The specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.

Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

Along with the improvement of people's security consciousness, the disadvantage of simple camera video early warning system in the aspect of comprehensive information processing gradually exposes. The pure video early warning system of the video camera can not meet the security requirements of people.

Therefore, the development of the camera gateway with the video monitoring function and capable of being used as various sensors and home controller hubs has great significance in comprehensive information processing. Therefore, the video monitoring system not only can utilize the function of video monitoring, but also can be combined with various sensors and controller equipment to configure more applications, so that the application flexibility is expanded, and the system richness is improved. The security system which is built by taking the camera as the center can present the information monitored by various sensors to the user in a more friendly mode in video information processing, and the security system can accurately and technically inform the user when an early warning event occurs, so that the user can conveniently check dangerous cases.

Based on this, the embodiment of the application provides a video acquisition system. As shown in fig. 1a, the video acquisition system includes an acquisition end, a network device, and a client. The acquisition end can combine the monitoring state of various sensors in a certain time period in the process of acquiring the video, and different labels can be added to the video content in the time period. The acquisition end can transmit the video after the label is added to the network equipment for storage or local storage. The network device can respond to the query request transmitted by the client and feed the corresponding video back to the client so as to be convenient for the client to check. The network device in the embodiment of the present application may be a server or a local gateway.

Referring to fig. 1b to 1d, fig. 1b to 1d are different architectures of the video capturing system respectively. Fig. 1b is a schematic diagram of a architecture corresponding to a single gateway, and as shown in fig. 1b, the video acquisition system includes a trigger device, an execution device, a router, a cloud end and a client end. The triggering device comprises a door magnet 1, a human body 1, a controller 1 and the like. The door magnet 1 is a sensor for sensing opening and closing of doors and windows and consists of a magnet and a main body part of the sensing magnet. The door magnet 1 is alternatively a door magnet system using geomagnetic principle. The human body 1 is a sensor for detecting human body induction and outputting whether a human signal exists. The human body 1 is, for example, a PIR infrared detection sensor or a radar induction sensor. The controller 1 is a wireless control device, and its state can be used as a condition for triggering recording of abnormal video, for example, when a lamp is turned on, and when a power overload condition occurs. It will be appreciated that the controller 1 may learn whether a lamp on condition has occurred or whether a power overload condition has occurred.

The execution device is equivalent to the acquisition end shown in fig. 1 a. The executing device may be a camera gateway, i.e. a camera with gateway functionality. The execution device is mainly divided into two parts, wherein the first part is an audio-video related camera part, the second part is a gateway part, and the gateway part is a control center of a sensor and a controller. The hardware block diagram of the camera gateway is shown in fig. 1e, the camera is connected with a router to a local wifi network or an external network through a wifi module, and is connected with Zigbee sub-equipment (door magnet, human body, controller and other equipment in the system block diagram) through a Zigbee module. The SD card is used to store local history video (optional mating).

The router is used to connect the gateway to a local area network or an external local area network. The cloud end is a cloud end server and is used for message pushing and cloud end video storage. A client (App end); for example, a mobile phone application program, which is used for identifying video colors generated by abnormal events. Displaying real-time video, video recording, abnormal video, video recording identification with color, and the like.

Fig. 1b shows that the triggering device and the executing device are in the same gateway, and the information of the triggering device can be directly sent to the executing device.

Referring to fig. 1c, fig. 1c shows that the trigger device and the execution device are under different gateways, but under the same local area network. The information of the trigger device needs to be transferred to the execution device side through the router.

Referring to fig. 1d, fig. 1d shows that the trigger device and the execution device are located in different areas in spatial positions, and the information of the trigger device needs to be synchronized to the execution device through the cloud.

