As shown in fig. 5, the algorithm cache data includes an algorithm number J (j=1 to j=m), an algorithm lock state LA, and an algorithm cache content TA.
S102, performing image shooting processing through a first thread.
The first thread has a first flag F1, and the first flag F1 is used to determine whether to end the first thread.
The acquisition locking state is used for marking whether corresponding acquisition cache data are occupied or not, and if the acquisition locking state is yes, the acquisition cache data are occupied and can be used for algorithm processing; if the acquisition locking state is no, the acquisition locking state is not occupied and can be used for image shooting processing.
And if the acquisition cache data with the acquisition locking state of no does not exist in the acquisition cache queue, judging after waiting for the preset time.

And if the acquisition cache data with the acquisition locking state being yes does not exist in the acquisition cache queue, judging after waiting for a preset time.
If the acquisition cache data with the acquisition locking state being yes exists in the acquisition cache queue, the acquisition serial number is i, the acquisition cache content of the ith acquisition cache data is subjected to algorithm processing to obtain an algorithm processing result, and the acquisition locking state of the ith acquisition cache data is set to be no.

If the algorithm cache queue contains algorithm cache data with the algorithm locking state of no, the algorithm serial number of the algorithm cache queue is j, an algorithm processing result is stored in the algorithm cache content of the jth algorithm cache data, and the algorithm locking state of the jth algorithm cache data is set to be yes.
For example, firstly, whether the acquisition buffer data with the acquisition locking state being yes exists in the acquisition buffer queue is judged, if the acquisition buffer data with the acquisition locking state being yes does not exist in the acquisition buffer queue, the waiting time is 10 milliseconds, and whether the acquisition buffer data with the acquisition locking state being yes exists in the acquisition buffer queue is judged again; if the collection cache queue contains collection cache data with the collection locking state being yes, the collection serial number is 2, the algorithm processing step is executed on the collection cache content of the 2 nd collection cache data, and the collection locking state of the 2 nd collection cache data is set to be no. Secondly, judging whether algorithm cache data with the algorithm locking state being NO exists in the algorithm cache queue, if no algorithm cache data with the algorithm locking state being NO exists in the algorithm cache queue, waiting for 10 milliseconds, and judging whether the algorithm cache data with the algorithm locking state being NO exists in the algorithm cache queue again; if the algorithm cache data with the algorithm locking state of no exists in the set cache queue, the algorithm serial number is 5, the algorithm processing step is executed on the algorithm cache content of the 5 th algorithm cache data, and the algorithm locking state of the 5 th algorithm cache data is set to be yes. Finally, judging a second mark F2, and if the second mark F2 is yes, jumping out of the loop of the second thread; if the second flag F2 is negative, the loop of the second thread continues.
S104, carrying out data transmission processing through a third thread.
The third thread has a third flag F3, and the third flag F3 is used to determine whether to end the third thread.
Judging an algorithm locking state in the algorithm cache queue, wherein the algorithm locking state is used for marking whether corresponding algorithm cache data are occupied or not, and if the algorithm locking state is yes, the algorithm cache data are occupied and can be used for data transmission processing; if the algorithm locking state is no, the algorithm locking state is not occupied and can be used for saving the algorithm processing result.
If the algorithm cache queue does not contain the algorithm cache data with the algorithm locking state being yes, judging after waiting for a preset time.
If the algorithm cache queue contains algorithm cache data with the algorithm locking state of yes, the algorithm serial number of the algorithm cache data is j, the algorithm cache content (namely an algorithm processing result) of the jth algorithm cache data is subjected to a data transmission processing step, and the algorithm locking state of the jth algorithm cache data is set to be no.
For example, firstly determining whether there is algorithm cache data with the algorithm locking state being yes in the algorithm cache queue, if there is no algorithm cache data with the algorithm locking state being yes in the algorithm cache queue, waiting for 10 ms, and determining whether there is algorithm cache data with the algorithm locking state being yes in the algorithm cache queue again; if the algorithm cache data with the algorithm locking state being yes exists in the set cache queue, the algorithm serial number is 5, the algorithm cache content (namely an algorithm processing result) of the 5 th algorithm cache data is transmitted, and the algorithm locking state of the 5 th algorithm cache data is set to be yes. Finally, judging a third mark F3, and if the third mark F3 is yes, jumping out of the loop of the third thread; if the third flag F3 is negative, the loop of the third thread continues.
S105, when the first flag, the second flag, and the third flag each indicate the end, the industrial camera ends the present control.
And clearing the acquisition buffer queue and the algorithm buffer queue, and closing the first thread, the second thread and the third thread.
In some embodiments, the industrial camera continues to perform the present control when at least one of the first flag, the second flag, and the third flag indicates not ended.
The application improves the acquisition frequency of the industrial camera by the control method of the industrial camera, and the specific time slice circulation condition which can be realized in the application is shown in the following figure 2:
at time slice 1: the 1 st frame is used for shooting images, and the 2 nd and 3 rd frames are not started yet;
at time slice 2: carrying out algorithm processing on the 1 st frame, carrying out image shooting on the 2 nd frame, and not beginning the 3 rd frame;
at time slice 3: carrying out data transmission on the 1 st frame, carrying out algorithm processing on the 2 nd frame, and carrying out image shooting on the 3 rd frame;
at time slice 4: the 1 st frame is finished, the 2 nd frame is subjected to data transmission, the 3 rd frame is subjected to algorithm processing, and the 4 th frame is subjected to image shooting;
at time slice N: ending the N-3 th frame, carrying out data transmission on the N-2 th frame, carrying out algorithm processing on the N-1 th frame, and carrying out image shooting on the N th frame;
at time slice n+3: ending the N frame, carrying out data transmission on the N+1st frame, carrying out algorithm processing on the N+2nd frame, and carrying out image shooting on the N+3rd frame;
from the above, the processing of N frames of pictures is completed in the existing working mode, and 3N time slices are required; the optimized assembly line working mode of the industrial camera control method provided by the application only needs n+3 time slices, so that the time is reduced and the efficiency is improved.
In one embodiment, the three steps of image capturing, algorithm processing, and data transmission in each frame of picture do not reach the same time length, so the length of each time slice is determined by the most time-consuming one of the steps that are currently in progress.
