Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

First, an execution subject and an application scenario of the embodiment of the present invention will be described.

An execution main body

The execution subject of the embodiment of the invention can be a server or a management platform based on monitoring information.

Second, application scenario

The application scenario of the embodiment of the present invention is a monitoring scenario based on a monitoring device, and therefore, the application scenario generally includes: monitoring equipment and a server.

The monitoring device is used to collect monitoring information, for example, the monitoring device may include a video monitoring device such as a Camera and an IPC (IP Camera), may also include an audio monitoring device such as a sound pickup, and may also include a monitoring device such as a radar that is used to collect a position of an object. Based on the above, the monitoring information may include: monitoring video, monitoring images, monitoring audio, point cloud data, and the like.

The server is used for obtaining information which is obtained according to the monitoring information collected by the monitoring equipment and is used for describing the specified event.

The designated event can be a traffic accident event, a property safety event and other alarm events. For example: the traffic accident event can be vehicle rear-end collision and vehicle congestion, and the property safety event can be theft, robbery and the like. Therefore, the specific events to be monitored in different actual scenarios are different, for example: the traffic accident event can be mainly monitored in a vehicle driving road, and the property safety event can be mainly monitored in a region with dense pedestrian flow, such as a subway station and a high-speed rail station.

The information for describing the specified event may include: the start time of the event, the end time of the event, the event type, the device identification of the monitoring device, and the like.

In addition to the above concepts, the embodiments of the present invention also relate to concepts such as first description information, second description information, third description information, event detection, and the like. In the application scenario, the functions of the monitoring device and the server that need to be completed in different specific implementations are different, that is, the specific scenarios are different. Therefore, for clarity in describing these concepts, reference is made below to specific scenarios.

In addition, since the first description information, the second description information, and the third description information are all information for describing a specified event, the first description information, the second description information, and the third description information are collectively referred to as description information for convenience of description.

The first specific scenario: and after the monitoring equipment collects the monitoring information, event detection is carried out according to the collected monitoring information to obtain the description information. And the monitoring equipment sends the description information to the server. The server receives the description information, stores the description information and can also retrieve the event information based on the stored description information.

The second specific scenario: the monitoring device collects monitoring information. For each monitoring device, the server performs event detection according to the monitoring information acquired by the monitoring device to obtain the description information corresponding to the monitoring device, stores the description information, and can also perform event information retrieval based on the stored description information.

Specifically, when the server performs event detection according to the monitoring information collected by the monitoring device to obtain the description information corresponding to the monitoring device, in an embodiment, each monitoring device may send the collected monitoring information to the server. And the server receives the monitoring information and performs event detection according to the received monitoring information to obtain the description information corresponding to the monitoring equipment.

In another embodiment, the monitoring device may further store the collected monitoring information in the storage device. And the server acquires the monitoring information from the storage equipment, and performs event detection according to the acquired monitoring information to obtain the description information corresponding to the monitoring equipment.

The third concrete scenario: the scene may include a detection device in addition to the monitoring device and the server. The detection device is used for detecting an event according to the monitoring information to obtain the description information corresponding to the monitoring device.

In this case, the monitoring device collects monitoring information. For each monitoring device, the detection device performs event detection according to the monitoring information acquired by the monitoring device to obtain description information corresponding to the monitoring device, and the detection device sends the description information corresponding to the monitoring device to the server. The server receives the description information, stores the description information and can also retrieve the event information based on the stored description information.

Specifically, when the detection device performs event detection according to the monitoring information collected by the monitoring device to obtain the description information corresponding to the monitoring device, in an embodiment, each monitoring device may send the collected monitoring information to the detection device. The detection equipment receives the monitoring information and carries out event detection according to the received monitoring information to obtain the description information corresponding to the monitoring equipment.

In another embodiment, the monitoring device may further store the collected monitoring information in the storage device. The detection device acquires the monitoring information from the storage device, and performs event detection according to the acquired monitoring information to obtain the description information corresponding to the monitoring device.

