Background

With the popularization of automobiles and the development of camera technologies, in order to improve the safety of the running process of a vehicle, a plurality of vehicle owners can choose to install a vehicle event data recorder in the vehicle.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the description herein are intended to be within the scope of the present disclosure.

In order to solve the problems in the related art, embodiments of the present application provide a video loop storage method. The method can be applied to electronic equipment, such as vehicle-mounted terminals of automobile data recorders and the like. The specific storage location of the video may be a memory built in the electronic device itself, or may be an external memory connected to the electronic device, such as a TF card, a Universal Serial Bus (USB) disk or a USB disk, a hard disk, or the like, or may be a storage server. Here, the electronic device and the video storage location are not particularly limited.

As shown in fig. 1, fig. 1 is a first flowchart of a video loop storage method according to an embodiment of the present application. The method comprises the following steps.

And step S101, acquiring a video segment to be stored of the target vehicle.

Step S102, if the current residual storage space is less than or equal to a preset threshold value, acquiring preset characteristic information of a stored historical video segment; the type of the preset characteristic information comprises driver information and/or vehicle running information.

Step S103, determining the video segment to be deleted based on the preset characteristic information of the historical video segment.

And step S104, deleting the video segment to be deleted from the stored historical video segment, and storing the video segment to be stored.

By the method shown in fig. 1, after the video segment to be stored of the target vehicle is acquired, if the electronic device determines that the current remaining storage space is less than or equal to the preset threshold, it is determined that the storage space is not enough to continue storing the video, and the video segment to be deleted is determined from the stored historical video segments based on the preset characteristic information of the stored historical video segments. And the electronic equipment deletes the determined video segment to be deleted to obtain an available storage space and stores the video segment to be stored.

Compared with the prior art in which the history video segment with the earliest storage time is directly deleted, in the embodiment of the present application, since there is a certain difference in the preset characteristic information of each history video segment stored in the electronic device, that is, there is a certain difference in the driver information, the vehicle driving information, and the like corresponding to each history video segment, therefore, when the acquired video segments to be stored are stored each time, the video segments to be deleted determined according to the preset characteristic information of the stored historical video segments are different, so that each stored historical video segment can be determined as the video segment to be deleted, so that the determined video segment to be deleted is no longer limited to the history video segment with the earliest storage time, namely, the method is not limited to only performing the cyclic coverage of the video according to the time dimension, and the selectivity of the video segment deleted in the cyclic storage process of the video is improved.

The following examples are given to illustrate the examples of the present application.

For the above step S101, a video segment to be stored of the target vehicle is acquired.

In this step, a video shooting device, such as a camera in a drive recorder, is mounted on the target vehicle. After the target vehicle is started, the video shooting device can shoot the peripheral scenes of the target vehicle in real time to obtain a plurality of video segments to be stored corresponding to the target vehicle. For example, the video shooting device can shoot a scene right in front of or behind a target vehicle in real time to obtain a plurality of video segments to be stored. At this time, the electronic device may cyclically store the video segments to be stored, which are acquired in real time.

The number of the video segments to be stored can be one or more. In this embodiment, after the target vehicle is started, the video shooting device may divide a complete video acquired in real time for a preset duration into a plurality of video segments, and send the video segments to the electronic device as the plurality of video segments to be stored; the video shooting equipment can also directly take a complete video with a preset time length collected in real time as a video segment and send the video segment to the electronic equipment for storage. The capture duration of each video segment can be determined according to actual conditions.

In an optional embodiment, the video segment to be stored may be obtained by dividing the acquired video according to the duration of the video. For example, the video shooting device may divide the shot video by taking 3 minutes as a preset time length to obtain a plurality of video segments to be stored, of which the video time length is 3 minutes. The preset duration can be set according to the requirements of users or actual conditions. Here, the preset time period is not particularly limited.

In another optional embodiment, the video segment to be stored may be obtained by dividing the collected video segments according to the data amount of the video.

In the embodiment of the present application, a manner of dividing the video segment to be stored is not particularly limited.

In an optional embodiment, in order to ensure the ordering of video storage, after the video segments to be stored are captured by the video capturing device, the electronic device may sequentially store each video segment to be stored according to the sequence of the time corresponding to each video segment to be stored.

In an alternative embodiment, the electronic device and the video capture device may be disposed on the same electronic device. For example, the video shooting device is a camera of a vehicle event data recorder, and the electronic device is the vehicle event data recorder. At this time, the video segments captured by the video capturing device can be circularly stored in the memory of the tachograph or the TF card.

In another alternative embodiment, the electronic device and the video capturing device may be two different electronic devices. For example, the video shooting device is a camera disposed on a vehicle body, and the electronic device is a vehicle event data recorder.

In the embodiment of the present application, the electronic apparatus and the video capturing apparatus are not particularly limited.

For the step S102, that is, if the current remaining storage space is less than or equal to the preset threshold, acquiring preset feature information of the stored history video segment; the type of the preset characteristic information comprises driver information and/or vehicle running information.

In this embodiment of the present application, according to a difference in video storage locations, the current remaining storage space may include remaining storage spaces corresponding to different storage locations. For example, the electronic device may determine that the remaining storage space of a memory built in the electronic device is less than or equal to a preset threshold, may determine that the remaining storage space of an external memory (e.g., a TF card, a U-disk, a hard disk, etc.) connected in the electronic device is less than or equal to a preset threshold, or may determine that the remaining storage space of a storage server is less than or equal to a preset threshold. The historical video segment is a video segment stored before the current time. The storage manner of the history video segment can refer to the related explanation of the storage manner of the video segment to be stored, and is not specifically described here.

