Description

Technical Field

[0001] The present invention relates to the field of monitoring technologies, and in particular, to a method, device, equipment, and storage medium for obtaining monitoring videos. Background Art

[0002] In the field of monitoring, low-power design can improve the battery life of camera devices and extend the continuous working time of camera devices. Therefore, low-power design has been increasingly emphasized.

[0003] Currently, low-power camera devices at least include two central processing units (CPUs), namely a microcontroller unit (MCU) and a system on a chip (SOC). Among them, the MCU is in a long-powered-on state, while the SOC is only awakened by the MCU when image processing services are required. Since the SOC is usually in a sleep state and is only awakened for service processing when there is an image processing service, the purpose of saving power can be achieved.

[0004] However, in actual application scenarios, it is usually necessary to view the monitoring videos collected by multiple camera devices in a monitoring system through a terminal device. In this scenario, since each camera device will wake up its own SOC for image processing, the power consumption of the monitoring system is still relatively large. Summary of the Invention

[0019] The main controller of the first imaging device receives the first image data sent by the main controller of the second imaging device through the second near-field communication module in the second imaging device.

[0020] A method for obtaining monitoring video provided by the present invention further includes:

[0021] The main controller of the first imaging device searches for imaging devices including near-field communication modules within a preset distance through the first near-field communication module;

[0022] The main controller of the first imaging device networks the imaging devices including near-field communication modules and the first imaging device.

[0023] A method for obtaining monitoring video provided by the present invention further includes:

[0025] A method for obtaining monitoring video provided by the present invention further includes:

[0026] When the main controller of the first imaging device determines that the identification information of the imaging device is the identification information of the first imaging device, the main controller of the first imaging device acquires third image data collected by the first imaging device;

Since when a user views the monitoring video of the second camera device, the slave controller of the first camera device can be used to process the first image data collected by the second camera device, in this way, the slave controller of the first camera device can process both its own image data and the image data of the second camera device, thus eliminating the need to wake up the slave controller of the second camera device. Therefore, the power consumption of the monitoring system can be reduced. Description of the Drawings

[0042] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0043] Currently, in a monitoring system, many camera devices are powered by solar energy. However, due to the limitation of the conversion efficiency of solar energy, how to reduce the power consumption of camera devices in the monitoring system is an important issue. Currently, an MCU and an SOC are usually provided in a low-power camera device. Among them, the MCU is in a long-powered-on state, and the SOC is usually in a sleep state. When there is an image processing task, the MCU will wake up the SOC to perform image processing, thereby reducing the power consumption of the camera device. In many application scenarios, a monitoring system includes multiple camera devices, and monitoring personnel usually need to switch the monitoring videos collected by multiple camera devices in the monitoring system through a terminal device. For example, switch from the No. 1 camera device to the No. 2 camera device. In this scenario, each camera device needs to wake up its own SOC to perform image processing and send the processed image to the terminal device. For example, when the monitoring personnel are viewing the image collected by the No. 1 camera device, the MCU of the No. 1 camera device will wake up the SOC of the No. 1 camera device to process the collected image. When the monitoring personnel switch to the No. 2 camera device, the MCU of the No. 2 camera device will wake up the SOC of the No. 2 camera device to process the collected image. Since each camera device wakes up its own SOC to perform image processing, the power consumption of the monitoring system is still relatively large, and the purpose of truly reducing power consumption cannot be achieved.

[0044] To solve the above problems, the embodiment of the present invention provides a monitoring video acquisition method. In this method, when there are multiple camera devices in the monitoring system, only the SOC of one of the camera devices in the monitoring system needs to be woken up. Using this SOC, the image data collected by all camera devices in the monitoring system can be processed, that is, the monitoring videos of all camera devices can be obtained through this SOC, and there is no need to wake up the SOCs of other camera devices, thereby reducing the power consumption of the monitoring system.

[0045] The following combines Figures 1 to 3Describe the method for obtaining surveillance videos provided by the embodiments of the present invention. The method for obtaining surveillance videos provided by the embodiments of the present invention can be applicable to the scenario of how to reduce the power consumption of a surveillance system when viewing surveillance videos through multiple camera devices in the surveillance system. The execution subject of this method can be a camera device or a surveillance video acquisition device provided in the camera device. The surveillance video acquisition device can be implemented by software, hardware, or a combination of both. Among them, the camera device includes a main controller and a slave controller, and the camera device can be an IP Camera (IPC).