In the three specific scenarios, event detection is performed according to the monitoring information, and description information corresponding to the monitoring device is obtained. Specifically, in event detection, in an embodiment, object identification may be performed on each object in which monitoring information appears, and if information of a preset object is identified, it may be considered that a specified event is detected to start to occur. In another embodiment, the event detection may also be performed according to the position and sound volume of each object appearing in the monitoring information, for example: when the positions of the objects appearing in the monitoring information are close and the sound is noisy, it can be considered that the specified event is detected to start to occur. In another embodiment, the detection of the event may be performed according to the action characteristics of each object appearing in the monitoring information, for example: when the action of the object appearing in the monitoring information is a preset action or the action amplitude is large, it can be considered that the specified event is detected to start to occur.

When it is detected that the specified event has started to occur, the specified event may be associated with monitoring information, so that information describing the specified event may be determined based on the monitoring information. For example: assuming that a vehicle collision event is detected from the monitoring information 1, the detected vehicle collision event is associated with the monitoring information 1, and based on the vehicle collision event occurring in the monitoring information 1, the occurrence time, end time, identification of the monitoring device, event type, and the like of the vehicle collision event may be determined.

It should be noted that, in the embodiment of the present invention, the three specific scenarios are merely used as examples for description, and the specific scenarios are not limited.

The following describes in detail an event information storage method and an event information retrieval method provided by embodiments of the present invention, respectively, by using specific embodiments.

Referring to fig. 1, fig. 1 is a schematic flowchart of a first event information storage method according to an embodiment of the present invention, where the method includes S101 to S103.

S101: first description information which is obtained according to the first monitoring information and is used for describing a specified event is obtained.

The first monitoring information includes: monitoring information collected by the source monitoring equipment after the first detection of the specified event begins to occur. The source monitoring equipment comprises: and the monitoring equipment is used for collecting source monitoring information. The source monitoring information is: the first time monitoring information is detected upon which the specified event begins to occur.

For example: suppose when the information I is recognized₁₁When it is time, it indicates that the specified event is detected to begin occurring. When monitoring equipment C₁Collected monitoring information I₁Is recognized as information I₁₁When it is, the monitoring information I can be considered₁Monitoring information, namely source monitoring information, according to which the occurrence of a specified event is detected for the first time; monitoring equipment C₁The monitoring equipment for collecting source monitoring information is source monitoring equipment.

Specifically, the source monitoring device is generally in a state of collecting monitoring information during the working process, and based on this, monitoring information collected after a first detection of a specified event starts to occur in the monitoring information collected by the source monitoring device is referred to as first monitoring information. Of course, the event is also ended as time goes on, and the monitoring information collected by the source monitoring device after the event is ended is no longer the first monitoring information.

For example: assume that the first detection of a specified event begins to occur at the time: at 10 am on 1/2020, the monitoring information collected by the source monitoring device after 10 am on 1/2020 belongs to the first monitoring information. In addition, if the time ends at 11 am on 1/2020, the monitoring information acquired by the source monitoring device after 11 am on 1/2020 does not belong to the first monitoring information, that is, the monitoring information acquired by the source monitoring device between 10 am and 11 am on 1/2020 belongs to the first monitoring information.

In an embodiment of the present invention, the first description information may include at least one of the following information: the starting time and the ending time of the first monitoring video, the image index of the snapshot image of the source monitoring equipment, the equipment identification of the source monitoring equipment, the storage address of the first monitoring video and the like.

The first monitoring video is as follows: and the source monitoring equipment acquires monitoring videos which are used for describing the specified events after the first detection that the specified events begin to occur.

S102: and obtaining second description information which is obtained according to the second monitoring information and is used for describing the specified event.

The second monitoring information is: monitoring information collected by the first associated device after a specified event is started is detected for the first time according to the first associated monitoring information. For example: suppose that the first time a specified event is detected to start to occur according to the first associated monitoring information is: and 10 am and 30 am on 1 month and 1 month in 2020, the monitoring information collected by the first associated device after 10 am and 30 am on 1 month and 1 month in 2020 belongs to the second monitoring information.

Assuming that, when the first time the specified event is detected to start to occur, the detected event is the event M, the first time the specified event is detected to start to occur according to the first associated monitoring information may be understood as: the first time, the event M is detected to start to occur according to the first associated monitoring information.

