Embodiment 1

[0033] refer to figure 1 and figure 2 , an intelligent video surveillance processing method with abnormal event mining function, the method comprises the following steps:

[0034] Step 1, the passive camera monitors abnormal conditions around the camera, and collects video data in the monitoring scene;

[0035] Step 2. Detect and track the moving object appearing in the monitoring scene, mark the moving object, and transmit the position and size parameters of the moving object to the active camera;

[0036] Step 3: According to the obtained position and size parameters of the active camera, according to the set parameters, judge whether it is necessary to mobilize the active camera to obtain the local close-up of the target; if the requirement of mobilizing the active camera is met, adjust the parameters of the active camera and posture, adaptively give close-up close-ups of moving targets that appear in the monitoring scene; also judge whether it is necessary to stop the m...

Embodiment 2

[0056] refer to figure 1 and figure 2 , an intelligent video surveillance processing system with abnormal event mining function, said system comprising:

[0057] The video acquisition module is used to collect video in the monitoring area, and uses a pair of master-slave cameras to work together to monitor abnormal events in the scene;

[0058] The intelligent detection module is used to detect and track the moving target in the monitoring area, and obtain the real-time position and size parameters of the moving target;

[0059] The abnormal event mining module is used to understand the behavior of the classified moving target, extract the behavioral characteristics of the moving human target itself, compare the trained behavior samples, identify its behavior and judge whether it is abnormal behavior, according to the set Determine whether an abnormal event has occurred according to the specified abnormal behavior standard. If no abnormal event occurs, it will return to con...

Abstract

The invention relates to an intelligent video monitoring method capable of exploring abnormal events, and the method comprises the following steps: 1) using a driven type camera to monitor the abnormal conditions around the camera and collect video data in a monitored scene; 2) detecting and tracking a motion target occurred in the monitored scene, marking the motion target and transmitting the position and size parameters of the motion target to a driving camera; 3) self-adaptively giving a close shot for the motion target by the driving type camera according to the acquired parameters; 4) correctly classifying the detected motion target; 5) performing behavior understanding on the classified motion target; and 6) judging whether an abnormal event occurs according to the preset standard, and triggering the alarm if the abnormal event occurs. The invention also relates to a system for realizing the method. The system provided by the invention has the function of automatically finding and analyzing the abnormal events, and has the advantages that the intelligent degree is high, and the operations of alarming and information treatment can be performed timely.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a video monitoring method and system. Background technique [0002] With the development of social economy and electronic technology and the growth of people's safety awareness, video surveillance technology has developed rapidly, and the intelligence of video surveillance system is an inevitable demand for the development of surveillance technology. [0003] At present, the traditional artificial video surveillance method is widely used, but it is not so reliable. For most people, after only 20 minutes of staring at a surveillance screen, the concentration level is not enough to notice the details of what is happening in the video. Not only that, most of the time in the surveillance video there are no events of our concern. Even if the surveillance personnel can concentrate for a long time, it will cause a serious waste of human resources. However, the traditional unsupervised ...
