Description

Technical Field

[0001] This invention relates to the field of surveillance technology, and in particular to a mimicry storage method, apparatus, electronic device, and storage medium for surveillance equipment. Background Technology

[0002] The emergence of Linux hibernation capabilities and the demand for real-time recording in 4G low-power solar-powered monitoring devices have led to the development of the cutting-edge AOV (Always On Video) technology. This technology enables solar-powered monitoring devices to output images at a rate of one frame per second or even one frame per several seconds, which to some extent meets the low-power requirements of solar-powered monitoring devices and solves the problem of monitoring devices being unable to monitor when in hibernation.

[0003] There are two ways to store the image frames generated by the monitoring equipment during full-time recording: Method 1, each image frame is stored on a storage medium such as an SD card; Method 2, the image frames acquired in AOV mode are cached in the running memory of the System on Chip (SOC). When the number of image frames stored in the running memory of the SOC reaches a certain number, the SOC does not enter a sleep state, but instead performs the operation of storing all the image frames stored in the running memory to a storage medium such as an SD card. Only after all the image frames stored in the running memory are completely stored on the storage medium such as an SD card does the SOC enter a sleep state.

[0004] However, Method 1 increases the time required for a single non-sleep state activity of the SOC, as each interaction with the SD card takes time, resulting in greater wear and tear on the SD card. Method 2, if the sleeping sensor is not woken up when the SOC is not in sleep mode, will cause recording loss due to the inconsistency between the timing of the SOC's image fetching and the timing of the sensor's image frame generation, resulting in a certain period of recording blanks. If the sleeping sensor is woken up when the SOC is not in sleep mode, the frame rate of the sensor's output image will become high, producing discontinuous segments in continuous AOV recording, while also increasing the video data volume. Summary of the Invention

[0005] This invention provides a mimicry storage method, device, electronic device, and storage medium for monitoring equipment, which enables the SOC to maintain synchronization with the image sensor outputting images in the dormant state when retrieving images during the image frame storage process, thereby achieving the same effect as when the SOC is in the dormant state.

[0006] According to one aspect of the present invention, a method for mimicking the storage of a monitoring device is provided, comprising:

[0007] When the monitoring device is in AOV mode, determine whether the on-chip system SOC is currently storing image frames in the cache queue to the storage medium.

[0008] If the SOC is currently storing image frames from the cache queue to the storage medium, then control the SOC to enter a pseudo-sleep state;

[0009] When the duration of the SOC in the mimicry sleep state reaches the mimicry sleep duration, the image sensor in the monitoring device that is in sleep state is controlled to acquire image frames at the target output frame rate.

[0010] According to another aspect of the present invention, a mimicry storage device for a monitoring device is provided, comprising:

[0011] The storage judgment module is used to determine whether the on-chip system SOC is currently storing image frames in the cache queue to the storage medium when the monitoring device is in AOV mode.

[0012] The SOC control module is used to control the SOC to enter a pseudo-sleep state if the SOC is currently storing image frames from the cache queue to the storage medium.

[0013] The image sensor control module is used to control the image sensor in the monitoring device that is in a dormant state to acquire image frames at a target frame rate when the duration of the simulated sleep state of the SOC reaches the simulated sleep duration.

[0014] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0015] At least one processor; and

[0016] A memory communicatively connected to the at least one processor; wherein,

[0017] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the mimicry storage method for monitoring devices according to any embodiment of the present invention.

[0018] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions, the computer instructions being configured to cause a processor to execute and implement the mimicry storage method of the monitoring device according to any embodiment of the present invention.

[0019] The mimicry storage scheme for monitoring devices in this embodiment of the invention determines whether the System-on-Chip (SOC) is currently storing image frames from the cache queue to the storage medium when the monitoring device is in AOV mode. If the SOC is currently storing image frames from the cache queue to the storage medium, the SOC is controlled to enter a mimicry sleep state. When the duration of the mimicry sleep state reaches the mimicry sleep duration, the image sensor in the monitoring device, which is in sleep mode, is controlled to acquire image frames at the target output frame rate. Through the technical solution provided by this embodiment of the invention, by actively waking up the image sensor at a predetermined time when the SOC is not in sleep mode, the image frame acquisition by the SOC in non-sleep mode can still maintain synchronization with the image output of the image sensor in sleep mode during image frame storage, thereby achieving the same effect as when the SOC is in sleep mode.

[0028] Figure 1 This is a flowchart illustrating a mimicry storage method for a monitoring device according to an embodiment of the present invention. This embodiment is applicable to mimicry storage in monitoring devices. The method can be executed by a mimicry storage device of the monitoring device, which can be implemented in hardware and / or software and can be configured within the monitoring device. Figure 1 As shown, the method includes:

[0029] S110. When the monitoring device is in AOV mode, determine whether the on-chip system SOC is currently storing image frames in the cache queue to the storage medium.