In an embodiment of the present invention, the second description information may include at least one of the following information: the starting time and the ending time of the second monitoring video, the image index of the snapshot image of the first associated device, the device identification of the first associated device, the storage address of the second monitoring video and the like.

The second monitoring video is as follows: and the monitoring video which is collected by the first association equipment and used for describing the specified event after the first time that the specified event starts to be detected according to the first association monitoring information.

The first associated monitoring information is: monitoring information collected by the first associated device after the first detection of the initiation of the specified event.

The first associated device is: and the monitoring equipment has an association relation with the source monitoring equipment. For example: suppose monitoring device SC₁And monitoring equipment SC₂、SC₃Have an association relationship between them, and monitor the equipment SC₁Is a source ofA monitoring device for monitoring the SC after the first detection of the specified event₂The collected monitoring information detects that a specified event starts to occur according to the monitoring equipment SC₃The collected monitoring information does not detect that a specified event starts to occur, in which case it will be based on the monitoring equipment SC₂And information for describing the specified event is obtained from the collected monitoring information and is used as second description information.

The association relationship between the monitoring devices may be determined in a variety of ways: in one embodiment, the association relationship may be a relationship predetermined by an operator based on experience.

In another embodiment, the relationship between the monitoring devices may also be determined according to the distance between the monitoring devices. For example: when the distance difference between the monitoring devices is smaller than a preset difference threshold, it can be determined that the monitoring devices have an association relationship.

In yet another embodiment, in addition to considering the distance between monitoring devices, the relationship between monitoring devices may be determined in conjunction with the type of monitoring device. For example, when the distance difference between the monitoring devices is smaller than a preset difference threshold and belongs to the same type, it may be determined that there is an association relationship between the monitoring devices.

S103: event information including the first description information and the second description information is stored.

The event information includes first description information and second description information of the event, and the first description information and the second description information are: and obtaining information for describing the specified event according to the monitoring information collected by the monitoring equipment with the incidence relation. That is, for each piece of event information, the piece of event information includes: and obtaining information for describing the specified event according to the monitoring information collected by the monitoring equipment with the incidence relation.

Specifically, the event information may be stored in a preset storage address. The above event information may also be stored in a storage device.

As can be seen from the above, when the scheme provided by this embodiment is applied to store event information, the stored event information includes first description information and second description information of a specified event corresponding to the piece of event information, where the first description information is obtained according to monitoring information acquired by a source monitoring device after the specified event is detected to start occurring for the first time and is used for describing the specified event, the second description information is obtained according to monitoring information acquired by a first associated device after the specified event is detected to start occurring for the first time according to the first associated monitoring information and is used for describing the specified event, and the first associated device is a monitoring device having an association relationship with the source monitoring device. In this way, each piece of event information includes information for describing a specific event, which is obtained from monitoring information collected by each monitoring device having an association relationship. In addition, because the information for describing the specified event is obtained according to the monitoring information collected by each monitoring device with the association relationship, compared with the information for describing the specified event which is obtained by taking the monitoring device as a unit in the prior art, the integrity of the stored information for the specified event can be improved when the scheme provided by the embodiment of the invention is applied to storing the event information.

In addition, the first monitoring information and the second monitoring information are respectively acquired after the source monitoring device and the associated device of the source monitoring device start detecting that the specified event starts, and because the first monitoring information and the second monitoring information are both used for obtaining the description information of the specified event, it can be seen that not only the obtaining of the information for describing the specified event for the source monitoring device but also the obtaining of the information for describing the specified event for the associated device is triggered when the first detection of the specified event starts. Compared with the prior art, the information for describing the event is not obtained any more only when the starting occurrence of the specified event is detected according to the monitoring information collected by each monitoring device. In the embodiment of the invention, as long as the specified event is detected to start to occur based on the monitoring information acquired by the source monitoring equipment, the information acquisition for describing time for the associated equipment can be triggered.

Based on the above situation, when the description information for describing the specified event is obtained by each monitoring device, and the event is obtained by the monitoring device, it may be considered that the source monitoring device starts to generate the specified event when detecting the specified event for the first time according to the collected monitoring information, and may trigger the source monitoring device to obtain the description information of the specified event according to the collected monitoring information, and may trigger the associated device to obtain the description information of the specified event according to the collected monitoring information.