[0046] Figure 1 It is a schematic flowchart of the method for obtaining surveillance videos provided by the embodiments of the present invention. As Figure 1 shown, the method includes:

[0047] Step 101: When the main controller of the first camera device receives the surveillance instruction sent by the slave controller of the first camera device, obtain the identification information of the camera device in the surveillance instruction; the surveillance instruction is sent by the terminal device to the slave controller of the first camera device when the terminal device receives the video acquisition instruction input by the user.

[0048] In this step, the main controller of the first camera device can be, for example, an MCU, which is an infrastructure with near-field communication capabilities. The slave controller of the first camera device can be, for example, an SOC, which can process images and send the processed images to the terminal device. In addition, the SOC can also interact with the cloud server and the application (APP) in the terminal device.

[0049] When the user views the surveillance video, they can input a video acquisition instruction into the APP in the terminal device. For example, send "View the surveillance video of camera device No. 1" via voice, or directly click on the surveillance window corresponding to camera device No. 1 in the APP. After the terminal device receives the video acquisition instruction input by the user through the APP, it will send a wake-up instruction to the main controller of the first camera device. After receiving this wake-up instruction, it indicates that there is an image data service to be processed. At this time, the main controller of the first camera device will wake up the slave controller of the first camera device. After the slave controller of the first camera device is woken up, it will establish a communication connection with the APP of the terminal device. Then, the terminal device will send a surveillance instruction to the slave controller of the first camera device through the APP, and the slave controller of the first camera device will send the received surveillance instruction to the main controller of the first camera device. Among them, the surveillance instruction is generated by the terminal device based on the received video acquisition instruction. Therefore, the surveillance instruction includes the identification information of the camera device, and this camera device is the device for which the user wants to view the surveillance video. It should be noted that the content of the surveillance instruction may be the same as or different from the content of the video acquisition instruction. For example, the surveillance instruction can also be "View the surveillance video of camera device No. 1".

[0050] After the main controller of the first camera device receives the surveillance instruction sent by the slave controller of the first camera device, by parsing this surveillance instruction, it can obtain the identification information of the camera device from the surveillance instruction. For example, obtain "camera device No. 1".

[0051] Figure 2 This is one of the data interaction schematic diagrams of the surveillance system provided by the embodiment of the present invention. Taking the example that the surveillance system includes three camera devices, namely camera device 22, camera device 23, and camera device 24, for illustration. Of course, the surveillance system may also include a greater number of camera devices. For example Figure 2 As shown, the APP is installed in the terminal device 21, and the user can view the surveillance videos collected by each camera device through this APP. Assume that the first camera device is camera device 23. After the user sends a video acquisition instruction to the APP in the terminal device 21, the APP in the terminal device 21 will send a wake-up instruction to the MCU of camera device 23. After receiving this wake-up instruction, the MCU of camera device 23 will wake up the SOC of camera device 23, and then the SOC of camera device 23 will establish a communication connection with the APP of the terminal device. Then, the terminal device will send a surveillance instruction to the SOC of camera device 23 through the APP, and the SOC of camera device 23 will send the received surveillance instruction to the MCU of camera device 23. The MCU of camera device 23 will parse the received surveillance instruction, so as to obtain the identification information of the camera device that the user wants to view.

[0052] It should be noted that the first camera device in the monitoring system can be pre-set or the first camera device viewed by the user.

[0053] Step 102: When the main controller of the first camera device determines that the identification information of the camera device is the identification information of the second camera device and the second camera device and the first camera device are in the same network, the main controller of the first camera device obtains the first image data collected by the second camera device through the main controller of the second camera device.

[0054] In this step, the second camera device is a device different from the first camera device in the monitoring system. When the main controller of the first camera device determines that the identification information of the camera device is the identification information of the second camera device, it indicates that the user wants to view the monitoring video collected by the second camera device different from the first camera device. At this time, the main controller of the first camera device will determine whether it is in the same network as the second camera device, that is, whether the main controller of the first camera device can communicate or exchange data with the main controller of the second device. If it is determined that the first camera device and the second camera device are in the same network, it can be determined that the source device is the second device. At this time, the main controller of the first camera device can send an image acquisition request to the main controller of the second camera device. Based on this image acquisition request, the main controller of the second camera device acquires the first image data collected by the image acquisition sensor and sends the first image data to the main controller of the first camera device.

