Tracking monitoring method and tracking monitoring device

Abstract

The invention discloses a tracking monitoring method and a tracking monitoring device. A target object can be tracked and monitored timely, and a video monitoring image comprising the target object can be acquired timely, and the reference basis can be provided for the subsequent video analysis, and the accuracy of the analysis result can be improved. The tracking monitoring method is characterized in that audio data can be acquired; the preprocessing of the acquired audio data can be carried out, and the specific parameters used for reflecting voice characteristics can be extracted from the preprocessed audio data; the specific parameters can be respectively input in various reference models, which are used for representing the categories of the voices, and the reference models matched with the specific parameters can be determined; when the determined reference models belong to the preset prior tracking reference models, the geographic positions of the speakers of the voices can be determined, and the speakers can be shot in a tracked manner by the cameras according to the geographic positions.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a tracking monitoring method and tracking monitoring equipment. Background technique [0002] With the frequent occurrence of dangerous violence and other incidents, in order to effectively prevent the occurrence of dangerous incidents or provide important information for incident handling, it is necessary to use intelligent monitoring equipment to capture video images before or during the occurrence of dangerous incidents in time. [0003] At present, in the field of monitoring, the purpose of identification and monitoring is mainly achieved through video image processing technology, which will have the following problems: [0004] First, the pictures captured by the camera are incomplete. Since the camera can only capture a limited area within a certain period of time, when a dangerous event occurs within the monitoring range of the camera, but not within the current shootin...

AI Technical Summary

Problems solved by technology

[0004] First, the pictures captured by the camera are incomplete. Since the camera can only capture a limited area within a certain period of time, when a dangerous event occurs within the monitoring range of the camera, but not within the current shooting range of the camera, the camera cannot monitor the danger. The occurrence process of the incident made it impossible for the relevant staff to deal with it in time or obtain important information

[0005] Second, the video images captured by the camera are greatly affected by the environment. When a dangerous event occurs, the ambient light is not good or the camera shakes, which may cause the captured video images to be blurred. When analyzing the obtained video images , the accuracy of the analysis results will decrease
