Problems solved by technology

[0002] At present, the video monitoring of most anti-theft systems is fixed for one direction, and the monitoring is carried out by manually watching the video. There are geographical blind spots and the monitoring site cannot be covered.
Even if some video surveillance is equipped with a pan / tilt to obtain the video of the surveillance scene through periodic rotation, there are still monitoring blind spots in time, and it is impossible to cover the surveillance scene in real time

Abstract

The invention provides a tracking and monitoring system based on sound source locating. The tracking and monitoring system is composed of a microphone array (1), an audio decoder (2), a single-chip microcomputer (3), a compass (4), a steering engine (5), a converter (6), a computer (7) and a camera (8). The microphone array (1) receives sound source audio information and inputs the sound source audio information to the audio decoder (2) to be converted into digital information to be transmitted to the single-chip microcomputer (3) to perform data analysis and processing. The single-chip microcomputer (3) controls the steering engine (5) to adjust the direction of the microphone array for accurately locating the direction of the sound source; meanwhile, the single-chip microcomputer (3) outputs the information to control the camera (8) to focus on the sound source to perform video acquisition through the converter (6) and the computer (7), and the video acquisition signal is transmittedto the computer (7) to perform image processing and display so as to realize the real-time dynamic monitoring function. The tracking and monitoring system based on sound source locating has the advantages of being global, accurate and fast without blind monitoring area.

Description

1. Technical field: [0001] The patent of the present invention is a tracking monitoring system based on sound source positioning, especially a positioning tracking monitoring system combining sound source and compass, which belongs to the technical field of electronic monitoring. 2. Background technology: [0002] At present, the video monitoring of most anti-theft systems is fixed for one direction, and the monitoring is carried out by manually watching the video. There are geographical blind spots and the monitoring site cannot be covered. Even if some video surveillance is equipped with a pan-tilt to obtain the surveillance site video through periodic rotation, there is still a monitoring blind spot in time, and the surveillance site cannot be covered in real time. 3. Contents of the invention: [0003] The purpose of the present invention is to provide a tracking and monitoring system based on compass and sound source positioning, which can realize the rapid and accura...