[0030] The monitoring equipment can be a 4G low-power solar-powered monitoring device. When the monitoring equipment is in AOV mode, both the SOC and image sensor in the monitoring equipment are in AOV mode. AOV mode includes both sleep and non-sleep states. Theoretically, the image sensor is in sleep mode when the monitoring equipment is in AOV mode. The SOC controls whether the image sensor acquires image frames, that is, it controls the switching between sleep and non-sleep states. When the image sensor is in sleep mode, the SOC is also synchronously in sleep mode to read the image frames acquired by the image sensor; when the image sensor is in sleep mode, the SOC is also synchronously in sleep mode. For example, the image sensor acquires image frames at a frequency of one frame per second, and the SOC acquires the image frames acquired by the image sensor at a frequency of one frame per second. The frame output timing of the image sensor is synchronized with the image acquisition timing of the SOC. Optionally, when the monitoring equipment is in working mode (i.e., non-AOV mode), the image sensor acquires image frames at a high frame rate. When the monitoring device is in AOV mode, it determines whether the SOC is currently storing image frames from the cache queue to the storage medium; that is, whether the SOC is currently performing the operation of writing image frames from the cache queue to the storage medium. For example, the SOC's main thread can determine whether there is an active storage thread within the SOC. If so, it can be determined that the SOC is currently storing image frames from the cache queue to the storage medium; otherwise, it can be determined that the SOC is not currently storing image frames from the cache queue to the storage medium.

[0031] Optionally, before determining whether the System-on-Chip (SOC) is currently storing image frames from the cache queue to the storage medium, the method further includes: the SOC acquiring image frames at a preset frame rate and adding the acquired image frames to the cache queue; if the write length of the cache queue is greater than a preset length threshold, the SOC is triggered to store all image frames in the cache queue to the storage medium; wherein, the write length is the number of image frames contained in the cache queue. For example, when the monitoring device is in AOV mode, the SOC acquires image frames collected by the image sensor at a preset frame rate (e.g., 1 fps) and adds the image frames to the cache queue in the SOC's running memory. The cache queue can be understood as a cache area of ​​a certain size allocated from the SOC's running memory for storing the acquired image frames. After the SOC adds the acquired image frames to the cache queue, the number of image frames currently contained in the cache queue is determined; for ease of description, the number of image frames currently contained in the cache queue is used as the write length of the cache queue. The system determines whether the write length of the buffer queue exceeds a preset length threshold. If so, the SOC is triggered to store all image frames in the buffer queue to the storage medium. Otherwise, the SOC continues to acquire image frames at a preset frame rate and adds them to the buffer queue until the write length of the buffer queue exceeds the preset length threshold. For example, if the write length of the buffer queue exceeds the preset length threshold, the main thread in the SOC, which reads image frames from the image sensor, creates a storage thread and controls the storage thread to begin writing all image frames in the buffer queue to the storage medium. Since the number of image frames written to the storage medium in the buffer queue exceeds the preset length threshold, the storage thread needs time to write all image frames in the buffer queue to the storage medium. Therefore, the SOC's main thread can determine whether the SOC is currently storing image frames from the buffer queue to the storage medium by checking if there is an active storage thread in the SOC.

[0032] Optionally, before adding the acquired image frames to the cache queue, the method further includes: performing target detection (such as vehicle detection or human detection) on the image frames; if a target is detected in the image frame, controlling the monitoring device to exit AOV mode and enter high-frequency image acquisition mode, for example, the image sensor in the monitoring device acquires image frames at a frame rate of 25fps.

[0033] Optionally, after triggering the SOC to store all image frames in the cache queue to the storage medium, the method further includes: the SOC resetting the write length to 0 and continuing to add image frames acquired at a preset frame rate to the cache queue. For example, if the write length of the cache queue is greater than a preset length threshold, the position of the image frame in the cache queue when the write length is greater than the preset length threshold is recorded, and the SOC is triggered to store all image frames in the cache queue to the storage medium. After triggering the SOC to store all image frames in the cache queue to the storage medium, the write length of the cache queue is reset to 0, and image frames acquired at a preset frame rate are continued to be added to the cache queue, wherein the write length of the cache queue is incremented by 1 for each image frame added to the cache queue. It is understood that the process of the SOC storing all image frames in the cache queue to the storage medium does not affect the SOC's continued addition of image frames acquired from the image sensor at a preset frame rate to the cache queue.

[0034] S120. If the SOC is currently storing image frames from the cache queue to the storage medium, then control the SOC to enter a pseudo-sleep state.