[0055] Among them, the image acquisition sensor can be a low-power sensor with adaptive capabilities. For example, it can be a Complementary Metal-Oxide-Semiconductor (CMOS). It can perform preliminary processing on the collected source data and send the preliminarily processed first image data to the main controller of the first camera device through the main controller of the second camera device, so that the main controller of the first camera device can send the first image data to the slave controller of the first camera device for processing. Therefore, it can ensure the fast response of the main controller of the first camera device to switch data, and can ensure the real-time and effectiveness of the video stream.

[0056] Continue to refer to Figure 2 As shown, assume that the second camera device is camera device 22 and camera device 22 and camera device 23 are in the same network, then camera device 22 and camera device 23 can communicate. The MCU of camera device 23 will send an image acquisition request to the MCU of camera device 22. Based on this image acquisition request, the MCU of camera device 22 acquires the first image data collected by the image acquisition sensor of camera device 22 and sends the first image data to the MCU of camera device 23.

[0057] Step 103: The main controller of the first imaging device sends the first image data to the slave controller of the first imaging device, and the image data is used to instruct the slave controller of the first imaging device to send the monitoring video to the terminal device.

[0058] In this step, after receiving the first image data, the main controller of the first imaging device sends the first image data to the slave controller of the first imaging device through a physical link. The slave controller of the first imaging device processes the first image data to generate a monitoring video, and sends the monitoring video to the terminal device for display, so that the user can view the video collected by the second imaging device.

[0059] Continue to refer to Figure 2 As shown, the MCU of imaging device 23 sends the received first image data to the SOC of imaging device 23. After the SOC of imaging device 23 performs image processing on the first image data, it generates a monitoring video and pushes it to the terminal device for display through the APP.

[0060] In the above method, when the user views the monitoring video of imaging device 22, the MCU of imaging device 22 does not wake up the SOC of imaging device 22, but sends the first image data to the SOC of imaging device 23 for processing. Similarly, when the user views the monitoring video of other imaging devices, there is no need to wake up the SOC of other imaging devices, and the image processing can be performed through the SOC of imaging device 23. Therefore, the power consumption of imaging device 22 and other imaging devices can be reduced, and thus the power consumption of the monitoring system can be reduced.

[0061] In the monitoring video acquisition method provided by the embodiment of the present invention, when the main controller of the first imaging device receives the monitoring instruction sent by the slave controller of the first imaging device, the identification information of the imaging device is obtained from the monitoring instruction. When the identification information of the imaging device is the identification information of the second imaging device and the first imaging device and the second imaging device are in the same network, the first image data collected by the second imaging device is obtained through the main controller of the second imaging device, and the first image data is sent to the slave controller of the first imaging device, so that the slave controller of the first imaging device performs image processing on the first image data to obtain a monitoring video. Since the user can view the monitoring video of the second imaging device by means of the slave controller of the first imaging device processing the first image data collected by the second imaging device, in this way, the slave controller of the first imaging device can process both its own image data and the image data of the second imaging device, so there is no need to wake up the slave controller of the second imaging device. Therefore, the power consumption of the monitoring system can be reduced.

[0062] Exemplarily, on the basis of the above embodiments, if the main controller of the first imaging device determines that the identification information of the imaging device is the identification information of the first imaging device, the main controller of the first imaging device acquires the third image data collected by the first imaging device, and the main controller of the first imaging device sends the third image data to the slave controller.

[0063] Specifically, if the surveillance video that the user wants to view is the surveillance video collected by the first imaging device, the main controller of the first imaging device will acquire the third image data collected by the image acquisition device of the first imaging device, and send the third image data to the slave controller of the first imaging device. The slave controller of the first imaging device performs image processing on the third image data to obtain the surveillance video corresponding to the first imaging device, and pushes the surveillance video to the terminal device so that the terminal device can be displayed through the APP.

[0064] Continue to refer to Figure 2 As shown, when the identification information of the imaging device included in the surveillance instruction is the identification information of imaging device 23, the MCU of imaging device 23 will acquire the third image data collected by the image acquisition device of imaging device 23, and send the third image data to the SOC of imaging device 23. The SOC of imaging device 23 performs image processing on the third image data and then sends it to the terminal device 21 for display through the APP, so as to facilitate the user to view.

