Description
Technical field
This utility model relates to monitoring device technical field, relates in particular to a kind of total space synchronization monitoring shooting and is
System.
Background technology
Along with the most progressive of society and the development of computing technique, video monitoring obtains in productive life each side
Application widely.At present, in electronic monitoring safety-security area, each big public place generally uses a common camera
The appointment scope of certain scene is carried out captured in real-time video monitoring.But, it is less, easy to there is field of view angle in common camera
The problem producing blind area.When the blind area of video camera occurs alert, monitoring personnel cannot check the different of generation by monitor video
Reason condition.In order to overcome these problems, conventional way is to use multiple-camera linkage correlation, in each space of a scene
Video camera is installed on position, makes the mutual correlation of video camera, make blind area reduce as far as possible.But this method there is also following defect:
(1) when there is alert, monitoring personnel need to check the picture of each video camera one by one, just can find out corresponding monitoring
Video, this reduces the efficiency of monitoring；
(2) monitoring personnel are when switching camera views, and the point of observation of real space in switching, does not also meet the mankind's yet
Observation habit；
(3) method of linkage of multi-cameras correlation, because needing to install multiple cameras in same spatial dimension, so
The complexity of construction wiring can be increased.
Additionally, public safety requires more and more higher, common video camera has been difficult to meet modern monitoring requirement, therefore
Need a kind of panoramic camera that can simultaneously monitor different visual angles.For the shortcoming of common camera, occur in that
The panoramic cameras such as high-speed ball camera, flake video camera, multi-cam panoramic camera.

But, high-speed ball camera can not carry out conduct monitoring at all levels simultaneously, can only monitor an angular field of view；By a view angle switch
To the time-dependent required for another one visual angle in the performance of motor, and the life-span of motor also affects clipping the ball
The use of type video camera.
Although the angle of visual field of flake video camera can be up to the standard 360 degree vertical 180 degree, the most vertical 220 degree, but shooting
The visual angle at the machine back side be monitor less than, do not reach the effect of conduct monitoring at all levels, equally exist blind area, and the figure of lens edge
As distortion is bigger.
The panoramic camera of multi-cam can solve the problem that lens edge scalloping is big, but the regarding of major part design
Rink corner is similar with flake video camera, and the monitoring range of the vertical direction in solid space only reaches 180 degree；And this panorama
Video camera does not accounts for the video pictures stationary problem of each photographic head substantially, transports between two photographic head when there being moving object
Time dynamic, arise that the situation that motion is inconsistent, affect monitoring effect.
According to upper, purpose total space synchronization monitoring camera system remains to be further improved really.
