In the existing parking space display method, a visual area of an electronic device usually displays a pattern block for representing each parking space, and displays whether the parking space is occupied or not by using two different colors. For example, a certain picture block corresponds parking stall 1, and when parking stall 1 was taken up, this picture block was grey, when parking stall 1 was not taken up, this picture block was yellow.

In view of the above, the present application provides a parking space display method for a parking area, which determines a target parking space area of a target parking space to be updated from a visible area of a currently displayed parking area map; and rendering the cached parking space real-scene image of the target parking space to the target parking space area.

Referring to fig. 1a, fig. 1a is a block diagram of a parking space management system according to an exemplary embodiment of the present disclosure.

This parking stall management system includes: the system comprises an electronic device, a server and at least one monitoring device.

1) Monitoring device

Wherein the at least one monitoring device is deployed in a parking area. The sum of all monitoring device fields of view can cover all parking spots. Each monitoring device is used for acquiring a parking space real-scene image of a parking space in the current visual field of the monitoring device.

Here, the parking area refers to an area for parking, for example, the parking area may be a parking lot, a temporary parking place, or the like. The parking area is only exemplified here, and is not particularly limited.

In an alternative implementation, the monitoring device may periodically acquire real-scene images of the parking space in the current view. Of course, the monitoring device may also capture the parking space live-action image of the current frame when the monitored parking space live-action image of the current frame is inconsistent with the parking space live-action image of the previous frame.

After the monitoring equipment captures the parking space live-action image, the captured parking space live-action image can be sent to the server for storage. Certainly, in practical application, the monitoring device may also send the relevant information of the parking space live-action image to the server for storage. Wherein, the relevant information of the parking space live-action image can include: the method comprises the following steps of capturing the parking space live-action image, capturing the mark of the monitoring equipment for capturing the parking space live-action image and the like. Here, the information related to the parking space live-action image is only exemplarily described, and is not particularly limited.

2) Server

The server is used for storing the parking space real-scene images captured by the monitoring equipment and relevant information of the parking space real-scene images and providing the parking space real-scene images for the electronic equipment.

3) Electronic device

A display window is disposed on the electronic device. The electronic equipment is loaded with the parking area map, and a user can display the whole parking area map or part of the parking area map on the display window through dragging, zooming in or zooming out and the like. For convenience of description, an area surrounded by the display window on the parking area map is referred to as a visible area of the parking area map.

It should be noted that the parking space display method for the parking area provided by the application can be applied to scenes of various parking areas. Such as in parking lots, garages, temporary parking areas on both sides of a roadway, etc. Here, the application scenario of the present application is merely exemplary and is not specifically limited.

Some concepts related to the present application are explained below.

1. Visual field of parking space regional map: the area enclosed by the display window of the electronic device on the parking area map is called the visible area of the parking area map. As shown in fig. 1b, the area enclosed by the dashed box shown in fig. 1b is visible.

The parking area map is a picture indicating the distribution of parking spaces. The parking area map is a picture capable of displaying the distribution of real parking spaces. For example, the parking area map may be a map in the conventional sense, i.e., the map not only shows the distribution of real parking spaces, but also shows the relevant geographical location information of the parking area, etc. Of course, the parking area map may also be a map in a broad sense, that is, the parking area map may be a picture of any pattern, but the picture may show the distribution of real parking spaces. Here, the parking area map is merely exemplary and is not particularly limited.

2. The parking space is regional: the parking space area is an area used for rendering a parking space real-scene image on a parking space area map. For example, as shown in fig. 1b, the gray squares in fig. 1b are parking space areas.

3. Parking space live-action image: the image of the parking stall that supervisory equipment shot. As indicated in fig. 1 b.

Referring to fig. 2, fig. 2 is a flowchart illustrating a parking space display method for a parking area according to an exemplary embodiment of the present application, where the method is applicable to an electronic device and may include the following steps.

Step 201: and the electronic equipment determines a target parking space area of the target parking space to be updated from the visual area of the currently displayed parking area map.

Step 202: and the electronic equipment renders the cached parking space real-scene image of the target parking space to the target parking space area.

In the embodiment of the application, the parking space display method for realizing the parking area comprises two conditions.

The first situation is that when it is monitored that the hierarchy updating operation for the parking area map meets a first preset condition (for example, the hierarchy of the parking area map is changed to an appointed hierarchy), the electronic device renders the cached parking space real-scene image of at least one parking space in the visible area of the parking area map onto the parking space area of the at least one parking space. And when the electronic device monitors that the hierarchy updating operation for the parking area map meets a second preset condition (for example, the hierarchy of the parking area map is changed from a specified hierarchy to a non-specified hierarchy), clearing the parking space live-action image of the visible field of the parking area map.