With continued reference to fig. 1f, fig. 1f is a main system flow chart of a video acquisition system when the marker event configuration information is stored in the camera gateway. As shown in fig. 1f, first, a user may perform a time-of-interest configuration at a client (APP) to obtain tag event configuration information. Then, local streaming is performed, and the client issues configuration information to the camera gateway (execution subject). After the event is triggered, the triggering device reports the event information to the camera gateway, and the camera gateway compares the event information with the marked event configuration information to judge whether the event triggering device is the marked event device or not, namely, whether the triggered event is the marked event or not. If yes, the event is clouded, the camera gateway sends the event information to the cloud, the cloud pushes the event information to the client (App), the client performs color marking on the display segment corresponding to the marked event in the video, and different event types can be marked by adopting preset colors respectively. When a user views the marked video, the video stream is pulled directly from the time point of starting the marking, and the video when the event is triggered is viewed.

It can be appreciated that the camera gateway can perform cloud storage and local storage on the acquired video.

With continued reference to fig. 1g, fig. 1g is a main system flowchart corresponding to the video acquisition system when the marking event configuration information is stored in the client (App). As shown in fig. 1g, when an event is triggered, the trigger device reports event information to the camera gateway, the camera gateway reports the event information to the cloud, after the cloud is pushed to the client (App), the client (App) compares the event information with preset marked event configuration information, and if the event is a preset attention event, that is, if the trigger device of the event is the marking device, the color marking set by the user is performed on the corresponding video clip. When the user views the marked video, the video stream is directly pulled from the time point to view the video when the event is triggered. When the user needs to increase the time dimension to screen the video, the user can select the interested marked video after selecting the time, so as to watch the interested video.

In the video acquisition system provided by the embodiment of the application, the scheme based on the preset event can facilitate the user to set the abnormal reminding event in the video camera (the door magnetic sensor senses that the door is opened, the human body sensor detects that someone moves, the light controller detects that the lamp is opened, and the like). And the event marking can be carried out on the video strip by adopting different colors for different triggering events, for example, the door magnetic door opening sensing mark is yellow, the human body detects that the movement mark of a person is green, and the like. When the configured abnormal reminding event occurs, the video camera stores video copies before and after the event triggering time point in the local (SD card, NAS service and the like) and cloud, and marks the event triggering position by corresponding preset colors on the app. When the user needs to view the video clips at the corresponding event, the user can directly view the preset video clips marked with the corresponding color or the video marked with the moment on the app.

The scheme based on the preset event is that an abnormal reminding event is set in the camera, corresponding time is marked, and the user can conveniently check the abnormal reminding event. But still the user is required to actively search the interested fragments from the marked videos, and the interested videos cannot be quickly positioned only by time screening.

In order to overcome the above problems, the embodiments of the present application provide a video retrieving method, which may be but not limited to be applied to the client in the foregoing, and the specific flow is as shown in fig. 2, and the video retrieving method includes:

s102, the client sends the search request to the network equipment.

The search request comprises a time search condition and a type search condition, and the search request is used for indicating the network equipment to search a target video fragment matched with the time search condition and the type search condition in a first database and generating a first search result corresponding to the search request.

The time search condition refers to a search condition of a time dimension, and specifically may be a user-defined time range, which is used for searching for a corresponding video clip from the video according to the search condition of the selected time dimension. Specifically, the time retrieval condition may include a start time and an end time, for example, the start time is 2021, 5, 1, 00 points, and the end time is 2021, 6, 1, 00 points. It will be appreciated that the time dimension is retrieved by defining a time range for the target video clip by the start time and the end time. It can be understood that the video is a video stored in the first database or a video collected by the collecting end, and the video includes video segments marked according to time nodes and event types. The target video clip is a video clip that the user needs to view.

The type search condition refers to a search condition of an event type dimension, and may include event types corresponding to various scenes, specifically may be a target event type selected by a user in a user-defined manner. Specifically, the target event types may include: a door open event, a light on event, a person passing event, a smoke concentration exceeding event, etc. In the process of collecting video, the collecting terminal can add a corresponding label for the current video according to the current event type, wherein the label carries the current event type, and the current event type can be one or more of the event types.

