Spherical sensor and audio remote detection method and system applying spherical sensor

Abstract

The invention provides a spherical sensor. The spherical sensor comprises a driving module for receiving a moving instruction sent by a control terminal, and driving the spherical sensor to move to a target area according to the moving instruction; a video acquisition module for receiving a target locking instruction sent by the control terminal, locking a target object according to the target locking instruction and acquiring video information of the target object; an audio restoration module for extracting audio information which is environmental audio information of the target area from the video information of the target object; and a wireless communication module for transmitting the audio information to the control terminal. Moreover, the invention also provides an audio remote detection method and system applying the spherical sensor. Through adoption of the spherical sensor, remote detection of audio signals can be realized.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to a spherical sensor, an audio remote detection method and system using the spherical sensor. Background technique [0002] With the increase of terrorist cases at home and abroad in recent years, incidents such as hostage-taking have occurred frequently, causing a large number of innocent casualties. In the hostage rescue scene, in order to successfully subdue the robbers without harming the hostages, it is necessary to quickly and accurately understand the specific situation of the hostage-taking scene in order to formulate a detailed rescue plan. At present, the monitoring of hostage-taking scenes is mostly realized through telescopes or closed-circuit monitoring systems. However, the above-mentioned monitoring methods are easily limited by the environment, for example, the audio information of the hijacking scene cannot be obtained by means of telescope monitoring, whic...

Problems solved by technology

However, the above-mentioned monitoring methods are easily limited by the environment, for example, the audio information of the hijacking scene cannot be obtained by means of telescope monitoring, which is not conducive to accurate judgment of the scene

In addition, although some closed-circuit monitoring systems have both video and audio signal collection functions, the monitoring equipment of the closed-circuit monitoring system is usually installed in a relatively conspicuous position, which is easily damaged by man-made