[0065] In this embodiment, the main controller of the first imaging device can acquire the third image data and send the third image data to the slave controller of the first imaging device, so as to ensure that the image data in the first imaging device can also be processed normally, improving the reliability of the surveillance system.

[0066] Exemplarily, on the basis of the above embodiments, when the main controller of the first imaging device receives the surveillance instruction sent by the slave controller of the first imaging device, before acquiring the identification information of the imaging device in the surveillance instruction, when the main controller of the first imaging device receives the wake-up instruction sent by the terminal device, in response to the wake-up instruction, the main controller of the first imaging device wakes up the slave controller of the first imaging device, and after the slave controller of the first imaging device is woken up, the slave controller of the first imaging device establishes a communication connection with the terminal device.

[0067] Specifically, after the terminal device receives the video acquisition instruction input by the user through the APP, it will send a wake-up instruction to the main controller of the first imaging device. After receiving the wake-up instruction, the main controller of the first imaging device indicates that there is image data service to be processed. At this time, the main controller of the first imaging device will wake up the slave controller of the first imaging device. After the slave controller of the first imaging device is woken up, it will establish a communication connection with the APP of the terminal device for subsequent information interaction.

[0068] In the above manner, the slave controller of the first imaging device can be awakened to establish a communication connection with the terminal device, thereby providing a basis for subsequent information interaction. In addition, since only the slave controller of the first imaging device needs to be awakened, without awakening the slave controllers of other imaging devices, the overall power consumption of the monitoring system can be reduced.

[0069] Exemplarily, when the master controller of the first imaging device receives a monitoring switching instruction sent by the slave controller of the first imaging device, the identification information of the new imaging device is obtained in the monitoring switching instruction; the monitoring switching instruction is sent by the terminal device to the slave controller of the first imaging device when the terminal device receives a video switching instruction input by the user; the master controller of the first imaging device obtains the second image data collected by the new imaging device through the master controller of the new imaging device, and the master controller of the first imaging device sends the second image data to the slave controller of the first imaging device.

[0070] Specifically, when the user wants to switch the monitoring video, a video switching instruction will be sent to the APP of the terminal device, such as sending "switch to the 3rd imaging device" by voice, or clicking on the monitoring window corresponding to the 3rd imaging device in the APP. The terminal device will generate a monitoring switching instruction based on the received video switching instruction and send the generated monitoring switching instruction to the slave controller of the first imaging device. Since the monitoring switching instruction is generated based on the video switching instruction, the monitoring switching instruction includes the identification information of the new imaging device, such as "the 3rd imaging device", and the new imaging device is the imaging device that the user wants to view at this time. Further, the slave controller of the first imaging device will forward the received monitoring switching instruction to the master controller of the first imaging device. In this way, after parsing the monitoring switching instruction, the master controller of the first imaging device can obtain the identification information of the new imaging device.

[0071] In some embodiments of the present application, touch areas or buttons for "quick preview switching" and "full switching" can be configured on the user interface or the terminal. When the user selects "quick preview switching", the master controller of the first imaging device obtains the image sent by the master controller of the second imaging device according to the embodiments of the present application, and presents the video stream corresponding to the second imaging device to the user through the video stream interaction scheme forwarded by the slave controller of the first imaging device. When the user selects "full switching", the slave controller of the second imaging device is awakened according to the basic process of the prior art.

[0072] When the main controller of the first imaging device determines that the identification information of the new imaging device is not the identification information of the first imaging device, it will determine whether the new imaging device is in the same network as the first imaging device. If it is in the same network, it will send an image acquisition request to the main controller of the new imaging device. The main controller of the new imaging device will acquire the second image data collected by the image acquisition device of the imaging device based on the image acquisition request, and send the acquired second image data to the main controller of the first imaging device. The main controller of the first imaging device will send the received second image data to the slave controller of the first imaging device, so that the slave controller of the first imaging device processes the second image data to generate a monitoring video corresponding to the new imaging device, and pushes the generated monitoring video to the terminal device.

[0073] If the main controller of the first imaging device determines that the identification information of the new imaging device is the identification information of the first imaging device, it will acquire the third image data acquired by the image acquisition device of the first imaging device. The specific processing process can refer to the description in the foregoing embodiments and will not be elaborated here.