After the electronic device obtains the video segment to be stored, the remaining storage space at the current time (i.e., the current remaining storage space) can be calculated according to the data size of the historical video segment and the total video storage space. The electronic device compares the calculated current remaining storage space with a preset threshold value, thereby determining whether the current remaining storage space is less than or equal to the preset threshold value.

When the current remaining storage space of the electronic device is less than or equal to the preset threshold, the available storage space is not enough, and the electronic device can determine that the historical video segment needs to be deleted. At this time, the electronic device may acquire preset feature information of the history video segment. The type of the preset characteristic information may include driver information and/or vehicle travel information.

In an optional embodiment, the vehicle driving information includes at least one of: travel time, geographic location, road type, travel speed, road condition information, and the like. Here, the vehicle travel information is not particularly limited.

In the embodiment of the present application, for each feature type, a plurality of feature information may be included under the feature type. Taking the characteristic type as the driver information as an example, the characteristic information in the driver information type of the video segment may include the owner himself (hereinafter, simply referred to as the owner) and the non-owner himself (hereinafter, simply referred to as another person), and may further include personal information such as the age and occupation of the driver. Alternatively, this information may be obtained by driver representation. For the feature information included in each of the above feature types, reference is made to the following description, which is not specifically described herein.

In an optional embodiment, when the electronic device determines that the current remaining storage space is greater than the preset threshold, the available storage space is sufficient, and at this time, the electronic device may directly perform a storage operation on the video segment to be stored.

In this embodiment of the application, the preset threshold may be set according to the size of each video segment to be stored, or may be preset according to a user requirement. Here, the preset threshold is not particularly limited.

In the present embodiment, the driver information may include any information related to the current driver of the vehicle; the vehicle running information may include any information related to the current running condition of the vehicle, and may include, for example, running state information of the vehicle itself and information related to the running environment of the vehicle. In practical application, the content of the characteristic information for marking and distinguishing the video segments can be set reasonably.

In step S103, a video segment to be deleted is determined based on the preset characteristic information of the history video segment.

In this step, the electronic device may select one or more history video segments from the plurality of history video segments as the video segments to be deleted according to the preset feature information corresponding to each history video segment. For the determination of the video segment to be deleted, reference is made to the following description, which is not specifically described here. Here, the number of the determined video pieces to be deleted is not particularly limited. And performing associated storage on the preset characteristic information corresponding to the historical video segment in the process of storing the historical video segment. Namely, after the electronic device obtains the video segment to be stored, the electronic device analyzes and stores the characteristic information corresponding to the video segment in a correlated manner.

In step S104, the to-be-deleted video segment is deleted from the stored history video segments, and the to-be-stored video segment is stored.

In this step, after determining the video segment to be deleted, the electronic device deletes the video segment to be deleted to obtain an available storage space, and stores the video segment to be stored in the storage space.

In an optional embodiment, the electronic device is preset with a feature priority, where the feature priority may include a priority corresponding to a plurality of feature types and/or a priority of feature information in each feature type. The feature priority may be a default priority preset in the device or a priority set by a user in a self-defined manner.

In an optional embodiment, the present application further provides a video loop storage method. As shown in fig. 2, fig. 2 is a second flowchart of a video loop storage method according to an embodiment of the present application. The method comprises the following steps.

In step S201, a video segment to be stored of the target vehicle is acquired.

Step S202, if the current residual storage space is less than or equal to a preset threshold value, preset characteristic information of the stored historical video segment is acquired; the type of the preset characteristic information comprises driver information and/or vehicle running information.

The above steps S201 to S202 are the same as the above steps S101 to S102.

Step S203, according to the preset feature priority, determining the video segment to be deleted based on the preset feature information of the historical video segment.

In this step, the electronic device may determine, according to the preset feature information of the historical video segment and the preset feature priority, the historical video segment corresponding to the preset feature information with a higher priority as the video segment to be deleted. For example, a video segment with a higher priority of a feature type of preset feature information in stored historical video segments and a higher priority of feature information in the feature type can be determined as a video segment to be deleted. Specifically, for example, if the type priority corresponding to the travel time is higher than the type priority corresponding to the driver information, and the priority of the travel time being the early peak time is higher than the priority of the travel time being the non-peak time, the history video segment with the preset feature information being the early peak may be determined as the video segment to be deleted.

In the embodiment of the present application, the preset feature priority is used to indicate the deletion priority of the video segment. That is, the higher the feature priority corresponding to the preset feature information of the history video segment is, the higher the probability that the history video segment is determined as the video segment to be deleted is; the lower the feature priority corresponding to the preset feature information of the historical video segment is, the lower the probability that the historical video segment is determined to be the video segment to be deleted is.

In step S204, the video segment to be deleted is deleted from the stored history video segments, and the video segment to be stored is stored.

Step S204 is the same as step S104.

In an optional embodiment, the present application further provides a video loop storage method. As shown in fig. 3, fig. 3 is a third flowchart of a video loop storage method according to an embodiment of the present application. The method comprises the following steps.

In step S301, a video segment to be stored of the target vehicle is acquired.

Step S302, if the current residual storage space is less than or equal to a preset threshold, acquiring preset characteristic information of a stored historical video segment; the type of the preset characteristic information comprises driver information and/or vehicle running information.

