces. Background Art

[0002] It is very necessary to take pictures of the vehicle when it enters and exits the parking space to leave visual evidence of the vehicle entering and exiting the parking space.

[0003] Existing methods generally use high-mounted cameras to capture visual evidence of vehicles entering and exiting parking spaces. These cameras have inherent recognition capabilities and, upon detecting a vehicle entering or exiting a parking space, take a photo of the parking space. However, sometimes the camera's lens is obscured by foliage, making it impossible to detect the vehicle entering or exiting the parking space. Consequently, no visual evidence of the vehicle entering or exiting the parking space is captured. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a method, system and equipment for obtaining image evidence of vehicles entering and exiting parking spaces. By introducing parking space detection equipment as an additional detection medium for vehicles entering and exiting parking spaces, even if the lens of the high-position recognition camera is partially blocked by objects such as leaves and cannot identify the vehicles entering and exiting the parking space, the high-position recognition camera can still take pictures of the parking space and obtain image evidence of the vehicles entering and exiting the parking space.

[0005] In a first aspect, an embodiment of the present application provides a method for obtaining image evidence of a vehicle entering or exiting a parking space, the method comprising:

[0006] At every preset first time interval, the high-position recognition camera takes a picture of the parking area monitored by itself to obtain a first image, records a first photographing moment of the first image, and uploads the first image and the first photographing moment to a server, wherein the parking area includes at least one parking space, and each parking space is provided with a parking space detection device for detecting whether a target event occurs in the parking space, wherein the target event includes a vehicle entering or exiting the parking space;

[0007] If the parking space detection device detects that the target event occurs in the parking space, the parking space detection device records the time of occurrence of the target event, and sends a target event signal and the time of occurrence to the server;

[0008] The server responds to the target event signal, issues a photographing instruction to the high-level recognition camera, and determines a first image serving as image evidence of the target event based on the occurrence time and a first photographing time adjacent to the occurrence time;

[0009] The high-position recognition camera responds to the photographing instruction, takes a photograph of the parking area, obtains a second image as image evidence of the target event, and uploads the second image to the server.

[0010] In one possible implementation, the method further includes:

[0011] When the server receives the occurrence time, it compares the occurrence time with the current Internet standard time. If the absolute value of the time difference between the occurrence time and the current Internet standard time is greater than the preset time difference, the time of the parking space detection device is calibrated based on the Internet standard time, wherein the preset time difference is greater than 0.

[0012] In a possible implementation, the absolute value of the preset time difference is less than half of the first time interval; and the server determines, based on the occurrence moment and a first photographing moment adjacent to the occurrence moment, a first image serving as visual evidence of the target event, including:

[0013] If the server determines that the time difference between the occurrence moment and the first target photographing moment and the time difference between the second target photographing moment and the occurrence moment are both greater than the preset time difference, the server determines the first image photographed at the first target photographing moment as the first image serving as image evidence of the target event, wherein the first target photographing moment is the target photographing moment before the occurrence moment, the second target photographing moment is the target photographing moment after the occurrence moment, and the target photographing moment is the first photographing moment adjacent to the occurrence moment;

[0014] If the server determines that the time difference between the first target photographing moment and the occurrence moment is less than the preset time difference, the server determines the first image photographed at the first target photographing moment and the first image photographed at the third target photographing moment as the first image serving as the image evidence of the target event, wherein the third target photographing moment is the first photographing moment immediately adjacent to and before the first target photographing moment;

[0015] If the server determines that the time difference between the second target photographing moment and the occurrence moment is less than the preset time difference, the server will determine the first image with the photographing moment of the first target and the first image with the photographing moment of the second target as the first image serving as image evidence of the target event.

