However, the image AI algorithm can only track after locking the accident or the object appearing in the camera range.

[0029] The following will be described in conjunction with the accompanying drawings Figures 1-3 The present application is further described.

[0030] As Figure 1 shown, Figure 1 is a structural schematic block diagram of an automatic tracking camera device provided by an embodiment of the present application, which comprises a camera, a driving module and a plurality of sensing modules with different sensing areas:

[0031] The camera is used for tracking photography;

[0032] Each sensing module is used for physical sensing and outputting a corresponding target position sensing signal, and the combined angle of the sensing angles of the plurality of sensing modules is greater than the photography angle of the camera;

[0033] The driving module is connected with the camera and the plurality of sensing modules respectively, and is used for driving the camera to rotate according to the target position sensing signal output by one sensing module, so as to make the camera track photography on the target position.

[0034] It can be understood that the automatic tracking camera can be used for automatic recording to monitor the surrounding environment when the automatic tracking camera is applied, and therefore the automatic tracking camera can be applied in various scenarios, for example, in the field of monitoring security, the automatic tracking camera can be used as a vehicle parking monitoring driving recorder, and can also be used for real-time monitoring in public places such as shopping malls, banks, airports and the like to improve the security protection capability. In addition, the device can also be applied in sports events to capture the wonderful moments of athletes, or in wild animal observation to automatically track the activities of animals, or in industrial production lines, the automatic tracking camera can monitor the production process in real time to ensure production quality and efficiency.

[0035] In the embodiment, the camera of the automatic tracking camera is used for tracking photography. The tracking photography can be continuous tracking photography of a specific target by combining the camera and related technical means, and the main purpose is to ensure that the target is within the camera range when the target moves. The camera realizes tracking photography by identifying the target to be tracked by image recognition technology and locking the target for continuous tracking. The camera can be a near-focus lens applied in vehicle monitoring, a fixed-focus lens used in scenarios requiring high-resolution and high-quality images, a zoom lens used in scenarios requiring adjustment of the shooting range and angle of view, a wide-angle lens used in monitoring large-area scenarios, a long-focus lens used in long-distance photography, or a fisheye lens, a panoramic camera, and the like.

[0036] The sensing module is used for entity sensing, which refers to detecting and identifying the existence, position, motion state or other attributes of an entity object (such as a person, an animal, a vehicle or other moving objects). When the automatic tracking camera is applied in different scenarios, the entity sensing can be used for sensing different attributes and different objects. For example, when applied in a vehicle parking monitoring driving recorder, the entity sensing can detect the existence of an entity including a person, an animal, a vehicle or other objects with entity, and determine the specific position of the entity, which can be two-dimensional (such as plane coordinates) or three-dimensional (including height information). In an embodiment, the sensing module can also identify whether the entity is moving, judge the direction and speed of the movement, and analyze the shape and size of the entity, and the like. The sensing module can include at least one of an optoelectronic sensing sensor module, an infrared sensing sensor module, an ultrasonic sensing sensor module, a radar sensing sensor module, and the like.

[0037] In the embodiment, the sensing angle of the sensing module refers to the maximum range angle of the object or event that can be detected by the sensing module, which is usually expanded from the central axis of the sensing module to both sides to form a fan-shaped detection area. Within the area, the sensing module can trigger a signal when an object moves or changes. The camera angle refers to the angle of the image range that can be captured by the camera, which is also expanded from the central axis of the camera to both sides to form a camera area. The camera angle determines the field of view range that can be covered by the camera, i.e., the width of the area that can be imaged on the image sensor.

