Description

Technical Field

[0001] The present invention relates to the technical field of law enforcement recording, and in particular to a target tracking method, system and medium. Background Art

[0002] A law enforcement recorder is a forensics technical equipment that is worn on the body during official duties and integrates functions such as real-time video and audio recording, photography, and recording. At the same time, it can transmit real-time video wirelessly through 4G / 5G, and can digitally record the dynamic and static on-site situations during the law enforcement process, making it convenient to use in various environments. When conducting law enforcement activities such as on-site disposal and on-the-spot punishment of some specific behaviors, a law enforcement recorder is used to record the on-site law enforcement video and audio, truthfully recording the on-site law enforcement situation.

[0003] However, current law enforcement recorders can often only capture the scene in front of the wearer, and usually multiple devices are used for joint law enforcement during the law enforcement process. When a person with a relatively obvious movement suddenly appears during the law enforcement process, usually the wearers will focus on the person with the more obvious movement in the scene and cannot record the situation of other objects at the scene, resulting in problems such as incomplete recording of the on-site situation.

[0038] Embodiment 1

[0039] Figure 1 FIG. 1 is a flowchart of a target tracking method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of recording a law enforcement scene. The method is applied to a smart terminal, the smart terminal includes a camera, and the method is also applied to a target tracking system. The target tracking system includes at least one smart terminal and a background server. The target tracking device can be configured in an electronic device. As Figure 1 shown, the method includes:

[0040] S110. Obtain video data through the camera.

[0041] In this embodiment, the smart terminal can be understood as a device with camera and processing functions. For example, it can be a law enforcement recorder, etc. The smart terminal is usually worn on the chest of a law enforcement officer in a wearable manner for recording the law enforcement scene by recording video.

[0042] Specifically, when the smart terminal is powered on and working, the camera can be automatically turned on, and the smart terminal can take pictures through the camera and obtain the captured video data.

[0043] S120. Generate a terminal message according to the video data, where the terminal message includes at least one frame of picture information in the video data.

[0044] In this embodiment, the terminal message can be understood as a message used to trigger target detection. The picture information can be understood as pictures obtained by splitting the video data frame by frame.

[0045] Specifically, the smart terminal can extract each frame of picture in the video data and generate a terminal message for detection, where the terminal message includes at least one frame of picture information in the video data.

[0046] S130. Determine whether there is a tracking target according to the terminal message, where the tracking target includes important persons or dangerous items.

[0047] In this embodiment, the tracking target can be understood as a target that needs to be continuously tracked and photographed currently. For example, it can include important persons or dangerous items, where important persons can be preset or determined by means of behavior recognition, etc. Dangerous items refer to items that are harmful to the human body, etc.

[0048] Specifically, the intelligent terminal can analyze and identify terminal messages. For example, an important person library and / or dangerous items can be preset. The intelligent terminal analyzes the target of the picture information of the terminal message by querying the database to determine whether there is a tracking target in the terminal message.

[0049] S140. In the case of the existence of a tracking target, obtain an automatic tracking instruction, and generate a tracking message according to the automatic tracking instruction. The tracking message is used to indicate the existence of a tracking target.

[0050] Optionally, the tracking message includes one of the following: voice broadcast, vibration, light, and human-computer interaction page option.

[0051] In an embodiment, the automatic tracking instruction is generated by the intelligent terminal or sent by the server, and is used to determine the target to be tracked and photographed. The tracking message is a message used to prompt the user of the intelligent terminal that there is a tracking target. The tracking message can be displayed on the intelligent terminal in various forms. For example, it can include voice broadcast, vibration, light flashing, and generating human-computer interaction page options to prompt the user that there is a tracking target. Among them, the human-computer interaction page option can be to mark the target in the shooting screen, request the user of the intelligent terminal to confirm whether to track the target, or provide multiple tracking targets for the user to select. Specifically, since the intelligent terminal is worn on the law enforcement personnel, due to the different facing directions of the law enforcement personnel, there may or may not be a tracking target in the video captured by the intelligent terminal. The intelligent terminal can generate a tracking message according to the automatic tracking instruction, and the tracking message is used to indicate the existence of a tracking target.

[0052] Exemplarily, after generating the tracking message, it is displayed to the law enforcement personnel to whom the intelligent terminal belongs through the human-computer interaction page option on the display screen configured by the intelligent terminal. The tracking target can be marked in the human-computer interaction page option, so that the law enforcement personnel can select the object to be tracked and photographed from the human-computer interaction page option. For example, the law enforcement personnel can select by touch, button, voice, etc., so as to determine to automatically track the selected object. If the law enforcement personnel do not select within the set time, the tracking will be automatically started. Further, after generating the tracking message, the intelligent terminal can also use the sound and light device configured by the intelligent terminal to give a specific light and sound (such as a flashing light combined with a prompt sound) prompt. The above prompt methods of voice broadcast, vibration, light, and human-computer interaction page option can be executed simultaneously, such as while performing a voice broadcast, the intelligent terminal vibrates to prompt the existence of a tracking target.

