Abstract

The invention particularly relates to an audio / video combined monitoring method and a system thereof, belongs to the technical field of industrial environment monitoring, and aims to solve the problems in the prior art, for example, the monitoring is only conducted by video monitoring operators on duty, who are easy to be fatigue and hardly identify places with potential safety hazards, moreover, video monitoring is limited by functions and viewing angles, so that the potential hazard cannot be found in time, thereby missing rescue opportunities. The audio / video combined monitoring method uses audio signals and video signals at the same time to conduct environmental monitoring, and guides the operators on duty to selectively observe video windows by using the identification results of the audio signals. The processing method of the audio signals comprises the following steps: (1) feature extraction, (2) model training, (3) sound classification, (4) online study, and (5) hazard rating evaluation.

Description

technical field [0001] The invention belongs to an industrial environment monitoring technology, in particular to an audio-visual combined monitoring method and system. Background technique [0002] At present, the video monitoring equipment used in the industrial environment is mainly composed of a video camera and a monitoring display terminal. Through the continuous and cyclic inspection of various scenes in the monitoring place by the on-duty personnel, abnormal situations are judged. In recent years, with the advancement of image processing technology, video real-time analysis systems with certain intelligent analysis functions have also been successfully applied. For example: use the comparison of consecutive frames to judge whether there is a moving object in the video scene to remind the attention of the on-duty personnel; or add an infrared detection device to judge whether there are people or vehicles, etc. These measures help the on-duty personnel to increase the...