[0038] The sensing module has multiple, each of which is the same, and each of which can be used for entity sensing and outputting a corresponding target position sensing signal, i.e., each module outputs its own target position sensing signal. For example, the sensing module includes a first sensing module, a second sensing module, and a third sensing module, and the corresponding target position sensing signals include a first target position sensing signal, a second target position sensing signal, and a third target position sensing signal. It can be understood that the installation angle of each sensing module can be different, so that the sensing area of each sensing module is different, and therefore the target position sensing signal output by each sensing module is different for different regions. Through multiple sensing modules, a larger range of sensing can be achieved. For example, the sensing module has three, each with a sensing angle of 120°, and the three sensing modules are installed to allow each sensing module to sense a range of 120°. In this way, 360° sensing can be achieved. Similarly, the sensing module has four, each with a sensing angle of 90°, and the four sensing modules are installed to allow each sensing module to sense a range of 90°. In this way, 360° sensing can be achieved.

[0039] Based on this, the combined angle of the sensing angles of multiple different sensing modules is greater than the camera angle of the camera. For example, when the camera is a wide-angle camera with a camera angle of up to 270°, the combined sensing angle of multiple sensing modules with different installation angles is greater than 270°, thereby achieving sensing outside the camera's field of view blind area.

[0040] The driving module is used to drive the camera to rotate. The driving module can be driven by a motor, or can be driven by a hydraulic or pneumatic device. The driving module is connected with the camera and the plurality of sensing modules respectively. The target position sensing signal output by each sensing module can be sent to the driving module. The driving module can determine the entity position according to the target position sensing signal output by any one of the sensing modules, and then drive the camera to rotate to the entity position. In an embodiment, the camera angle of the camera is the same as the sensing angle of one sensing module. The driving module can directly drive the camera to rotate according to the sensing module sending the target position sensing signal, so that the camera angle of the camera is the same as the sensing angle of the sensing module sending the target position sensing signal. When the camera angle of the camera is greater than the sensing angle of one sensing module, the driving module can analyze the target position sensing signal, determine the entity position, and then drive the camera to rotate, so that the entity position is in the camera range of the camera. When the camera angle of the camera is less than the sensing angle of one sensing module, the driving module can analyze the target position sensing signal, determine the entity position, and then drive the camera to rotate, so that the entity position is in the camera range of the camera. When the camera cannot track and photograph the target position, the driving module continues to drive the camera to rotate according to the latest target position sensing signal, so that the camera can always photograph the entity.

[0041] It can be understood that the camera can always keep the camera recording open. When there is no entity change, the camera will not track and photograph the entity in the picture. When the entity in the picture changes, the camera will track and photograph the entity. Therefore, the camera keeps the camera recording open. After the driving module drives the camera to rotate, the camera can capture the entity change in the picture and track and photograph the entity target. In this way, the content photographed by the automatic tracking camera device is more comprehensive. The camera can also start camera recording according to the entity change in the picture. That is, the camera recording is started only when the entity in the picture changes. Before the driving module drives the camera to rotate and when there is no change in the entity in the picture, the camera starts photographing but does not start camera recording. After the driving module drives the camera to rotate, when the entity in the picture changes, the camera starts photographing and starts recording. In this way, the camera can save the storage space of the photographed content.

[0042] In an embodiment, the sensing module and the camera can be installed in a protective shell. The protective shell includes an upper shell and a lower shell. The camera is installed in the upper shell, and the sensing module is fixed in the lower shell by a buckle. The position of the buckle is set according to the angle of the sensing module, so as to form a large sensing range. The driving module is connected with the upper and lower shells. When any one of the sensing modules detects an object, the driving module drives the camera of the upper shell to rotate.

[0043] In an embodiment, the driving module can be connected with a control unit, the control unit controls the movement of the driving module according to the target position sensing signal, so as to adjust the pointing direction of the camera, the control unit is embedded with a smart algorithm, which can analyze the signal provided by the sensing module in real time and calculate the optimal camera rotation angle to ensure that the target is always in the center of the camera field of view, the control unit also has a self-calibration function, which can automatically adjust the positioning of the camera according to the change of the environment to ensure the accuracy and stability of the tracking.

[0044] In the automatic tracking camera device provided in some embodiments of the present application, the camera is used to determine the tracking target of the camera, and based on the tracking target, the camera enters a locked tracking state to lock and track the tracking target.