[0016] In one possible implementation, for each parking space, the high-position recognition camera can identify whether the target event occurs in the parking space when the display portion corresponding to the parking space in its lens is not blocked; the method further includes:

[0017] If the high-position recognition camera detects that the target event occurs in any of the parking spaces, it takes a picture of the parking area to obtain a third image, records a second photographing time of the third image, and uploads the third image and the second photographing time to the server;

[0018] Before the server responds to the target event signal, issues a photographing instruction to the high-level recognition camera, and determines a first image serving as image evidence of the target event based on the occurrence time and a first photographing time adjacent to the occurrence time, the method further includes:

[0019] The server determines whether the third image and the shooting time of the third image uploaded by the high-position recognition camera are received within a preset time period before or after receiving the target event signal;

[0020] If the server does not receive the third image and the second photo-taking moment uploaded by the high-position recognition camera within the preset time period before or after receiving the target event signal, the server executes the step of responding to the target event signal, issuing a photo-taking instruction to the high-position recognition camera, and determining the first image as image evidence of the target event based on the occurrence time and the first photo-taking moment adjacent to the occurrence time.

[0021] In a possible implementation, after the server determines whether the third image uploaded by the high-level recognition camera and the shooting time of the third image are received within a preset time period before or after receiving the target event signal, the method further includes:

[0022] If the server receives the third image uploaded by the high-position recognition camera and the second photo-taking moment within the preset time period before or after receiving the target event signal, the third image is determined as image evidence of the target event.

[0023] In a second aspect, an embodiment of the present application further provides a system for acquiring image evidence of a vehicle entering or exiting a parking space, the system comprising:

[0024] a high-position recognition camera, configured to photograph a parking area monitored by the camera at predetermined first time intervals to obtain a first image, record a first photographing moment of the first image, and upload the first image and the photographing moment of the first image to a server, wherein the parking area includes at least one parking space, and each parking space is provided with a parking space detection device for detecting whether a target event occurs in the parking space, wherein the target event includes a vehicle entering or exiting the parking space;

[0025] The parking space detection device is configured to record the time of occurrence of the target event if it is detected that the target event occurs in the parking space, and to send a target event signal and the time of occurrence of the target event to the server;

[0026] The server is configured to respond to the target event signal, issue a photographing instruction to the high-level recognition camera, and determine a first image serving as image evidence of the target event based on the occurrence time and a first photographing time adjacent to the occurrence time;

[0027] The high-position recognition camera is further configured to respond to the photographing instruction, take a photograph of the parking area, obtain a second image as visual evidence of the target event, and upload the second image to the server.

[0028] In a possible embodiment, the server is further used to compare the occurrence time with the current Internet standard time when receiving the occurrence time, and if the absolute value of the time difference between the occurrence time and the current Internet standard time is greater than a preset time difference, calibrate the time of the parking space detection device based on the Internet standard time, wherein the preset time difference is greater than 0.

[0029] In a possible implementation, the absolute value of the preset time difference is less than half of the first time interval; and when the server determines the first image serving as image evidence of the target event based on the occurrence moment and a first photographing moment adjacent to the occurrence moment, the server is specifically configured to:

[0030] If the server determines that the time difference between the occurrence moment and the first target photographing moment and the time difference between the second target photographing moment and the occurrence moment are both greater than the preset time difference, the server determines the first image whose photographing moment is the first target photographing moment as the first image serving as the image evidence of the target event, wherein the first target photographing moment is the target photographing moment before the occurrence moment, the second target photographing moment is the target photographing moment after the occurrence moment, and the target photographing moment is the first photographing moment adjacent to the occurrence moment;

[0031] If the server determines that the time difference between the first target photographing moment and the occurrence moment is less than the preset time difference, the server determines the first image photographed at the first target photographing moment and the first image photographed at the third target photographing moment as the first image serving as the image evidence of the target event, wherein the third target photographing moment is the first photographing moment immediately adjacent to and before the first target photographing moment;

[0032] If the server determines that the time difference between the second target photographing moment and the occurrence moment is less than the preset time difference, the first image with the photographing moment of the first target and the first image with the photographing moment of the second target are determined as the first image serving as image evidence of the target event.