[0053] The technical solution of the embodiment of the present invention is applied to a smart terminal, which includes a camera. The method includes: obtaining video data through the camera; generating a terminal message according to the video data, where the terminal message includes at least one frame of picture information in the video data; determining whether there is a tracking target according to the terminal message, and the tracking target includes important persons or dangerous goods; in the case of the existence of a tracking target, obtaining an automatic tracking instruction and generating a tracking message according to the automatic tracking instruction, and the tracking message is used to indicate the existence of a tracking target. By identifying the tracking target of the video data and determining the automatic tracking instruction, a tracking message is generated to prompt law enforcement officers to determine the target for tracking. The reasonable allocation of the tracking object for each smart terminal is realized, so that law enforcement officers can clearly identify the tracking target to ensure the accurate recording of the on-site situation.

[0054] Optionally, determining whether there is a tracking target according to the terminal message can be achieved by querying the local target database of the smart terminal. The smart terminal compares the picture information in the terminal message with the information in the local target database; determines whether there is a tracking target in the terminal message according to the comparison result, where the tracking target is one of the targets in the local target database.

[0055] In this embodiment, the local target database can be understood as a database in the smart terminal for storing the characteristics of important persons or dangerous goods, which can be updated at any time. The comparison result can be understood as whether there is a target in the picture information that matches the local target database.

[0056] Specifically, the smart terminal can query the local target database of the smart terminal and compare the picture information in the terminal message with the information in the local target database. The comparison method can be, for example, machine learning recognition, etc., which is not limited in this application. The smart terminal can determine whether there is a tracking target in the terminal message according to the comparison result, where the tracking target is one of the targets in the local target database.

[0057] Optionally, the determination of the tracking target can also be performed through the server. The smart terminal sends the terminal message to the server, and the terminal message includes at least one frame of picture information in the video data. The server queries the target database for the picture information to determine whether there is a tracking target. When there is a tracking target, an automatic tracking instruction is sent to the smart terminal to inform the smart terminal that the terminal message includes a tracking target.

[0058] Further, when uploading the terminal message to the server so that the server queries whether there is the tracking target in the terminal message, the terminal message further includes auxiliary information for enabling the server to determine whether the smart terminal meets the collaborative working conditions; the auxiliary information includes at least one of the following: location information, event information, and the group where the smart terminal is located.

[0059] Specifically, the server can receive terminal messages uploaded by multiple intelligent terminals, and multiple terminals may be in the same event. For example, multiple law enforcement officers handle an event simultaneously. At this time, it can be considered that these multiple intelligent terminals meet the conditions for collaborative work.

[0060] In one embodiment, multiple intelligent terminals may exist simultaneously at a law enforcement scene, and there may be multiple tracking targets at this law enforcement scene. To ensure that as many tracking targets as possible are not missed, the server can screen out all intelligent terminals that can perform collaborative work at this law enforcement scene according to pre-set collaborative work conditions. Auxiliary information can be understood as attribute information used to determine whether an intelligent terminal meets the collaborative work conditions. For example, it can include location information, event information, and information about the group to which it belongs. Among them, the location information can be used to indicate the current location of the intelligent terminal. Event information can be understood as attribute information corresponding to the event occurring at the current law enforcement scene, such as the police situation number (a number generated by the police situation server after receiving an alarm, which can unify information when processing this police situation subsequently), the event name address, and the event type, etc. The group can be understood as the law enforcement group to which the law enforcement officers belong, which can make it easier to find intelligent terminals within the same group.

[0061] Specifically, the intelligent terminal can also be equipped with a positioning device to determine the location of the intelligent terminal and generate location information; the intelligent terminal can also include a pre-set event information table, which can automatically determine event information such as the police situation number, event type, and name address according to the situation at the time of the alarm; by means of assigning a group number to each corresponding intelligent terminal for each law enforcement officer belonging to a group, the intelligent terminal can synthesize one or more of the location information, event information, and group information as auxiliary information, and comprehensively generate a terminal message in combination with the captured picture information and upload it to the server, so that the server can query whether there are tracking targets in the terminal message and judge whether the intelligent terminal meets the collaborative work conditions in combination with the auxiliary information.