Referring to fig. 2, fig. 2 is a schematic flowchart of a second event information storage method according to an embodiment of the present invention. On the basis of the above-described embodiment, storing event information including the first description information and the second description information in the above-described S103 may be implemented as following S103a1-S103a 2.

S103A 1: a source device identification is obtained.

The source device identifier is used for characterizing: and acquiring the monitoring equipment which detects the monitoring information according to which the specified event starts to occur for the first time, namely the equipment identifier of the source monitoring equipment.

The source device identifier may include a serial number, an installation location, a network address, and the like of the source monitoring device, and may further include an identifier of a connection channel between the source monitoring device and the server.

Specifically, the source device identifier is obtained, and the source device identifier may be determined from pre-stored device identifiers of each monitoring device; an identification obtaining request can also be sent to the source monitoring device, so as to obtain the source device identification.

S103A 2: storing event information including a source device identification, first description information, and second description information.

Since the source monitoring device is a monitoring device that collects source monitoring information, that is, monitoring information on which the first occurrence of a specified event is detected, and the source monitoring information represents the start of the occurrence of the specified event, the source monitoring device can be regarded as the first monitoring device that detects the start of the occurrence of the specified event, that is, the source that detects the start of the occurrence of the specified event. Thus, when the device identifier of the source monitoring device is stored in the event information, it can be clearly indicated that the source of the specified event is detected to start to occur, and the event information can also be indicated as the information of the specified event monitored by the source monitoring device as the main monitoring device. In this way, based on the stored event information, the specific situation of the specified event described by each event information can be determined more accurately.

In an embodiment of the present invention, after the source monitoring device detects that the specified event starts to occur, the source monitoring device may further capture an image, and in this case, the first description information may further include an image index of the image captured by the source monitoring device. In view of the above, it is possible to obtain the first image index and obtain information obtained from the first monitoring information and describing the specified event, thereby obtaining first description information including the first image index and the obtained information.

The first image index is used for characterizing: and the source monitoring equipment captures the storage address of the image after the first detection of the occurrence of the specified event.

Similarly, in another embodiment of the present invention, after the source monitoring device detects that the specified event starts to occur for the first time, the source monitoring device may also directly or indirectly control the first associated device to capture the image, in which case, the second description information may also include an image index of the image captured by the first associated device. In view of the above, it is possible to obtain the second image index and obtain the information for describing the event obtained from the second monitoring information, thereby obtaining the second description information including the second image index and the obtained information.

The second image index is used for characterizing: the storage address of the first associated equipment snapshot image after the start of the specified event is detected for the first time according to the first associated monitoring information.

In this way, since the description information includes the image index, the snapshot image of the monitoring device can be obtained according to the image index in the description information.

Since the event development can be a dynamic development process, after the first detection of the initiation of the specified event, the specified event may be detected according to the monitoring information collected by other monitoring devices as the event develops. In order to make the information of the specified event recorded by the event information richer and more comprehensive, in an embodiment of the present invention, after the above S102, third description information obtained according to the third monitoring information and used for describing the specified event may also be obtained.

The third monitoring information includes: and monitoring information collected by the second associated equipment after a specified event is started is detected for the first time according to the second associated monitoring information. For example: suppose that the first time when the specified event starts to occur is detected according to the second associated monitoring information is: 11 am on 1/2020, the monitoring information collected by the second associated device after 11 am on 1/2020 belongs to the third monitoring information.

In an embodiment of the present invention, the third description information may include at least one of the following information: the starting time and the ending time of the third monitoring video, the image index of the snapshot image of the second associated device, the device identification of the second associated device, the storage address of the third monitoring video and the like.

Wherein, the third monitoring video is: and the monitoring video is collected by the second associated equipment after the specified event is detected to start according to the second associated monitoring information for the first time and is used for describing the specified event.

The second associated monitoring information is: monitoring information collected by the second associated device after the first detection of the initiation of the specified event.

The second association device is: and monitoring devices except the source monitoring device and the first association device in the monitoring devices having association relation with the first association device.

On the basis of the above-described embodiment, in one embodiment of the present invention, event information including the first description information, the second description information, and the third description information may be stored.