[0033] In a possible implementation, for each of the parking spaces, the high-position recognition camera can identify whether the target event occurs in the parking space when a display portion corresponding to the parking space in its own lens is not blocked;

[0034] The high-position recognition camera is further configured to, if the target event is detected to occur in any of the parking spaces, photograph the parking area to obtain a third image, record a second photographing time of the third image, and upload the third image and the second photographing time to the server;

[0035] The server is further configured to, in response to the target event signal, issue a photographing instruction to the high-level recognition camera, and, before determining a first image serving as visual evidence of the target event based on the occurrence moment and a first photographing moment adjacent to the occurrence moment, determine whether the third image uploaded by the high-level recognition camera and the photographing moment of the third image are received within a preset time period before or after receiving the target event signal;

[0036] If the server does not receive the third image and the second photo-taking moment uploaded by the high-position recognition camera within the preset time period before or after receiving the target event signal, it is also used to execute the step of the server responding to the target event signal, issuing a photo-taking instruction to the high-position recognition camera, and determining the first image as image evidence of the target event based on the occurrence time and the first photo-taking moment adjacent to the occurrence time.

[0037] In a possible embodiment, the server is further configured to determine the third image as image evidence of the target event if the third image uploaded by the high-position recognition camera and the second photo-taking moment are received within the preset time period before or after receiving the target event signal.

[0038] In a third aspect, an embodiment of the present application further provides an electronic device comprising: a processor, a storage medium and a bus, wherein the storage medium stores machine-readable instructions executable by the processor. When the electronic device is running, the processor communicates with the storage medium via the bus, and the processor executes the machine-readable instructions to perform the steps of the method for obtaining image evidence of a vehicle entering and exiting a parking space as described in any one of the first aspects.

[0049] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0050] To facilitate understanding of this embodiment, a method, system, and device for obtaining image evidence of a vehicle entering and exiting a parking space provided in an embodiment of the present application are introduced in detail.

[0051] Reference Figure 1 FIG. 1 is a flowchart of a method for obtaining image evidence of a vehicle entering or exiting a parking space provided in an embodiment of the present application. The method includes:

[0052] S101. At every preset first time interval, the high-position recognition camera takes a picture of the parking area it monitors to obtain a first image, and records a first photographing moment of the first image, and uploads the first image and the first photographing moment to a server, wherein the parking area includes at least one parking space, and for each of the parking spaces, the parking space is provided with a parking space detection device for detecting whether a target event occurs in the parking space, and the target event includes a vehicle entering and a vehicle exiting.

[0053] The high-position recognition camera has a time function.

[0054] Exemplarily, the first time interval is 10 minutes.

[0055] Exemplarily, the parking space detection device may be a geomagnetic or ultrasonic detection device.

[0056] S102: If the parking space detection device detects that the target event occurs in the parking space, the parking space detection device records the time of occurrence of the target event, and sends a target event signal and the time of occurrence to the server.

[0057] The parking space detection device has a time function.

[0058] Sending the target event signal indicates that there is currently a vehicle entering or exiting the parking space, and the parking area needs to be photographed.

[0059] S103: The server responds to the target event signal, issues a photo-taking instruction to the high-position recognition camera, and determines a first image as image evidence of the target event based on the occurrence time and a first photo-taking time adjacent to the occurrence time.

[0060] S104: The high-position recognition camera responds to the photographing instruction, photographs the parking area, obtains a second image as image evidence of the target event, and uploads the second image to the server.

[0061] In one possible implementation, the method further includes:

[0062] When the server receives the occurrence time, it compares the occurrence time with the current Internet standard time. If the absolute value of the time difference between the occurrence time and the current Internet standard time is greater than the preset time difference, the time of the parking space detection device is calibrated based on the Internet standard time, wherein the preset time difference is greater than 0.

[0063] Exemplarily, the parking space detection device may have its own battery to power itself. Preferably, the battery may be a lithium battery.

[0064] In addition, the server may calibrate the time of the high-position recognition camera based on the current Internet time at every preset second time interval.