It is assumed that, in the time search condition, the start time is 2021, 5, 1, 00 points, the end time is 2021, 6, 1, 00 points, and the target event type in the type search condition is a door opening event. Namely, the label is video recorded video of the door opening event within 00 points from 1.00 points in 2021, 5 and 1.00 points in 2021, 6 and 1.00 points in 2021, and is a target video clip required to be acquired by the client.

S103, the client receives a first search result fed back by the network equipment.

Under the condition that no target video clip meeting the search request exists, the first search result fed back to the client by the network equipment is a no-target video clip response message; and under the condition that at least one target video segment meeting the search request exists, the network equipment packages all the target video segments into a first search result, and feeds back the first search result to the client.

According to the video searching method, after the network equipment receives the searching request, the network equipment searches from two dimensions through the time searching condition and the type searching condition, so that a large number of unnecessary video contents of the client can be rapidly eliminated, target video clips required by the client can be accurately and rapidly searched, and compared with the method for viewing each video in a certain time period one by one, the viewing time is greatly shortened, and the accuracy and the efficiency of searching are improved.

In a case that the first search result includes at least one target video segment, and each target video segment carries a corresponding acquisition time, with respect to how to improve convenience for viewing of a user, the embodiment of the present application further provides a possible implementation manner, please refer to fig. 3, and the video recording video search method further includes:

S104, the client orders at least one section of target video segments according to the acquisition time carried by the target video segments to obtain an ordering result.

For example, the first search result received by the client includes three segments of target video segments, where the collection time carried by the three segments is 2021, 5, 8, 00, and 2021, 5, 10, 00. The client can sequence the three target video clips according to the collection time carried by the target video clips, namely, the target video clips corresponding to 00 points of 2021, 5 month, 8 days, 00 points of 2021, 5 month, 9 days, 00 points of 2021 and 00 points of 2021, 5 month, 10 days, 00 points of 2021 are sequentially arranged, so that the user can conveniently watch the target video clips, and know the sequence of events.

And S105, displaying the target video clips according to the sequencing result.

With continued reference to the above example, the target video clips corresponding to 00 points 00 minutes at 5 month and 8 days in 2021, 00 points 00 minutes at 5 month and 9 days in 2021, and 00 points 00 minutes at 5 month and 10 days in 2021 are sequentially arranged, so that the user can conveniently watch, and know the sequence of events.

On the basis of fig. 2, regarding how to obtain the retrieval request, the embodiment of the present application further provides a possible implementation manner, please continue to refer to fig. 3, and the video retrieval method further includes:

S101, the client generates a search request according to the time search condition and the type search condition.

It may be understood that the time search condition and the type search condition may be input by the user on a certain page or different pages of the client, or may be transmitted to the client by another terminal, which is not limited herein.

In order to overcome the foregoing problems, the embodiments of the present application further provide a video searching method, which may be but not limited to be applied to the foregoing network device, and the specific flow is as shown in fig. 4, where the video searching method includes:

s201, receiving a search request sent by a client.

Wherein the search request includes a time search condition and a type search condition.

Possibly, the time retrieval condition comprises a start time and an end time of a target video segment, and the type retrieval condition comprises a target event type of the target video segment.

Regarding the time search condition and the type search condition in the search request, reference is made to the explanation corresponding to S102 above, and no detailed description is given here.

S209, searching target video clips matched with the time search condition and the type search condition in the first database according to the search request.

The first database comprises collected video, and the video comprises video clips marked according to time nodes and event types.

Optionally, the network device searches whether the first database stores the video satisfying both the time search condition and the type search condition, if so, the video is a target video segment, at this time, S210 is executed, and the network device determines all the target video segments as the first search result. If not, it indicates that there is no target video clip, at this time, S211 is executed, and the network device determines the response message without the target video clip as the first search result.

S210, if the video recorded in the first database comprises target video fragments of which at least a time node and a time type simultaneously meet the time search condition and the type search condition, determining all the target video fragments as a first search result.