The second situation is that the parking space included in the visible area of the parking area map currently displayed by the electronic device is rendered with a parking space real image, and since the parking space real image of the parking area is continuously updated, the electronic device needs to update the rendered parking space real image, so that the rendered parking space real image is consistent with the real parking space real image.

The following two cases will be described separately.

1. In the first case:

1.1) in the first case, the above-mentioned "step 201: and determining a target parking space area of the target parking space to be updated from the visual area of the currently displayed parking area map.

In the existing Geographic Information System (GIS), when implemented: the map data in the GIS display side (i.e. the electronic device of the present application) is typically grid, specifically map slice data. The map slicing is to use a professional map cutting tool to make original map data into a plurality of levels of map layers according to the superposition information of the map, and the map layers of different levels have different scales. For example, the map information is displayed in more detail when the map level of the map is larger.

The user can adjust the map hierarchy where the map is located through a hierarchy updating operation (such as zooming out and zooming in) to acquire the map information required by the user. For example, the user can raise the level of the parking area map by the zoom-in operation. The user can lower the hierarchy of the parking area map by the zoom-out operation.

The electronic device can monitor the level updating operation aiming at the parking area map, and under the condition that the level updating operation aiming at the parking area map is detected to meet the preset condition, at least one parking space contained in the visible area of the parking area map is determined as a target parking space needing to be updated.

1.11) detecting that the hierarchy updating operation for the parking area map satisfies a preset condition

Optionally, the preset condition may be: the level of the parking area map is changed to a specified level.

When the electronic equipment detects that the level of the parking area map is enlarged or reduced to a specified level, the cached parking space real-scene image of the target parking space is rendered to the target parking space area. When the electronic equipment detects that the level of the parking area map is enlarged or reduced to a non-specified level, the parking space live-action image rendering is not carried out.

The designated level refers to a level which has a display scale and can support a user to clearly see the parking space live-action image.

For example, the designated hierarchy may be 22 layers and/or 23 layers, etc. The 22 or 23 layers of the parking area map are layers with a larger display scale, and the parking space live-action image is rendered on the layers, so that the user can see the parking space live-action image more clearly. Of course, in practical applications, other hierarchies are possible, which are only illustrated by way of example and are not specifically applied.

Specifically, when the electronic device monitors that the hierarchy of the parking area map is enlarged or reduced to 22 or 23 levels, it may be determined that the electronic device monitors that the hierarchy update operation for the parking area map satisfies a preset condition. This is merely an example and is not particularly limited.

1.12) determining at least one parking space contained in the visual area of the parking area map as a target parking space to be updated.

Step 1.12) is explained below by step a1 to step a 2.

Step A1, the electronic device determines a viewable area of a parking area map.

Referring to fig. 3, the electronic device may determine the current viewable area as follows.

The rectangle ABCD is a display window of the electronic equipment, and the rectangle EFGH is a parking area map.

The electronic equipment can firstly acquire the pixel coordinates of the center of the display window in the parking area map and acquire the number of pixels occupied by the long edge and the wide edge of the display window.

Then, the electronic device determines the pixel coordinates of the four vertices A, B, C, D of the display window based on the pixel coordinates of the center of the display window and the number of pixels occupied by the long side and the wide side of the display window.

The electronic device determines the area on the parking area map framed by the display window based on the pixel coordinates of the four vertices of the display window, where the framed area is the visible area described above.

And step A2, the electronic equipment determines the unrendered parking spaces contained in the determined visual area as target parking spaces needing to be updated.

In an alternative implementation manner, the electronic device may determine all parking spaces included in the visible area of the parking area map as target parking spaces to be updated.

In another alternative implementation manner, the electronic device may determine a part of parking spaces included in the visible area of the parking area map as target parking spaces to be updated. For example, the user may select a parking space that needs to be rendered in the visual area, and the electronic device may use the parking space selected by the user as a target parking space that needs to be updated.

The determination of the target parking space is only exemplified and not particularly limited.

1.2) in the first case, step 202 is implemented, as follows: and the electronic equipment renders the cached parking space real-scene image of the target parking space to the target parking space area. "

Step 202 is described below by steps B1 through B2.

Step B1: and the electronic equipment acquires the cached parking space live-action image of the target parking space.

