Field intelligent video monitoring method, device and system integrating sound collection and recognition

Abstract

The embodiment of the present application discloses an intelligent video monitoring method, device and system for a venue that integrates sound collection and recognition, collects sound data obtained by microphones arranged in different locations in the venue; stores the sound data after preprocessing; collects and deploys different venues The video data obtained by the camera at the location is stored, and the video data is stored; the sound source is located for the sound whose amplitude exceeds the set threshold, and the feature extraction is performed for the sound whose amplitude exceeds the set threshold, and the sound is recognized and judged according to the extracted features. Whether it is an abnormal sound in the field; if it is an abnormal sound, adjust the shooting angle of the camera closest to the sound source according to the sound source position of the abnormal sound; obtain the video data captured by the camera after the angle adjustment, and record the abnormal sound The sound and the video data at the position corresponding to the abnormal sound are combined, recorded and stored, and an alarm signal is sent at the same time.

Description

Technical field [0001] The present application embodiments relate to automatic control sectors of video surveillance and video surveillance system acquisition ends, particularly, are involved in a field intelligent video surveillance method, apparatus, and system for fusion sound acquisition recognition. Background technique [0002] Traditional video surveillance system, by integrated video capture cameras, transfer to the control host through the network, controlled by manual control, view the comparison, feedback to the front-end control of the camera, or to adjust the storage files in the control host Delete playback and other operations. [0003] A camera with a rotating cloud station, currently some cameras can support automatic cruise, automatic wire sweep, rotating at a certain speed angle, ie, automatic rotating video acquisition according to the predetermined rules predetermined by the video surveillance system. [0004] Intelligent video analysis: The development direc...

Problems solved by technology

[0005] Problems in traditional video surveillance: the security personnel directly monitor the screen, which is inefficient. If you watch the surveillance for a long time, you will be easily fatigued and distracted

Unable to meet the requirements of continuous monitoring, unable to distinguish in time, easy to generate a large amount of useless video information, and the identification of useful information becomes difficult

The camera is mainly used for real-time mechanical recording of events that occur, mainly to deter offenders or obtain evidence after the event. It cannot perform real-time intervention and does not play a real-time role in monitoring.

Traditional video surveillance relying on manpower has become increasingly difficult to meet the requirements of real-time monitoring and intelligent traceability in today's society and industrial sites

[0006] Camera pan / tilt control problem: The current camera pan / tilt control performs regular rotation video collection according to preset rules, which easily makes important abnormal situations negligent, and offenders can commit purposeful crimes based on the blind spots brought about by rotation

Due to the complexity of the surveillance scene, only relying on the intelligent video surveillance system to process the image information has certain limitations. Simply relying on the single information of the video image as the analysis source for analysis and judgment may cause information blind spots, resulting in false alarms in the automatic detection and alarm system. or false report