The above steps S301 to S302 are the same as the above steps S101 to S102.

Step S303, according to the first setting operation of the user on the feature type display interface, determining the priority of the feature type set by the user.

In this step, the user may trigger an operation of setting the priority of the feature type, that is, trigger a first setting operation, on the feature type presentation interface provided by the electronic device. At this time, the electronic device determines the priority of the feature type set by the user according to the first setting operation.

For example, the user may set the priority of the driver information to the highest priority in the above-described feature type presentation interface. At this time, the electronic device determines that the priority of the driver information is higher than the priority of the vehicle travel information according to the first setting operation by the user.

In the embodiment of the present application, the priorities corresponding to different feature types may be the same or different. Here, the priority of each feature type is not particularly limited.

In the embodiment shown in fig. 3, the above step S303 is performed after step S302. In addition, the step S303 may be executed before, during or after the step S301 is executed, or may be executed before or during the step S302 is executed. Here, the execution sequence of step S303 and step S301 or step S302 is not particularly limited.

Step S304, determining the priority of the feature information under each feature type according to the second setting operation of the feature information display interface of the user under each feature type.

In this step, the user may trigger a setting operation of the priority of the feature information, that is, trigger a second setting operation, in the feature information presentation interface of each feature type provided by the electronic device. At this time, the electronic apparatus may determine the priority of the feature information for each feature type set by the user according to the second setting operation.

The characteristic type display interface and the characteristic information display interface can support touch operation of a user. Here, the triggering manner of the first setting operation in the feature type display interface and the triggering manner of the second setting operation in the feature information display interface are not particularly limited.

The first setting operation and the second setting operation may be a setting operation performed when the user uses the electronic device for the first time, that is, an initial setting operation, or may be an adjustment operation of a priority during use of the electronic device, that is, an adjustment setting operation.

In the embodiment of the present application, the step S303 may be executed before/after the step S304, and the execution sequence of the step S303 and the step S304 is not particularly limited.

Step S305, determining the video segment to be deleted based on the preset characteristic information of the historical video segment according to the preset characteristic priority.

Step S306, deleting the video segment to be deleted from the stored historical video segment, and storing the video segment to be stored.

The above-described step S305 to step S306 are the same as the above-described step S103 to step S104.

For the sake of understanding, the above steps S304-S305 are exemplarily described with reference to fig. 4-a to 4-g, and should not be construed as specifically limiting the embodiments of the present application. The specific layout of different display interfaces and the skip display among different display interfaces can be adaptively adjusted and set.

The electronic device may provide the user with a feature type presentation interface as shown in fig. 4-a. The user can select the feature type corresponding to the feature information to be subjected to priority setting in the selection area 10 of the feature type display interface by touching the selection button 12 and the selection button 13. After determining the feature type requiring priority setting, the user enters a corresponding feature information display interface by touching the determination button 11. That is, the user can select to enter the feature information presentation interface corresponding to the feature type shown in fig. 4-b, such as the driver information 14, the travel time 15, the geographic position 16, the road type 17 or the travel speed 18, by touching the selection button 12, the selection button 13 and the determination button 11.

When the user selects to enter the feature information presentation interface corresponding to the driver information in the feature type presentation interface shown in fig. 4-a, the interface shown in fig. 4-a may be switched to the feature information presentation interface corresponding to the driver information 14 shown in fig. 4-b, such as the interface 140 shown in fig. 4-c. The characteristic information under the characteristic type being driver information may be classified into the self and the other person. When the characteristic information is the owner, indicating that a driver of the vehicle is the owner; and when the characteristic information is other people, indicating that the driver of the vehicle is other people except the owner, namely the owner is not the owner.

For example, in the interface 140 shown in fig. 4-c, when the user selects the button 144 before touching the principal 141, the feature information-principal is set as the feature information of higher priority in the driver information type. At this time, the priority level corresponding to the characteristic information-the person himself is higher than the priority level corresponding to the characteristic information-the other person. That is, the electronic device preferentially determines the history video segment with the characteristic information of the driver as the user as the video segment to be deleted.

When the user selects the button 143 before touching the other person 142, the feature information-other person is set as the feature information of which priority is higher in the driver information type. At this time, the priority corresponding to the characteristic information-the person himself is lower than the priority corresponding to the characteristic information-the other person. That is, the electronic device preferentially determines the history video segment with the characteristic information of others in the driver information type as the video segment to be deleted.

When the user selects the feature information presentation interface corresponding to the travel time from the feature type presentation interface shown in fig. 4-a, the interface shown in fig. 4-a may be switched to the feature information presentation interface corresponding to the travel time 15 shown in fig. 4-b, such as the interface 150 shown in fig. 4-d. The characteristic information at the characteristic type of travel time may be divided into a peak period and an off-peak period. Wherein, when the characteristic information is a peak period, indicating that the running time period of the vehicle is in a pre-divided peak period of vehicle running; and indicating that the travel time period of the vehicle is within the pre-divided off-peak period of vehicle travel when the characteristic information is the off-peak period.

Illustratively, in the interface 150 shown in fig. 4-d, when the user selects the button 154 before the touch peak period 141, the characteristic information-peak period is set as the higher priority information in the travel time type. At this time, the priority corresponding to the feature information-peak period is higher than the priority corresponding to the feature information-non-peak period. That is, the electronic device preferentially determines the history video segment with the characteristic information of the peak period in the travel time type as the video segment to be deleted.