[0035] In this embodiment of the invention, if the SOC is currently storing image frames from the cache queue to the storage medium, the SOC is controlled to enter a simulated sleep state. This simulated sleep state can be understood as a kind of simulated sleep state, meaning the SOC only performs the task of storing image frames from the cache queue to the storage medium, but does not perform the task of reading image frames from the image sensor.

[0036] Optionally, if the SOC is currently storing image frames from the cache queue to the storage medium, then controlling the SOC to enter a mimicry sleep state includes: if the SOC is currently storing image frames from the cache queue to the storage medium, determining the current time and the last sleep wake-up time of the SOC; determining the mimicry sleep duration of the SOC based on the current time, the last sleep wake-up time, and a preset AOV sleep duration, and controlling the SOC to enter a mimicry sleep state.

[0037] For example, if the SOC is currently storing image frames from the cache queue to the storage medium, then the current time Tc and the SOC's last sleep / wake-up time Tb are determined. Optionally, when the monitoring device is in AOV mode, after the SOC reads an image frame from the image sensor and adds it to the cache queue, it determines whether the SOC is currently storing the image frame from the cache queue to the storage medium. If so, then the current time Tc and the SOC's last sleep / wake-up time Tb are determined. In this case, the current time can be understood as the time when the SOC should theoretically enter sleep mode after reading the image frame from the image sensor and adding it to the cache queue. If the SOC detects for the first time that it is currently storing image frames from the cache queue to the storage medium, the SOC's last sleep / wake-up time is the time when the SOC first enters AOV mode, such as Tb = 0.

[0038] In this embodiment of the invention, the simulated sleep duration of the SOC is determined based on the current time, the last sleep / wake-up time, and a preset AOV sleep duration. Determining the simulated sleep duration of the SOC based on the current time, the last sleep / wake-up time, and the preset AOV sleep duration includes: calculating the time difference between the current time and the last sleep / wake-up time, and using this time difference as the theoretical working time of the SOC; and determining the simulated sleep duration of the SOC based on the theoretical working time and the preset AOV sleep duration. The simulated sleep duration is the time during which the SOC only performs the task of storing image frames from the buffer queue to the storage medium, but does not perform the task of reading image frames from the image sensor.

[0039] Optionally, the simulated sleep duration of the SOC is determined based on the theoretical working time and the preset AOV sleep duration, including: if the theoretical working time is less than the preset AOV sleep duration, the difference between the AOV sleep duration and the theoretical working time is taken as the simulated sleep duration of the SOC; if the theoretical working time is greater than the preset AOV sleep duration, the AOV sleep duration is taken as the simulated sleep duration of the SOC.

[0040] For example, the time difference (Tc-Tb) between the current time Tc and the previous sleep / wake time Tb is calculated, and this time difference Tc-Tb is used as the theoretical operating time of the SOC. Based on the theoretical operating time Tc-Tb and the preset AOV sleep time Taov, the simulated sleep time Tsleep of the SOC is determined. For example, it is determined whether the theoretical operating time Tc-Tb is less than the preset AOV sleep time Taov. If so, the difference between the AOV sleep time Taov and the theoretical operating time Tc-Tb is used as the simulated sleep time Tsleep of the SOC, i.e., Tsleep = Taov - (Tc – Tb); if not, the AOV sleep time Taov is used as the simulated sleep time Tsleep of the SOC, i.e., Tsleep = Taov. It is understandable that if the theoretical working time Tc-Tb is greater than the AOV sleep time Taov, it means that the SOC takes too long to execute the storage operation of writing the image frames in the cache queue to the storage medium. Therefore, it is assumed that the SOC has theoretically performed a sleep once. Thus, the AOV sleep time Taov is taken as the SOC's pseudo-sleep time Tsleep.

[0041] Optionally, if the SOC is not currently storing image frames from the cache queue to the storage medium, the SOC is controlled to enter a system sleep state. It is understood that if the SOC is not currently performing the operation of storing image frames from the cache queue to the storage medium, the SOC is controlled to enter a system sleep state according to the normal AOV sleep logic. For example, if the SOC is not currently performing the operation of storing image frames from the cache queue to the storage medium, the SOC's image acquisition timing is synchronized with the image sensor's frame output timing. For instance, if both the image sensor's frame output rate and the SOC's image acquisition rate are 1fps, the image sensor acquires image frames from 0-200ms and is in a sleep state from 200ms to 1000ms. If the SOC is not currently performing the operation of storing image frames from the cache queue to the storage medium, the SOC reads image frames from the image sensor from 0-200ms and is in a sleep state from 200ms to 1000ms.

[0042] S130. When the duration of the SOC in the mimicry sleep state reaches the mimicry sleep duration, control the image sensor in the monitoring device that is in sleep state to acquire image frames at the target output frame rate.

