Abstract
The invention discloses a kind of joining methods of monitor video, this method comprises: calling video camera to obtain video according to the position of object；Video image acquisition；Video image characteristic extracts；Video image matching；Video image fusion；The video-splicing of multichannel video camera is sent to client at video all the way.The present invention is perfectly merged and is spliced to the video pictures of multichannel video camera acquisition by way of video-splicing, keep spliced video clearly seamless, the demand that multiple people simultaneously watch same monitoring scene different angle is solved, is sufficiently met the needs of users.
Description
Technical field
The present invention relates to the joining methods of technical field of video monitoring, especially monitor video.
Background technique
In daily life, the panoramic video for obtaining monitoring area is often needed to, but due to physical factor in picture pick-up device
Limitation, a general monitoring camera can only see local scene video.If controlling holder by tele-control system with one
Fixed angular turn, thus realize viewing different direction video demand, still, when multiple people simultaneously to same monitoring scene not
When having viewing demand with angle, simple cloud platform rotation is unable to satisfy demand of the owner to monitoring.
Summary of the invention
In consideration of it, can effectively solve the above problems the present invention provides the joining method of monitor video.
It is provided by the invention that the technical scheme comprises the following steps:
Step 1: calling video camera to obtain video according to the position of object；
In this step, reference video camera is determined, when object is not in the video pictures centre bit of reference video camera
When setting, 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 center of video pictures is obtained after so that the object is located at splicing；
Step 2: video image acquisition；
Step 3: video image characteristic extracts
The first frame image group captured in this step to multiple video camera synchronizations carries out corresponding feature extraction, to first frame
Image carries out Feature Points Matching, determines accurate effective matching characteristic point combination；
Step 4: video image matches；
Shape and angular transformation are carried out to every frame image according to the matching characteristic point of frame image in first frame image group in this step
It is sheared with accurate, and establishes blank template, by the data accurate projection after each frame image cut in first frame image group to respectively
Self-corresponding blank template, and establish public data unit；
Step 5: video image merges；
In this step, one group of framing image is continuously captured from multiple video cameras, by every frame image according to respectively affiliated camera shooting
The corresponding transformation matrix of machine and shearing template carry out deformation cutting, the frame image that then every corresponding group has been deformed and cut
Carry out frame image co-registration；
Step 6: the video-splicing of multichannel video camera is exported at video all the way.
In this step, frame per second is set, each corresponding group of multiple video cameras is merged into the final image completed with new
Frame image format plays in order again, forms multiple camera chains into one effect.
The beneficial effects of the present invention are: the present invention provides a kind of video monitoring method based on video-splicing technology,
The video pictures of multichannel video camera acquisition are perfectly merged and spliced by way of video-splicing, make spliced view
Frequency is clear seamless, solves the demand that multiple people simultaneously watch same monitoring scene different angle, sufficiently meets user's
Demand.
Detailed description of the invention
It, below will be to embodiment in order to illustrate more clearly of the invention patent embodiment or technical solution in the prior art
Or attached drawing used in description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is flow diagram of the invention.
Specific embodiment
Illustrate embodiments of the present invention below by way of specific specific example, those skilled in the art can be by this specification
Other advantages and efficacy of the present invention can be easily understood for disclosed content, and the present invention can also pass through in addition different specific realities
The mode of applying is embodied or practiced, the various details in this specification can also based on different viewpoints and application, without departing from
Various modifications or alterations are carried out under spirit of the invention.
It should be noted that the basic conception that only the invention is illustrated in a schematic way is illustrated provided in the present embodiment,
Only display and related component in the present invention in schematic diagram, its assembly layout kenel may also be increasingly complex when actual implementation.
A kind of video monitoring method based on video-splicing technology of the present invention, process such as Fig. 1 institute when running
Show, detailed process is as follows:
[step S101]: 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 setting, 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 center of video pictures is obtained after so that the object is located at splicing；
[step S102]: video image acquisition；
[step S103]: video image characteristic extracts
The first frame image group captured in this step to multiple video camera synchronizations carries out corresponding feature extraction, to first frame
Image carries out Feature Points Matching, determines accurate effective matching characteristic point combination；
[step S104]: video image matching；
Shape and angular transformation are carried out to every frame image according to the matching characteristic point of frame image in first frame image group in this step
It is sheared with accurate, and establishes blank template, by the data accurate projection after each frame image cut in first frame image group to respectively
Self-corresponding blank template, and establish public data unit；
[step S105]: video image fusion；
In this step, one group of framing image is continuously captured from multiple video cameras, by every frame image according to respectively affiliated camera shooting
The corresponding transformation matrix of machine and shearing template carry out deformation cutting, the frame image that then every corresponding group has been deformed and cut
Carry out frame image co-registration；
[step S106]: the video-splicing of multichannel video camera is exported at video all the way.
In this step, frame per second is set, each corresponding group of multiple video cameras is merged into the final image completed with new
Frame image format plays in order again, forms multiple camera chains into one effect.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention, any ripe