[0074] Continue to refer to Figure 2 As shown, when the MCU of imaging device 23 receives the monitoring switching instruction sent by the SOC of imaging device 23, it acquires the identification information in the monitoring switching instruction. Assuming that the identification information is the identification information of imaging device 24, the MCU of imaging device 23 will determine that the target device is imaging device 24, and acquire the second image data collected by the image acquisition device of imaging device 24 through the MCU of imaging device 24. Imaging device 24 will send the acquired second image data to the SOC of imaging device 23 for image processing.

[0075] In this embodiment, when switching the monitoring video, if the new imaging device is not the first imaging device, the main controller of the first imaging device can acquire the second image data collected by the new imaging device through the main controller of the new imaging device, and send the second image data to the slave controller of the first imaging device for image processing. In this way, when switching the monitoring video, it is not necessary to wake up the slave controller of the new imaging device, but the slave controller of the first imaging device is used to process the second image data collected by the new imaging device, thereby reducing the power consumption of the new imaging device and further reducing the power consumption of the monitoring system. In addition, when switching the monitoring video, the original connection does not need to be disconnected, and the communication connection between the slave controller of the first imaging device and the terminal device established before can be reused, and there is no need to establish a new communication connection between the slave controller of the new imaging device and the terminal device, which improves the speed of monitoring video switching.

[0076] It should be noted that, in the embodiments of the present invention, different operations can also be performed according to different functional configurations of the main controller and the slave controller of the first imaging device.

[0077] Specifically, when the main controller of the first imaging device only supports shooting low-resolution or low-frame-rate video streams, only low-resolution or low-frame-rate video streams are obtained and forwarded to the user during fast preview switching. When the main controller of the first imaging device supports shooting high / low-resolution or high / low-frame-rate video streams but does not support automatic exposure, a new imaging device can be controlled via near-field communication to perform high / low-frame-rate and high / low-resolution switching. Also, the exposure parameters of the new imaging device can be adjusted according to the exposure parameters configured by the slave controller of the first imaging device for the first imaging device, such as adjusting the aperture and gain, etc., so that the video stream of the new imaging device obtained can achieve automatic exposure in the case where its own main controller does not have the automatic exposure function, to ensure the picture quality. When the main controller of the first imaging device supports shooting high / low-resolution or high / low-frame-rate video streams and supports automatic exposure, the automatic exposure function of the new imaging device can be temporarily turned off according to the difference degree between the current exposure parameters of the first imaging device and the new imaging device, to save power consumption. Among them, the above difference degree can be judged by setting a difference threshold, and this difference threshold is, for example, within 10% difference. After the automatic exposure function of the new imaging device is turned off, the first imaging device and the new imaging device jointly use the exposure parameters of the first imaging device for image acquisition, and these exposure parameters can be carried in the feedback signal of successful communication packet reception. It should be understood that when the difference degree between the current exposure parameters of the first imaging device and the new imaging device is more than 10% different, their respective exposure parameters can be used, so as to ensure the image quality.

[0078] Exemplarily, on the basis of the above embodiments, when obtaining the first image data collected by the second imaging device through the main controller of the second imaging device, it can be carried out in the following manner: The main controller of the first imaging device sends an image acquisition request to the main controller of the second imaging device through the first near-field communication module in the first imaging device, and this image acquisition request is used to request image data. The main controller of the first imaging device receives the first image data sent by the main controller of the second imaging device through the second near-field communication module in the second imaging device.

[0079] Specifically, each camera device in the monitoring system is provided with a near-field communication module. Among them, the near-field communication module can be a module that supports short-range wireless communication, such as a Bluetooth or Wireless Fidelity (WiFi) module, or a digital video transmission module based on the Near Link technology. The digital video transmission module based on the Near Link technology optimizes the problems of low Bluetooth communication transmission efficiency and limited WiFi range, enabling video transmission of data within the networking range.

[0080] When the main controller of the first camera device obtains the first image data collected by the second camera device, it can send an image acquisition request to the main controller of the second camera device through the first near-field communication module set in the first camera device. After receiving the image acquisition request, the second camera device can return the collected first image data to the main controller of the first camera device based on the second near-field communication module set in the second camera device.

[0081] It should be noted that when the main controller of the first camera device obtains the second image data collected by a new camera device, it can also send an image acquisition request to the main controller of the new camera device through the first near-field communication module set in the first camera device. After receiving the image acquisition request, the new camera device can return the collected second image data to the main controller of the first camera device based on the second near-field communication module set in the new camera device.