When the user selects the button 153 before the off-peak period 152, at this time, the feature information-off-peak period is set as the feature information of higher priority in the travel time type. At this time, the priority corresponding to the characteristic information-peak period is lower than the priority corresponding to the characteristic information-non-peak period. That is, the electronic device preferentially determines the history video segment whose characteristic information is the off-peak period in the travel time type as the video segment to be deleted.

In the embodiment of the present application, the peak period and the off-peak period may be set according to the user requirement. For example, 8:00-9:30, and 17:30-19:00 of the day may be set as peak periods, and times other than peak periods may be set as off-peak periods. Here, the setting of the peak period and the non-peak period is not particularly limited.

In the above embodiment, the description is given by taking as an example only the case where the characteristic information at the travel time is divided into the peak period and the non-peak period. In addition, the characteristic information of the travel time may be classified into: in the morning (e.g., 0:00-5:59), during the day (e.g., 6:00-17:59), and in the evening (e.g., 18:00-23: 59). Here, the travel time characteristic information is not particularly limited.

When the user selects to enter the feature information presentation interface corresponding to the geographic location in the feature type presentation interface shown in fig. 4-a, the interface shown in fig. 4-a may be switched to the feature information presentation interface corresponding to the geographic location 16 shown in fig. 4-b, such as the interface 160 shown in fig. 4-e. The feature information in which the feature type is the geographic location may include a preset city and a non-preset city, or a preset geographic area and a non-preset geographic area, such as an downtown area and a non-downtown area. When the characteristic information is a preset city (or a preset geographical area), indicating that the geographical position where the vehicle runs is within the preset city (or the preset geographical area); and when the characteristic information is a non-preset city (or a non-preset geographical area), indicating that the geographical position of the vehicle is in the non-preset city (or the non-preset geographical area).

The preset city (or the preset geographical area) may be a city (or an area) designated by the user, or may be a city (or a geographical area) where the vehicle is located. The number of the preset cities or the preset geographic areas may be 1 or more, and the embodiment of the present application is not particularly limited.

For example, in the interface 160 shown in fig. 4-e, when the user selects the button 164 before touching the preset city 161, the feature information-preset city is set as the feature information of higher priority in the geographical location type. At this time, the priority corresponding to the characteristic information-preset city is higher than the priority corresponding to the characteristic information-non-preset city. That is, the electronic device preferentially determines the historical video segment with the characteristic information of the preset city in the geographic location type as the video segment to be deleted.

When the user selects the button 163 in front of the non-preset city 162, the feature information-non-preset city is set as feature information of higher priority in the geographical location. At this time, the priority corresponding to the characteristic information-preset city is lower than the priority corresponding to the characteristic information-non-preset city. That is, the electronic device preferentially determines the historical video segment with the characteristic information of the non-preset city in the geographic location type as the video segment to be deleted.

When the user selects to enter the feature information display interface corresponding to the road type in the feature type display interface shown in fig. 4-a, the interface shown in fig. 4-a may be switched to the feature information display interface corresponding to the road type 17 shown in fig. 4-b, that is, the interface 170 shown in fig. 4-f. The characteristic information under the characteristic type being the road type may include an urban road, an expressway, and a rural road. When the characteristic information is an urban road, indicating that the road on which the vehicle runs is the urban road; when the characteristic information is an expressway, indicating that the road on which the vehicle runs is the expressway; and indicating that the road on which the vehicle runs is the rural road when the characteristic information is the rural road.

For example, in the interface 170 shown in fig. 4-f, when the user selects the button 176 before touching the urban road 171, the feature information — the urban road is set as the feature information of higher priority under the road type. At this time, the priority level corresponding to the characteristic information-urban road is higher than the priority level corresponding to the characteristic information-expressway and rural road. That is, the electronic device preferentially determines the history video segment with the characteristic information of the urban road under the road type as the video segment to be deleted.

When the user selects the button 175 before touching the expressway 172, the feature information-expressway is set as the feature information of higher priority under the road type. At this time, the priority level corresponding to the characteristic information-expressway is higher than the priority level corresponding to the characteristic information-urban road and rural road. That is, the electronic device preferentially determines the history video segment whose characteristic information is the expressway under the road type as the video segment to be deleted.

When the user selects the button 174 before touching the country road 173, the feature information — the country road is set as the feature information of which priority is higher under the road type. At this time, the priority level corresponding to the characteristic information-country road is higher than the priority level corresponding to the characteristic information-city road and expressway. That is, the electronic device preferentially determines the history video segment with the characteristic information of the country road under the road type as the video segment to be deleted.

In the interface 170 shown in fig. 4-f, the user can select a plurality of feature information as the specified feature information under the road type. As shown in fig. 4-f, the characteristic information-expressway and the characteristic information-rural road are set as the characteristic information of higher priority under the road type. That is, the electronic device preferentially determines the history video segments with the characteristic information of the country road and the expressway under the road type as the video segments to be deleted.

In the embodiment of the present application, the characteristic information of the road type may be divided in other ways besides being divided into an urban road, an expressway and a rural road.

For example, the characteristic information under the above-described road types may be further classified into an expressway and a non-expressway, wherein the expressway may be further classified into a national road and a provincial road. Here, the feature information in the road type is not particularly limited.