[0065] In a possible implementation, the absolute value of the preset time difference is less than half of the first time interval; and the server determines, based on the occurrence moment and a first photographing moment adjacent to the occurrence moment, a first image serving as visual evidence of the target event, including:

[0066] If the server determines that the time difference between the occurrence moment and the first target photographing moment and the time difference between the second target photographing moment and the occurrence moment are both greater than the preset time difference, the server determines the first image photographed at the first target photographing moment as the first image serving as image evidence of the target event, wherein the first target photographing moment is the target photographing moment before the occurrence moment, the second target photographing moment is the target photographing moment after the occurrence moment, and the target photographing moment is the first photographing moment adjacent to the occurrence moment;

[0067] The time difference between the occurrence time and the first target photographing time is the occurrence time minus the first target photographing time.

[0068] The time difference between the second target photographing time and the occurrence time is the second target photographing time minus the occurrence time.

[0069] Reference Figure 2 As shown, it is a timing diagram provided by an embodiment of the present application in which the time difference between the occurrence moment and the first target photographing moment and the time difference between the second target photographing moment and the occurrence moment are both greater than the preset time difference. Figure 2 In the figure, Ts1 is the first target photographing moment, Tm is the occurrence moment, Ts2 is the second target photographing moment, and the time difference between Tm and the left boundary of the rectangular box at the position of Tm and the time difference between the right boundary of the rectangular box at the position of Tm and Tm both represent the preset time difference.

[0070] In order to surely reflect the entry and exit of vehicles in the parking space, the second image and the first image taken at the first target photographing time are selected as image evidence of the target event.

[0071] If the server determines that the time difference between the first target photographing moment and the occurrence moment is less than the preset time difference, the server determines the first image photographed at the first target photographing moment and the first image photographed at the third target photographing moment as the first image serving as the image evidence of the target event, wherein the third target photographing moment is the first photographing moment immediately adjacent to and before the first target photographing moment;

[0072] Reference Figure 3 As shown, it is a timing diagram provided by an embodiment of the present application in which the time difference between the occurrence moment and the first target photographing moment is less than the preset time difference. Figure 3 In the figure, Ts1 is the first target photographing moment, Tm is the occurrence moment, Ts2 is the second target photographing moment, and the time difference between Tm and the left boundary of the rectangular box at the position of Tm and the time difference between the right boundary of the rectangular box at the position of Tm and Tm both represent the preset time difference.

[0073] In order to ensure that the vehicles entering and exiting the parking space are reflected, the second image, the first image taken at the time of the first target, and the first image taken at the time of the third target are selected as image evidence of the target event.

[0074] If the server determines that the time difference between the second target photographing moment and the occurrence moment is less than the preset time difference, the server will determine the first image with the photographing moment of the first target and the first image with the photographing moment of the second target as the first image serving as image evidence of the target event.

[0075] Reference Figure 4 As shown, it is a timing diagram of an embodiment of the present application in which the time difference between the second target photographing moment and the occurrence moment is less than the preset time difference. Figure 4 In the figure, Ts1 is the first target photographing moment, Tm is the occurrence moment, Ts2 is the second target photographing moment, and the time difference between Tm and the left boundary of the rectangular box at the position of Tm and the time difference between the right boundary of the rectangular box at the position of Tm and Tm both represent the preset time difference.

[0076] In order to ensure that the vehicles entering and exiting the parking space are reflected, the second image, the first image taken at the time of the first target, and the first image taken at the time of the second target are selected as image evidence of the target event.

[0077] In one possible implementation, for each parking space, the high-position recognition camera can identify whether the target event occurs in the parking space when the display portion corresponding to the parking space in its lens is not blocked; the method further includes:

[0078] If the high-position recognition camera detects that the target event occurs in any of the parking spaces, it takes a picture of the parking area to obtain a third image, records a second photographing time of the third image, and uploads the third image and the second photographing time to the server;

[0079] Before the server responds to the target event signal, issues a photographing instruction to the high-level recognition camera, and determines a first image serving as image evidence of the target event based on the occurrence time and a first photographing time adjacent to the occurrence time, the method further includes:

[0080] The server determines whether the third image and the shooting time of the third image uploaded by the high-position recognition camera are received within a preset time period before or after receiving the target event signal;

[0081] If the server does not receive the third image and the second photo-taking moment uploaded by the high-position recognition camera within the preset time period before or after receiving the target event signal, the server executes the step of responding to the target event signal, issuing a photo-taking instruction to the high-position recognition camera, and determining the first image as image evidence of the target event based on the occurrence time and the first photo-taking moment adjacent to the occurrence time.