[0045] It can be understood that the camera can also analyze the content in the camera picture when taking pictures to determine the entity in the picture and the movement of the entity to determine the target entity that needs to be tracked. It can be understood that there are usually multiple different entities in the camera picture of the camera, and the camera can be set with corresponding conditions to determine the entity that needs to be tracked when applied in different scenes. For example, when applied in a security monitoring scene, a rule can be set to track targets with a moving speed exceeding a certain threshold, automatically identify and track a face when a face is detected, determine an entity as a target that needs to be tracked as long as the entity moves, and the like. In addition, there can be multiple entities that meet the conditions in the camera range, and the specific entity that needs to be tracked can be further determined. For example, an entity with a high moving speed can have a higher priority than an entity with a low moving speed, an entity with a specific size or shape can have a higher priority, and the like.

[0046] Based on this, after the tracking target is determined, the camera enters a locked tracking state based on the tracking target, that is, the current tracking target is locked as an entity target that needs to be tracked and photographed, so as to lock and track the determined tracking target. In this way, after the camera enters the locked tracking state, if there are other entities that meet the conditions in the camera range, the camera will not track and photograph these entities, so as to ensure that the camera can accurately track the tracking target and perform clearer camera recording.

[0047] In the automatic tracking camera device provided in some embodiments of the present application, the driving module is used to stop responding to the target position sensing signal output by all sensing modules when the camera enters the locked tracking state.

[0048] It can be understood that when the camera enters the locked tracking state, if there is no target position sensing signal output by other sensing modules, the camera range of the camera does not change, and even if there are other entities in the camera range of the camera that meet the conditions, the camera will not track and photograph these entities, and even if other sensing modules have sensing and output target position sensing signals, the driving module will stop responding to the target position sensing signals output by all sensing modules after the camera enters the locked tracking state, so the camera angle of the camera will not change, the camera range of the camera does not change, and the camera only tracks and photographs the tracking target.

[0049] In the automatic tracking camera device provided in some embodiments of the present application, the camera is configured to stop determining the tracking target when the camera enters the locked tracking state.

[0050] It can be understood that when the camera enters the locked tracking state, it means that the camera has determined the tracking target, but there can be multiple entities in the camera range of the camera that meet the conditions. In order to ensure accurate tracking and photographing of the current tracking target, the camera can stop determining the tracking target, that is, stop judging the target entity that needs to be tracked, that is, when the camera is tracking and photographing the current tracking target, it can only analyze the content in the camera image to track and photograph the tracking target, without judging the target entity that needs to be tracked.

[0051] In the automatic tracking camera device provided in some embodiments of the present application, the sensing distance of the sensing module is not less than the locked tracking camera distance of the camera.

[0052] It can be understood that the sensing distance of the sensing module is different from the sensing angle of the sensing module, and the locked tracking camera distance of the camera is also different from the camera angle of the camera. The sensing distance of the sensing module can refer to the maximum distance at which the sensing module can effectively detect a target object. This distance is the straight-line distance from the position of the sensing module to the target position that can trigger the reaction of the sensing module. The locked tracking camera distance of the camera can refer to the maximum distance at which the camera can maintain clear identification and stable tracking of a specific target when tracking the target.

[0053] In some embodiments, the sensing distance of the sensing module is the same as the locked tracking camera distance of the camera. In this way, through the sensing module, when an entity approaches the range of the same distance, the camera will turn to the position detected and fed back by the sensing module to record and capture the image.

[0054] In some embodiments, the sensing distance of the sensing module is greater than the locking tracking camera distance of the camera, so that when an entity enters the sensing distance of the sensing module without entering the locking tracking camera distance of the camera, the camera can be turned to the position where the sensing module detects feedback in advance through the driving module, and the camera recording is started, so as to realize early warning and pre-opening of the recording, and enhance the early warning capability of the automatic tracking camera device.