When the user selects to enter the feature information display interface corresponding to the driving speed in the feature type display interface shown in fig. 4-a, the interface shown in fig. 4-a is switched to the feature information display interface corresponding to the driving speed 18 in fig. 4-b, that is, the interface 180 shown in fig. 4-g. The characteristic information at the characteristic type of the running speed may include a low speed, a medium speed, and a high speed. When the characteristic information is low speed, indicating that the running speed of the vehicle is in a preset low speed interval; when the characteristic information is a medium speed, it means that the vehicle running speed is within a preset medium speed interval. And when the characteristic information is high speed, indicating that the running speed of the vehicle is in a preset high-speed interval.

The low-speed section, the medium-speed section and the high-speed section can be divided according to the requirements of users. For example, the low speed range may be 10km/h (kilometers per hour) to 60km/h, the medium speed range may be 60km/h to 90km/h, and the high speed range may be 90km/h or more. Here, the division into each speed interval is not particularly limited.

For example, in the interface 180 shown in fig. 4-g, when the user selects the button 186 before the touch of the low speed 181, the feature information-low speed is set as the feature information of higher priority at the traveling speed. At this time, the priority corresponding to the feature information-low speed is higher than the priority corresponding to the feature information-medium speed and high speed. That is, the electronic device preferentially determines the history video segment whose characteristic information is low speed in the travel speed type as the video segment to be deleted.

When the user selects the button 185 before the medium speed 182, the feature information-medium speed is set as the feature information of which the priority is higher in the travel speed type. At this time, the priority corresponding to the feature information-medium speed is higher than the priority corresponding to the feature information-low speed and high speed. That is, the electronic apparatus preferentially determines the history video segment whose characteristic information is a medium speed in the travel speed type as the video segment to be deleted.

When the user selects the button 184 before the touch high speed 183, the characteristic information-high speed is set as the higher priority characteristic information in the travel speed type. At this time, the priority corresponding to the feature information-high speed is higher than the priority corresponding to the feature information-low speed and medium speed. That is, the electronic device determines the history video segment whose characteristic information is high speed in the travel speed type as the video segment to be deleted with priority.

In the interface 180 shown in fig. 4-g, the user can select a plurality of pieces of feature information as feature information having higher priority at the traveling speed. As shown in fig. 4-g, the feature information-medium speed and the feature information high speed are both set as feature information of higher priority in the traveling speed.

In the embodiment of the present application, for each feature type, there may be a corresponding priority for each feature information under the feature type. For ease of understanding, the above-described example of FIG. 4-g is illustrated. Since the feature information-medium speed and high speed are set as the feature information having higher priority, the priority corresponding to the feature information-medium speed and feature information high speed is higher than the priority corresponding to the feature information-low speed, and the priority corresponding to the feature information-medium speed may be the same as the priority corresponding to the feature information-high speed. Here, the priority corresponding to the feature information in each of the above feature types is not particularly limited.

In the above-described embodiments shown in fig. 4-a to 4-g, only the characteristic types are described as examples of the driver information, the travel time, the geographical position, the road type, and the travel speed. When the vehicle driving information further includes road section information and road condition information, the priority setting manner of the characteristic information under the road section information and the road condition information may refer to the priority setting manner of the characteristic information under the driver information, the driving time, the geographic position, the road type, and the driving speed, which is not specifically described herein.

In the embodiment of the present application, when the feature type is the link information, the feature information in the link information may be divided into a monitored link and an unmonitored link. When the characteristic type is the traffic information, the characteristic information under the traffic information can be divided into a special section (e.g., a section with a lot of accidents, a section with sharp turns, a section with congestion, etc.) and a non-special section. Here, the feature types are not particularly limited to the feature information under the link information and the traffic information.

In an optional embodiment, if the preset feature information of the history video segment corresponds to a plurality of feature types, when the electronic device determines the video segment to be deleted according to the preset feature priority based on the preset feature information of the history video segment, it is necessary to comprehensively consider the priority of the history video segment corresponding to each feature type and the priority of the feature information corresponding to each feature type.

For ease of understanding, the description will be made taking the video segment 1-the video segment 4 as an example. The characteristic information of the video segment 1 to the video segment 4 under the driver information and the travel time are shown in table 1.

TABLE 1

Video segment	Driver information	Travel time
			Video segment 1	I am	Peak period
Video segment 2	Others are	Off-peak periods
			Video segment 3	I am	Off-peak periods
Video segment 4	Others are	Peak period

It is assumed that the characteristic types are that the priority of the driver information is lower than the priority of the travel time, the priority of the driver is lower than the priority of others under the driver information type, and the priority of the peak time is lower than the priority of the off-peak time under the travel time type. Therefore, according to the priority of the feature type and the priority of the feature information under the feature type, the deletion priorities corresponding to the video segments 1 to 4 are expressed as follows: video segment 2, video segment 4, video segment 3, video segment 1.

When the above-described video segments 1 to 4 are stored in the electronic device, the video segment 2 can be determined as a video segment to be deleted. When the video segment 1, the video segment 3, and the video segment 4 are stored in the electronic device, the video segment 4 can be determined as a video segment to be deleted. When the video segment 1 and the video segment 4 are stored in the electronic device, the video segment 4 can be determined to be a video segment to be deleted.

In an optional embodiment, the present application further provides a video loop storage method. As shown in fig. 5, fig. 5 is a fourth flowchart illustrating a video loop storage method according to an embodiment of the present application. The method comprises the following steps.

In step S501, a video segment to be stored of a target vehicle is acquired.