During implementation, the corresponding relation between the parking space identification and the parking space live-action image is cached by the electronic equipment, after the target parking space is determined, the parking space identification of the target parking space can be obtained from the parking area map, and the parking space live-action image corresponding to the target parking space identification is searched in the corresponding relation.

Step B2: and the electronic equipment preprocesses the parking space live-action image so as to enable the preprocessed parking space live-action image to be matched with the shape of the target parking space area. And rendering the preprocessed parking space live-action image to the target parking space area.

The "shape matching between the preprocessed parking space live-action image and the target parking space region" may mean that the preprocessed parking space live-action image and the target parking space region have the same shape and size; or the size of the shape of the preprocessed parking space live-action image is smaller than that of the target parking space area, and the shape of the preprocessed parking space live-action image can be completely covered by the shape of the target parking space area; the parking space real-scene image after the preprocessing and the target parking space image area can also be in the same shape but different sizes. For example, the target parking space image region may include a preprocessed parking space live view image, and the like, and here, the "shape matching between the preprocessed parking space live view image and the target parking space region" is merely exemplarily described, and is not specifically limited.

In this embodiment of the application, when the parking space live-action image is preprocessed, the electronic device may preprocess the parking space live-action image by adjusting the size and/or the rotation angle of the parking space live-action image.

1) And adjusting the size of the parking space live-action image.

When the parking space real-scene image size is achieved, the parking space real-scene image size is adjusted, and therefore the adjusted parking space real-scene image size is matched with the size of the target parking space area.

The "matching between the adjusted parking space real-scene image size and the target parking space area size" may mean that the adjusted parking space real-scene image size is completely the same as the target parking space area size, or that the adjusted parking space real-scene image size is a size obtained by scaling down the size of the target parking space area, for example, the adjusted parking space real-scene image size is half of the size of the target parking space area, and the target parking space area may include the adjusted parking space real-scene image. Here, the "size of the adjusted parking space live view image matches the size of the target parking space region" is only exemplarily described, and is not specifically limited.

Next, the following describes in detail "adjusting the size of the parking space live-view image so that the adjusted size of the parking space live-view image matches the size of the target parking space area" in steps C1 to C2.

And step C1, the electronic equipment can determine the size of the target parking space area based on the vertex coordinates of the target parking space area.

In implementation, the electronic device may select a target vertex from the vertices of the target parking space region. And then calculating the length and the width of the target parking space area based on the coordinates of the target vertex and the coordinates of two vertexes adjacent to the target vertex.

For example, as shown in fig. 4, the rectangle in fig. 4 is a parking space area.

The 4 vertexes of the parking space area are respectively the vertexes A, B, C and D. The coordinates of vertex A are [3,0], the coordinates of vertex B are [11,6], the coordinates of vertex C are [8,10], and the coordinates of vertex D are [0,4 ].

The electronic device may calculate the long side of the target parking space area by using the vertex C as a target vertex and based on the coordinates of the vertex C and the coordinates of the vertex D adjacent to the vertex C.

That is, the long side is:

the electronic device may calculate the width of the target parking space area based on the coordinates of the vertex C and the coordinates of the adjacent vertex B of the vertex C.

That is, the width is:

this can deduce that the target parking space area is 10 long and 5 wide.

Step C2: and the electronic equipment performs scaling processing on the determined size of the target parking space area according to a preset scaling ratio, and adjusts the size of the parking space live-action image according to the processed size of the target parking space area.

In implementation, the present application configures scaling. The scaling ratio may be 1 (i.e., maintain the original appearance without scaling) or may be a value other than 1 (i.e., indicate scaling or zooming).

After the electronic device calculates the length and width of the target parking space area, the electronic device can perform scaling processing on the determined length and width according to a preset scaling ratio.

When the scaling processing is performed, the electronic device may multiply the calculated length or width of the target parking space region by the scaling ratio column to obtain the scaled length or width of the target parking space region.

For example, when the scaling ratio is 1, the length or width of the target parking space area after scaling processing is consistent with that before scaling.

And when the scaling is smaller than 1, reducing the length or the width of the determined target parking space area.

And when the scaling is larger than 1, amplifying the determined length or width of the target parking space area.

In the embodiment of the application, the electronic device may adjust the parking space live-action image according to the zoomed length and width of the target parking space region, so that the length and width of the parking space live-action image are consistent with the length and width of the target parking space region.

