Illustratively, the user selecting image information and object recognition means for synchronization includes: the user designates an image ID to select the image information for synchronization, and designates a target recognition device ID to select the target recognition device for synchronization.

Illustratively, a user creates an image information synchronization task through a human-computer interaction device in a task management module. Further, the user selects image information and a target recognition device for synchronization through the human-computer interaction device.
Illustratively, the image information synchronization task created by the user can be one or more, and the task management module creates a task distribution scheduler corresponding to each image information synchronization task.
According to the embodiment of the present invention, in step S220, the task distribution scheduler disassembles the image information synchronization task into at least one sub-task, which may include: and the task distribution scheduler disassembles the image information synchronization task into at least one subtask according to the target identification device ID and the image ID.
Continuing with the previous example, the user-created synchronization information task may be broken down into (n1 m1+ n2 m2) subtasks.

According to the first granularity, the task distribution scheduler can disassemble the image information synchronization task into one image information which synchronizes one image in the images corresponding to one target recognition device to the target recognition device, and the image information is used as a subtask; according to the second granularity, the task distribution scheduler can disassemble the image information synchronization task into a plurality of image information which are used as a subtask and used for synchronizing one image in the images corresponding to one target recognition device; the plurality of pieces of image information of one image may be all pieces of image information of the image or partial image information of the image.
In some embodiments, the specified target identification device IDs are a and B, the specified image information is image information with image IDs of 1, 2, 3, the image information with image ID of image 1 includes image ID 1, image 1, target name 1, the image information with image ID of image 2 includes image ID 2, image 2, target age, the image information with image ID of image 3 includes image ID 3, image 3; assuming that the image information synchronization task includes a task of synchronizing the image information whose designated image IDs are 1, 2, 3 to the designated target recognition devices a and B, the task distribution scheduler breaks down the image information synchronization task into at least one subtask, which may include:
the task distribution scheduler decomposes the image information synchronization task into at least one subtask according to the target identification device ID, i.e. a and B, and the image ID, i.e. 1, 2, 3, and specifically includes:
according to the first granularity, the task distribution scheduler divides the image information synchronization task into the following subtasks:
subtask 1: synchronizing 1 image information "image 1" of image 1 to the object recognition device a;
subtask 2: synchronizing 1 image information "1 st image" of image 1 to the object recognition device a;
subtask 3: synchronizing 1 image information "object name 1" of the image 1 to the object recognition device a;
subtask 4: synchronizing 1 image information "image 2" of image 2 to the object recognition device a;
subtask 5: synchronizing 1 image information "2 nd image" of image 2 to the object recognition device a;
subtask 6: synchronizing 1 image information "target age" of image 2 to the target recognition device a;
subtask 7: synchronizing 1 image information "image 3" of image 3 to the object recognition device a;
subtask 8: synchronizing 1 image information "image 3" of image 3 to the object recognition device a;
subtask 9: synchronizing 1 image information "image 1" of image 1 to the object recognition device B;
subtask 10: synchronizing 1 image information "1 st image" of image 1 to the object recognition device B;
subtask 11: synchronizing 1 image information "object name 1" of image 1 to the object recognition device B;
subtask 12: synchronizing 1 image information "image 2" of image 2 to the object recognition device B;
subtask 13: synchronizing 1 image information "2 nd image" of image 2 to the object recognition device B;
subtask 14: synchronizing 1 image information "target age" of image 2 to the target recognition device B;
subtask 15: synchronizing 1 image information "image 3" of image 3 to the object recognition device B;
subtask 16: the 1 image information "image 3" of image 3 is synchronized to the target recognition device B.
Alternatively, according to a second granularity, the task distribution scheduler disassembles the image information synchronization task into the following subtasks:
the subtask 20: synchronizing 3 pieces of image information "image 1 (image ID), 1 st image, object name 1" of image 1 to the object recognition device a;
subtask 21: synchronizing 3 pieces of image information "image 2 (image ID), 2 nd image, target age" of image 2 to the target recognition device a;
subtask 22: synchronizing 2 pieces of image information "image 3 (image ID), 3 rd image" of image 3 to the object recognition device a;
subtask 23: synchronizing 3 pieces of image information "image 1 (image ID), 1 st image, object name 1" of image 1 to the object recognition device B;
subtask 24: synchronizing 3 pieces of image information "image 2 (image ID), 2 nd image, target age" of image 2 to the target recognition device B;
subtask 25: the 2 pieces of image information "image 3 (image ID), image 3 rd" of image 3 are synchronized to the target recognition device B.
According to an embodiment of the present invention, in step S230, the task distribution scheduler classifies the subtasks corresponding to the same target recognition device into a subtask set, so as to obtain a subtask set corresponding to the target recognition device one to one, and the method may include:
and the task distribution scheduler classifies the subtasks corresponding to the same target identification device ID into a subtask set according to the target identification device ID, so as to obtain the subtask sets corresponding to the target identification device ID one by one.
For example, when the task distribution scheduler disassembles the image information synchronization task according to the first granularity, the subtask set corresponding to the target identification device a includes subtasks 1 to 8, and the subtask set corresponding to the target identification device B includes subtasks 9 to 16; when the task distribution scheduler disassembles the image information synchronization task according to the second granularity, the subtask set corresponding to the target recognition device a includes subtasks 20 to 22, and the subtask set corresponding to the target recognition device B includes subtasks 23 to 25.