Optionally, the first database is a database corresponding to the network device, and is used for storing video data received by the network device. After receiving the search request, the network device searches the video in the first database from two dimensions through a time search condition and a type search condition, so that a large number of unnecessary video contents of the client can be rapidly removed, and target video clips required by the client can be accurately and rapidly searched. In contrast to transmitting all videos within a certain time period, for example, all videos within the interval from 00:00 from 2021 month 1 to 00:00 from 2021 month 1, 6, 1, and 1, to the client, the video retrieval method provided in the embodiments of the present application only needs to transmit video of the type of the target event type as the target video within the interval from 00:00 from 2021 month 1 to 00:00 from 2021 month 1, 6, and 1, to the client. The number of data transmission is greatly reduced, the occupation of transmission bandwidth is reduced, meanwhile, a user is not required to check each video in a certain time period one by one, the checking time is greatly shortened, and the accuracy and the efficiency of retrieval are improved.

S212, feeding back the first search result to the client.

The user can review the first search result at the client to view the content of the target video clip of interest.

On the basis of fig. 4, it is assumed that the video includes an upload deadline, which is the latest upload time of the video; the time search condition comprises an end time and a start time, wherein the end time is the tail end of the time search condition, and the start time is the head end of the time search condition. With reference to fig. 5, the video retrieval method further includes:

s202, determining whether the video uploading deadline is later than the ending time. If not, executing S203; if yes, S209 is executed.

For example, the end time is 6 months 1 day 00 points, the video upload time is 6 months 2 days 00 points, and the video upload deadline is later than the end time. If the video uploading time is 5 months 30 days 00 points, the video uploading deadline is earlier than the ending time, and at this time, the video from 5 months 30 days 00 points to 6 months 1 days 00 points may still be stored in a local database at the acquisition end, and not uploaded to the network device.

When the transmission operation is performed on the video, the acquisition end often uploads all videos acquired by the time point to the network device.

By judging whether the video uploading deadline (the latest uploading time) is later than the ending time, the acquisition end can know whether the target video clip is possibly stored. And under the condition that the network equipment judges that the video uploading deadline is later than the ending time, the acquisition end does not store the target video fragments and uploads the target video fragments to the network equipment, S209 is executed, and the network equipment judges whether the target video fragments are stored in the first database or not, so that all the target video fragments can be completely acquired, and omission is avoided. Otherwise, the capturing end may also store the target video clip, and if further verification is required, S203 is executed.

S203, determining whether the uploading deadline is earlier than the starting time. If yes, executing S204; if not, S207 is performed.

If the upload deadline is earlier than the start time, for example, the start time is 2021, 5, 1, 00, and the upload deadline is 2021, 4, 30, 00, all the target video clips indicating the client needs are stored in the local memory of the acquisition end, and are not uploaded to the network device, at this time, in order to quickly respond to the client needs, the network device executes S204, and sends the search request to the acquisition end. The acquisition end searches in the corresponding local memory according to the search request, and feeds back a second search result obtained by searching to the network equipment, and then feeds back the second search result to the client end by the network equipment.

In one possible implementation, if the upload deadline is earlier than the start time, the network device may request that the capturing end upload all the videos and then retrieve them by the network device. Compared with the searching by the acquisition end, only the second searching result is transmitted, and more time is spent on uploading all videos to the network equipment, so that the response efficiency of the client is reduced, and the client experience is influenced.

If the upload deadline is later than the start time, for example, the start time is 2021, 5, 1, 00, the end time is 2021, 6, 1, 00, the upload deadline is 2021, 5, 25, 00, the indication that there may be some target video clips stored in the local memory of the capturing end and not uploaded to the network device, at this time, in order to respond to the client requirement quickly, S207 is executed, and the network device sends an upload instruction to the capturing end. So that the acquisition end uploads all video recorded videos from 00 minutes from 2021, 5, 25, 00 minutes to 2021, 6, 1, 00 minutes to network equipment.

S204, sending the search request to the acquisition end.

Therefore, the acquisition end searches in the corresponding local memory according to the search request, and the obtained second search result is fed back to the network equipment. The second search result comprises at least one target video segment or no target video segment response message.