[0043] In this embodiment of the invention, if the SOC is currently storing image frames from the cache queue to the storage medium, the SOC is controlled to enter a pseudo-sleep state. When the duration of the pseudo-sleep state reaches the specified pseudo-sleep duration, the image sensor in the monitoring device, which is in a sleep state, is controlled to acquire image frames at the target output frame rate. It is understood that because the SOC still needs to concurrently process the storage of image frames written to the cache queue while in a pseudo-sleep state, the image retrieval timing of the SOC and the image output timing of the image sensor are out of sync. Therefore, when the duration of the pseudo-sleep state reaches the specified pseudo-sleep duration, a control signal is actively sent to the image sensor to control the image sensor in a sleep state to acquire image frames at the target output frame rate, thereby synchronizing the image retrieval by the SOC and the image output by the image sensor. Optionally, when the duration of the pseudo-sleep state reaches the specified pseudo-sleep duration, the time when the duration of the pseudo-sleep state reaches the specified pseudo-sleep duration is recorded, and the previous sleep wake-up time Tb is updated based on this time.

[0044] Optionally, the target frame rate is greater than or equal to the initial frame rate and less than the high-frequency frame rate of the image sensor when the monitoring device is in operation. The initial frame rate is the frame rate when the image sensor is in AOV mode and the SOC is not currently storing image frames from the cache queue to the storage medium. For example, when the duration of the SOC's simulated sleep state reaches the simulated sleep duration, the image sensor in the monitoring device, which is in sleep mode, is controlled to acquire image frames at the target frame rate; wherein the target frame rate is greater than or equal to the initial frame rate when the image sensor is in AOV mode and the SOC is not currently storing image frames from the cache queue to the storage medium. For example, if the image sensor is in AOV mode and the SOC is not currently storing image frames from the cache queue to the storage medium, the initial frame rate is 1fps, meaning the image sensor acquires one frame per second. Then, when the SOC is in a pseudo-sleep state for the duration of this pseudo-sleep, the image sensor in the monitoring device can be controlled to acquire image frames at a frame rate of 1fps (one frame per second), or at a frame rate of 2fps (two frames per second). It should be noted that the target frame rate is much lower than the frame rate when the monitoring device exits AOV mode and performs full-frame recording. The advantage of this setting is that, while ensuring the SOC maintains synchronization with the image sensor in sleep mode while acquiring images, it also allows the image sensor to operate in a low-power mode, reducing unnecessary power consumption. Furthermore, it avoids discontinuous segmentation and increased unnecessary recording storage size caused by the image sensor switching to a higher frame rate after waking up.

[0045] Optionally, since the image frame position in the cache queue when the write length is greater than the preset length threshold can be recorded, after the storage thread stores the image frame corresponding to the image frame position (that is, the last image frame in the cache queue when the write length is greater than the preset length threshold) to the storage medium, the SOC resumes normal sleep logic (that is, the sleep logic when the SOC is in AOV mode and the SOC is not storing image frames in the cache queue to the storage medium). At this time, the image output logic of the image sensor and the image acquisition logic of the SOC are synchronized.

[0046] For example, Figure 2 This is a flowchart of a mimicry storage method for a monitoring device provided in an embodiment of the present invention. The description of the above embodiments can be used to further illustrate this method. Figure 2 The meaning is clear and will not be elaborated upon here.

[0047] The mimicry storage method for monitoring devices in this embodiment of the invention determines whether the System-on-Chip (SOC) is currently storing image frames from the cache queue to the storage medium when the monitoring device is in AOV mode. If the SOC is currently storing image frames from the cache queue to the storage medium, the SOC is controlled to enter a mimicry sleep state. When the duration of the mimicry sleep state reaches the mimicry sleep duration, the image sensor in the monitoring device, which is in sleep mode, is controlled to acquire image frames at the target output frame rate. Through the technical solution provided by this embodiment of the invention, by actively waking up the image sensor at a predetermined time when the SOC is not in sleep mode, the image acquisition by the SOC in non-sleep mode can still maintain synchronization with the image output of the image sensor in sleep mode during image frame storage, thereby achieving the same effect as when the SOC is in sleep mode.

[0059] If the theoretical working time is less than the preset AOV sleep time, the difference between the AOV sleep time and the theoretical working time shall be used as the simulated sleep time of the SOC.

[0060] If the theoretical working time is longer than the preset AOV sleep time, then the AOV sleep time will be used as the simulated sleep time of the SOC.

[0061] Optional, also includes:

[0062] The hibernation state control module is used to control the SOC to enter a system hibernation state if the SOC is not currently storing image frames in the cache queue to the storage medium.

[0066] Optional, also includes:

[0067] The write length reset module is used to reset the write length to 0 after the SOC is triggered to store all image frames in the cache queue to the storage medium, and to continue adding image frames acquired at a preset frame rate to the cache queue.