Illustratively, the method may further comprise: and removing repeated subtasks in the grouping task of each target recognition device.
Because a user may create a plurality of image information synchronization tasks at the same time as required, the tasks may have repeated operations, and the tasks are classified after all the image information synchronization tasks are split, that is, the repeated operations can be found, for example, a plurality of identical subtasks occur to synchronize 1 image information 'image 1' of the image 1 to the target recognition device B, and the like, repeated actions can be avoided by removing the repeated subtasks, the efficiency of image data synchronization is further improved, and computing resources are saved.
Illustratively, the execution modes of the image information synchronization task include a synchronous execution mode and an asynchronous execution mode, and the method 200 may further include: and the task distribution scheduler calls a main thread to execute the steps of disassembling the image information synchronization task into at least one subtask, grouping the subtasks corresponding to the same target identification device into a subtask set, and sending each grouped task to a data distribution module.
When the user creates the image information synchronization task, it is also specified whether the execution mode of the image information synchronization task is the synchronous mode or the asynchronous mode. In general, the execution mode of a plurality of subtasks divided by one image information synchronization task is the same as the execution mode of the image information synchronization task.
In some embodiments, when the execution mode of the image information synchronization task is a synchronous execution mode, the main thread waits for each subtask in each grouping task to be executed and then is closed, and the task distribution scheduler acquires the execution result of the image information synchronization task. At this time, the task distribution scheduler can obtain the execution result in the image information synchronization task in real time, so that a user can know the execution condition of the task in real time.
In some embodiments, when the execution mode of the image information synchronization task is an asynchronous execution mode, the task distribution scheduler sends each packet task to the data distribution module and then ends the main thread. At this time, the caller cannot obtain the execution result in real time in the main thread, but the main thread can quickly release the computing resource to quickly perform the next image information synchronization task, thereby further improving the synchronization efficiency.
According to the embodiment of the present invention, in step S250, the data distribution module executes each grouping task, including:
the data distribution module checks whether connection with the target identification device is established or not according to the ID of the target identification device corresponding to each grouping task;
if the target identification device which is not connected is available, acquiring basic information of the target identification device which is not connected according to the ID of the target identification device from the equipment management module of the image synchronization device, starting the SDK of the target identification device which is not connected and establishing connection with the SDK;
the device management module is used for managing basic information of the target identification device, and the basic information comprises at least one item of ID, IP address, communication port, authentication account number and password, model version of the target identification device and SDK.
The data distribution module needs to establish a connection with the target recognition device first, and then can execute a grouping task corresponding to the target recognition device, namely, a task of synchronizing image information corresponding to the target recognition device. For the target identification device which is not connected, the data distribution module needs to acquire basic information from the equipment management module, and start the SDK of the target identification device which is not connected and establish connection with the SDK by using the basic information.
Illustratively, the data distribution module executing each grouping task further includes:
the data distribution module creates a queue for each target identification device, and the queue is used for storing the grouping tasks corresponding to the target identification devices corresponding to the queue;
and acquiring and executing each subtask contained in the grouping task from the queue.
Each target recognition device is provided with a dedicated queue for storing the grouping tasks to be executed by the corresponding target recognition device. When the queues are started, each queue starts a thread for acquiring subtasks in the packet task from the current queue.
Illustratively, each subtask includes information of an execution start time thereof, and the obtaining and executing each subtask included in the group task from the queue may include:
and acquiring and executing each subtask contained in the grouping task from the queue according to the execution starting time sequence of each subtask.
It should be understood that the execution start time information of the subtasks may be a time set by a human or a time allocated automatically by the system, and is not limited herein.
Illustratively, the obtaining and executing each subtask included in the grouping task from the queue includes:
a sub-task is fetched from the queue,
detecting whether an image algorithm is being executed in a target recognition device corresponding to the grouping task;
if the target recognition device is executing the image algorithm, pausing the image algorithm and then executing the subtask;
and if the target recognition device does not execute the image algorithm, directly executing the subtask.
The method comprises the steps that a target identification device needs to pause an algorithm (the target identification device is used for detecting and identifying a target and usually executes an image algorithm) which is being executed by the target identification device, so that when a subtask is acquired from a queue, a data distribution module needs to check whether the current algorithm state of the target identification device is paused or not, if the subtask is paused, an SDK (software development kit) of the corresponding target identification device is called according to the subtask to synchronize the image information, and otherwise, the SDK of the target identification device is called first to pause the current algorithm and then synchronize the image information; and after all the grouping subtasks in the queue of the target identification device are completed, restoring the image algorithm.
In some embodiments, it may be that, when the subtasks in the queue are acquired for the first time, it is detected whether an image algorithm is being executed in the target recognition device, and if the image algorithm is being executed by the target recognition device, the image algorithm is suspended and the subtasks are executed again; if the target recognition device does not execute the image algorithm, directly executing the subtask; and when the subtasks in the queue are executed, judging whether the target identification device is executing the image algorithm or not, so as to further accelerate the image information synchronization speed and improve the synchronization efficiency, and recovering the image algorithm until all the subtasks in the queue are executed.
