Abstract

The invention provides a monitoring method based on sound recognition and a monitoring device and system thereof. The method comprises the following steps that S1: multiple types of specific sound is acquired in advance to perform sound model training so as to obtain trained sound models; S2: onsite sound is acquired, and feature extraction corresponding to multiple types of specific sound is performed on the acquired sound; S3: the extracted features and the sound models are matched and classified so as to obtain the classification result of the onsite sound; and S4: the requirement of alarm is judged according to the classification result. The insufficiency of conventional video monitoring can be compensated, and the sound and the video are cooperated so as to better monitor the complex environment in real time. Besides, the efficiency of preventing and combating criminal activities can be enhanced, and initiative and timeliness of the monitoring system for unsafe event monitoring can be ensured.

Description

technical field [0001] The invention relates to the technical fields of signal processing, speech recognition and pattern recognition, in particular to a monitoring method, device and system based on sound recognition. Background technique [0002] Traditional video surveillance methods are often used in public places, and video surveillance is relatively effective in preventing some illegal and criminal activities. However, video surveillance has the following two disadvantages: due to the negligence of the monitoring personnel, unsafe events captured by the monitoring screen will be missed; due to the two-dimensional nature of the video screen, the screen is easily blocked by disturbances. Although after the case occurs, the surveillance video of the crime scene can be collected to help investigate and collect evidence. But if the best rescue time is missed, the case will be aggravated. Therefore, it is difficult for the traditional video surveillance system to detect so...