[0082] In this embodiment, since the first image data can be obtained through the near-field communication module, the phenomenon of each camera device in the monitoring system establishing an additional network connection can be avoided, improving the speed and efficiency of obtaining the first image data.

[0083] Exemplarily, the main controller of the first camera device searches for camera devices including near-field communication modules within a preset distance through the first near-field communication module, and the main controller of the first camera device networks the camera devices including near-field communication modules with the first camera device.

[0084] Specifically, after each camera device in the monitoring system is registered in the APP of the terminal device, the MCU and image acquisition device (sensor) of each camera device will be initialized to adjust the self-gain parameter to continuously output an effective video stream. The clarity of the video stream depends on the performance of the image acquisition device.

[0085] After the first imaging device completes registration and initialization, the main controller of the first imaging device searches for imaging devices including a near-field communication module within a preset distance through the first near-field communication module. Here, the preset distance can be understood as the range supported by the first near-field communication module. After finding one, the main controller of the first imaging device forms a network with the found imaging device and the first imaging device. For example, if the first near-field communication module is a Near Link module, the main controller of the first imaging device will search for nearby imaging devices of the same mode in the SparkLink Basic (SLB) mode, so as to form a network with the found imaging device and the first imaging device.

[0086] It should be noted that after networking, for the MCU of each imaging device, each MCU in the network has a unique address, which can ensure that each MCU can be accessed and will not be accessed repeatedly. In addition, the address of each MCU will be recorded. The address of this MCU maps to the corresponding imaging device, that is, there is a one-to-one correspondence between the address of the MCU and the imaging device. Thus, based on this mapping relationship, the MCU corresponding to the imaging device can be accessed.

[0087] In addition, the above networking process can also be completed by other registered imaging devices.

[0088] In this embodiment, the main controller of the first imaging device can search for imaging devices including a near-field communication module within a preset distance through the first near-field communication module, so as to form a network with the found imaging devices, providing a communication basis for subsequent acquisition of image data and ensuring the normal acquisition of image data.

[0089] Exemplarily, on the basis of the above embodiments, when the main controller of the first imaging device determines that the second imaging device and the first imaging device are not in the same network, it sends feedback information to the terminal device through the slave controller of the first imaging device. This feedback information is used to instruct the terminal device to wake up the slave controller of the second imaging device through the main controller of the second imaging device.

[0090] Specifically, when the main controller of the first imaging device fails to find the second imaging device within the network, the main controller of the first imaging device will be unable to obtain the first image data collected by the second imaging device. The main controller of the first imaging device will send feedback information to the slave controller of the first imaging device, and the slave controller of the first imaging device will return the feedback information to the terminal device. After receiving the feedback information, the terminal device will learn that the main controller of the first imaging device cannot obtain the first image data collected by the second imaging device. At this time, the terminal device will send a wake-up instruction to the main controller of the second imaging device. The main controller of the second imaging device wakes up the slave controller of the second imaging device based on the wake-up instruction. After the main controller of the second imaging device obtains the first image data collected by the image acquisition device, it sends the first image data to the slave controller of the second imaging device. The slave controller of the second imaging device processes the first image data to generate a surveillance video and pushes the generated surveillance video to the terminal device.

[0091] Figure 3 FIG. 2 is a second schematic diagram of data interaction of the monitoring system provided by the embodiment of the present invention. As Figure 3 shown, when the MCU of imaging device 23 fails to find imaging device 22 within the network, the MCU of imaging device 23 will send feedback information to the SOC of imaging device 23, and the SOC of imaging device 23 will return the feedback information to terminal device 21. Terminal device 21 will send a wake-up instruction to the MCU of imaging device 22. The MCU of imaging device 22 wakes up the SOC of imaging device 22 based on the wake-up instruction. After the MCU of imaging device 22 obtains the first image data collected by the image acquisition device, it sends the first image data to the SOC of imaging device 22. The SOC of imaging device 22 processes the first image data to generate a surveillance video and pushes the generated surveillance video to the terminal device.

[0092] In this embodiment, when the first imaging device and the second imaging device are not in the same network, the slave controller of the first imaging device can send feedback information to the terminal device, so that the terminal device wakes up the slave controller of the second imaging device through the main controller of the second imaging device, so as to process the image data through the slave controller of the second imaging device, thereby ensuring the normal acquisition of the surveillance video and improving the reliability of the monitoring system.
