Problems solved by technology

[0011] The problem with the above-mentioned traditional algorithms is that in terms of identifying and understanding urban monitoring scenes, traditional algorithms are difficult to meet the needs.
These factors require the algorithm to have super generalization ability and accuracy. Traditional algorithms cannot meet these requirements on a theoretical basis. Even if they are applied, it is easy to cause false detection and missed detection of events.
[0012] The problem with the above algorithm based on deep learning is that based on the deep learning algorithm, a method with strong generalization ability can be designed to solve the problem of various event forms, but it also has high requirements for the design of the network model
Therefore, the simple application of static information of image frames has low accuracy and many false detections and missed detections in target detection and scene recognition.

Embodiment Construction

[0062] The present invention is based on the video detection method of street order events based on deep learning and motion consistency, and its method steps are:

[0063] 1) Algorithm framework:

[0064] The algorithm framework is set to polling mode, cyclically accessing the front-end video stream, collecting N frames and buffering them in the designated memory, then switching to the next video stream and buffering them in the corresponding memory space. When the internal algorithm function module thread needs to be processed, it is copied from the corresponding memory to the internal cache of the algorithm. After the processing is completed, the running results are uniformly sent to the event judgment thread for final event judgment, and then the memory data where the next video stream is located is copied, using the same way to deal with. This mode can not only ensure that the latest data collected by the current device is processed by the algorithm (the video stream is ...