Therefore, the event information further comprises third description information, the third description information is information which is obtained according to the third monitoring information and is used for describing the specified event, when the specified event is a dynamically developed event, the process of the specified event can be reflected more comprehensively through the third description information, and therefore the event information can reflect the information of the specified event corresponding to the event information more completely.

In an embodiment of the present invention, a retrieval request for the event information may also be obtained, and the event information matching the retrieval request is retrieved from the stored event information, so as to obtain a retrieval result.

Corresponding to the event information storage method, the embodiment of the invention provides an event information retrieval method.

Referring to fig. 3, fig. 3 is a schematic flowchart of a first event information retrieval method according to an embodiment of the present invention, where the method includes S301 to S302.

S301: a retrieval request for event information is obtained.

The search request is used for requesting to search the event information. Specifically, the retrieval request may carry retrieval information such as a time period of occurrence of an event, an event type, and a device identifier of the monitoring device.

In one embodiment of the invention, a user can input a retrieval condition aiming at event information in a user interface of a client used by the user, the client generates a retrieval request containing the retrieval condition and sends the retrieval request to a server, and the server obtains the retrieval request.

S302: and searching the event information matched with the searching request from the stored event information to obtain a searching result.

In an embodiment of the present invention, each piece of stored event information may be stored in a manner provided in each of the foregoing event information storage embodiments, and details are not described here again.

For convenience of description, the monitoring information collected by the source monitoring device after the first detection of the occurrence of the specified event may be referred to as first monitoring information. For example: assume that the first detection of a specified event begins to occur at the time: at 10 am on 1 st of 2020, the first monitoring information is: monitoring information collected by the source monitoring device after 10 am on 1/2020.

Specifically, the end time of the first monitoring information may be a time when the end of the event is detected for the first time. In addition, when event detection is performed in cycles, if an event is not detected from the monitoring information within the duration of one cycle, the time in this case may be determined as the end time of the first monitoring information.

The source monitoring apparatus includes: and the monitoring equipment is used for collecting source monitoring information. The source monitoring information includes: the first time monitoring information is detected upon which the specified event begins to occur.

The second monitoring video includes: and after detecting that the specified event starts to occur for the first time according to the first associated monitoring information, acquiring a monitoring video for describing the specified event according to the first associated equipment.

For convenience of description, the monitoring information collected by the first associated device after the first time the first associated monitoring information detects that the specified event starts may be referred to as second monitoring information. For example: suppose that the first time a specified event is detected to start to occur according to the first associated monitoring information is: and 10 am and 30 am on 1 month and 1 day of 2020, the second monitoring information is: monitoring information collected by the first associated device after 30 minutes at 10 am on 1/2020.

The first associated monitoring information includes: monitoring information collected by the first associated device after the first detection of the initiation of the specified event. The first association device includes: and the monitoring equipment has an association relation with the source monitoring equipment.

For example: suppose monitoring device SC₁And monitoring equipment SC₂、SC₃Have an association relationship between them, and monitor the equipment SC₁For the source monitoring device, after the first detection of the start of the specified event, if it is according to the monitoring device SC₂The collected monitoring information detects that a specified event starts to occur and is based on the monitoring equipment SC₃The collected monitoring information does not detect that a specified event starts to occur, in which case it will be based on the monitoring device SC₂And information for describing the specified event is obtained from the collected monitoring information and is used as second description information.

The association relationship between the monitoring devices may be determined in a variety of ways: in one embodiment, the association relationship may be a relationship predetermined by an operator based on experience. In another embodiment, the relationship between the monitoring devices may also be determined according to the distance between the monitoring devices. For example: when the distance difference between the monitoring devices is smaller than a preset difference threshold, it can be determined that the monitoring devices have an association relationship. In yet another embodiment, in addition to considering the distance between monitoring devices, the relationship between monitoring devices may be determined in conjunction with the type of monitoring device. For example, when the distance difference between the monitoring devices is smaller than a preset difference threshold and belongs to the same type, it may be determined that there is an association relationship between the monitoring devices.

Specifically, the event information may be stored in a server or a storage device.

In the event information retrieval, event information matching the retrieval condition may be specified from among the pieces of event information as a retrieval result based on the retrieval condition included in the retrieval request.