[0055] In the automatic tracking camera device provided in some embodiments of the present application, the camera determines the tracking target of the camera through an artificial intelligence image recognition algorithm.

[0056] In the present embodiment, the camera determines the tracking target of the camera through an artificial intelligence image recognition algorithm. Specifically, the camera can analyze the content in the camera picture through an artificial intelligence image recognition algorithm, so as to judge the entity in the picture and the movement of the entity, and then determine the target entity to be tracked through a preset screening rule.

[0057] In the automatic tracking camera device provided in some embodiments of the present application, the driving module includes a driving motor and a controller, the controller is connected with the driving motor and the sensing module respectively, the driving motor is used to drive the camera to rotate, and the controller is used to receive the target position sensing signal and control the driving motor according to the target position sensing signal.

[0058] In the present embodiment, the driving module includes a driving motor and a controller, wherein the driving motor is used to provide driving power for driving the camera to rotate, and the controller provides a control signal for the driving motor, that is, provides a rotation amount for driving the camera, therefore, the target position sensing signal output by the sensing module is sent to the controller, the target position sensing signal is analyzed in detail through the controller, the specific position of the tracking target to be tracked by the camera is judged, and then the rotation amount required by the camera is determined according to the specific position of the tracking target, so as to control the driving motor.

[0059] In the automatic tracking camera device provided in some embodiments of the present application, the driving module further includes a warning communication module, the warning communication module is used to send the target position sensing signal to a user terminal in communication connection with the automatic tracking camera device when the controller receives the target position sensing signal.

[0060] In the embodiment, the early warning communication module is configured to send the target position sensing signal to a user terminal in communication connection with the automatic tracking camera device when the controller receives the target position sensing signal. Specifically, the controller can first confirm the sensing signal to ensure that it is not a false alarm or interference signal. After the confirmation, the early warning communication module converts the target position sensing signal into a digital data packet and sends the data packet to the user terminal in communication connection with the automatic tracking camera device through wired or wireless network (such as Ethernet, Wi-Fi, 4G / 5G, etc.). The user terminal can be a computer system of a monitoring center, a mobile device of a user, or an alarm receiving device of a manager, etc.

[0061] In the automatic tracking camera device provided in some embodiments of the present application, as shown in Figure 2 and Figure 3 , the automatic tracking camera device includes three sensing modules, the sensing angle of each sensing module is not less than 120°, and the combined angle of the sensing angles of the plurality of sensing modules is not less than 360°, and the rotation angle of the camera is 360°.

[0062] It can be understood that the rotation angle of the camera is 360°, that is, the camera can realize 360° dead angle-free monitoring, and the automatic tracking camera device includes three sensing modules, the sensing angle of each sensing module is not less than 120°, and the combined angle of the sensing angles of the plurality of sensing modules is not less than 360°, that is, the plurality of sensing modules can also realize 360° dead angle-free sensing. In an embodiment, referring to Figure 2 and Figure 3 , Figure 2 FIG. 4 is a front view of the automatic tracking camera device provided in another embodiment of the present application, Figure 3 FIG. 5 is a bottom view of the automatic tracking camera device provided in another embodiment of the present application. In the figure, the automatic tracking camera device includes three sensing modules, the three sensing modules are arranged at the bottom of the camera, and the sensing angle of each sensing module is 120°. The sensing ranges of the sensing modules do not overlap, so that the sensing angles of the three sensing modules form 360°, which is consistent with the 360° rotation angle of the camera. In this way, both the sensing module and the camera can realize 360° view angle.

[0063] In the automatic tracking camera device provided in some embodiments of the present application, the sensing module is a 5.8G radar sensing module.

[0064] In the embodiment, the 5.8G radar sensing module can detect through high-sensitivity millimeter waves. The 5.8G radar sensing module can detect weak breathing or even heartbeat signals to determine the presence of a human body without large-scale movement of the human body. Therefore, the 5.8G radar sensing module is adopted as the sensing module to improve the sensing sensitivity.

[0065] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