Step S502, if the current residual storage space is less than or equal to a preset threshold, acquiring preset characteristic information of the stored historical video segment; the type of the preset characteristic information comprises driver information and/or vehicle running information.

The above steps S501 to S502 are the same as the above steps S101 to S102.

Step S503, responding to the selection operation of the user on the characteristic information display interface, determining the preset characteristic information selected by the user, and determining the historical video segment corresponding to the preset characteristic information selected by the user as the video segment to be deleted.

In this step, the user may select the feature information in the feature information display interface, that is, the user triggers the selection operation of the feature information. At this time, the electronic device may determine the feature information selected by the user. The electronic equipment can determine the video segment of the historical video, of which the preset characteristic information comprises the characteristic information selected by the user, as the video segment to be deleted according to the characteristic information selected by the user.

For example, the user selects another person in the feature information display interface corresponding to the driver information, and at this time, the electronic device may acquire a video segment with the feature information preset as another person in the history video segment as the video segment to be deleted.

In an optional embodiment, when the number of history video segments corresponding to the preset feature information selected by the user is multiple, the electronic device may select one history video segment from the history video segments as the video segment to be deleted. For example, the electronic device may arbitrarily select one history video segment as the video segment to be deleted from the history video segments corresponding to the preset feature information selected by the user. For another example, the electronic device may take the history video segment with the earliest storage time as the video segment to be deleted from the history video segments corresponding to the preset feature information selected by the user. For example, the electronic device may take a history video segment with a longer video duration as a video segment to be deleted from history video segments corresponding to preset feature information selected by a user.

In the embodiment of the application, the controllability of the user on the determined video to be deleted is effectively improved by responding to the selection operation of the user on the characteristic information display interface, so that the pertinence of the reserved video segment is improved.

In step S504, the video segment to be deleted is deleted from the stored history video segments, and the video segment to be stored is stored.

Step S504 is the same as step S104.

In an optional embodiment, the present application further provides a video loop storage method. As shown in fig. 6, fig. 6 is a fifth flowchart illustrating a video loop storage method according to an embodiment of the present application. The method comprises the following steps.

Step S601, acquiring a video segment to be stored of the target vehicle.

Step S602, if the current residual storage space is less than or equal to a preset threshold, acquiring preset characteristic information of a stored historical video segment; the type of the preset characteristic information comprises driver information and/or vehicle running information.

The above steps S601 to S602 are the same as the above steps S101 to S102.

Step S603, if the same history video segment includes at least two pieces of preset feature information, respectively determining a video segment duration corresponding to each piece of preset feature information in the history video segment.

In this embodiment of the application, for each historical video, the historical video may include a plurality of preset feature information in one feature type, and may also include preset feature information in a plurality of feature types. When a certain history video segment includes at least two pieces of preset feature information, the electronic device may respectively determine a duration of a video frame occupied by each piece of preset feature information in the history video segment, as a corresponding video segment duration of each piece of preset feature information in the history video segment.

For the sake of understanding, the preset feature information of the history video piece a in the type of the travel speed is described as an example. Assume now that the time duration of the history video segment a is 10 minutes. In the course of 10 minutes of travel of the vehicle corresponding to the history video piece a, the vehicle travels at a low speed for 4 minutes first and then at a medium speed for 6 minutes. Therefore, the preset feature information of the history video piece a at the running speed includes the low speed and the medium speed. In the step S603, the electronic device may determine that the video segment duration corresponding to the preset feature information in the history video segment a being the low speed is 4 minutes, and the video segment duration corresponding to the preset feature information in the history video segment a being the medium speed is 6 minutes.

Step S604, determining target characteristic information of the historical video segment from at least two pieces of preset characteristic information according to the corresponding video segment time length of each piece of preset characteristic information in the historical video segment.

In an optional embodiment, after determining the corresponding video segment time length of each preset feature information of the historical video frame in the historical video segment, the preset feature information with the longest video segment time length corresponding to at least two preset feature information may be determined as the target feature information of the historical video segment.

Still taking the history video segment a as an example, since the preset characteristic information-the video segment duration corresponding to the low speed is smaller than the preset characteristic information-the video segment duration corresponding to the medium speed, the electronic device may determine the preset characteristic information-the medium speed as the target characteristic information of the history video segment a.

In step S605, the video segment to be deleted is determined based on the target characteristic information of the history video segment.

In an optional embodiment, the electronic device may determine, according to a preset feature priority, a history video segment corresponding to the target feature information with the highest priority as a video segment to be deleted.

In another optional embodiment, the electronic device may further determine, in response to a selection operation of the user on the feature information presentation interface, a history video segment corresponding to the target feature information selected by the user as a video segment to be deleted.

In the embodiment of the present application, the manner of determining the video segment to be deleted based on the target characteristic information of the historical video segment is not specifically limited.

Through the steps S603 to S605, the electronic device can determine the video segment to be deleted according to only one preset feature information, namely the target feature information, in each history video segment, so that the complexity of the determination process of the video segment to be deleted is effectively reduced, and the efficiency of video cyclic storage is improved.

In step S606, the video segment to be deleted is deleted from the stored history video segments, and the video segment to be stored is stored.

Step S606 is the same as step S104.

In the embodiment shown in fig. 6, the target feature information is determined according to the duration of the video segment corresponding to each preset feature information in the historical video frames. In addition, the electronic device can determine the target characteristic information of the historical video segment in other ways. For example, the electronic device may determine, according to the priority of each preset feature information in the history video segment, the preset feature information with the highest priority as the target feature information of the history video segment. In the embodiment of the present application, the determination method of the target feature information is not particularly limited.