For example, in order to display the parking space real image and the parking space identifier at the same time, the preset scaling ratio may be 1/2, and after determining the length and the width of the target parking space region, the electronic device may multiply the determined length of the target parking space region by the preset scaling ratio, where the scaled length of the target parking space region is 5 and the scaled width of the target parking space region is still 5.

Then, the electronic device may adjust the length of the parking space live-action image to 5 and the width to 5. Such adjustment can make the regional half of parking stall be used for showing the parking stall outdoor scene image of parking stall, and the other half is used for showing the parking stall sign.

2) Adjustment of the angle of rotation.

During implementation, the electronic device may determine a rotation angle of the parking space real image, and rotate the parking space real image according to the rotation angle, so that an appointed side of the rotated parking space real image coincides with an appointed side of the target parking space area

The designated edge of the parking space live-action image corresponds to the designated edge of the target parking space region, for example, the designated edge of the parking space live-action image is the bottom edge, and the designated edge of the target parking space region is also the bottom edge.

When the rotation angle of the parking space live-action image is determined, the electronic equipment can determine the included angle between the designated side of the target parking space region and the designated direction, and determine the determined included angle as the rotation angle of the parking space live-action image.

The designated side may be any side of the target parking space region, and the designated direction may be a horizontal direction or a vertical direction, or other directions, where the designated side and the designated direction are only exemplarily described and are not specifically limited.

The rotation angle of the parking space live view image will be described in detail below, taking the designated side as the top side of the target parking space area and the designated direction as the horizontal direction as an example.

For example, the example of fig. 4 is still taken as an example.

As shown in fig. 4, the angle (β) between the top edge (i.e. CD) of the target parking space region and the horizontal direction is the rotation angle of the parking space live-action image.

How to determine the rotation angle of the parking space live-action image is described below

Specifically, the rotation angle can be obtained by the arc tangent between two vertex coordinates of the top edge of the target parking space region, and the radian is arctan (|10-4|/|8-0 |). If the Y coordinates of all points on the top edge sequentially increase after traversing from left to right of the top edge, the rotation angle is arctan (|10-4|/|8-0 |). If the Y coordinates of all points on the top edge sequentially decrease from left to right according to the top edge, the rotation angle is 2 pi-arctan (|10-4|/|8-0 |).

The above is an introduction to the preprocessing method of the parking space live-action image.

In addition, in the embodiment of the application, when it is monitored that the hierarchy of the parking area map is changed from the designated hierarchy to the non-designated hierarchy, the electronic device removes the parking space live-action image of the visual field of the parking area map.

For example, when the user narrows down the parking area map from 22 or 23 layers to a level lower than 22 layers, the electronic device may clear the parking space live-action image in the visible area of the parking area map, so that the visible area only displays the occupied parking space in a color block manner.

Because the parking space live-action image is only supported to be clearly displayed in the display scale of the designated level, in order to clearly display the parking space live-action image, when the electronic device detects that the map layer of the parking area map is updated to 22 layers or 23 layers, the electronic device renders the parking space live-action image corresponding to the parking space in the visible area of the cached parking area map to the corresponding parking space area.

When the electronic device detects that the map layer of the parking area map is updated from 22 layers or 23 layers to non-22 layers or non-23 layers, the level cannot meet the requirement of clear display of the parking space live-action image, and in order to enable the rendered parking space live-action image not to occupy a memory, the electronic device can delete the rendered parking space live-action image in the parking area map visual field. In addition, if the sub-device still displays the parking space live-action image when detecting that the map layer of the parking area map is updated from 22 layers or 23 layers to non-22 layers or non-23 layers, the parking area map will display the dense and rough unclear parking space live-action image, and the use experience of the user is reduced.

In addition, when the electronic device detects that the parking area map is updated from one designated level to another designated level, the electronic device may adjust the display scale of the rendered parking space live-action image and re-render the adjusted parking space live-action image. For example, when the electronic device detects that the parking area map is updated from 23 layers to 22 layers, the electronic device may reduce the rendered parking space real image to the display scale supported by 22 layers, and then re-render the adjusted parking space real image.

2. In the second case: the parking space included in the visible area of the parking area map currently displayed by the electronic device is rendered with the parking space real image, and the parking space real image in the parking area is continuously updated, so that the rendered parking space real image needs to be updated by the electronic device, so that the rendered parking space real image is consistent with the real parking space real image.

2.1), in the second case, the above-mentioned "step 201: and determining a target parking space area of the target parking space to be updated from the visual area of the currently displayed parking area map.

Step 2.1) is explained below by steps D1 to D2.