For example: assuming that the time period of occurrence of an event included in the search request for event information is 9 am — 11 am on 1 st of 2020 and the event type is a vehicle rear-end collision type, the stored pieces of event information are shown in table 1 below:

TABLE 1

Based on the search condition and each piece of event information, it is possible to specify that the piece of event information matching the search condition is event information 1, and the event information 1 can be used as a search result.

As can be seen from the above, when the scheme provided by this embodiment is applied to retrieve event information, since each piece of stored event information includes the first description information and the second description information of the specified event corresponding to the piece of event information, the first description information is information which is obtained according to monitoring information collected by the source monitoring equipment after the first detection of the start of the specified event and is used for describing the specified event, the second description information is information which is obtained according to monitoring information collected by the first associated equipment after the first detection of the start of the specified event according to the first associated monitoring information and is used for describing the specified event, the first associated equipment is monitoring equipment which has an association relation with the source monitoring equipment, in this way, each piece of event information includes information for describing a specific event, which is obtained from monitoring information collected by each monitoring device having an association relationship. And because the information for describing the specified event is obtained according to the monitoring information collected by each monitoring device with the incidence relation, compared with the information for describing the specified event which is obtained by taking the monitoring device as a unit in the prior art, the integrity of the retrieved event information is higher. Therefore, when the scheme provided by the embodiment is applied to the event information retrieval, the integrity of the retrieved information of the specified event can be improved.

In an embodiment of the present invention, the event information may further include a source device identifier.

The source device identifier is used for characterizing: and collecting monitoring equipment which detects the monitoring information according to which the specified event starts to occur for the first time. I.e. the device identification of the source monitoring device.

When the source device identifier is stored in each piece of event information, the event information can be retrieved based on the source device identifier, so that the first description information and the second description information in the event information can be obtained, that is, the information of the specified event monitored by the source monitoring device and the information of the specified event monitored by the first associated device are obtained, and the retrieval of each piece of event information is realized mainly by the source monitoring device.

For example: in order to be able to retrieve event information of a vehicle collision occurring at intersection a, assuming that a vehicle collision occurs at intersection a, event information including an identifier of monitoring device X may be retrieved from stored pieces of event information based on the identifier of monitoring device X provided at intersection a, so that event information of a vehicle collision monitored by monitoring device X and event information of the same vehicle collision monitored by an associated device with monitoring device X are obtained from the retrieved event information.

Therefore, as each piece of event information comprises the source equipment identifier, the retrieval of each piece of event information can be realized by mainly using the source monitoring equipment.

In one embodiment, the information display mode may be preset by an operator according to experience. In this case, a preset information presentation manner may be used as the information presentation manner.

In another embodiment, the information presentation mode may be selected by the user on the client used by the user. In this case, the information presentation manner selected by the user and transmitted by the client can be obtained.

S304: and displaying the information of the specified event corresponding to the event information in the retrieval result according to the information display mode.

Specifically, when displaying the information of the specified event corresponding to the event information in the search result, the information to be displayed of the specified event corresponding to the event information in the search result may be determined according to the type of the information to be displayed included in the information display manner, and then each determined information to be displayed is displayed according to the information display manner.

For example: the information display mode is assumed to include the type of information to be displayed and the layout of each information display, wherein the type of the information to be displayed includes: channel information, start and stop times of events, event type, and source information. Wherein, the channel information includes: the identifier of the channel corresponding to the source monitoring device and the device identifier of the monitoring device.

Assuming that the user interface includes information items such as "channel", "start/end time", "event type", "source", and the like, the device identifier of the source monitoring device is: IPCamera01, the identifier of the channel corresponding to the source monitoring device is D2. The device identifiers of the associated devices having an association relationship with the source monitoring device are respectively: IPCamera02, IPCamera03, IPCamera04, IPCamera05, IPCamera 06. In this case, the information recorded in the "channel" item in the user interface may be a combination of D2 and the identifiers of the respective devices, e.g., D2_ IPCamera01, D2_ IPCamera02, etc., and the information recorded in the "start/end time" item may be the start/end time of the above event, the information recorded in the "event type" item may be "movement detection", and the information recorded in the "source" item may be the IP address "10.9.96.177" of the source monitoring device.