In an optional embodiment, for the preset feature information, besides the priority corresponding to each feature type, the weight of each feature type may be preset.

In an optional embodiment, when the weight of each feature type is preset, the embodiment of the present application further provides a video loop storage method. As shown in fig. 7, fig. 7 is a sixth flowchart illustrating a video loop storage method according to an embodiment of the present application. The method comprises the following steps.

In step S701, a video segment to be stored of the target vehicle is acquired.

Step S702, if the current residual storage space is less than or equal to a preset threshold, acquiring preset characteristic information of a stored historical video segment; the type of the preset characteristic information comprises driver information and/or vehicle running information.

The above steps S701 to S702 are the same as the above steps S101 to S102.

Step S703, determining the video segment to be deleted according to the weight of the feature type corresponding to the preset feature information of the historical video segment and the priority of the preset feature information.

In an optional embodiment, for each history video segment, the electronic device may calculate a weighted average or a weighted sum corresponding to each history video segment according to a weight of a feature type corresponding to preset feature information of the history video segment and a priority of each preset feature information. The electronic device can determine the history video segment corresponding to the maximum weighted average or the maximum weighted sum as the video segment to be deleted.

According to the weight of the feature type corresponding to the preset feature information of the historical video segment and the priority of each preset feature information, the video segment to be deleted is screened, so that the determined video segment to be deleted is not limited to the historical video segment with the earliest storage time, and the selectivity of the deleted video segment in the video cyclic storage process is improved.

In step S704, the video segment to be deleted is deleted from the stored history video segments, and the video segment to be stored is stored.

Step S704 is the same as step S104.

In an optional embodiment, the present application further provides a video loop storage method. As shown in fig. 8, fig. 8 is a seventh flowchart illustrating a video loop storage method according to an embodiment of the present application. The method comprises the following steps.

In step S801, a video segment to be stored of the target vehicle is acquired.

Step S802, if the current residual storage space is less than or equal to a preset threshold value, acquiring preset characteristic information of the stored historical video segment; the type of the preset characteristic information comprises driver information and/or vehicle running information.

In step S803, a video segment to be deleted is determined based on the preset feature information of the history video segment.

The above steps S801 to S803 are the same as the above steps S101 to S103.

Step S804, determining a storage space occupied by the video segment to be stored.

In this step, the electronic device may determine, according to the data size of the video segment to be stored, the size of the storage space required to be occupied by the storage of the video segment to be stored.

In an optional embodiment, the data amount of the video segment to be stored is the size of the storage space required for storing the video segment to be stored.

Step S805, determining the video segment to be deleted based on the preset characteristic information of the historical video segment and the storage space occupied by the video segment to be stored.

For example, the electronic device may screen out one or more candidate video segments to be deleted based on preset characteristic information of the historical video segments, and determine whether the added storage space can successfully store the video segments to be stored after deleting the one or more candidate video segments to be deleted based on the storage space occupied by the video segments to be stored. For example, if after a plurality of candidate video segments to be deleted are deleted simultaneously, the added storage space is not enough to store the video segments to be stored successfully, the video segments to be deleted (for example, the historical video segments with the second priority level) can be newly added until the storage space is enough; if the added storage space is larger than the storage space occupied by the video segments to be stored after the plurality of candidate video segments to be deleted are deleted simultaneously, part of the plurality of candidate video segments to be deleted can be deleted on the premise of ensuring that the video segments to be stored can be successfully stored, and unnecessary video deletion operation is avoided. If the added storage space is equal to the storage space occupied by the video segments to be stored after the plurality of candidate video segments to be deleted are deleted simultaneously, or the value of the added storage space which is larger than the storage space occupied by the video segments to be stored is smaller than a specific threshold (adaptively set), the deletion operation can be directly performed. Through the steps S804 to S805, the electronic device can ensure that the video segment to be stored can be successfully stored after the video segment to be deleted is deleted, that is, the video loop storage is ensured to be performed in order.

In step S806, the video segment to be deleted is deleted from the stored history video segments, and the video segment to be stored is stored.

Step S806 is the same as step S104.

In an optional embodiment, the present application further provides a video loop storage method. As shown in fig. 9, fig. 9 is an eighth flowchart illustrating a video loop storage method according to an embodiment of the present application. The method comprises the following steps.

In step S901, a video segment to be stored of a target vehicle is acquired.

Step S902, if the current residual storage space is less than or equal to a preset threshold, acquiring preset characteristic information of the stored historical video segment; the type of the preset characteristic information comprises driver information and/or vehicle running information.

Step S903, determining the video segment to be deleted based on the preset characteristic information of the historical video segment.

The above-described steps S901 to S903 are the same as the above-described steps S101 to S103.

In step S904, the video segment to be deleted is deleted from the stored history video segments.

Step S905, determining preset feature information of the video segment to be stored, and performing associated storage on the video segment to be stored and the determined preset feature information.

In an optional embodiment, after determining the preset feature information of the video segment to be stored, the electronic device may establish a corresponding relationship between the video segment to be stored and the preset feature information thereof, and store the video segment to be stored and the corresponding relationship between the video segment to be stored and the preset feature information thereof into a preset storage space.