[0062] Further, when the server determines the existence of a tracking target through the terminal message, the server will send an automatic tracking instruction to the intelligent terminal, which includes the tracking target determined by the server.

[0063] Further, in the case of multiple tracking targets, an automatic tracking instruction is obtained, where the automatic tracking instruction enables the intelligent terminal to track one of the multiple tracking targets. For example, when there are multiple tracking targets, one tracking target can be selected and informed to the intelligent terminal according to selection methods such as the importance level of the tracking targets and the distance between multiple tracking targets in the picture.

[0064] In one embodiment, since the tracking target can be determined locally by the smart terminal, it can also be determined by the server. Since the determination methods and databases of the smart terminal and the server may be different, the determined tracking targets may be different. For example, the tracking targets saved in different databases are different. It is possible that the database of the server is larger than the local database of the smart terminal. In this case, there may be a situation where the smart terminal cannot recognize the tracking target that only exists in the server database locally. Therefore, the server can simultaneously receive the tracking targets determined locally by each smart terminal uploaded by the smart terminals, and the server can make a judgment by combining the tracking targets determined by each smart terminal itself, assign a suitable tracking target to each smart terminal, and generate an automatic tracking instruction to be sent to the smart terminal. The smart terminal can obtain the automatic tracking instruction to determine which target to track.

[0065] Further, send the current tracking status information of the smart terminal to the server, where the current tracking status information includes the target information of the target currently tracked by the smart terminal; when the smart terminal continuously loses the tracking target in the captured image within a preset time, generate a tracking request and send it to the server.

[0066] In this embodiment, the current tracking status information can be understood as being used to feedback the actually tracked target and the tracking status. The target information can be understood as the actual tracking target determined by the smart terminal based on the actual captured image. The preset time can be understood as the time threshold for determining whether the tracking fails. The tracking request can be understood as the request for feedbacking the tracking failure and reassigning the target.

[0067] Specifically, due to the instability of the on-site target, it may cause the target to change and the smart terminal is worn on the law enforcement personnel, and the law enforcement personnel will move at any time, so it cannot be guaranteed that the corresponding tracking target is captured in real time. Then the smart terminal can determine the target that continuously appears in the captured image in the captured image. This target can be the tracking target or other targets, and generate the current tracking status information, and can send the current tracking status information of the smart terminal to the server. The current tracking status information includes the target information of the target currently tracked by the smart terminal. When the smart terminal continuously loses the tracking target in the captured image within a preset time, the smart terminal can generate a tracking request, request the information of the current tracking target or other target information and send it to the server.

[0068] Further, the smart terminal includes a rotating camera, obtains the automatic tracking instruction, and generates a tracking message according to the automatic tracking instruction, including:

[0069] Determine whether it is in the automatic tracking mode; when the smart terminal is in the automatic tracking mode, generate a camera control instruction according to the automatic tracking instruction, and control the rotating camera to rotate so that the tracking target remains in the captured image.

[0070] In this embodiment, the rotating camera is a camera that can rotate its shooting angle. For example, the camera may include a motor. The automatic tracking mode can be understood as a mode for controlling the camera to lock and track a target. The camera control instruction can be understood as an instruction for controlling the rotation of the camera.

[0071] Specifically, the intelligent terminal can determine whether it is in the automatic tracking mode, where the automatic tracking mode can be manually turned on by law enforcement officers or automatically turned on after obtaining an automatic tracking indication. When the intelligent terminal is in the automatic tracking mode, the intelligent terminal can determine the position of the tracking target of the automatic tracking indication in each frame of the captured image, and can use the tracking target at the center of the captured image, etc. as the control target to determine how to adjust the camera, so as to obtain a camera control instruction and control the rotation of the rotating camera to keep the tracking target in the captured image.

[0072] The technical solution of the embodiment of the present invention determines the tracking target by means of the local target database of the intelligent terminal itself and / or uploading terminal messages to the server, so as to screen out the tracking target in the image captured by the camera. In the presence of a tracking target, the tracking target can be determined through the automatic tracking indication feedback by the server, and a tracking message can be generated to remind law enforcement officers by at least one of voice broadcast, vibration, lighting, and human-computer interaction page options, realizing the reasonable allocation of the tracking object for each intelligent terminal and making law enforcement officers clear about the tracking target. By rotating the camera and based on the captured image and the automatic tracking instruction, the shooting angle of the camera is automatically adjusted to realize the automatic tracking shooting of the tracking target, ensuring the integrity and timeliness of the records of the law enforcement instrument. The intelligent terminal can also feedback the current tracking status information to the server in real time, so that the server can determine the target information currently tracked by the intelligent terminal and provide support for the collaborative work of multiple intelligent terminals. When the intelligent terminal continuously loses the tracking target within a preset time, a tracking request can be generated and fed back to the server to make the server allocate the tracking target again. This ensures the stability of tracking and further ensures the comprehensive recording of the on-site situation.

