Abstract
The device collects sound by using two or more microphones which are arranged in different directions on a plane or a space as a sound collector, the relative position of each microphone in the collector is fixed and is subjected to label distinguishing, the spatial position of a sound source can be uniquely determined according to the time difference and the sound intensity difference of the sound collected by different microphones, and the camera can be controlled to rotate to find a target and track and shoot the target according to the position information. Because the temperature has an influence on the propagation speed of sound, correction can be provided for the system according to the acquired temperature value, and the accuracy of the system is improved.
Description
Art
The present invention relates to the field of to carry out the various monitoring such as security protection, videograph and image acquisition in the mode such as video, image.
Background technology
At present, known video monitoring is combined by image acquisition part, storage area and hop to form.Image acquisition part wherein mainly contains two kinds of modes: one adopts fixing camera mode; A kind of is the mode adopting uniform rotation scanning.Also have a small amount of mode of image procossing that adopts to catch dynamic object, realize tracing and monitoring.These modes have respective drawback, and wherein first two mode can not the dynamic tracking of realize target; Though rear a kind of can the tracking of realize target because can not conduct monitoring at all levels simultaneously, therefore there is two problems: one is: the problem that whether can find target at the very start; Two is the mode tracking targets having image procossing, very high to the requirement of data processing equipment, added cost.
Summary of the invention
In order to overcome the deficiency of existing video monitoring system, inventor design invented a kind of adopt two or more in plane or space different towards microphone as sound collector, the intensity of the sound arrived according to different microphones different and time difference, because the position of the microphone receiving sound is relatively fixing, therefore the position of occurring source relative to sound collector can just be determined, therefore just can control camera to turn to, reach the object of effective tracking target.
The technical solution adopted for the present invention to solve the technical problems
This device by be equipped with two or more in plane or space different towards microphone gather sound as sound collector, the relative position of each microphone in collector line label of fixedly going forward side by side is distinguished, mistiming and the sound intensity of sound is gathered according to different microphone, uniquely can determine the locus of sound source, and camera can be controlled according to this positional information track up is carried out to target.Because the velocity of propagation of temperature on sound has impact, therefore according to the temperature value collected, for the accurate localization of sound source of this system provides correction, this system accuracy can be improved.
Beneficial effect of the present invention
This device can be used as the ingredient of the video such as security protection, monitoring, image capturing system, controls image collecting part and finds target and carry out real-time follow-up, the system that also can be positioned by sound as other.This apparatus structure is simple, with low cost, is adapted at using in people's daily life promoting.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is principle of the invention schematic diagram.
Fig. 2 is this apparatus structure composition diagram.
Fig. 3 is the structural drawing of this device and traditional monitoring mode complementation.
Fig. 1 indicates the situation of two microphones, sound source Wei L1 and L2 to the distance wind of two microphones, because the distance of L1 with L2 is different, therefore same sound source arrives the time difference of two microphones, two microphones collect intensity of sound is also different, according to above 2 or the wherein not same differentiation can carrying out sound source position, analogize during multiple microphone.
Fig. 2 is the structural representation of this device, the support of still image collecting device and the position of sound collector, rotatable image capture device installed by the support of image capture device, the sound source position just can determined by sound collector, controls image capture device to detection realization of goal oriented acquisition and tracking.
Fig. 3 is that this device and traditional monitoring mode realize complementary structural drawing, can prevent from utilizing Sound error navigational figure collecting device to turn to.
Embodiment
Illustrate according to above-mentioned accompanying drawing, two or more microphone fixed space position, can the dimensional orientation of resolution sound source of maximal accuracy, the position of fixing sound collector and image acquisition support, thus unique image capturing system that controls accurately can be realized to the tracking of target, control model can be gathered with traditional images to be combined, both can prevent from utilizing Sound error to guide the image capture device of this device to turn to, above-mentioned two problems in traditional acquisition mode can have been made up again.
Claims (4)
1., based on a video monitoring system for sound localization, it is characterized in that: this system by two or more in plane or space different towards microphone as sound collector.
2. the video monitoring system based on sound localization according to claim 1, it is characterized in that: the time that same sound source arrives two microphones is different, two microphones collect intensity of sound is also different, can auditory localization be carried out according to above 2 or wherein not same, analogize during multiple microphone.
3. the video monitoring system based on sound localization according to claim 1, is characterized in that: by the positional information of the sound source of acquisition, controls image collecting part and rotates discovery and tracking target.
4. the video monitoring system based on sound localization according to claim 1, is characterized in that: the microphone position in sound collector is fixed, and the position of sound collector and the support of video acquisition part are fixed.