The explanation of the second search result refers to the first search result, and will not be described herein.

S205, receiving a second search result fed back by the acquisition end.

S206, determining the second search result as the first search result.

Optionally, after the second search result is determined as the first search result, the network device feeds back the first search result to the client, i.e. performs S212.

S207, sending an uploading instruction to the acquisition end.

Optionally, the uploading instruction is used for driving the acquisition end to upload the video to the network device.

S208, receiving the supplementary video data uploaded by the acquisition end, and storing the supplementary video data into a first database.

The acquisition time of the supplementary video data covers the end time.

With continued reference to the above example, the upload deadline is 5 months 31 days 00 minutes, the end time is 6 months 1 day 00 minutes, and the acquisition time of the supplementary video data can be up to 6 months 8 days 00 minutes or only up to 6 months 2 days 00 minutes.

After S208, the network device will execute S209 to search the first database for a target video clip matching the time search condition and the type search condition according to the search request. Specifically, searching a target video segment matched with the time search condition and the type search condition in a first database after uploading the supplementary video data according to the search request.

In one possible implementation, the uploading instruction may carry an ending time, and the acquisition time of the supplemental video data is from the uploading ending time to the ending time, that is, from 00 points on day 5, 31, to 00 points on day 6, 1, and 00 points on day 1. Therefore, under the condition of ensuring the integrity of the target video clip, the transmission quantity of the current data is reduced, the transmission time is shortened, and the network equipment can search as early as possible, so that a first search result fed back is obtained.

S211, if the first database does not contain the target video clip, determining that the response message without the target video clip is the first retrieval result.

Optionally, the no-target video clip response message indicates that the acquisition end fails to acquire the video which simultaneously satisfies the time search condition and the type search condition.

And S212, the network equipment feeds back the first retrieval result to the client.

On the basis of fig. 4, for the content in S209, the embodiment of the present application further provides a possible implementation manner, as shown in fig. 6, S209 includes S209-1 and S209-2.

S209-1, screening preselected video clips meeting the time retrieval condition from the video recorded in the first database.

For example, the time search condition is 2021, 5, 1, 00 points 00 to 2021, 6, 1, 00 points 00. Video clips collected within 00 minutes from 00 minutes at 1.5.1.2021 to 00 minutes at 1.6.1.2021 are required to be determined as preselected video clips.

S209-2, screening out target video fragments meeting the type retrieval condition from all the preselected video fragments.

And taking the preselected video segment with the type being the target event type as a target video segment. Namely, the video clips which are collected from 00 points from 1.00.00.5.1.2021 to 00.00.00.6.1.2021 and are of the type of the target event are taken as target video clips. And transmitting the target video clip to the client. The number of data transmission is greatly reduced, the occupation of transmission bandwidth is reduced, meanwhile, a user is not required to check each video in a certain time period one by one, the checking time is greatly shortened, and the accuracy and the efficiency of retrieval are improved.

In order to overcome the foregoing problems, the embodiment of the present application further provides a video searching method, which may be but not limited to be applied to the foregoing collection end, and the specific flow is as shown in fig. 7, where the video searching method includes:

It should be noted that, the second search result is a result obtained by the acquisition end after searching according to the search request.

As described above, only uploading the second search result to the network device and uploading all video data from the start time to the end time to the network device take a shorter time and consume fewer resources.

S303, feeding back a second search result to the network equipment.

Optionally, as in S206 described above, the network device second search result is determined as the first search result. The network device can quickly feed back the first search result to the client.

With continued reference to fig. 7, assume that the time search condition includes an end time, which is the end of the time search condition. Regarding how to guarantee the integrity of the target video segment, the embodiment of the application also provides a possible implementation manner, and the video retrieval method further includes:

and S304, uploading the supplementary video data to the network equipment under the condition of receiving an uploading instruction sent by the network equipment so as to instruct the network equipment to search a target video fragment matched with the time retrieval condition and the type retrieval condition in a first database after uploading the supplementary video data.
