Description
Technical field
The invention belongs to security system technical fields, and in particular to merge the Streaming Media clothes of augmented reality label in video
Business method and system.
Background technique
Monitoring is every profession and trade key sector or the physical basis that important place is monitored in real time, and administrative department can pass through it
Valid data, image or acoustic information are obtained, the process of paroxysmal abnormality event is timely monitored and remembered, to mention
For efficiently, in time commander and height, arrangement police strength, settle a case.
With rapid development and popularization that current computer is applied, the whole world has started one powerful wave of digitalization,
The various equipment digitalized primary goals for having become security protection.Most of monitoring system has upgraded number at present
Word monitoring system, digital monitoring alarm are mainly characterized by networking or IPization.Digital camera and video storage unit,
Video display tube manages unit and forms local area network by the network switch, and video storage unit accesses digital camera by IP address
Machine obtains video flowing and stores.Video is shown and administrative unit then realizes that video access and display to digital camera are real-time
Video.In addition quick-searching, a variety of video recording mode set-up functions, automated back-up, holder/lens control function etc. function are also equipped with
Energy.
Digital monitor system can substantially be divided into digital camera (also having referred to as front end), video storage and video display tube
(also having referred to as rear end) several parts are managed, each section, at local area network, realizes digital monitor system by group of switches.Video show and
Administrative unit is commonly referred to as video management platform, usually runs in a software form on computers.Behaviour of the monitoring personnel to video
Make and management is all carried out by this platform software.
It is superimposed the information of some fixations in video, this is function very common at present.Superposition for information, either
For the video or digital video of simulation, all there is a feature, position of the information being exactly superimposed in video pictures is
Fixed, it will not change with the rotation of camera lens.In PTZ camera, picture is with reality observed by cloud platform rotation
Spatial position is entirely different, and the information being superimposed then is fixed on picture.Therefore the fix information of this superposition can not
The information of actual things in true display picture.Meanwhile the characteristic that the information of this superposition does not interact, it can only be with certain
Fixed mode shows information, such as display time, character.
It is specific to correspond to some in the real space and the space of reality for real-time pictures shown by PTZ camera
Things.User can check the relevant information of the specific things by the virtual label with interaction capabilities, such as picture, text
Word, video, this can bring very big convenience to user.This function is that original simple superposition character information can not
It realizes.
Summary of the invention
In order to solve the above problems existing in the present technology, it is an object of that present invention to provide merge augmented reality in video
The stream media service method and system of label, the invention belongs to the processing in the later period of the camera video of a kind of pair of security industry to do
Method, certain saying are after being decoded to the video stream data from video camera, while obtaining the PTZ letter from video camera in real time
Breath is superimposed virtual reality mark, and again so that carrying out virtual reality identifies the positioning in video pictures in video pictures
It encodes in the form of streaming media service for users to use.When user obtains video, it can see with virtual reality mark
Video, virtual reality mark be to be embodied in true things in video pictures, can with video camera turn to variation it is mobile, hiding or
Show, meanwhile, virtual reality mark, which has, clicks interaction characteristic, and user can click video pictures when watching video
Virtual reality mark, virtual reality mark then can execute interactive action according to effective event of clicking.