[0082] In a possible implementation, after the server determines whether the third image uploaded by the high-level recognition camera and the shooting time of the third image are received within a preset time period before or after receiving the target event signal, the method further includes:

[0083] If the server receives the third image uploaded by the high-position recognition camera and the second photo-taking moment within the preset time period before or after receiving the target event signal, the third image is determined as image evidence of the target event.

By introducing a parking space detection device as an additional detection medium for vehicles entering and exiting parking spaces, even if the lens of a high-position recognition camera is partially blocked by objects such as leaves and is unable to recognize the vehicles entering and exiting the parking space, the high-position recognition camera can still take pictures of the parking space to obtain image evidence of the vehicles entering and exiting the parking space.

[0087] The parking space detection device is configured to record the time of occurrence of the target event if it is detected that the target event occurs in the parking space, and to send a target event signal and the time of occurrence of the target event to the server;

[0088] The server is configured to respond to the target event signal, issue a photographing instruction to the high-level recognition camera, and determine a first image serving as image evidence of the target event based on the occurrence time and a first photographing time adjacent to the occurrence time;

[0089] The high-position recognition camera is further configured to respond to the photographing instruction, take a photograph of the parking area, obtain a second image as visual evidence of the target event, and upload the second image to the server.

[0090] In a possible embodiment, the server is further used to compare the occurrence time with the current Internet standard time when receiving the occurrence time, and if the absolute value of the time difference between the occurrence time and the current Internet standard time is greater than a preset time difference, calibrate the time of the parking space detection device based on the Internet standard time, wherein the preset time difference is greater than 0.

[0091] In a possible implementation, the absolute value of the preset time difference is less than half of the first time interval; and when the server determines the first image serving as image evidence of the target event based on the occurrence moment and a first photographing moment adjacent to the occurrence moment, the server is specifically configured to:

[0092] If the server determines that the time difference between the occurrence moment and the first target photographing moment and the time difference between the second target photographing moment and the occurrence moment are both greater than the preset time difference, the server determines the first image whose photographing moment is the first target photographing moment as the first image serving as the image evidence of the target event, wherein the first target photographing moment is the target photographing moment before the occurrence moment, the second target photographing moment is the target photographing moment after the occurrence moment, and the target photographing moment is the first photographing moment adjacent to the occurrence moment;

[0093] If the server determines that the time difference between the first target photographing moment and the occurrence moment is less than the preset time difference, the server determines the first image photographed at the first target photographing moment and the first image photographed at the third target photographing moment as the first image serving as the image evidence of the target event, wherein the third target photographing moment is the first photographing moment immediately adjacent to and before the first target photographing moment;

[0094] If the server determines that the time difference between the second target photographing moment and the occurrence moment is less than the preset time difference, the first image with the photographing moment of the first target and the first image with the photographing moment of the second target are determined as the first image serving as image evidence of the target event.

[0095] In a possible implementation, for each of the parking spaces, the high-position recognition camera can identify whether the target event occurs in the parking space when a display portion corresponding to the parking space in its own lens is not blocked;

[0096] The high-position recognition camera is further configured to, if the target event is detected to occur in any of the parking spaces, photograph the parking area to obtain a third image, record a second photographing time of the third image, and upload the third image and the second photographing time to the server;

[0098] If the server does not receive the third image and the second photo-taking moment uploaded by the high-position recognition camera within the preset time period before or after receiving the target event signal, it is also used to execute the step of the server responding to the target event signal, issuing a photo-taking instruction to the high-position recognition camera, and determining the first image as image evidence of the target event based on the occurrence time and the first photo-taking moment adjacent to the occurrence time.