[0073] Embodiment 2

[0074] Figure 2 The following is a flowchart of a target tracking method provided by the second embodiment of the present invention. This embodiment is applicable to the situation of recording the law enforcement scene. This method is applied to the server, and this method is also applied to the target tracking system. The target tracking system includes at least one intelligent terminal and the server. The target tracking device can be configured in an electronic device. As Figure 2 shown, the method includes:

[0075] S210. Receive terminal messages uploaded by at least one intelligent terminal, where the terminal messages include at least one frame of picture information in the video data acquired by the intelligent terminal.

[0076] Specifically, the server may receive terminal messages uploaded by at least one intelligent terminal, and the terminal messages include at least one frame of picture information in the video data acquired by the intelligent terminal.

[0077] S220. Determine whether there is a tracking target in each terminal message according to the respective terminal messages.

[0078] Specifically, the server may identify and analyze the picture information in the terminal message to determine the targets included therein. A target library may be pre-constructed, and by means of machine learning or the like, the targets included in the picture information are compared with the target library to determine whether there is a tracking target in the picture information.

[0079] S230. In the case where there is a tracking target, send an automatic tracking instruction to the intelligent terminal corresponding to the terminal message with the tracking target, where the automatic tracking instruction is used to indicate the tracking target for the intelligent terminal to track.

[0080] Specifically, in the case where there is a tracking target, the server may generate an automatic tracking instruction to represent the selected tracking target, and send the automatic tracking instruction to the intelligent terminal of the terminal message with the tracking target, so as to inform the intelligent terminal of the tracking target to be tracked through the automatic tracking instruction.

[0081] The technical solution of the embodiment of the present invention is applied to a server. The server receives terminal messages uploaded by at least one intelligent terminal, where the terminal messages include at least one frame of picture information in the video data acquired by the intelligent terminal; determines whether there is a tracking target in each terminal message according to the respective terminal messages; and in the case where there is a tracking target, sends an automatic tracking instruction to the intelligent terminal corresponding to the terminal message with the tracking target, where the automatic tracking instruction is used to indicate the tracking target for the intelligent terminal to track. By identifying the terminal messages of the intelligent terminal by the server, the tracking target is determined and an automatic tracking instruction is sent to the intelligent terminal. The reasonable allocation of the tracking objects for each intelligent terminal is realized, enabling law enforcement officers to clarify the tracking target to ensure the accurate recording of the on-site situation.

[0082] Further, when the terminal message further includes auxiliary information, determine whether the intelligent terminal meets the collaborative working conditions according to the auxiliary information; the auxiliary information includes at least one of the following: location information, event information, and the group where the intelligent terminal is located.

[0083] Specifically, the terminal message may further include auxiliary information for providing more detailed event and smart terminal conditions through location information, event information, and the group where the smart terminal is located. The server can determine, through the auxiliary information, whether the smart terminal meets the collaborative working conditions in ways such as within the range of the area where the smart terminal is located, having the same event number as the smart terminal, or being in the same group, etc., to determine whether the smart terminal can work collaboratively with other smart terminals. When the smart terminal meets the collaborative working conditions, after the server determines that any terminal in the collaborative working group has a tracking target, it can instruct multiple smart terminals that meet the collaborative working conditions to jointly assist in tracking the target, improving the overall work efficiency.

[0084] Optionally, the server may receive a tracking request sent by the smart terminal, where the tracking request includes auxiliary information; according to the tracking request, send a tracking feedback to the smart terminal according to preset allocation conditions, where the tracking feedback includes tracking location information.

[0085] In this embodiment, the preset allocation conditions can be understood as conditions for re-determining the tracking target, and can be allocated according to priorities or target distances, etc. The tracking feedback can be understood as feedback information for indicating the target to be tracked. The tracking location information can be the location of the previously allocated tracking target, or the location of other targets that need to be tracked.