Step D1: and the electronic equipment acquires and caches the latest parking space real image of at least one parking space with the parking space real image changed in the target time period.

The target time period may be one time period or a plurality of time periods.

When the target period is a plurality of periods, the target period may be spaced by equal time update cycles. For example, the electronic device may periodically obtain and cache the latest parking space real image of at least one parking space in which the parking space real image changes in the update period. For example, the update period is 5 minutes, and the electronic device may obtain and cache the latest parking space real-scene image of at least one parking space in which the parking space real-scene image changes in the current 5 minutes every 5 minutes.

Of course, the time periods may also be a plurality of time periods with different time intervals, for example, the electronic device may obtain and cache the latest parking space real image of at least one parking space in which the parking space real image changes in the first 5 minutes. And then acquiring and caching the latest parking space real image of at least one parking space with the changed parking space real image in 4 minutes after 4 minutes (namely 9 minutes) from the beginning of the 5 th minute.

The target time period is only exemplified and not particularly limited.

In practical applications, in order to save resources of the electronic device and reduce complexity of programming, the electronic device usually periodically obtains and caches the latest parking space real image of at least one parking space where the parking space real image changes in the update period.

Step D2: and if the parking space corresponding to the obtained any latest parking space real image is the parking space contained in the visual area and the current level of the parking area map is the designated level, the electronic equipment determines the parking space corresponding to the any parking space real image as the target parking space to be updated.

The steps D1 and D2 are explained in detail below.

The implementation of step D1 is as follows:

after implementing "step D1: when the electronic device obtains and caches the latest parking space live-action image of at least one parking space in which the parking space live-action image changes within the target time period, the electronic device may send a query request for each parking space of the parking area map to the server.

After receiving the query request, the server determines at least one parking space in which the parking space real view image changes within the target time period, and sends an acquisition address (such as a link) of the latest parking space real view image corresponding to the at least one parking space to the electronic device. And the electronic equipment acquires and caches the latest parking space live-action image of at least one parking space with the changed parking space live-action image in the target time period based on the acquired address.

Specifically, for each parking space, the electronic device may send an inquiry request for the parking space to the service, where the inquiry request carries the parking space identifier.

After receiving the query request, the server may search whether the latest carport real-scene image exists in a time period formed by the time when the carport real-scene image was returned to the electronic device last time and the current time (for example, the server may read the current time of the device).

The inquiry request can also carry the current time, and the server can search whether the latest parking space live-action image exists in the time period formed by the last time of returning the parking space live-action image to the electronic equipment and the current time carried in the inquiry request.

If the latest parking space real image exists, the parking space corresponding to the latest parking space real image is determined as the parking space with the changed parking space real image. The server may return to the electronic device an acquisition address (e.g., a link URL) for acquiring the latest image of the parking space scene of the parking space. And the electronic equipment acquires the latest parking space live-action image of the target parking space from the server based on the acquisition address.

Further, the electronic device may receive multiple acquisition links. In order to improve the efficiency of acquiring the latest real-scene images, the electronic device may concurrently acquire the corresponding latest parking-space real-scene images through a specified number of acquisition addresses.

The benefit of specifying the above specified number (alternatively referred to as the concurrency number) is that: the situation that the electronic equipment cannot display the parking space live-action image due to the fact that the request is intercepted overtime due to the fact that the number of concurrent requests for obtaining the image is increased is prevented.

Implementation manner of step D2:

after implementing "step D2: if the parking space corresponding to the obtained any latest parking space real image is the parking space included in the visible area and the current hierarchy of the parking area map is the designated hierarchy, and the electronic device determines the parking space corresponding to the any parking space real image as the target parking space needed to be updated, for each latest parking space real image, if the parking space corresponding to the parking space real image is detected as the parking space included in the visible area of the parking area map and the current hierarchy of the current parking area map is the designated hierarchy, the electronic device may determine the parking space corresponding to the latest parking space real image as the target parking space. And if the parking space corresponding to the parking space live-action image is detected not to be the parking space contained in the visible field of the parking area map or the current level of the current parking area map is not the designated level, rendering is not performed, and only caching is performed.

The above is an implementation of step 201.

The implementation of step 202 in the second case is the same as that of step 202 in the first case, and is not described here again.

In addition, in the embodiment of the application, after the parking space live-action image is rendered, the electronic device further provides a function of zooming the details of the parking space live-action image.

