Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
As shown in fig. 1, the present invention provides an image capturing method based on alarm linkage, comprising:
s11, generating a snapshot task according to the alarm signal, and putting the snapshot task into a snapshot task queue;
s12, calling a snapshot device associated with the alarm signal to execute a snapshot task according to the snapshot task;
s13, recording the time for executing the snapshot task and the number of the snapshot tasks in the snapshot task queue after the snapshot device finishes executing the snapshot task;
s14, when the time for executing the snapshot task exceeds the threshold time and the number of the snapshot tasks exceeds the threshold number value, adding the snapshot device for executing the snapshot task into the snapshot blacklist.
The invention can well improve the real-time performance of linkage snapshot, when the time consumed by the current snapshot task of the snapshot device exceeds the set time and the number of the snapshot tasks exceeds the threshold number value, the snapshot device is put into the snapshot blacklist, and when the snapshot task is executed next time, the snapshot device is not called any more, so that the subsequent tasks are not influenced.
If there are 20 tasks in the snapshot task queue, which is greater than the threshold number 15, it takes 3 seconds for one snapshot device a in the queue to perform the snapshot task, which is greater than the threshold time 2 seconds, and then the camera snapshots after the queue are 3 seconds later than the expected time, and the desired scene may not be captured. If the snapshot device a is placed in the blacklist, the snapshot device a which takes a long time to execute the snapshot task will be discarded when the next snapshot task queue has a task to be executed by the snapshot device a, so that the subsequent task is not affected.
When the snapshot device A is added into the snapshot blacklist, prompt information is generated to prompt a user of the time-consuming problem of the snapshot device. When the next snapshot task is executed, if the snapshot device associated with the snapshot task is the snapshot device in the blacklist, the corresponding snapshot task cannot be executed by calling the snapshot device.
The skilled person in the art may set the threshold time and the set number of the snapshot tasks according to actual requirements, which is not limited herein.
It should be noted that, before the snapshot task is executed, the alarm device needs to be associated with the snapshot apparatus, for example, the snapshot task C needs to be associated with the snapshot apparatus D. When the alarm signal is generated, the snapshot task C is generated, and therefore, only the snapshot device D is called to execute the snapshot task.
In an embodiment, the alarm signal may be an audible and visual alarm signal, and at this time, an identification device for identifying the audible and visual alarm signal needs to be provided, and the installation distance of the identification device is based on that the audible and visual alarm signal can be received. And generating a snapshot task after the audible and visual alarm signal is identified. Of course, in order to reduce the interference of other sound signals and light signals, the sound and light alarm signal can be set to be a signal with a specific frequency, and the signal with the specific frequency is identified by the identification device to generate the alarm signal.
In another embodiment, the alarm signal may be an electrical signal, such as a trigger signal. For example, the electronic fence generates a trigger signal when an object passes through the electronic fence, and generates a snapshot task when the trigger signal is received.
In an embodiment, the capturing task is capturing an image, and of course, the capturing task further includes processing the image, for example, when the brightness of the image is not within the desired brightness range, the capturing of the image cannot be completed, and the corresponding brightness may be adjusted, and the current brightness of the image is within the desired brightness range, so as to meet the image capturing requirement. For another example, after the capturing of the image is completed, the object in the captured image may be identified. For example, face recognition is performed on a face in a snapshot image.
In an embodiment, the method further comprises:
before the snapshot task is executed, judging whether the corresponding snapshot device is in a snapshot blacklist or not;
if the snapshot task exists, the snapshot task is abandoned, and a snapshot device associated with the next snapshot task is called to execute the corresponding snapshot task; and if the snapshot task does not exist, the snapshot task is executed through the snapshot device so as to complete image snapshot.
For example, the alarm device a1 alarm linked snapshot camera B1, the alarm device a2 alarm linked snapshot camera B2; the alarm device A1 generates an alarm and generates a snapshot task C1; the alarm device A2 generates an alarm and generates a snapshot task C2; a snapshot task C1 stuffed into the snapshot task queue; when the snapshot task needs to be executed, popping up a snapshot task C1 from the task queue; at this time, whether the snapshot camera B1 is in the snapshot blacklist is determined, and if the snapshot is in the blacklist, the snapshot task C1 is discarded, and meanwhile, the snapshot task C2 pops up, and the snapshot task is executed by the snapshot camera B2.
In an embodiment, the method further comprises: and emptying the snapshot blacklist at intervals.
The period of time may be a fixed time point, and may be a fixed time point, such as 12: 00 o' clock or wednesday of the week, etc. Of course, a period of time may also be every other period of time, for example, every two hours, to perform the clearing process on the snapshot blacklist. Therefore, the camera with accidental problems can be released from the blacklist library, and normal snapshot work can be recovered.

If the snapshot device a is placed in the blacklist, the snapshot device a which takes a long time to execute the snapshot task will be discarded when the next snapshot task queue has a task to be executed by the snapshot device a, so that the subsequent task is not affected.
When the snapshot device A is added into the snapshot blacklist, prompt information is generated to prompt a user of the time-consuming problem of the snapshot device. When the next snapshot task is executed, if the snapshot device associated with the snapshot task is the snapshot device in the blacklist, the corresponding snapshot task cannot be executed by calling the snapshot device.
