Abstract
The invention discloses a kind of video frequency monitoring method based on video-splicing technology, this method includes：Receive the operational order to the object in monitor video picture that client is sent；According to the position of object, video camera is called to obtain video；Video image acquisition；Extract video features and carry out the matching analysis；Carry out image co-registration；The video-splicing of multichannel video camera is sent to client into video all the way.The present invention to the video pictures of multichannel camera acquisition perfectly merge and splice by way of video-splicing, make spliced video clearly seamless, many personal demands watched simultaneously the different angles of same monitoring scene are solved, the demand of user is fully met.
Description
Technical field
The present invention relates to technical field of video monitoring, particularly a kind of video frequency monitoring method based on video-splicing technology.
Background technology
In daily life, need to obtain the panoramic video of monitor area often, but be due to physical factor in picture pick-up device
Limitation, a general monitoring camera can only see local scene video.If controlling head by tele-control system with one
Fixed angular turn, so that the demand of viewing different azimuth video is realized, still, when how personal while to same monitoring scene not
When having viewing demand with angle, simple cloud platform rotation can not meet demand of the owner to monitoring.
The content of the invention
In consideration of it, the invention provides a kind of video frequency monitoring method based on video-splicing technology, can effectively solve
State problem.
The technical scheme that the present invention is provided comprises the following steps：
The first step：Receive the operational order to the object in monitor video picture that client is sent；
Second step：According to the position of object, video camera is called to obtain video；
3rd step：Video image acquisition；
4th step：Extract video features and carry out the matching analysis；
5th step：Carry out image co-registration；
6th step：The video-splicing of multichannel video camera is sent to client into video all the way.
The beneficial effects of the present invention are：The invention provides a kind of video frequency monitoring method based on video-splicing technology,
The video pictures of multichannel camera acquisition perfectly merge and splice by way of video-splicing, make spliced regard
Frequency is clear seamless, solves many personal demands watched simultaneously the different angles of same monitoring scene, fully meets user's
Demand.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of patent Example of the present invention or technical scheme of the prior art
Or the accompanying drawing used in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is schematic flow sheet of the invention.
Embodiment
Illustrate embodiments of the present invention below by way of specific instantiation, those skilled in the art can be by this specification
Disclosed content understands other advantages and effect of the present invention easily, and the present invention can also pass through specific realities different in addition
The mode of applying is embodied or practiced, the various details in this specification can also based on different viewpoints with application, without departing from
Various modifications or alterations are carried out under the spirit of the present invention.
It should be noted that the diagram provided in the present embodiment only illustrates the basic conception of the present invention in a schematic way,
The component relevant with the present invention is only shown in schematic diagram, its assembly layout kenel may also be increasingly complex during its actual implementation.
A kind of video frequency monitoring method based on video-splicing technology of the present invention, flow such as Fig. 1 institutes when it runs
Show, idiographic flow is as follows：
【Step S101】：Receive the operational order to the object in monitor video picture that client is sent；
【Step S102】：According to the position of object, video camera is called to obtain video；
In this step, reference video camera is determined, when object is not in the video pictures centre bit of reference video camera
When putting, judge whether to call video camera；If desired adjacent camera video is called, the video pictures of reference video camera are adjusted
With the video-splicing angle of adjacent camera, the object is set to be located at the center for obtaining video pictures after splicing；
【Step S103】：Video image acquisition；
【Step S104】：Extract video features and carry out the matching analysis；
In this step, the first two field picture captured to multiple video camera synchronizations carries out the extraction of individual features, to first frame
Image carries out Feature Points Matching, it is determined that accurate effective matching characteristic point combination；
【Step S105】：Carry out image co-registration；
In this step, will be per two field picture according to the respective affiliated corresponding transformation matrix of video camera and shearing template progress deformation sanction
Cut, two field picture fusion then is carried out to the two field picture that each correspondence group has been deformed and cut；
【Step S106】：The video-splicing of multichannel video camera is sent to client into video all the way.
The above-described embodiments merely illustrate the principles and effects of the present invention, any ripe not for the limitation present invention
Know the personage of this technology all can carry out modifications and changes under the spirit and scope without prejudice to the present invention to above-described embodiment, because
This, those of ordinary skill in the art is complete without departing from disclosed spirit and institute under technological thought such as
Into all equivalent modifications or change, should by the present invention claim be covered.