Specifically, when a user clicks a certain parking space live-action image in the visible area, the electronic device may monitor a trigger operation for the parking space live-action image displayed in the current visible area. When the display triggering operation aiming at the parking space real-scene image displayed in the current visual area is monitored, the electronic equipment can display the parking space real-scene image in a display mode different from the display mode of the parking space real-scene image displayed in the current visual area.

Specifically, the user may click on a display option of a certain parking space on the parking area map and input a corresponding display scale (e.g., input the display scale through a wheel of a mouse). When the user performs this operation, the electronic device may detect a display trigger operation of the parking space live-action image displayed in the visible area of the parking area map. At this time, the electronic device may establish a floating display window in the visible area, and display the parking space live-action image in the floating display window according to the display scale indicated by the display triggering operation.

In addition, the electronic device also provides preview and playback functionality.

1) Preview function

For example, a "preview option" is also deployed on the parking area map, and the user can click on the "preview option" and select any parking space to be previewed. For example, if the user selects any parking space, a "preview option" and/or a "playback option" may appear on the interface for the user to select. For example, the user selects an arbitrary parking space, and the selecting operation for the arbitrary parking space is equivalent to triggering a video preview operation for the arbitrary parking space. When the user performs the operation, the electronic device may monitor a video preview trigger operation for any parking spot on the parking area map. At this time, the electronic device acquires the video of the arbitrary parking space from the server, and displays the video of the arbitrary parking space. In other words, the electronic device may obtain the video of the arbitrary parking space, which is collected by the monitoring device in real time, from the server, and display the obtained video to the user.

2) Playback function

A 'playback option' is also deployed on the parking area map, and a user can click the 'playback option' and select any parking place needing playback. For example, if the user selects any parking space, a "preview option" and/or a "playback option" may appear on the interface for the user to select. For example, the user selects any parking space, and the selection action of any parking space is equivalent to triggering the video playback operation of any parking space. When the user performs the operation, the electronic device may monitor a video playback trigger operation for any parking spot on the parking area map. At this time, the electronic device acquires the video of the arbitrary parking space acquired within the playback time period indicated by the playback trigger event from the server, and displays the acquired video of the arbitrary parking space.

The playback time period can be input by a user, and the electronic device can play back the video of any parking space in the playback time period input by the user.

Of course, the playback time period may also be preset by the electronic device for selection by the user. The electronic equipment can play back the parking space videos of any parking space in the playback time period selected by the user.

Because each parking space live-action image is periodically updated, in order to enable a user to see the parking space live-action images of the parking spaces in all the time, the electronic device can determine the parking space live-action images of the parking spaces in all the time by setting the playback time period. For example, the electronic device may set the playback time period according to the update cycle of the parking space live-action image. For example, setting the playback period includes an update cycle.

For example, it is assumed that the parking space live-action image is refreshed every 10 seconds, so that the user can only see the parking space live-action images of the first second and the 11 th second, but cannot see the parking space live-action images of 2 to 10 seconds. The electronic device can set the playback time period to 1-11 seconds, so that the user can acquire the parking space live-action image of each second of 1-11 seconds through the playback function.

The playback time period may also be a playback time period preset by the electronic device and based on a preset cycle duration from the current time point or the time point when the real-scene image of the current parking space is captured. The preset period duration may be a preset period duration used for determining whether the parking space live-action image changes within the preset period duration.

The playback time period may also be a plurality of time periods preset by the electronic device for the user to select, where the duration of each time period is a preset period duration, and the end-to-end time points of every two time periods are connected with each other, that is, the end time of the first time period is equal to the start time of the second time period, the second time period is the next time period of the first time period, and the last time point of each time period is the current time point or the time point at which the live-view image of the current parking space is captured.

It can be known from the above description that the parking space displayed by the electronic device is no longer the information about the occupied parking space alone, but is the current parking space live-action image of the parking space, and the parking space manager can acquire various parking space information (for example, the license plate number of the parking space occupied, whether there is a parking break, etc.) from the live-action image, so that the management of the parking space is greatly facilitated.

In addition, the electronic device can periodically acquire the latest parking space live-action image of the parking space with the changed parking space live-action image from the server and cache the latest parking space live-action image, so that the cached parking space live-action image of each parking space in the electronic device is consistent with the real parking space situation.

In addition, after the electronic device acquires the latest parking space live-action image, if the parking space corresponding to the latest parking space live-action image is in the visual area and the current level of the parking area map is the designated level, the acquired latest target parking space live-action image is rendered to the parking space area of the target parking space, so that the visual area can display the latest parking space live-action image.