In another optional embodiment, after determining the preset feature information of the video segment to be stored, the electronic device may mark the video to be stored according to the preset feature information of the video segment to be stored, obtain the video segment to be stored carrying the preset feature information, and store the video segment to be stored carrying the preset feature information.

In the embodiment of the present application, a manner of obtaining feature information of a video in a video storage process is not particularly limited. For example, during the process of acquiring the video to be stored or acquiring the video, the current driver-related information or vehicle driving-related information can be synchronously acquired for subsequent associated storage. For another example, the geographic location of the vehicle may be determined by a vehicle positioning technology, the type of the road on which the vehicle is traveling may be determined by vehicle positioning and road name matching, the vehicle traveling speed may be determined from vehicle operation data, the traffic information may be determined by capturing real-time traffic broadcast information, and the driver information may be determined by performing face acquisition and recognition on the current driver.

Through the step S905, the preset characteristic information corresponding to each video segment is stored, so that the preset characteristic information of each historical video segment can be conveniently determined by the electronic equipment in the circulating storage process, the time length required for acquiring the preset characteristic information of the historical video segment is effectively shortened, the time length required for determining the video segment to be deleted is shortened, and the efficiency of circulating storage of the video is improved.

In another optional embodiment, the embodiment of the present application further provides a video loop storage method. As shown in fig. 10, fig. 10 is a ninth flowchart illustrating a video loop storage method according to an embodiment of the present application. The method comprises the following steps.

In step S1001, a video segment to be stored of the target vehicle is acquired.

Step S1002, if the current residual storage space is less than or equal to a preset threshold, acquiring preset characteristic information of a stored historical video segment; the type of the preset characteristic information comprises driver information and/or vehicle running information.

Step S1003, determining the video segment to be deleted based on the preset characteristic information of the historical video segment.

The steps S1001 to S1003 are the same as the steps S101 to S103.

Step S1004, determining at least two candidate feature information of the video segment to be stored, and determining a corresponding video segment duration of each candidate feature information in the video segment to be stored.

In this step, when the video segment to be stored includes at least two pieces of feature information (i.e., candidate feature information), the electronic device may respectively determine a duration of the video frame corresponding to each candidate feature information occupied in the video segment to be stored as a duration of the video segment corresponding to each candidate feature information in the video segment to be stored.

For the sake of understanding, the description will be made taking the candidate feature information of the video segment B to be stored in the travel speed type as an example. Assume now that the length of time for video segment B to be stored is 10 minutes. In the 10-minute driving process of the vehicle corresponding to the video segment B to be stored, the vehicle drives at a low speed for 4 minutes first, and then at a medium speed for 6 minutes. Therefore, the candidate feature information of the video segment B to be stored at the running speed includes low and medium speeds. The electronic device may determine that the video segment duration corresponding to the candidate feature information of the video segment B to be stored being the low speed is 4 minutes, and the video segment duration corresponding to the candidate feature information of the video segment B to be stored being the medium speed is 6 minutes.

Step S1005, determining preset feature information of the video segment to be stored from at least two candidate feature information based on the corresponding video segment duration of each candidate feature information in the video segment to be stored.

In an optional embodiment, the candidate feature information with the longest duration of the corresponding video segment in the at least two candidate feature information may be determined as the preset feature information of the video segment to be stored.

Still taking the video segment B to be stored as an example, since the duration of the video segment corresponding to the candidate feature information-low speed is less than the duration of the video segment corresponding to the candidate feature information-medium speed, the electronic device can determine the candidate feature information-medium speed as the preset feature information of the video segment B to be stored.

Step S1006, the video segment to be stored and the determined preset characteristic information are stored in a correlated manner.

The step S905 can be referred to for the association storage between the video segment to be stored and the determined preset feature information, which is not described herein again.

Through the steps S1004 to S1006, while the video segment to be stored and the preset feature information thereof are ensured to be stored in association, the number of the feature information associated with the video segment to be stored can be one by determining the preset feature information of the video segment to be stored from the at least two candidate feature information, and the number of the preset feature information corresponding to each stored video segment is ensured to be one, so that the number of the preset feature information associated with the video segment is effectively reduced, on the premise that the video has the feature information available for video screening, the determination of the video segment to be deleted later is facilitated, the time length required by the determination of the video segment to be deleted is shortened, and the efficiency of video cyclic storage is improved.

Based on the same inventive concept, according to the video circular storage method provided by the embodiment of the application, the embodiment of the application also provides a video storage device. Reference may be made to the above description for details which are not explained in detail in the following examples.

Optionally, the first determining module 1103 may be specifically configured to determine the video segment to be deleted according to a weight of a feature type corresponding to preset feature information of the historical video segment and a priority of the preset feature information.

Compared with the prior art in which the history video segment with the earliest storage time is directly deleted, in the embodiment of the application, because the preset characteristic information of each stored history video segment has a certain difference, that is, the driver information, the vehicle driving information and the like corresponding to each history video segment have a certain difference, when the video segment to be stored is obtained each time, the video segment to be deleted determined according to the preset characteristic information of the stored history video segment will be different, so that each stored history video segment can be determined as the video segment to be deleted, the determined video segment to be deleted is not limited to the history video segment with the earliest storage time, and the selectivity of the deleted video segment in the video loop storage process is improved.

Moreover, when the video segment to be deleted is determined according to the preset characteristic information of the stored historical video segment, the historical video segment with the specific characteristic information can be deleted with pertinence and priority, and the pertinence of the reserved video segment is effectively improved.