Thus, when information is presented through the user interface, the user can intuitively know that the source monitoring device IPCamera01 triggers IPCamera02-IPCamera06 to monitor for the same specified event, that is, channel D2 triggers IPCamera02-IPCamera06 to monitor for the same specified event, that is, the monitoring information collected by IPCamera01-IPCamera06 at the "start-stop time" item is related to the same specified event. In addition, relevant information monitored by IPCamera01-IPCamera06 for the same specified event can be intuitively understood.

On the basis of the information displayed by the user interface, the user can also obtain the monitoring video and/or the snapshot image acquired by the IPCamera02-IPCamera06 triggered by the channel D2 and the monitoring video and/or the snapshot image acquired by the IPCamera 01.

In addition, the monitoring videos and the snapshot images corresponding to the records can be displayed in the user interface respectively.

Therefore, after the retrieval result is obtained, the information of the specified event corresponding to the event information in the retrieval result is displayed, so that the user can clearly and intuitively know the retrieval result and know the information of the specified event corresponding to the retrieved event information.

Referring to fig. 5, fig. 5 is a flowchart illustrating a third event information retrieval method according to an embodiment of the present invention. Based on the above embodiment, the displaying of the information of the specified event corresponding to the event information in the search result in the information displaying manner in S304 can be realized according to the following S304B1-S304B 2.

The monitoring videos may include a monitoring video collected by the source monitoring device and a monitoring video collected by the first associated device after the first detection of the occurrence of the specified event.

And when the event information in the retrieval result contains the image index of the snapshot image and the storage address of the monitoring video. In this case, the captured image and/or the surveillance video of the specified event corresponding to the event information in the retrieval result may be obtained based on the image index and the storage address. Specifically, the snapshot image and/or the monitoring video may be stored in a server, and may also be stored in a storage device.

S304B 2: and displaying the obtained snapshot image and/or the obtained monitoring video according to an information display mode.

Specifically, when the information display mode is to simultaneously display each captured image and/or each monitored video, each obtained captured image and/or each obtained monitored video may be simultaneously displayed according to the information display mode.

In an embodiment of the present invention, the information displaying method may be: and displaying the snapshot image. After each snapshot image is displayed to the user according to the information display mode, the user can select the display mode of the monitoring video according to the displayed snapshot image. Assume that the presentation mode selected by the user is: displaying each monitoring video, wherein in this case, each monitoring video can be displayed simultaneously in a plurality of windows of the user interface; assume that the presentation mode selected by the user is: only the monitoring video collected by the source monitoring device is displayed, in this case, the monitoring video collected by the source monitoring device may be displayed in the user interface, and it is assumed that the display mode selected by the user is: the surveillance video is not shown, in which case the surveillance video is not shown.

Therefore, after the retrieval result is obtained, the snapshot image and/or the monitoring video are displayed based on the retrieval result, so that the user can know the specific situation of the event information corresponding to the specified event more clearly and intuitively.

Specifically, when an image index exists in the description information, the captured image can be obtained according to the image index.

The image index is used for representing the storage address of the snapshot image.

In this case, it is indicated that the first description information and/or the second description information has an image index. Therefore, the storage address of the snapshot image can be determined according to the image index, and then the snapshot image can be obtained from the determined storage address.

When the description information does not have the image index of the snapshot image, the image can be obtained according to the monitoring video corresponding to the video information recorded in the description information and used as the snapshot image.

In this case, it is indicated that there is no image index in both the first description information and the second description information. At this time, the monitoring video can be obtained according to the video information recorded in the description information, and the image is obtained based on the obtained monitoring video and is used as the snapshot image.

In an embodiment of the present invention, the video information may include information such as a storage address of the monitoring video, a video identifier, and the like.

When an image is obtained as a snapshot image based on the obtained monitoring video, a video frame of the monitoring video can be captured as the snapshot image, and a plurality of video frames of the monitoring video can be subjected to image fusion to obtain a fused video frame as the snapshot image.

In this way, when the image index of the snapshot image does not exist in the description information, the snapshot image can be obtained more accurately because the image is obtained as the snapshot image according to the monitoring video corresponding to the video information recorded in the description information.