[0086] Specifically, the server can receive a tracking request sent by the smart terminal, re-allocate the target to be tracked by the smart terminal, provided that the tracking request includes auxiliary information. The server can, according to the auxiliary information in the tracking request, send a tracking feedback to the smart terminal according to preset allocation conditions, where the tracking feedback includes tracking location information. Among them, the preset allocation conditions can be to re-determine the tracking target according to the above-mentioned tracking target determination method and feedback the tracking location information of the tracking target; it can also determine whether there is a tracking target of the smart terminal that sent the tracking request through the current tracking status information fed back by other smart terminals. If so, the location of the tracking target can be determined as the tracking location information and fed back to the smart terminal in the form of a tracking feedback; it can also determine the tracking target allocated this time through priorities, etc.; it can also allocate the tracking target through the distance between the target in the picture information and the smart terminal, etc.

[0087] Optionally, the server receives the current tracking status information sent by at least one smart terminal, where the current tracking status information includes the target information currently tracked by the smart terminal; records the tracking target corresponding to each smart terminal, and generates and stores a real-time tracking mapping table.

[0088] Since the tracking target indication sent by the server may be the target recommended for tracking, which may not be consistent with the target actually tracked by the law enforcement officers, the intelligent terminal can feedback the actually tracked target to the server for recording, so that the server can continue the subsequent collaborative work allocation, so as to avoid missing a certain tracking target in the case of multiple tracking targets and multiple intelligent terminals working collaboratively.

[0089] In this embodiment, the target information can be understood as the information used to distinguish the tracking target. The real-time tracking mapping table may include the mapping relationship between each intelligent terminal and its tracking target.

[0090] Specifically, the server can receive the current tracking status information sent by at least one intelligent terminal, and the current tracking status information includes the target information currently tracked by the intelligent terminal. The server can establish the mapping relationship between each intelligent terminal and the corresponding current tracking target, generate and store the real-time tracking mapping table, providing guidance for subsequent tracking target allocation and tracking feedback.

[0091] Further, based on the above embodiment, the step of sending an automatic tracking indication to the intelligent terminal corresponding to the terminal message with a tracking target in the case of a tracking target can be refined as:

[0092] The server queries whether there is a tracking target in the received multiple terminal messages; identifies N intelligent terminals that can work collaboratively according to the multiple terminal messages; in the case of M tracking targets, sends automatic tracking indications to the N intelligent terminals respectively according to the preset allocation conditions, where both M and N are greater than 1.

[0093] Specifically, the server queries whether there are tracking targets in the multiple terminal messages received. The server can identify N intelligent terminals that can work collaboratively based on the multiple terminal messages according to the above collaborative working conditions. In the case of M tracking targets, the server can send automatic tracking instructions to the N intelligent terminals respectively according to the preset allocation conditions. When N > M, the server can determine whether there are missing tracking targets in the N terminal messages received. When there are missing tracking targets, the intelligent terminal for finally tracking the target can be selected by means such as the distance between the tracking target and the intelligent terminal, and the other intelligent terminals targeting the tracking target can be reallocated. When reallocating, the real-time tracking mapping table can be referred to to ensure that there is no phenomenon of missing tracking; when N < M, the allocation can be performed by means such as the priority of the tracking target or the distance relative to each intelligent terminal, and the N intelligent terminals can be allocated to the more important or relatively closer tracking targets among the M tracking targets. Another example is that there are N terminals that can work collaboratively, and the server only identifies that there are M tracking targets in the terminal messages of K terminals among the N terminals, where N > K. The server can send automatic tracking instructions to the N terminals that can work collaboratively according to other methods such as positioning and grouping, and allocate the M tracking targets existing in the K terminal messages.

[0094] Exemplarily, the server can identify intelligent terminals in the same regional scope through the positioning information in the terminal message; the server can also identify intelligent terminals in the same regional scope through the video pictures in the terminal message; the server can also determine intelligent terminals that can work collaboratively for handling the same event according to the working group and event information in the terminal message.

[0095] Among them, when there is only one intelligent terminal, it corresponds to a single-person law enforcement scenario, and the subsequent allocation can be to identify the priority of the M tracking targets.

[0096] The technical solution of the embodiment of the present invention is that the server receives the terminal messages of the intelligent terminals, judges the collaborative working conditions based on the auxiliary information therein, divides the intelligent terminals belonging to the same law enforcement area, and then combines the preset allocation conditions to allocate tracking targets to each intelligent terminal that works collaboratively, and establishes a real-time tracking mapping table of the relationship between each intelligent terminal and the tracking target through the current tracking status information to ensure the reasonable allocation of the tracking targets, so as to avoid the situation of missing shooting and repeated shooting of the objects at the law enforcement scene. By analyzing the auxiliary information of the intelligent terminal that issues the tracking request, the tracking targets are allocated to the intelligent terminals again, and the tracking position information is provided, ensuring the timeliness and reasonableness of the allocation. Furthermore, the comprehensiveness of the on-site situation record is improved.
