Pan and tilt camera with sound identification and positioning function

Abstract

The invention relates to a pan and tilt camera with a sound identification and positioning function, which comprises a camera, a pan and tilt servo module and a pan and tilt control module, and the pan and tilt control module is respectively connected with the camera and the pan and tilt servo module. The pan and tilt camera has the following main technical characteristics that: the input end of the pan and tilt control module is connected with a sound identification and positioning module, and the input end of the sound identification and positioning module is connected with a highly directional sound pickup fixed on the pan and tilt camera. The design of the pan and tilt camera is reasonable, and the pan and tilt camera can identify and position the sound of a monitored site; when abnormal sound occurs, the pan and tilt camera can be controlled to aim at the direction of the sound source and shoot in order to timely acquire the video of an abnormal incident, and can send alarm information on the abnormal sound and the like to a monitoring center; the sound pickup distance is increased, the sound pickup effect are improved, the efficiency of capturing sound and other abnormal incidents is increased, and thereby the working efficiency of monitoring personnel can be increased.

Description

technical field [0001] The invention belongs to the field of security monitoring, in particular to a pan-tilt camera with voice recognition and positioning functions. Background technique [0002] At present, on-site monitoring through cameras has become one of the most important monitoring methods in the field of security monitoring. The most commonly used monitoring equipment is a PTZ camera with a PTZ servo device. The PTZ camera can adjust the shooting direction according to the command of the monitoring center, so as to shoot different areas of the monitoring site and send the video data back to the monitoring center for monitoring personnel to monitor. Analyze the situation on site. Existing PTZ cameras usually can only collect on-site video information. However, in the actual monitoring process, many abnormal events are difficult to find through video information. For example, abnormal sounds, as a typical feature of abnormal events, cannot be detected by cameras. A...
